  • Evaluate or implement specific water saving measures to achieve customer-based goals.
  • Develop a WUE program to support the established goals and obtain approval of the goals by the water system's governing body every six years..
  • Achieve a standard three-year average distribution system leakage of no more than 10 percent.
  • Report annually on progress towards achieving these goals.
