Holmes Run Pump Station Rehabilitation

The Holmes Run Pump Station, located at 6623 Dearborn Drive (near the intersection of Sleepy Hollow Road and Dearborn Drive) in Falls Church, is one of the oldest wastewater pump stations in Fairfax County and it is scheduled for rehabilitation late Fall 2022.  The existing pump station will remain, and most of the upgrades will occur inside the building.  There also will be site improvements outside the building, including the addition of a stand-by generator and odor control system (just north of the existing building), and improved vehicular access for maintenance staff.  Other site work will include extensive landscaping, tree preservation, a walled enclosure for the generator and odor control equipment, transitional screening, and permeable pavers.

To construct the improvements, a temporary pumping bypass of the pump station is needed for most of the construction duration of 20 months.  Initially, for approximately three months, a temporary bypass pipe will be in place along Sleepy Hollow Road, from the intersection of Dearborn Drive to a manhole located in front of 3420 Sleepy Hollow Road.  This pipe will be located behind the curb and gutter on the east side of the road.  This temporary pipe will be buried under road crossings and the entrance to the Methodist Church.  For driveway crossings, a ramp will be installed to allow vehicles to drive across the bypass pipe.  Construction is estimated to end in late Spring 2024.  

Questions about the project may be directed to Franklin M. Roberts, P.E., Project Manager at franklin.roberts@fairfaxcounty.gov, or call 703-324-5111 (Main), 703-324-6888 (Direct).  Please note that weather and supply chain delays may affect the scheduled completion of the project.
