Our wastewater engineering services

An expert overseeing wastewater treatment process at a plant

Robust wastewater collection and treatment infrastructure protects community health and the environment. Publicly Owned Treatment Works (POTWs) across the U.S. process approximately 34 billion gallons of wastewater each day. As populations in urban and semi-urban areas surge, increased effluent volumes often stretch aging wastewater treatment plants beyond capacity, leaving municipalities in urgent need of wastewater engineering solutions.

If your municipality is considering retrofitting its wastewater treatment plant (WWTP) to improve efficiency or ensure the POTW complies with the Environmental Protection Agency’s standards for effluent limits, Fehr Graham can help.


We're more than an engineering and environmental consulting firm.
