Abstract/Contents:"Utah is the second driest and one of the fastest growing states in the nation. Residents have enjoyed inexpensive water for many years but the current water supply will not meet future demand. In 1999, the "Slow the Flow, Save H2O" water conservation education program was initiated by Jordan Valley Water Conservancy District. TV and radio ads taught correct irrigation scheduling, water wise landscaping, and a toll-free telephone number was established for scheduling a free irrigation water audit at their home. This program is now in its fifth year and irrigation system audits and water use records of over 4,500 residential and 120 large water user sites have been completed by Utah State University Extension interns. The average resident uses twice as much water as a healthy lawn requires. Parks, churches, apartments and schools studied were more wasteful than homeowners, using nearly three times as much water than required. The year following a site evaluation, participants were able to reduce their water use by 20-60%. The turf water requirement (net evapotranspiration, ET) for the Salt Lake City area was confirmed at near 24 inches of water per season at the Demonstration Gardens located at the Jordan Valley Water Conservancy District Headquarters and is the value used for percent waste calculations. Participants in this six-county Utah study use culinary water for both lawns (67% outdoors) and drinking water (33% indoors). The average distribution uniformity (DU) of the irrigation system was 52% with a precipitation rate (PR) of 1.4 inches per hour for fixed popup spray heads (range of 3.7 inches to 0.7 inch per hour at the 95% confidence level). For rotor heads, the average distribution uniformity was 58% with an average precipitation rate of 0.7 inches (range of 2.3 inches to 0.1 inch per hour). The average root depth of the bluegrass lawns was only 5.6 inches. The average residential hose connection has a water pressure of 73 pounds per square inch with a hose output of 8.2 gallons each minute."
