AI Contract Overview

The Central Coast Water Authority is initiating the Filter Multimedia and Underdrain Nozzle Replacement Project at the Polonia Pass Water Treatment Plant located in Shandon, California. This project is critical for maintaining regulatory compliance and operational efficiency by preventing clogging and excessive head loss within the treatment process. The scope of work involves the removal and replacement of both layers of filter media and underdrain nozzles in four of the system's eight multimedia filters, as well as repairing filter basin concrete surfaces and leveling backwash troughs where feasible. The project is classified under NAICS code 237990 and is designated as a forecast with a posted date of May 29, 2026. It is exempt from the California Environmental Quality Act under sections 15061(b)(3), 15301, and 15302, as the work constitutes a replacement or reconstruction that maintains the same purpose and capacity on the existing site. Peter Thompson, the Executive Director of the Central Coast Water Authority, serves as the primary point of contact for this effort.

Full Description

The Central Coast Water Authority (CCWA) is a joint powers agency formed to construct, own, and operate certain facilities needed to treat, convey, and deliver State Water Project (SWP) water to its project participants retail water providers and end users located within the County. The Polonia Pass Water Treatment Plant (WTP) is one of CCWA's facilities and stores treatment chemicals in chemical tanks. The condition of the multimedia filters at the WTP is a high priority due to their critical role in the treatment process and regulatory compliance. Proper filter performance is essential to prevent clogging, excessive head loss, and inefficient backwash cycles, all of which can adversely affect WTP operations. Filtration of settled water is a core component of overall treatment capacity and is achieved through eight multimedia filters, within the system. Water percolates from the top of each filter through a layer of granular activated carbon and sand and flows through an underdrain system to the chlorine contact basin. CCWA intends to remove and replace both layers of filter media and the underdrain nozzles in four of the filters, repairing filter basin concrete surfaces, and leveling backwash troughs to extent feasible.
