Urban Water Management Plan

IRWD's Draft 2025 Urban Water Management Plan (UWMP) has been prepared in accordance with the California Urban Water Management Planning Act (Act) and other applicable laws. The Act requires IRWD, as an urban water supplier, to prepare and adopt a UWMP, which analyzes and projects the District’s water supply reliability during normal, single dry, and multiple dry years over the next 20 years.

The UWMP identifies imported and local water supplies needed to meet future demands, including groundwater recovery and water recycling, as well as IRWD's current and planned conservation measures. This helps to ensure that IRWD can provide the service area with a reliable supply of high-quality water to meet current and future demands. The UWMP is updated every five years and submitted to the California Department of Water Resources. The prior 2020 UWMP was adopted by IRWD’s Board in 2021.

IRWD has separately updated its Water Shortage Contingency Plan for 2025, which provides a series of response actions that IRWD may implement in the event of a water shortage due to drought or emergency.

On June 22, 2026, IRWD's Board of Directors will conduct a public hearing. At this time, the IRWD Board of Directors will consider adoption of the 2025 UWMP and 2025 Water Shortage Contingency Plan.
