Broad Run Water Reclamation Facility

Broad Run Water Reclamation Facility (Broad Run) was constructed to accommodate future growth and to reduce loading to DC Water’s Blue Plains Treatment Plant (Blue Plains). The BRWRF was first opened in 2008 and currently treats about 8 million gallons per day (MGD) of sewage with a total current capacity of 11 MGD. Of the 8 MGD that is currently treated, about 1 MGD is distributed back to Loudoun Water customers as reclaimed water.

Wastewater is treated at Broad Run to a high degree using preliminary and primary treatment, secondary/biological treatment, ultra-filtration, and ultraviolet radiation for disinfection. Solids handling processes include combined primary and waste activated solids thickening, aerobic digestion, and dewatering. 

Highly treated effluent is released into nearby waterways. The system also allows wastewater to become reclaimed water, which can be reused for non-potable purposes. In 2019, Loudoun Water delivered 640 million gallons of reclaimed water to its customers. Visit our Reclaimed Water Program page to read more about the program.

Broad Run is currently planning future upgrades and expansions to allow Loudoun Water to serve future growth while meeting the stringent regulatory requirements associated with the Dulles Area Watershed Policy and Chesapeake Bay protection goals.
