Defense Distribution Center Wastewater Treatment Plant Replacement
The Defense Distribution Susquehanna Installation located in New Cumberland, Pennsylvania, serves as a primary distribution point for all branches of the U.S. armed forces and other federal agencies. More than 2,000 employees prepare military shipments of commercial repair parts, clothing and textiles, medical supplies, and industrial and electronic components at the center.
The installation’s wastewater treatment plant, built in the 1960s, included a corroded tank that was at risk of failure and broken screening mechanisms for incoming wastewater. The plant could not meet Pennsylvania Department of Environmental Protection standards. The U.S. Army Corps of Engineers, Baltimore District, retained Gannett Fleming to perform a study, and provide design, bid, and construction phase services for the replacement of the wastewater treatment plant. Gannett Fleming completed the project 150 days ahead of schedule and focused on: improving operational efficiencies, ensuring full compliance with pollution-control requirements, and designing it for use throughout the next 50 years.
Sylvan Shores Stormwater Management System
The 250-home Sylvan Shores community, built in the 1940s, sits along the South River of the Chesapeake Bay’s Critical Area in Riva, Maryland, lacked a stormwater management system, and regularly flooded. This allowed untreated runoff to flow directly into the Chesapeake Bay which could lead to algae blooms that cause significant threats to aquatic life.
Gannett Fleming planned, designed, and permitted the community’s stormwater system to align with Maryland’s pollution reduction goals. The company assisted the community in obtaining a Department of Natural resources grant to fund the overall project. The community benefited from the new system immediately: flood-prone homes are dry, water is no longer pooling in low-lying areas, and stormwater runoff naturally filters to remove pollutants. The project was so successful that neighboring communities are inquiring about similar systems for their developments.
