Background

The Brighton Dam went into service in 1944 with the primary purpose of providing source drinking water for WSSC customers.  Located on Brighton Dam Road, Brookeville, it spans the Patuxent River between Montgomery and Howard counties, it created the Triadelphia Reservoir. The reservoir holds approximately 6.3 billion gallons of source drinking water that is released into the Patuxent River and then captured by T. Howard Duckett Reservoir and then to the Water Filtration Plant for treatment. The Patuxent Plant produces approximately 30 percent of the drinking water for WSSC customers. 

The dam is structurally sound, the Federal Energy Regulatory Commission and MDE inspect the dam regularly and has found that the dam is well maintained and structurally sound.  The work was performed to make repairs to the 70-year-old structure to prolong the Dam’s life into the future.
