Washington Suburban Sanitary Commission (WSSC) Duckett Dam Intake Modifications

Meltech completed this important project for the Washington Suburban Sanitary Commission (WSSC) for the T. Howard Duckett Dam – D/S Intake Modifications in Laurel, Maryland. The T. Howard Duckett Dam went into service in 1954 with the primary purpose of providing source drinking water for WSSC Water customers. The T. Howard Duckett Dam spans from the Patuxent River between Prince George’s and Howard counties, it created the Duckett Reservoir (also known as Rocky Gorge). The reservoir holds approximately 5.5 billion gallons of source drinking water to WSSC Water’s Patuxent Water Filtration Plant for treatment. The Patuxent Plant produces approximately 30 percent of the drinking water for WSSC Water customers. 

Meltech completed this important project for the intake modifications to the Duckett Dam. The project consisted of providing a new concrete masonry unit (CMU) building at the T. Howard Duckett between the Pony Buttress and Buttress No. 11 with a new roof. 

The project also included excavation of soil under existing slab and replacement with flowable fill/stone, core drilling of buttress to provide drainage, and other miscellaneous work.
