Patterson Pass Water Treatment Plant Upgrades and Ozonation Project Environmental Documents
This project is designed to improve water quality, taste and odor at the aging Patterson Pass Water Treatment Plant (PPWTP). The project will also increase and stabilize the treatment plant’s production capacity from 12 to 24 million gallons per day, as well as add clearwell storage, new filters, renewal replacement and some additional plant rehabilitation. Decades in the planning, this project highlights the agency’s efforts in long-term planning, fiscal responsibility and commitment to water quality and public health.
