Water/Wastewater

With more than 95 years of service to water and wastewater clients, Gannett Fleming understands that, in recent years, general public- and private-sector projects have become increasingly difficult. They are complicated by stricter regulatory requirements, increasing costs, and aging infrastructure. We have performed work on more than 300 water and wastewater treatment plants, pumping stations, water storage tanks, and thousands of miles of pipelines, both water and sewer. Treatment plants have varied widely in capacity and the degree of treatment with capacities up to 180 million gallons per day (mgd). Pumping stations have ranged from small package units to large stations with capacities exceeding 100 mgd. Our pipeline experience includes gravity collection sewers, pressure mains, water distribution, and water transmission for a wide range of facilities, often while encountering a variety of site conditions.
