Carollo EngineersThe challenge
Expanding recycled water production for agricultural use required the City of Modesto to develop a facility capable of advanced biological nutrient removal and tertiary treatment. The project also required integrating the new treatment systems with existing wastewater infrastructure and delivering the recycled water to agricultural users beyond the treatment plant.

Large diameter (36-inch) pipeline construction
Integration of technical disciplines during design and construction
Challenge met
Filanc constructed the treatment facilities needed to support biological nutrient removal and tertiary treatment processes at the Jennings Road plant. The work included aeration basins, membrane bioreactor tanks and ultraviolet disinfection systems that produce highly treated recycled water suitable for irrigation.
Additional infrastructure included pump stations, electrical systems, standby generators and an operations center building that supports plant monitoring and control. Filanc also installed more than two miles of 36-inch pipeline conveying recycled water to the Delta-Mendota Canal, where it is delivered to agricultural users served by the Del Puerto Water District. The completed project provides a reliable recycled water supply that supports agriculture while strengthening regional water sustainability in California’s Central Valley.
