Site work for a water / sewer project in San Luis Obispo, California. Conceptual plans call for site work for a water / sewer project.

The City currently operates two potable reservoirs (Tank #1 and #2) that are estimated to be 60 years old. Reservoir #2 is a 7.44 million-gallon (MG) reservoir equipped with floating covers that had previously been identified to be replaced in 2015. This reservoir supplies about half of the City`s potable water needs. Because the reservoir is one big basin, the entire storage volume must be taken out-of-service for reservoir maintenance. The water distribution hydraulic model, identified opportunities to consolidate water distribution zones to improve operations, reduce pumping needs, eliminate tanks and pump stations that would otherwise require replacement, improve fire flow, and improve available fire storage. Replacement of Reservoir #2 with a new High-Pressure Zone (HPZ) water storage tank will include construction of two new 2.5 MG above-ground tanks at the existing reservoir site or equivalent elevation. This will provide critical redundancy and allow for tank maintenance without service interruption. It will also be designed to increase water mixing in the reservoir, which will in turn lessen the overall age of water. Older water age contributes to disinfection byproducts, a regulated substance which may be harmful to human health. The study phase will research constructability and identify funding options, and begin in property acquisition, preliminary designs, and environmental clearances needed to secure State or Federal funding This project is included in the City of San Luis Obispo's FY 2023-2028 Capital Improvement Plan (CIP). As of October 4, 2023, information regarding a design team or a general contractor is not available. Funding is anticipated from 2024 to 2026.* *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
