Public Values in Water Law: A Case of Substantive Fragmentation?

Horizontal fragmentation, from a public-values perspective, is a quite well-documented phenomenon in international (water) law. However, the literature does not provide any insight into vertical or substantive fragmentation, i.e. differences in the protection of public values at the various institutional levels. This article assesses whether there is substantive fragmentation in water law at the international, the European, the sub-regional (Danube River Basin), and the Dutch domestic level. To this end, first a working definition of the concept of ‘public water values’ will be formulated. Subsequently, this article will draw conclusions regarding the degree of substantive fragmentation in water law across the institutional levels mentioned, based on an in-depth analysis of relevant sources of water law. The article will not present an exhaustive overview of public water values, but elaborates on a number of core values in water law.


Introduction
Water is often characterized as a public good for various reasons: it can benefit large numbers of people without diminishing its quality, it is a natural resource, it serves the basic needs of individuals, and is essential for maintaining the ecosystem.The underlying idea behind these reasons is the need to ensure that certain publicly important values, i.e. public values, are respected.Although there is a general idea about what these values might be, it is still unclear what the concrete public water values are and to what extent these are actually incorporated in the various dimensions of water law (economic, environmental and social) and at the different institutional/governance levels (international, regional, sub-regional and domestic).Given these dimensions and levels of governance, water law is therefore often described as horizontally and vertically fragmented.The term 'fragmentation' is often associated with negative consequences; the general idea is that diverging approaches would lead to inconsistent, incoherent and ineffective results as well as to legal uncertainty.These negative connotations then raise the question whether institutional fragmentation negatively affects the protection of public values.
Against this background, the following research question will be addressed in this article: Is there substantive fragmentation regarding the protection of public water values across different institutional levels, and to what extent?Hence, the main purpose of this article is twofold: (1) to provide a working definition of and a theoretical framework for the identification of public values; and (2) to explore which public values are being protected at the different levels and across two main dimensions.To this end, this article will provide insights into the different levels of governance on the basis of some representative examples.In addition to exploring public values within international water law (international level), the relevant water law norms in the European Union (regional level), in the Danube River Basin (sub-regional level) and in the Netherlands (domestic level) will also be analysed.Until now, there has been no extensive and integral assessment of public values in water law across the levels mentioned. 1This article, therefore, aims to fill this gap by carrying out a comparative assessment of water law across these levels focusing on the environmental and social dimension of water law.
In order to achieve these purposes, the article will first set out the conceptual contours of what public values are and how they can be approached (Section 2).The analysis of the representative examples at the different levels has been based on this conceptual framework: the public values that are enshrined in or that underlie the legal norms will be identified in Table 1, and a selection of them will be elaborated in further detail (Section 3).The intention is not to exhaustively list all public values that are somehow incorporated in water law.Rather, the analysis focuses on identifying those public values that are specifically important for the water sector.Finally, the article will conclude with a brief assessment of the status of substantive fragmentation of public values incorporated at the different levels of water law (Section 4).

Fragmentation and its effects
International law is often described as fragmented, which is usually not regarded as a positive phenomenon. 2 Fragmentation or diversification of international law is meant to describe the specific feature of international law that its various fields, such as human rights law, economic law, environmental law etc., function in isolation, meaning that although they are part of the same family, there is hardly any relationship between these fields of law.
The academic literature on fragmentation and its possible effects is rather rich. 3A significant segment of this literature warns of the possible negative consequences of the fragmented structure of international law and pleads for de-fragmentation through different techniques.Among these consequences the following are most often mentioned: legal uncertainty, threat to the 'credibility, reliability and, consequently, authority of international law' , 4 or negative implications for the effectiveness of the law. 5It seems likely that these effects would also apply to the other levels of law examined in this paper.
The fragmentation aforementioned is of a horizontal nature.Another, less well-documented, kind of fragmentation is that of a vertical or substantive nature, meaning that certain public values that are protected in the law at a (higher) institutional level lack protection at a (lower) institutional level.A case of substantive fragmentation might, at first, give rise to the conclusion that public water values are 'underprotected' at a certain institutional level.In turn, this not only indicates a poor protection of generally accepted public values, but also a poor pursuance of public virtues, such as achieving high standards of human health and environmental protection.This might increase or maintain the risk of water-related environmental or human health hazards.Simply embedding public water values in the law -but especially the lower -institutional levels may help to decrease these social and environmental problems.
The purpose of this paper is not to address whether the consequences of horizontal and substantive fragmentation have occurred or could occur.Rather, the paper accepts that horizontal fragmentation may lead to the above-mentioned consequences, and thus examines whether there is a risk of substantive fragmentation.Put differently, it is hypothesised that these consequences are or could be real, and it explores the nature of existing fragmentation with regard to the public values vertically protected at the various levels.Should there be great variation and diversification in terms of these values, it is presumed that it could have negative effects on both the legal system and society, as indicated above.

Water and water services as public goods
Historically, water law has developed in fragments with the effect that it is now seen as incorporating different dimensions (horizontal fragmentation) at different levels (vertical fragmentation). 6Although these dimensions are qualified by different names by different authors,7 they can essentially be linked to the three main features of water: water as an environmental unit, water as an economic unit and water as a 'social/human' unit. 8The existing instruments seem to reflect these three main features of water, sometimes in a somewhat more separated manner and sometimes somewhat more integrally.For instance, at the international level the so-called water conventions regard water mainly as an environmental unit (environmental dimension), 9 while the approach of the World Bank 10 and the World Trade Organisation 11 mainly deals with water as an economic unit (economic dimension), and the rather recent acknowledgment at the UN level of the human right to water and the other related human rights instruments seem to regard water as a 'social/human' unit (social dimension). 12At the other levels of water law these dimensions are addressed in a more integral manner.Both the European Water Framework Directive (WFD) 13 and the Dutch Water Act (WA), 14 for instance, contain elements that can be placed in all three dimensions. 15he horizontally fragmented nature of water law implies that, on the one hand, there is and there can be overlap between these dimensions, and that, on the other hand, these dimensions have adopted and can adopt separate rules with a focus on the particular water feature they address. 16For instance, the international treaties in the environmental dimensions address state relationships with a focus on the protection of the rivers and river basins, 17 which are regarded as public goods.The international rules in the economic dimension primarily focus on economic issues, and water, accordingly, is often and mainly seen here as an economic good. 18Nevertheless, the World Bank's documents indicate that there has been, although implicitly, a shift from regarding water as an economic good 19 to water as a public good (or sometimes regional public good) 20 in the World Bank's approach.Finally, the social dimension explicitly deals with water as a human right or as a source essential for development, although with a focus on the need to protect the environment.In this dimension water is regarded as a public good, more specifically as a social and cultural good. 21In a similar manner, the sub-regional or river basin level also focuses mainly on the environmental dimension of water, incorporating some social justice features, while hardly embedding the economic dimension of water.In the Danube River Basin, for instance, water is also characterised as a public good.Also in Europe and the Netherlands, water is seen as a public good.The first consideration of the Preamble of the WFD mentions water as a 'common heritage' . 22In the Netherlands (surface) water is traditionally considered a 'res communes omnium' , which as a rule cannot be privately owned 23 and is subject to use by all. 24ccordingly, these horizontal dimensions at the different levels regard water as a public good, which implies that water is generally seen as 'a commodity the benefit from which is shared by the public as a whole' . 25In these general terms, not only water, but also water safety -the protection from water -and other 'water services' , such as waste-water purification, could be regarded as a public good. 26Moreover, water can -in some circumstances -also be defined as a global public good.According to the definition of Kaul, Grunberg and Stern, '[o]f particular importance is the question of who should be the beneficiaries -the publicum -of a public good in order for it to qualify as global.' 27 In their view: '[A] pure global public good is marked by universality -that is, it benefits all countries, people and generations.An impure global public good would tend towards universality in that it would benefit more than one group of countries, and would not discriminate against any population segment or set of generations.' 28 The question whether or not water is a pure global public good might not need to be answered, as it is clear that it does benefit a broader group of states, people and generations at each level of governance. 29ndeed, water is of global importance with regard to which all 'states have a duty to cooperate in developing and implementing effective legal regimes to address the transboundary dimension of the problem' . 30It also 'includes an inter-generational dimension that considers the use and conservation of the matter concerned in a long-term perspective' , 31 and -last but not least -'the public has a critical interest in water' . 32In addition to being a (global) public good, it moreover has been argued that water should be seen as a common heritage 33 or common concern of humankind, 34 or public commodity. 35 conclusion, one could argue that irrespective of the specific terms used to describe the public nature of water, they all refer to the 'common interest' that is inherent in water and they all aim to envisage a regime that could provide appropriate protection for such a special 'good' .Accordingly, water can be described as a 'global public good' , emphasising the universal character of the common interests in water and water services.

Public values in general
Public goods are intrinsically linked to public values.Because water is so essential for life on earth, people attach many values to it.Admittedly, many definitions and many synonyms exist for 'public values' .Moreover, different terms might also be associated with 'public values' , which, however, cover distinct issues. 36All in all, this article does not aim to give an all-decisive definition.Instead, a working definition will be devised that relates closely to the most commonly used concepts.' A society's "public values" are those providing normative consensus about (a) the rights, benefits and prerogatives to which citizens should (and should not) be entitled; (b) the obligations of citizens to society, the state, and one another; and (c) the principles on which the governments and policies should be based.' 37 From this definition three main aspects of the 'publicness' of values can be discerned.First, it has been argued that '[f]or a value to be called "public", there has to be a collectivity, an aggregation level that can benefit from the protection of this value.' 38 It is clear that this aspect is a sliding scale as there may be some debate about what a 'collectivity' is.For instance, if someone finds water valuable because he or she likes to look down in still ponds to admire his or her own reflection, this would probably make having a tranquil surface water at hand a private value.If, however, more people tend to find this valuable, the value becomes more public. 39It may be clear that the more generally the value is formulated, the more people will agree on its importance, i.e. the more public the value becomes.Having water available, for instance, would be much more public a value, since everyone needs it at least to do something with it.
Second, it is of importance whose opinion should influence or be relevant to decision-making in terms of values.In this regard, Bozeman's definition includes that a value is public when there is normative consensus within a society about 'the rights, benefits, and prerogatives to which citizens should (and should not) be entitled' and about 'the obligations of citizens to society, the state and one another' .This relates closely to the first part of the definition: it matters that 'the public' holds a certain value dear.The added value, however, is that the public should also somehow express consensus about 'who gets what' and about the conduct that can be expected from the people with regard to the value at stake.In order for the example mentioned above, 'having water available' , to be considered a public value, it should also include some more concrete decisions about rights and conducts, such as 'having enough water available for everyone' .As far as this aspect is concerned, public values represent a stable and nonvolatile communis opinio, which could, of course, change over time and differ among societies, regions, and (political) circumstances. 40hird, a value is public when it provides normative consensus in a society about 'the principles on which governments and policies should be based' . 41Hence, it should not only be a value that is shared by the people and that guides their conduct, but it should also be a guiding principle or guideline for governance and lawmaking. 42It could, for instance, be a guiding principle for the government to ensure that all people have sufficient water.Importantly, if the first two criteria are fulfilled, often the third one will be too.If most people agree about something they hold valuable, and about what they are entitled to in relation to others, governments will soon deem it fit to ensure that this communis opinio is respected and reflected in their policy and law.Generally, this is only different if the communis opinio is about something trivial that needs no protection at a broader policy level, or if it concerns a value in an area where government authority is disputed for some reason.
Concerning the second aspect of defining public values, 'values' might be best defined by contrasting and comparing them with virtues. 43The category of virtues concerns the broad and overarching concept of well-being, and could, very succinctly, be defined as 'what is worth pursuing from some or someone's perspective' . 44Virtues can, of course, be of an individual nature (for instance happiness), but in this article the focus is on what is worth pursuing from a societal perspective.Peace, safety, financial stability, public health, and environmental protection could, for instance, be considered virtues from this perspective.These 'public virtues' generally imply government responsibility, and most of them, one way or the other, essentially underlie concrete policies as a generic 'goal-setting mechanism' .So in this view, public virtues give direction to and provide for a thematic framework for law and policy-making. 45Based on this concept of public virtues, one could only reasonably expect that in a society there is law and policy on, for instance, public health, but what concrete aims this law and policy substantially pursue, from this perspective, remains unclear.What concrete level of public health, for instance, will be strived for, and through which 'channels' and by which means will this be ensured?This is where public values come into play.Public values are respected in the interest of the public, with the aim to contribute to the achievement of some degree of societal well-being.As public virtues determine what is worth pursuing from a societal perspective, public values -from the same perspectivedetermine how these virtues should be pursued and, moreover, how these should substantially be given shape in concrete decision-making.From a societal perspective, for example, aiming to achieve a high level of environmental protection is a public virtue, which should, inter alia, be pursued by the government in a transparent manner: the public value in this case is transparency.Also the pursuit of a high level of public health could be considered a public virtue, which, inter alia, includes that anyone should be entitled to a sufficient quantity of clean water for personal use.In simple terms, the public virtue of a high level of public health can be achieved through the value of providing a sufficient amount of clean water.In conclusion, public values impose procedural and substantive requirements on government behaviour concerning the pursuit of a certain degree of societal well-being in order to qualify it as 'legitimate' from a perspective of societal morality. 46though the concrete public values might be up for debate, there actually is agreement that these include both procedural and substantive public values.The former category refers 'to the way the public sector should act and to standards that the process of government action should meet' . 47In this respect, reference could be made to the concept of 'good governance' , as these principles can be seen as (mainly) procedural public values. 48The category of substantive public values is more sector-specific and encompasses substantive standards that should be met in law and policy in order for them to be considered 'legitimate' from the perspective of societal morality.It has been noted, however, that there is no clear-cut distinction between procedural and substantive values and that they might overlap. 49In addition, it can be argued that the one is not effective without the other, i.e. they are mutually dependent. 50While procedural public values cannot exist in themselves (i.e.substantive aspects are necessary to shape the procedural values), respect for substantive values would be difficult to achieve without any procedural elements.
In light of the above considerations, the following working definition of 'public values' will be adopted for the purposes of the present analysis: 'Public values are guiding principles or guidelines, which should -from a perspective of societal morality and in the interest of the public -be taken into consideration in political and legal decision-making.' 51

Water-specific public values
Given this general concept of public values, how can we define which public values are specifically related to water?There is no question about water being essential for sustaining life on Earth. 52In this respect, Thomson states that 'water is inherently public, and governments have a continuing obligation to ensure its effective management for overall societal well-being, including both environmental protection and essential human consumptive needs.' 53 Here, Thomson, arguably, refers to public virtues, and more in particular to 'public water virtues' .Water, in this view, is essential in any attempt to achieve at least some degree of environmental protection and human health.Both virtues are inherently interrelated, as the former cannot, at least not in the long term, be guaranteed without the latter.These virtues subsequently underlie concrete goals worth pursuing for the sake of overall societal well-being. 54Public values, in turn, play an important role as framework guidelines for making legislative and policy decisions on defining these goals and the pursuit thereof.
In the literature on water law certain public values are mentioned.Often-cited public water values are, for instance, sufficiency, safety, quality, accessibility, affordability, and aesthetic beauty. 55Others mention the continuity and quality of water services, and user and consumer protection as public values the government should safeguard, either directly or indirectly. 56Moreover, also the precautionary principle, the principle of tackling environmental degradation at the source, and the principle that the costs of protective measures should be recovered from those who pollute or make a profit out of it are among the values most often mentioned. 57ndeed, one could distinguish many public values related to water.Among these values, hierarchal links may and often do exist.For instance, water being affordable is, at least partly, instrumental to it being accessible.The three legal principles mentioned above are also instrumental to, for instance, achieving good water quality.And water being of good quality is in turn instrumental to the 'water virtues' of both human health and environmental protection.Although there is no room in this article to untangle the web of relationships between all public values related to water and to assign them to different 'classes' of public water values, it is assumed that they are all in some way directed at the overarching objective of reaching overall societal well-being.Instead of unravelling this web, the Figures 1 (general) and 2 (water-specific) below provide general insight into the relations as described above (especially see the two 'layers' at the top).
The fact that one value is instrumental to another does not mean that it is no longer a public value.At some point down the line of instrumentality, 58 some things, however, lose their property of being a public value and have simply become rules of conduct that exist for the benefit of some public value, given that they no longer meet the criteria of Bozeman's definition.Another reason could be that such rules are no longer considered 'values' , but norms.An example would be the legal prohibition to discharge substances into the surface water without a permit.Although this could be considered a rule that the public in general would agree with and that is the outcome of the public's involvement through a legislative process at various levels of water law, it is not a 'guiding principle' that governments should adhere to and neither is it what would normally be considered a 'value' (see the bottom 'layer' in Figures 1 and 2).
53 See Thomson 2011, supra note 32, p. 19 (emphasis added).54 These goals may range from highly general aims (for instance pursuing a high level of environmental protection) to very concrete and specific short-term policy objectives (for instance pursuing a specific water quality standard within a certain timeframe).Van  57 Almost everyone finds these principles of value: society as a whole (often through politics) wants to have a say in determining the outcome in terms of specific rights and rules of conduct, and governments use them as guiding principles for their law-making and water policy.58 When moving away from the overarching value of overall societal well-being.

Figure 1
Figure 2 The analysis in Section 3 will only look at public values and is concerned with the rules of conduct only to the extent to which they serve to discover the underlying public values.In addition, this article focuses at public values in water law.This does, however, not mean that values that are incorporated in water law, but are also generally applicable to other policy areas, will be disregarded.For instance, broadly applicable values, such as the precautionary principle and efficiency, are discussed.However, certain procedural public values such as subsidiarity and proportionality are not.

Identifying public water values: methodology
Until now, literature has not provided for an extensive and integral assessment of public values in water law at the international, European, sub-regional and domestic level. 59For this reason, the main purpose of this contribution is to identify these public values based on a comparative assessment of the levels mentioned.These public values -as guiding principles for governments to base their laws and policies on -can be explicitly or implicitly embedded in public law (international treaties, primary/secondary EU legislation, domestic constitutions, or Acts of Parliament). 60Hence, the methodology used is an in-depth analysis of a selection of relevant legal provisions with regard to each level of water law.As indicated, in this search for public values, not only the explicitly mentioned public values are to be identified, but also those that are at the basis of concrete rules of conduct.These values are to be untangled from these concrete rules, as indicated in explanatory notes and documents.Every candidate public value has been tested on whether 1) it fits the working definition of this paper and hence if it is truly a public value, and 2) if it sufficiently relates to 'water' to be called a 'public water value' .Next, the water-specific public values incorporated in the law at the different levels have been compared across the scale in order to assess whether and to what extent there is substantive fragmentation in terms of the protection of public values. 61This involves finding corresponding values at the various levels in order to conclude if a level shows omissions and/or differences compared to other levels with regard to protecting specific public values.It should be noted that it is important at this point to check if the same public value might be protected under a different name at the various levels, or if a public value is protected without it being mentioned (values can be 'hidden' in the law), or if values that are instrumental to another value are explicitly protected.

Public values at different levels of water law
This section traces various public values incorporated at different levels of water law.The public values will be identified through a cross-scale comparison aiming to single out corresponding values as well as differences across the four levels of water law discussed in this article.

Relevant legal instruments
The two dimensions of water law and governance addressed in this paper are the social and the environmental ones.While at the international level these can be clearly distinguished, 62 as indicated above, this is less clearly so at the other levels.This section introduces the legal instruments that address these dimensions at the various levels, which form the basis of the cross-scale comparison.
As explained above, the social dimension of water law focuses on the human right to water and development.The most relevant instruments at the international level 63 are the following: General Comment 15 of the Committee on Economic, Social and Cultural Rights (CESCR) on the human right to water, 64 General Assembly resolution on the human right to water and sanitation, 65 and the United Nations Millennium Declaration 66 as well as the documents resulting from the conferences leading up to 67 and following 68 the adoption of these Millennium Development Goals (MDGs).2003 is an important benchmark for this dimension, being the year that the CESCR adopted its General Comment 15 in which the human right to water as an autonomous right was established. 69he environmental dimension of water law and governance at the international level includes the following main instruments: 70 Convention on the Law of the Non-Navigational Uses of International Watercourses (1997 Convention) 71 (although not in force yet), the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Helsinki Convention), 72 its two Protocols (Helsinki Protocol I 73 and Helsinki Protocol II), 74 and the 2008 International Law Commission (ILC) Draft Articles on the Law of Transboundary Aquifers (which to a great extent follow the 1997 UN Watercourse Convention). 75t the European level, the following instruments can be highlighted.Before the entry into force of the European Water Framework Directive in the year 2000, European water law was a patchwork of different types of directives, with little mutual coherence.For each type of water usage, a specific directive existed.The WFD marked a great change in this sectoral approach by integrating many directives and amending others, thus aiming at a more transparent, effective and coherent European water law. 76By the end of 2013, only a small number of European water directives remain. 77uropean water law is situated mainly in the environmental dimension. 78Besides the specific directives addressing water-related values, the Treaty on the Functioning of the European Union (TFEU), which enshrines important public values, should also be mentioned.Within this dimension, a distinction can be made between water quality, water safety 79 and water quantity issues. 80By far most of the European directives deal with water quality issues. 81The WFD itself forms the core of current European water quality law.The Groundwater Directive 82 and the Directive on Priority Substances 83 replace former directives 84 and both now function as daughter directives to the WFD.These two Directives contain specific quality standards to further elaborate the environmental objectives of the WFD for groundwater and surface water respectively.In addition to these directives, European water quality law also encompasses the Drinking Water Directive (DWD), 85 the Bathing Water Directive, 86 the Nitrates Directive 87 and an Urban Waste Water Directive. 88In contrast to the multitude of directives regarding water quality law, the protection against flooding is regulated at the European level in only one directive: the Floods Directive (FD). 89Although it is one of the aims of the WFD to integrate all aspects of water management, water quantity is barely present as a separate element in European law. 90he 'watercourse' 91 is generally considered the basic or natural unit of water governance.Often, these watercourses are international, for which reason law and governance at the sub-regional level are of utmost importance. 92Admittedly, this perspective on watercourses primarily focuses on water as an instance, be illustrated by the fact that all the relevant legislation at the European level is drafted and enforced by the Directorate-General for the Environment of the European Commission.Furthermore, this evidently follows from the contents of the legislation.In addition, it should be noted that Consideration 16 of the WFD's Preamble indicates that the Directive should provide a basis for further integration with the other two dimensions covered in this article (specifically mentioning the policy areas of energy, transport, agriculture, fisheries, regional policy and tourism).Consideration 17 mentions another link with the economic dimension by stating that protection of water status will provide economic benefits by contributing towards the protection of fish populations.79 Water safety is approached as the protection against floods.That this is a distinctive aspect of water law can be seen in Consideration 4  of the Preamble of the Floods Directive.80 Water quantity is approached as the protection against water scarcity and droughts.See  environmental unit, but traces of the other dimensions of water can also be detected at this level, too.In the Danube River Basin there are two main treaties regulating the 'use' of the Danube: the Danube River Protection Convention (DRPC) 93 and the Danube Navigation Convention (DNC). 94Here the focus will be placed on the former, and the latter will not be addressed due to its very specific purpose to regulate the navigational use of the river.The DRPC established the Danube Commission 95 in order to assist states in implementing the Convention (and later on to provide a platform for the implementation of the EU Water Framework Directive). 96ith the entry into force of the Water Act 97 (WA) in 2009 and the Drinking Water Act (DWA) 98 in 2011, Dutch water law and the organization of water management in the Netherlands underwent major changes. 99In recent Dutch water management a rough distinction is made between the integral management of water systems (quality; ecology; quantity) and the more fragmented management of the 'water chain' (drinking water supply; sewerage; waste-water purification).This distinction is -although not that explicitly -also recognizable in the law.The WA integrates previously sectoral water legislation on, inter alia, water quality, water safety, waste-water purification, fresh water supply and ecology into one act.It, moreover, explicitly links water management with other policy domains, such as environmental protection and spatial planning. 100Further legal integration of these and other policy domains lies ahead. 101The DWA provides modernized provisions on the production and supply of drinking water by drinking water companies. 102The Environmental Protection Act (EPA) enshrines provisions on the intake and transport of urban waste-water (sewerage). 103This 'body' of Dutch water law is mainly based on two general provisions of the Dutch Constitution (Articles 21 and 22) and implements European water law into the Dutch legal system.This table is the result of an extensive multi-level analysis by the authors.It would not fit within the scope of this article to integrally and extensively discuss the outcomes of this analysis here.Hence, a more extensive report of the analysis can be found at the website of the Utrecht Centre for Water, Oceans and Sustainability Law. 104Instead, a representative selection of both substantive and procedural public water values will be elaborated in further detail below.This selection follows the sequence of the values listed in the table above.First, the procedural values of transparency, participation and accountability will be discussed.Next, a selection of six substantive values pertaining to water management will be elaborated: prevention/precaution, sustainability, integrality, the river basin approach, the polluter pays/ cost recovery principle, and the value of equality.The section concludes by discussing several values pertaining to drinking water that are also closely related to the human right to water.

Transparency
At the international level, the legal documents relating to the social dimension of water law as well as to its environmental dimension include rules enhancing the transparency of decision-making.General Comment 15 explicitly mentions 'the right to seek, receive and impart information concerning water issues' ,105 which reflects the need for 'information accessibility' . 106Related to information accessibility, although at a different level, is the need to exchange technical and scientific information relating to water law, policy and management among states. 107This would enable capacity building and technical transfer across boundaries, also making information accessibility within the national boundaries more effective.These two 'rules' could be translated as the public value of transparency.Transparency is important both in the inter-state context and, in relation to individuals, also in the environmental dimension at the international level.As far as the former is concerned, the 1997 Convention expects states to regularly exchange data 108 and rely on notification-consultation procedures. 109With regard to individuals the Helsinki Convention and its Protocol I impose the obligation upon states to provide the public with access to information 110 and to raise awareness (with regard to water rights). 111t the EU level both the WFD and the FD enshrine rules that aim to ensure transparency. 112Article 15 of the WFD, for instance, obliges Member States to inform the European Commission of the goals they intend to achieve regarding the desired water quality, and of the means they intend to use in order to achieve these goals as well as the methods used to monitor their progress and the results of this monitoring. 113Article 14 obliges the Member States to also inform the public, since it is instrumental to the value of participation. 114According to the Preamble to the WFD, transparency is a necessity for the success of the WFD and of EU water policy in general. 115lso in water law at the sub-regional level, the procedural public value of transparency is clearly embedded.In the Convention on the Protection of the Danube River Basin Articles 12 and 14 enshrine norms with regard to this value.Article 12 of the Convention lays down rules on the exchange of information among the contracting parties, as Article 14 holds rules on providing information to the public.
In the Netherlands, first of all Article 110 of the Dutch Constitution explicitly establishes a general right of public access to information.In relation to water-specific regulations, the objectives of the WA are at the basis of government responsibilities in Dutch water management.Regarding all responsibilities, strategic policy goals and operational provisions should for successive periods of six years be laid down in so-called water plans and management plans. 116These plans, inter alia, aim at informing the public in order to ensure transparency in water management.Also the EPA enshrines transparent decisionmaking.More concretely, for instance, every two years an official report is to be published on 'the state of affairs' of Dutch waste-water management. 117Moreover, the municipalities are obliged to lay down their policy on sewerage in so-called sewerage plans. 118Other authorities have to be actively involved in the planning process.Sewerage plans must be sent to all authorities involved in the planning process, as well as to the Minister, and must also be published in a municipal newspaper. 119Finally, transparency is one of the core values underlying the DWA. 120The DWA imposes obligations in this regard on water companies, which must secure the connection of consumers to the supply network and the actual supply under reasonable, transparent and non-discriminatory conditions. 121

At the international level participation is secured in various ways.Pursuant to the General Comment individuals should also be able to influence the decision-making processes relating to their human right to water, 122 i.e. they should be able to participate.Similarly to transparency, respect for participation is ensured for states and individuals at the international level concerning the environmental dimension of water.The 1997 Convention lays down the principle of equitable and reasonable participation of state parties, 123 the obligation to cooperate and establish joint mechanisms. 124As to the relationship with individuals, the Helsinki Protocol I lays down that '[a]ccess to information and public participation in decision-making concerning water and health are needed, inter alia, in order to enhance the quality and the implementation of the decisions, to build public awareness of issues, to give the public the opportunity to express its concerns and to enable public authorities to take due account of such concerns.' 125 Moreover, the Protocol also requires the involvement of locals 126 and the creation of a platform for parties, where 'the public, private and voluntary sectors can make its contribution to improving water management for the purpose of preventing, controlling and reducing water-related disease.' 127 At the EU level, participation is also an explicitly mentioned value that found its way into the WFD as well as the FD.Article 14 of the WFD, for instance, obliges all Member States to encourage the active involvement of all interested parties in the implementation of the WFD.To this end, they shall inform the public of the procedure regarding the implementation and supply them with all the necessary substantive information.Member States are also obliged to offer the public ample opportunity to comment on their plans regarding this implementation.Article 10 of the FD includes a similar, albeit less detailed, obligation.According to the Preamble to the WFD, its success is dependent on this consultation and involvement of the public. 128lso at the sub-regional level, the public value of participation is clearly embedded, as the contracting parties are expected to 'provide for coordinated or joint communication, warning and alarm systems in the basin-wide context' 129 and 'shall provide mutual assistance upon the request of other Contracting Parties' . 130n the Netherlands, only the WA and the EPA include rules that can be related to participation.The WA contains provisions concerning cooperation with and consultation of other authorities, and also provisions on the participation of the public in, for instance, decision-making procedures concerning water plans and management plans.These should be interpreted as an invitation to all stakeholders (both public and private) to participate in the policy-making process, emphasizing the urge of cooperation and coordination in Dutch water management (which also ensures coherency and integrality).The WA and EPA both emphasize the need for cooperation between public actors in order to achieve higher levels of efficiency without a decrease in quality. 131The EPA has not, however, enshrined further provisions requiring the authorities to ensure public participation in the planning process; apparently public participation is seen as a value of minor importance in relation to policy-making concerning sewerage management.Like the EPA in relation to waste-water management, the DWA does not hold any provisions concerning public participation in policy and decision-making concerning the production, transport and distribution of drinking water.

Accountability
The last procedural value to be discussed here is accountability, including access to justice.Accountability can be ensured in various manners.At the international level, the General Comment expects states to establish monitoring mechanisms and impose penalties '[w]here water services (…) are operated or controlled by third parties' in order to ensure the protection of water rights. 132A closely related aspect is the need to set up 'remedies and recourse procedures' 133 and to ensure that '[a]ny persons or groups who have been denied their right to water should have access to effective judicial or other appropriate remedies at both national and international levels' . 134In the environmental dimension of international water law ensuring accountability has been foreseen through, again, two types of norms: one focusing on interstate relations and the other on individual-state relations.The first type of norms is somewhat vaguely formulated and includes the following: states are recommended to establish joint actions, 135 they are under the obligation to monitor the conditions of transboundary waters 136 and to carry out environment impact assessments. 137Concerning the second type of norms, the Helsinki Protocol II requires states to establish civil liability mechanisms for damages 'caused by the transboundary effects of industrial accidents on transboundary waters.' 138 Last but not least, the 1997 Convention places an obligation on states to ensure cross-border access to justice without discrimination in case of transboundary harm. 139lthough accountability is not mentioned as a separate value in any European water directive, it is definitely implicitly present in the system of European law.The WFD contains very specific obligations (most importantly in Article 4).By European law, Member States are bound to meet these obligations and they can be held accountable if these obligations are not met. 140In this sense, the aforementioned value of transparency can be seen as instrumental to this value, since it provides citizens and the European Commission with ample information to hold Member States accountable if the obligations are not met.It should be noted however, that the WFD does leave plenty of room for Member States to justify not fully meeting these obligations within the set deadline.
In the Danube River Basin certain obligations aim to advance accountability in different ways.Among these provisions the following can be highlighted: states 'shall report to the International Commission on basic issues required for the Commission to comply with its tasks' , 141 'shall monitor the progress made in the implementation of the joint action programmes by establishing periodical progress reviews' , 142 and 'shall cooperate in the field of monitoring and assessment' . 143As mentioned above, at this level there is a central organisation, which also gained in importance with regard to safeguarding accountability.
Finally, in the Netherlands the procedural public value of accountability is clearly embedded in legislation in the field of public health and environmental protection.The Dutch Constitution breathes a strong moral and general sense of liberty and equality, and it generally entitles the public to judicial review of government decisions. 144Moreover, as mentioned before, water authorities according to the WA need to adopt water plans and management plans. 145These plans, like the sewerage plans, function as accountability mechanisms towards other authorities and also towards the public. 146Accountability is also one of the core values underlying the DWA.The drinking water companies, on a yearly basis, must report on their activities to the Minister.Subsequently, the Minister, also on a yearly basis, must report on the quality of the Dutch drinking water supply as such to both Houses of the States General, as well as to the public. 147

Prevention/precaution
Although strictly speaking, prevention and precaution are not exactly the same thing, the two values are very closely related. 148They both refer to a future occurrence of environmental damage and they both aim to avoid this occurrence.For instance, Article 3(2)(e) of the Danube River Protection Convention speaks of the 'precautionary prevention' of accidents.Given their close relationship, both values are discussed here simultaneously as core values in water law.
At the international level, the precautionary principle is laid down in the Helsinki Convention. 149t the EU level, Articles 191( 2) and (3) of the Treaty on the Functioning of the European Union state that environmental (and hence water) policy should be of a precautionary and preventive nature.In secondary EU law, the Water Framework Directive 150 and the Drinking Water Directive 151 mention both values, whereas the Floods Directive only mentions prevention. 152In the Danube River Basin the principles of prevention and precaution can be traced in various rules, too, which 'constitute a basis for all measures aiming at the protection of the Danube River and of the waters within its catchment area.' 153 At the domestic level, prevention and, implicitly, precaution 154 (addressing both flooding, water nuisance and drought, and deterioration of water quality and ecology) can be discovered as values in Article 2.1 of the Water Act.Drinking water companies, moreover, have a legal duty of care to prevent drinking water sources from being polluted. 155On the basis of the methodology presented above, at all institutional levels, prevention/precaution could be considered a substantive public water value.

Sustainability
Also sustainability is often mentioned as a core public value in water and environmental law. 156At the international level, the value of sustainability is explicitly mentioned, for instance in General Comment 15 and the 1997 Convention. 157Also in secondary EU law, this value is mentioned in the Water Framework Directive,158 the Drinking Water Directive 159 and the Floods Directive. 160The same counts for the subregional level, as in the Danube River Basin, one of the objectives enshrined in Article 2(1) of the DRPC is to achieve 'the goals of a sustainable and equitable water management' .
At the domestic level, the value of sustainability is only explicitly mentioned in relation to drinking water: Article 2(1) and ( 2) of the DWA refer to the sustainable security and organization of the public drinking water supply as an 'imperative reason of overriding public interest' .Although it was deliberately decided not to explicitly incorporate principles in the WA, 161 the principle of sustainability may implicitly be found at the roots of the objectives of the WA as laid down in Article 2.1, as there is a close relation between the principle of sustainability and those of prevention and precaution.In conclusion, sustainability is another substantive public value that is clearly embedded in water law at the different institutional levels.

Integrality
Integrated water resource management proves to be another value in water law and governance. 162lthough an important value, it found its way into legislation at the international level only in the Helsinki Protocol I; 163 earlier conventions do not mention this value.
At the EU level this value is omni-present: it is explicitly laid down in the WFD as an underlying public value. 164It is indicated that water should be managed integrally, covering all its components and usages.Moreover, the WFD also strives to expand this approach to all policy areas dealing with water. 165lso, the Floods Directive is based on the principle of integrality. 166Parallel to the WFD and the FD, the DWD also recognizes the value of an integrated approach to water policy. 167lthough the DRPC does not explicitly mention the idea of integrated management, as an effect of its role in coordinating the implementation of the WFD, this value also entered this level of water law.In particular, the International Commission for the Protection of the Danube River (ICPDR) explains that '[t]he WFD brings major changes in water management practices.Most importantly, it introduces the river basin approach for the development of integrated and coordinated river basin management plans for all European river systems' . 168Accordingly, the Commission tries to incorporate this value in its working method.
At the domestic level the objectives of the WA as enshrined in Article 2.1 of the WA clearly reflect the need for integrated water management.These objectives are a) to prevent and, where necessary, to limit flooding, water nuisance and water shortage, while simultaneously b) protecting and improving the chemical and ecological status of water systems, and c) allowing water systems to fulfil their societal functions.As there is no formal legal order of objectives, these should explicitly be executed in an integral and conjunctive way. 169Coherency and integrality, in turn, are claimed to be a necessity for -or to be instrumental to -effectiveness and efficiency in Dutch water management. 170

River basin approach
The next important value is the so-called river basin approach, which is closely related to the previous value of integrated water resources management. 171This means that the river basin is chosen as the most appropriate unit to manage water, reflecting the insight that water does not follow national borders.This value relies on the idea that a river basin constitutes a coherent unit, and thus the water in its catchment area should be managed based on this unit.
At the international level, this approach is implicitly present in, for instance, the 1992 Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Helsinki Convention). 172U water law is explicitly based on this approach. 173This approach is one of the most important guidelines for water policy in the Member States.The river basin approach requires cooperation between Member States, 174 and establishes common definitions, 175 whilst taking diversity between Member States into account. 176This approach can also be discovered in the rule that cross-border pollution should be controlled 177 as well as in the principle of equitable use. 178Implicitly, the FD is also based on the river basin approach; this becomes clear by the many references to the WFD and by the multitude of occurrences of the river basin as the unit of water management.
While the DRPC does not explicitly mention the value of a river basin approach, the very existence of this level of water law and governance relies on this value.The Convention aims to adopt policies that take into account the whole basin.
Finally, the river basin approach is fully incorporated in Dutch water law, thus implementing the EU WFD. 179This approach has been explicitly enshrined in Article 1.2 of the WA.Four river basin districts -those of the Ems, the Meuse, the Rhine and the Scheldt -are situated on the Dutch territory.Moreover, the WA adopts an integrated water system approach, 180 which stipulates that bodies of surface water and groundwater, as well as storage areas, flood defence structures and ancillary structures should be managed integrally.The management of one or more individual water systems or parts thereof is directed at achieving the objectives referred to in Article 2.1 of the WA, as discussed above. 181

Polluter pays/cost recovery
Another important public value is the polluter pays principle, or -more generally -the cost recovery principle.This value is present at each level of water law and governance addressed in this article.The Helsinki Convention lays down the polluter pays principle in Article 2(5)(b). 182t the EU level, this public value is laid down in Article 191 (2) stating that the costs of protective measures should be recovered from those who pollute or profit. 183The WFD also enshrines this value specifically in relation to water; the principle that the polluter should pay is explicitly mentioned. 184n the Danube River Basin the polluter pays principle is closely linked to prevention and precaution.These values can be traced in various rules, which 'constitute a basis for all measures aiming at the protection of the Danube River and of the waters within its catchment area.' 185 For instance, the polluter pays principle has been explicitly enshrined in Article 2(4) of the Danube Convention.
At the domestic level, Chapter 7 of the WA on taxation stipulates that the party polluting the water should (at least to some extent) bear the costs of measures to be taken to protect and improve the chemical or ecological status of water systems, which can be translated as the polluter pays principle.Also for other water services, Dutch water authorities are allowed to impose taxes, based on the Dutch Water Authorities Act. 186This reflects the user pays principle or the beneficiary principle.Similar provisions can be found in the legislation on sewerage management and drinking water.The cost recovery principle ('user pays') is clearly reflected in the law concerning sewerage management, as Article 228a of the Act on Municipalities establishes a taxation competence for sewerage services.The user pays principle is embedded in Article 11 of the DWA.Drinking water rates should be fair, transparent and non-discriminatory, and moreover these may only aim at the recovery of costs, not at any kind of profit.

Equality
Last but not least, equality is an important value when it comes to water management.At the international level, several documents stipulate that a conflict between water uses should be resolved 'with special regard being given to the requirements of vital human needs.' 187 In addition, the Preamble of the 1997 Convention also considers 'the special situation and needs of developing countries' -i.e. the special and vulnerable position of those living in these countries.Helsinki Protocol I pays special attention to 'those who suffer a disadvantage or social exclusion' 188 and to 'the protection of people who are particularly vulnerable to water-related disease' . 189These provisions reflect the idea of intra-generational equality.In addition, the Helsinki Convention and its Protocol I also refer to inter-generational equality. 190he EU level also pays some attention to equality.For instance, Consideration 1 of the WFD starts with the recognition that water is a public good and points to the notion of inter-generational equality. 191lthough in EU law in general, solidarity between Member States is a core principle, 192 this has only modestly been elaborated in EU water law.The FD recognizes that there should be fair sharing of responsibilities and that the interests of other states should be taken into account when taking measures. 193he WFD, however, the most important of all European water directives, has failed to implement the notion of river basin management in such a way that the possibility to utilize rivers is distributed in an equitable way amongst riparian states, causing evident inequality between Member States. 194n the Danube River Basin there is attention to future generations as well, 195 when it comes to conservation of water, in particular the protection of drinking water supplies.No specific mention is made of intra-generational equality -probably due to the environmental (and not human rights) focus of the Convention.
In the Netherlands, intra-generational equality can be found at the basis of the WA. 196This value is, for instance, reflected in the so-called 'priority of needs' ('verdringingsreeks'; Article 2.9 of the WA), as in times of water shortage the remaining water will be distributed in an equitable way, as legally determined in the Water Decree.There is no explicit reference to inter-generational equality in Dutch water management law, but water policy more and more focusses on the interests of future generations, or at least on looking further into the future. 197Also the DWA breathes a clear scent of intra-generational equality, as fairness, non-discrimination, and consumer protection are at its deepest roots.One could argue moreover that also inter-generational equality is a value underlying the Drinking Water Act, as securing the sustainability of the public drinking water supply also takes place in the interest of future generations.This is endorsed by the fact that drinking water companies in their so-called drinking water supply plans must pay attention to, inter alia, the needs of future generations, or at least 'future drinking water needs' . 198

Public water values pertaining to drinking water/the human right to water
The public values relating to drinking water that are most frequently mentioned are safety, affordability, sufficiency, adequacy, accessibility, continuity, fair pricing and rational use.These values closely relate to the human right to water.It has proved difficult to discuss these values separately since they are so closely related and often instrumental to one another.Hence, they are discussed simultaneously below.
At the international level clear guidelines have been set as far as the human right to water is concerned.As the CESCR indicated, everyone has the right to sufficient, safe and affordable drinking water. 199In addition, General Comment 15 lists among its core obligations, which, unlike other economic, social and cultural rights, require immediate action, that '[t]he elements of the right to water must be adequate for human dignity, life and health' . 200In addition, the priority of uses is also established in General Comment 15, which means according to the CESCR that '[t]he human right to water entitles everyone to sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses.' 201 At the EU level, the Drinking Water Directive (DWD) addresses the human rights dimension of water.It explicitly mentions the need for wholesome and clean drinking water. 202Remarkably, sufficiency of drinking water is not mentioned as an underlying public value in this Directive, nor can it implicitly be discovered by analysing the more specific rules of the Directive. 203At the sub-regional level of the Danube River Basin, there is no clear trace of underlying public water values pertaining to drinking water.
In the Netherlands, especially in comparison to the relevant provisions at the other institutional levels, the human right to water is exhaustively elaborated and embedded in legislation, mainly in the DWA.Some aspects of the Dutch drinking water law have already been discussed above; these will not be discussed again.First of all, from a public health point of view, there is strong emphasis on the need to ensure sufficient drinking water of a high quality. 204Moreover, no-one should be deprived from drinking water under normal circumstances (accessibility and continuity). 205As mentioned above, drinking water should be affordable, and pricing should take place in a fair, reasonable, non-discriminatory and transparent manner, while drinking water companies are legally encouraged to execute their tasks and organize their services as efficiently as possible. 206One last remarkable aspect of the DWA to be mentioned here is that the drinking water companies not only have obligations regarding the interests of their consumers; they must also endeavour to raise public awareness and to encourage rational use. 207This means consumers values.The actual protection depends on many other factors.It is beyond the scope of this article to delve deeper into these factors.
It should also be noted that exploring only one domestic, one regional and also one sub-regional level for that matter makes it difficult to draw general conclusions regarding the substantive fragmentation of water law as far as public values are concerned.This analysis can only serve as an example and does not claim much predictive value for analyses of other domestic or (sub-)regional legislative systems.As the analysis underlying this article shows no particularly strong substantive fragmentation, it might be argued that there are no serious social and environmental problems as mentioned in Section 2.1 at the levels studied.But, of course, if India had been studied rather than the Netherlands, for example, the results presented above may very well have been quite different and might have led to other conclusions regarding the severity of the negative effects mentioned.
Hence, to conclude this analysis, it can be said that this article provides some interesting observations regarding the differences and similarities in the theoretical protection of public water values at the levels studied.However, this is only the starting point for further analysis.Not only is more research needed regarding the substantive differences and similarities in the protection of public values in general, also a broader range of 'lower' levels should be studied in order to draw stronger conclusions regarding substantive fragmentation and its effects.¶ The term 'public values' incorporates two aspects: what is public and what are values?First, what makes a value public?In this regard Bozeman's definition deserves particular attention.Bozeman aims to define the 'publicness' of values as follows: Rijswick also argued that '[h]ealth and well-being of human have been the motive for environmental and water protection for a long time and it is for the same reason why economic development often prevails over nature protection.The past decades have seen more attention being devoted to nature as an autonomous value worthy of protection.'SeeVan Rijswick 2008, supra note 1, p. 13. 55 See, for instance, General Comment 15, supra note 12. 56 See De Bruijn & Dicke 2006, supra note 38, p. 719.
76 See Consideration 17 of the WFD's Preamble.77 The Shellfish Water Directive (Directive 2006/113/EC of the European Parliament and of the Council of 12 December 2006 on the quality required of shellfish waters, OJ L 376, 27.12.2006,pp.14-20) and the Freshwater Fish Directive (Directive 2006/44/EC of the European Parliament and of the Council of 6 September 2006 on the quality of fresh waters needing protection or improvement in order to support fish life, OJ L 264, 25.9.2006, pp.20-31) were repealed by the end of 2013.78 This can, for below.81 See Van Kempen 2012, supra note 1, p. 22. 82 Directive 2006/118/EC of the European Parliament and of the Council of 12 December 2006 on the protection of groundwater against pollution and deterioration, OJ L 372, 27.12.2006,pp.19-31.83 Directive 2008/105/EC of the European Parliament and of the Council of 16 December 2008 on environmental quality standards in the field of water policy, OJ L 348, 24.12.2008,pp.84-97.84 Directives 80/68/EEC, 76/464/EEC, 82/176/EEC, 83/513/EEC, 84/156/EEC, 84/491/EEC and 86/280/EEC.85 Council Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption, OJ L 330, 5.12.1998, pp.32-54.86 Directive 2006/7/EC of the European Parliament and of the Council of 15 February 2006 concerning the management of bathing water quality, OJ L 064, 04.03.2006, pp.37-51.87 Council Directive 91/676/EEC of 12 December 1991 concerning the protection of waters against pollution caused by nitrates from agricultural sources, OJ L 375, 31/12/1991, pp.1-8.88 Council Directive 91/271/EEC of 21 May 1991 concerning urban waste-water treatment, OJ L 135, 30.5.1991, pp.40-52.In addition to this, there are also other European directives that deal with water quality in a more indirect way but that are primarily meant to regulate other policy areas.The most prominent examples are the Birds Directive, the Habitats Directive and the Directive on Industrial Emissions.Council Directive 79/409/EEC of 2 April 1979 on the conservation of wild birds, OJ L 103, 25.04.1979,pp.1-18; Council Directive 92/43/ EEC of 21 May 1992 on the conservation of natural habitats and of wild fauna and flora, OJ L 206, 22.07.1992,pp.7-50; Directive 2010/75/ EU of the European Parliament and of the Council of 24 November 2010 on industrial emissions, OJ L 334, 17.12.2010,pp.17-119 (the successor of the IPPC Directive).89 Directive 2007/60/EC of the European Parliament and of the Council of 23 October 2007 on the assessment and management of flood risks, OJ L 288, 06.11.2007, pp.27-34.Consideration 4 of the Preamble of the Floods Directive clearly states that flood protection is a separate dimension of European water law in addition to water quality law.90 The WFD's daughter directives will not be further analysed since they do not protect public values other than those already protected in the WFD.The other water quality directives will not be covered either due to space constraints.An exception is made for the Drinking Water Directive, because an analysis of this Directive allows a better comparison with the other levels.
91 For a definition of 'watercourse' seeArt.2(a)of the 1997 UN Convention.Pursuant to this Article, a 'watercourse' is 'a system of surface waters and groundwaters constituting by virtue of their physical relationship a unitary whole and normally flowing into a common terminus.'92 See M.A. Giordano & A.T.
