Full Description

The City's Public Works Department manages the City's water storage and distribution facilities consisting of 11 Calleguas turnouts (connections to the Calleguas Municipal Water District supply), four hydropneumatic pump stations, 16 pump stations, 16 reservoirs, and two boosting stations. Many of these sites need improvements to address enhanced wildfire resiliency, site drainage, accidental tank overflow containment, pump and electrical equipment enclosures, fencing, and the addition of emergency generators and disinfection boosting stations. In December 2023 a comprehensive Citywide Water Storage Optimization Study was concluded, addressing water quality improvements within the City's water distribution network due to reduced demand and longer water age in the reservoirs after the 2022 drought. The study identified La Granda and Lang Ranch Reservoirs as high-priority sites for the installation of a permanent disinfection boosting system to assist with water quality.
