More stringent wastewater treatment regulations place a premium on good engineering design. GD&F has a long tradition of excellence in process treatment. We have successfully engineered more than 100 treatment facilities up to 60 MGD in capacity.

Our staff of process scientists and engineers is at the forefront on new technology. Recently, our focus is on nutrient removal technologies using advanced processes. We have extensive experience with all “suspended growth” and “attached growth” treatment systems.
