IRWD is required by the California Water Code Section 10632 to prepare and adopt a Water Shortage Contingency Plan (WSCP) as part of its Urban Water Management Plan. The WSCP, adopted by IRWD on June 28, 2021, includes requirements to implement locally appropriate water shortage response actions for six standard water shortage levels. The following are the rates proposed as a potential response action for each water shortage level. These rates are based on the actual cost to provide service to our customers in times of water shortage. For a detailed explanation, please refer to the District’s WSCP at bit.ly/wscp-2021. An overview of the supply shortage response actions considered for each level of water shortage can be found on Page 33, Table 3-3 of the WSCP. Achieving the WSCP reductions for each level will require a broad approach. The table below includes the target water use reduction for each level, the minimum water budget provided at each level, and the steps necessary to meet the water shortage at each level.
