Title

Expansion of Earl Schmidt Filtration Plant

Description

CLWA, the lead agency of compliance with the California Environmental Quality Act (CEQA), plans to upgrade and expand the treatment system of the existing ESFP from 33.6 million gallons per day (mgd) to 56 mgd. Originally built in 1980 and expanded in 1987, the ESFP treats surface water supplied to CLWA by the State Water Project (SWP). The project includes several main components: improvements to the existing water conveyance system, including replacement of the existing raw water pumping plant, referred to as the IPS, with a 56 mgd capacity pump facility and installation of a 54-inch bypass pipeline within the existing IPS easement to improve the raw water gravity flow system; and at the filtration plant, construction of a new structure containing new ozone facilities for primary disinfection and chemical system for secondary disinfection; pre-filtration improvements including new contact clarifiers and other equipment within a new structure; conversion of filtration system deep bed monomedium filters using anthrasite filter media and related equipment upgrades; and modifications to the washwater recovery system including installation of a new treatment system within an existing structure. The additional pipelines and piping systems for the project would not require acquistion of additional easements or right-of-way. The existing ESFP septic system would also be replaced with a septic system of the same capacity at the ESFP site.
