Document Description
The Western Municipal Water District proposes several different alternatives for updating the sewer system and water supply infrastructure within the city of Murrieta through updating master plans for the sanitary sewer system and water system. The Murrieta Water and Sewer Master Plan Project proposes the upsizing and replacement of water supply pipelines, improvements to pump stations and water connections, and new sewer mains. These Projects provide a long-term solution to water supply and sewer infrastructure issues for the District's service area within the city of Murrieta. These master plans include the November 2021 Murrieta Retail Area Water Master Plan Update and the November 2021 Murrieta Sewer Master Plan. The Master Plans are available for review at WMWD. In total 5 capital improvement projects (CIPs) are proposed as part of the Water Master Plan including new storage, new/upsized pipe, and supply alternatives. 25 CIPs are proposed as part of the Sewer Master Plan which include the installation of new or upsizing of existing sewer pipe throughout the City of Murrieta.
