“The Bi-County Water Tunnel Project is an example of fantastic engineering and the critical role it plays in everyday life. It is also a testament to the importance of infrastructure investment as well as our Capital Improvements Program,” said Carla A. Reid, WSSC GM/CEO. 

John Mitchell, P.E. and Project Manager for the Bi-County Water Tunnel project, accepted the award this afternoon on behalf of WSSC. Mitchell led the project from the planning stage in 2004 through detailed design and finally construction completion in 2015. Mitchell has nearly 30 years of Project Management experience with WSSC.

The Bi-County Water Tunnel houses a 5.3 mile water pipeline with a capacity to deliver 100 million gallons of water per day to Montgomery and Prince George’s counties in Maryland.

It is 84 inches in diameter and 200 feet underground. The Project experienced several engineering and logistical challenges throughout the planning, design and construction phases. Conceptualized in the 1960s, the new pipeline will meet the future water requirements and economic development needs for many years to come.
