2020 Urban Water Management Plan - Water Shortage Contingency Plan

The Urban Water Management Planning Act requires every “urban water supplier” of a certain size to prepare and adopt an Urban Water Management Plan (UWMP) at least once every five years. Ventura County Waterworks District No. 8 serves water to a portion of the City of Simi Valley and adjacent unincorporated areas southeast and north of the City Boundary. The UWMP is a planning document in which water suppliers evaluate and compare their water supply and reliability to their existing and projected demands.

On May 17, 2021 the Board of Directors of Waterworks District No. 8 (Board) adopted the 2020 Urban Water Management Plan and 2020 Water Shortage Contingency Plan.

2022 Water Quality Report

The 2022 Water Quality Report is now available. The City of Simi Valley/Waterworks District No. 8 (District) is committed to providing you a reliable supply of safe, cost-effective, high quality drinking water.

The report provides information on where your water comes from, what it takes to deliver water to your home and/or business, and the importance of protecting our precious water resources. Consistent with the City Council's policy of transparency with the community and the public, the report raises awareness of your water quality and as in years past, provides assurance that the water provided to you, your family, and your community is high quality and safe.
