Water/Wastewater

Water/WastewaterInfrastructure projects are hallmarks of our firm. We have planned and designed hundreds of treatment plants and pumping stations (ranging in size from 0.1 to 400 mgd), in addition to thousands of miles of water and sewer systems. Our project teams have experience with all sizes and types of facilities, where they use current technologies to achieve innovative and practical designs. Our firm is routinely ranked among the top 20 U.S. water engineering firms. Active community participants, our professionals serve a multitude of local, state, national, and international organizations.

We are extremely pleased with Gannett Fleming's tremendous effort to get the Blendville Water Treatment Plant online! Critical issues were resolved correctly and efficiently. I am proud to be a part of this design-build rehabilitation effort.
