Landscape irrigation often presents a specific challenge when water needs to travel in a distinct linear path along a defined edge. This is where the side strip sprinkler pattern becomes essential, offering a targeted solution for narrow areas that standard circular coverage cannot efficiently address.
Understanding the Side Strip Pattern
The side strip pattern is a specialized configuration designed to propel water in a concentrated arc that covers a long, narrow zone. Unlike a full-circle or quarter-circle spray that disperses water broadly in a fan or pie slice, this pattern focuses the throw to the sides rather than the front. This creates a consistent wetting line along the edge of the spray zone, making it ideal for hedges, narrow medians, or the borders of large lawns.
Application in Landscape Design
Professional landscapers and irrigation designers utilize this pattern to solve the problem of the "edge effect." When you place a standard rotary head in a flower bed, much of the water lands on the concrete or the interior of the garden, wasting resources and creating uneven moisture. By aligning spray heads specifically for a side strip effect, water is directed precisely where it is needed most—along the linear boundary.
Optimal Placement and Spacing
To ensure seamless coverage without dry gaps, the placement of these heads requires careful calculation. The throw distance must match the spacing between heads. If the heads are too far apart, the landscape will develop a checkerboard pattern of wet and dry spots. Conversely, if they are too close, excessive overlap occurs, leading to wasted water and potential runoff.

Technical Specifications and Nozzle Choice
The performance of a side strip pattern is largely determined by the nozzle installed within the housing. These nozzles are precision components that dictate the arc of travel and the degree of throw. Selecting the correct nozzle is not merely a matter of preference; it is a critical step in hydraulic calculation. Using the wrong nozzle can result in under-application or over-spray onto unwanted surfaces.
Pressure Requirements and Performance
Maintaining appropriate water pressure is crucial for the efficacy of this pattern. These systems generally require a minimum pressure to achieve the necessary distance without breaking the stream into droplets. Too little pressure results in a weak, inconsistent spray, while excessive pressure can cause misting, which evaporates before reaching the roots. Professionals often install pressure regulating valves to ensure the system operates within the optimal PSI range.
Maintenance Considerations
Because the nozzles for this pattern are often smaller and more intricate, they are susceptible to clogging from sediment or mineral buildup. Regular maintenance is required to keep the water flow consistent. Simply removing the nozzle and rinsing the screen filter can prevent a multitude of irrigation issues. Additionally, physical damage from lawn mowers or string trimmers can alter the trajectory of the spray, requiring realignment during routine seasonal checks.
