Southeast Surface Water Treatment Facility

Project Number: WC00057-SEWTF-001

Council District: County

The Southeast Surface Water Treatment Facility will maximize use of surface water resources and ensure clean, safe water for Fresnans. The SESWTF will be constructed on a 58-acre property southeast of the city, between North Fowler Avenue, East Floradora Avenue, North Armstrong Avenue and East Olive Avenue.

Description

The Southeast Surface Water Treatment Facility (SESWTF) will be a new water treatment facility to treat surface (river) water to drinking water standards and enable diversification of the City’s water supply. The facility will be fed with surface water from the Kings River through a newly constructed thirteen mile long Kings River Pipeline and will have initial and ultimate treatment capacities of 54 million gallons per day (mgd) and 80 mgd, respectively. This facility will provide an additional 72,000 acre-feet per year of treated (potable) water for use by residential and commercial customers throughout the City.  Implementation of this and other ongoing major projects will reduce reliance on groundwater and alleviate groundwater depletion.

Location

The Southeast Surface Water Treatment Facility will be on a 58-acre property located southeast of the City, within unincorporated area of the County of Fresno, between North Fowler Ave., East Floradora Ave., North Armstrong Ave., and East Olive Ave.

Purpose of Project

For decades, the City of Fresno relied on groundwater as its main supply. While the City of Fresno receives a small portion of surface water from the San Joaquin River, Fresnans rely on groundwater for nearly 90 percent of its water. The SESWTF will allow us to maximize use of available surface water in normal years, and reduce our dependence on groundwater resources, which are rapidly depleting. Treated surface water from the SESWTF will provide an additional 72,000 acre-feet per year of treated water to the City’s water supply and will alleviate groundwater depletion.

Project Status

Construction of the Southeast Surface Water Treatment Facility, the “backbone” of Recharge Fresno, is near completion and began delivering drinking water to Fresno homes and business in May 2018. Most heavy construction is complete. The major concrete water-holding structures are complete and most have undergone leakage testing; off-site utility and road improvements are complete with Fowler, Armstrong and Olive avenues open to traffic; exposed piping, ductwork, and electrical conduits are nearly complete; installation of large mechanical and electrical equipment is well underway; and architectural work on support buildings is ongoing. The main power substation is energized and the facility has electricity. Extensive calibration and functional testing of all equipment, systems, and treatment processes has begun. The completion of the Kings River Pipeline and Regional Transmission Mains enabled the City to deliver water from the Southeast Surface Water Treatment Facility to homes and businesses. These projects reduce dependence of groundwater, and maximize access to water fro the Kings River. The City is working to increase production to 54 million gallons per day (mgd).
