<br />Methodoloav <br /> <br />Perform a visual inspection: A visual inspection of all sprinkler heads within <br />functioning zones was performed during operation to 1) identify head type such as rotor, <br />fixed, or drip; 2) list damaged, misaligned, or other malfunctioning heads; 3) note any <br />other issues that negatively impact efficiency or creates waste. Control systems, such as <br />timer clocks, were also inspected. The homeowner/property manager is always <br />encouraged to join the auditor on the visual inspection. <br /> <br />Appendix A: Irrigation Glossary <br />Appendix B: Common Problems <br /> <br />Perform Catch Cup Tests: Catch cup tests were performed on designated zones. A <br />catch cup test utilizes calibrated cups (designed by the Bureau of Reclamation), set in a <br />grid pattern on the landscape to collect water from an irrigation system. The amount of <br />water collected can be used to determine distribution uniformity and precipitation rates. <br />The zones tested are intended to serve as a general representation of the irrigation system <br />as a whole. <br /> <br /> <br />Distribution uniformity (DU) is a measurement of an irrigation system's ability to apply <br />water uniformly over the surface of a landscape and directly influences the amount of <br />water required to keep the landscape green. If the amount of water put out by an <br />irrigation system is not completely uniform, some parts of the landscape will receive <br />more water than others. Efficient systems operate at a DU of 70% or greater and minor <br />adjustments to most systems can significantly improve the DU. <br /> <br />Precipitation rate (PR) is the amount of water emitted from an irrigation system measured <br />in inches of water per hour. Different head types have different precipitation rates. The <br />precipitation rate determines how long you need to run a sprinl<ler system. A spray head <br />usually emits 1-2' , (on average 1.4") of water per hour, while a rotor head emits .5 - 1" <br />(on average .9") of water per hour. Precipitation rates for each type and model of head <br />will vary depending on the manufacturer. <br /> <br />Take Pressure Readings: Utilizing a pressure gauge along with the proper attachments, <br />pressure readings were tal<en on spray zones as well as rotor zones. When reading the <br />pressure for a spray zone, the pressure gauge is screwed directly on top of the sprinl<ler <br />riser. When the water is turned on, it pushes water through the riser and moves the <br /> <br />10 <br />
