Urban Water Management Plan

The Urban Water Management Plan (UWMP) has been prepared in compliance with the requirements of Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act (Act), which were added by Statute 1983, Chapter 1009, and became effective on January 1, 1984. The Act requires “every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually” to prepare, adopt, and file a UWMP with the California Department of Water Resources (DWR) every five years.

Moulton Niguel Water District has prepared an update to its UWMP in accordance with the Act and the Water Conservation Act of 2009, commonly referred to as SBX7-7, and the guidance provided by the DWR UWMP Guidebook 2020. The District has also prepared an Addendum to its 2015 UWMP to demonstrate reduced water reliance from the Bay-Delta as part of the Delta Reform Act. Both of these documents were adopted by the Board of Directors at the June 10, 2021 Board Meeting. A copy of the adopted documents can be found below.

Water Shortage Contingency Plan

California, including Orange County, experienced significant dry year conditions in 2012-2017, which led local water agencies to declare water shortage conditions that triggered drought actions. Following the end of the statewide drought conditions, the California Legislature amended the Urban Water Management Planning Act in 2018 to include additional water shortage planning requirements. Water Code Section 10632 now mandates the adoption of a Water Shortage Contingency Plan (WSCP) with prescribed elements. Pursuant to State law, the District is required to adopt a WSCP to address specific “stages” of action to be undertaken in response to water supply shortages. The District’s WSCP has been developed to manage supply and demand during times of drought and emergencies and provides a detailed plan for actions the District may implement in the case of an actual water shortage condition. The Moulton Niguel Water District Board of Directors approved an Ordinance adopting its WSCP and Prescribing Water Conservation Rules and Regulations at its regularly scheduled Board Meeting on Thursday, May 13, 2021.
