Document Description
Castaic Lake Water Agency (CLWA) proposes to expand the existing Earl Schmidt Filtration Plant (ESFP) from 33.6 million gallons per day (mgd) to 56 mgd. The proposed project includes several main components: improvements to the existing raw water system, including replacement of the existing raw water pumping plant, referred to as the Intake Pumping Station (IPS), with a 56 mgd capacity pump facility and installation of a 54-inch bypass pipeline within the existing IPS easement to improve the existing raw water gravity flow system; and at the filtration plant, construction of a new structure containing new ozone facilities for primary disinfection and chloramine system for secondary disinfection; prefiltration improvements including new contact clarifiers and other equipment within a new structure; conversion of the filtration system to deep bed monomedium filters using anthrasite filter media and related equipment upgrades; and modification to the washwater recovery system including installation of a new treatment system within an existing structure. Other improvements include replacement of the existing septic system, installation of a back-up power system; and related chemical, communication and water piping systems. The proposed additional pipelines and piping systems for the project would not require acquisition of additional easements or right-of-way.
