Wastewater Treatment Facilities Improvements

Black Water prepared a project engineering report evaluating the existing wastewater treatment facilities and recommended improvements for reliable operation and compliance with California Regional Water Quality Control Board regulations. Funding for the planning and construction project was secured through the State Water Resources Control Board Clean Water State Revolving Fund. Black Water completed the final design plans, specifications, and bid documents for the recommended improvements discussed in the project report. Secondary and tertiary treatment options were further evaluated prior to initiating final design and construction. Site visits to other wastewater treatment plants, with the different types of treatment technologies being considered, provided JSD operations staff the opportunity to see the treatment systems in person and gather feedback from operators. Modifications to the existing WWTP site include the addition of grit removal facilities, expansion of the emergency storage facilities, and a pump station that is capable of conveying primary treated effluent to the JSD Quartz site. Improvements to the JSD Quartz site include secondary treatment facilities, tertiary treatment and disinfection facilities, sludge treatment facilities, a composting area, and an administration office building.
