Baltimore Team’s Innovative Approach Eliminates Sewage Overflows During Major Storms


WASHINGTON, DC – The Baltimore, Md.-based joint venture of Gannett Fleming and Mott MacDonald has earned a National Recognition Award for exemplary engineering achievement in the American Council of Engineering Companies’ (ACEC) 54th annual Engineering Excellence Awards (EEA) for designing the Broad Creek Augmentation Conveyance System in Fort Washington, Md.

Designed for the Washington Sanitary Sewer Commission (WSSC), the project is a forward-thinking example of how to mitigate sanitary sewer overflows and provide capacity for the future, while minimizing impacts to environmentally sensitive areas, ensuring reliable service and cleaner, safer water for all. The 4.8-mile-long project features a new parallel sewer concept that provides a higher-capacity connection between the 50-year-old Broad Creek Pumping station and the Piscataway Water Resource Recovery Facility. Much of the new sewer was built using innovative microtunneling technology.

Combined with upgrades to the pump station, the system will prevent combined sanitary and storm sewer flows from spilling into area waterways. The innovative parallel pipelines allow WSSC to take one system offline for inspection, maintenance, and repairs without compromising service to customers. Close coordination between the contractor and the tunnel inspection team allowed for a rapid response to add an intervention shaft to the system, minimizing downtime and construction cost.

The project is eligible for additional honors as part of 173 entries this year representing engineering excellence from throughout the nation and the world. Judging for the awards program—known industry-wide as the “Academy Awards of the engineering industry”– took place in February and was conducted by a national 20-member panel of built-environment leaders, along with experts from government, media, and academia. Award criteria focused on uniqueness and originality, technical innovation, social and economic value, and generating excitement for the engineering profession.

Recognition of all award winners including top winners—20 Honor Awards, 16 Grand Awards, and the prestigious “Grand Conceptor Award” for the year’s most outstanding overall engineering achievement—will take place during the 2021 Virtual EEA Gala, to be held Thursday, June 17, 2021.


The American Council of Engineering Companies (ACEC) is the business association of America’s engineering industry, representing more than 5,200 independent engineering firms and more than 600,000 professionals throughout the United States engaged in the development of America’s transportation, water and energy infrastructure, along with environmental, industrial and other public and private facilities. Founded in 1906 and headquartered in Washington, D.C., ACEC is a national federation of 52 state and regional organizations.
