Mandatory Measures

A. Level One (Shortage Warning – up to 10% shortage) Level 1 is a low-level shortage warning condition intended to address supply reductions of up to 10%. Measures considered Level 1 would include the following voluntary actions: • Increase public awareness of water supply situation and conservation opportunities. • Encourage diligent repair of water leaks. The measures used in Level 1 are designed to achieve reductions in outdoor over-irrigation. An enhanced public awareness campaign would be targeted toward customers that use water in excess of their water budget amounts to help them identify the source of their overuse and correct the problem. General conservation efforts include dedicated pages on IRWD’s website, information provided in the customer newsletter, and drought ‐ related presentations to groups such as city council, community associations, chambers of commerce, business groups, and schools. B. Level Two (Significant Shortage Condition – up to 20% shortage) Level 2 is a significant shortage condition intended to address supply shortages between 11% and 20%. Measures considered under Level 2 would incorporate the actions taken under Level 1, and would include the following: • Expand water conservation programs and projects, including residential survey program, large landscape survey program, outdoor education programs and workshops. • Establish water waste reporting “hotline” and increase promotion of IRWD’s Log-a-Leak water waste reporting tool. • Review of water budgets and potential adjustments to target discretionary outdoor uses for residential and landscape customers. • Prohibitions on filling of fountains, pools, and water features, as well as specific municipal uses. The measures used in Level 2 are intended to target discretionary uses of water. These measures require shorter lead time to implement, although it should be noted that rate-based measures are subject to public notice and a rate hearing process under Proposition 218.
