Title

Stockton East Water District - Efficiency Enhancement Project

Description

The project will consist of the design and construction of enhancements to the existing drinking water treatment facility to improve water quality, and conserve energy, chemicals and water. These facilities were originally constructed in 1977-78 to operate conventionally, with a treatment train consisting of coagulation, flocculation, sedimentation, filtration and disinfection. In 1990, these facilities were modified and operated frequently as a direct filtration type facility. The enhancements will allow the facility to be operated more conventionally, resulting in the energy, chemical and water savings. Enhancements include new equipment and plumbing for a rapid mix facility, a new pretreatment complex (coagulation-flocculation-sedimentation basin), and changes to existing facilities to accommodate this new complex. These enhancements will result in lower turbidity levels as water arrives at the existing filters, requiring less frequent filter backwashes, saving energy and water. The enhanced facility will optimize chemical demands, resulting in savings in the amount of chemical applied during the drinking water treatment process.
