Lathrop Consolidated Treatment Facility Surface Water Discharge Project

Lathrop Consolidated Treatment Facility Surface Water Discharge Project

The City is seeking to discharge treated effluent from the City's Consolidated Treatment Facility (CTF) that meets the requirements for disinfected tertiary recycled water in accordance with Title 22 of the California Code of Regulations to the San Joaquin River (SJR). The majority of CTF effluent would be discharged to the SJR during the winter, non-irrigation period (when river flow is relatively high) and less would be discharged in the irrigation season, during which CTF recycled water would be used for landscape irrigation. This would allow land designated under the General Plan for urban uses to be developed. Project implementation would involve repurposing approximately 1.1 miles of existing recycled water pipeline or constructing approximately 1. 7 miles of new effluent pipeline within City rights-of-way, and installing a new river side-bank or bottom-diffuser outfall to discharge excess treated effluent from the CTF to the SJR. Construction of the proposed project is expected to begin in Spring 2021 and be completed within approximately 24 to 30 months.
