Echo Water Tertiary Treatment Facilities (TTF)

Elk Grove, CA

This project was part of the larger EchoWater Project. The new “tertiary” treatment plant processes for ammonia and nitrate removal, filtration and enhanced disinfection. Using a process called “biological nutrient removal” (BNR), the plant will eliminate nearly all ammonia and most nitrate from the effluent (treated water), addressing concerns about possible impacts these constituents may have on the ecosystem. Filtration will be added to remove smaller particles and more pathogens from the effluent (as compared with the existing treatment process).
