DC Water’s Blue Plains Treatment Plant, originally constructed in 1938, sits on a 150-acre site on the Potomac River and serves 4 million people in Washington, DC and suburban Virginia and Maryland.  Blue Plains is the largest advanced wastewater treatment facility of its type in the world with a rated annual average capacity of 370 million gallons per day.

Volkert led a team of specialty subconsultants and served as the prime engineer for the $84 million replacement and rehabilitation of the east and west grit removal process facilities.  The objective of the project was to upgrade the grit removal process system and reduce maintenance and operations costs.

The project included a new continuous grit removal process using submersible pumps supported by a new traveling bridge grit removal system, classifiers, new conveyance system, new grit storage and loading buildings.  Work included the design of new screening and hoisting equipment, replacement of various gates, blowers, dewatering pumps, and a new odor control system.

The grit chamber received a Craftsmanship Award from the Washington Building Congress. Volkert was recognized for outstanding work in connection with the project.
