El Dorado Hills Water Treatment Plant Expansion

The El Dorado Hills Water Treatment Plant Expansion project aims to modernize and significantly upgrade the existing treatment facility to ensure long-term reliability, regulatory compliance, and resilience against seasonal variations in water quality from Folsom Lake. The initiative will increase the plant’s authorized capacity from 19.5 million gallons per day to 24 million gallons per day, with infrastructure designed to support a potential future expansion up to 31.5 million gallons per day. This involves the removal of obsolete equipment and the installation of new treatment systems, piping, electrical infrastructure, and associated utilities to enhance operational efficiency and safety standards. The project is structured to proceed in phases over five years to maintain continuous water service without interruption to customers, with construction activities scheduled intermittently based on the timing of grant funding and financial availability. Construction will require the use of heavy machinery such as cranes, dump trucks, concrete and pump trucks, backhoes, welding equipment, loaders, generators, forklifts, and air compressors to execute the scope of work. All activities will be coordinated to minimize disruption to ongoing plant operations and surrounding communities. The project is managed by the El Dorado Irrigation District in California, with the primary place of performance located in Placerville, zip code 95726. Michael C. Baron serves as the Environmental Review Analyst and primary point of contact for inquiries regarding the project, which was posted as a forecast on August 10, 2026. Specific details regarding funding, procurement timelines, and contracting opportunities will depend on the availability of external financing and grant approvals.
