Sector: 

Clark Civil, in a joint venture with Ulliman Schutte, is improving the Headworks and Wet Weather Equalization Facilities at the Back River Waste Water Treatment Plant in Baltimore, Maryland.

The project team is replacing the plant’s existing headworks to increase influent capacity to 469 million gallons per day. The team is also improving screening facilities, pumping stations, and the grit removal process, as well as construct two above-grade tanks to provide 36 million gallons of storage for wet weather.

Prior to this contract, Clark provided over a year of preconstruction services, including the development of alternative technical concepts to comply with stricter water quality requirements for facility improvements.

In the field, Clark’s team will update the Back River Waste Water Treatment Plant to address storm water run-off and hydraulic restrictions to prevent backups and overflows to the wastewater system during storm events.

Clark Foundations and Clark Concrete are part of the project team and will perform support of excavation and cast-in-place concrete work, respectively.
