Spot repairs for defective work that occurred during Phase 1 will be implemented by the Contractor as soon as April 3, 2023. See community notice.
Construction for Phase 2 continues along Chain Bridge Rd and Ballantrae Ln. Phase two consists of updating the pumps at the pump station to ensure the capacity of the downstream gravity sewer is maintained, as well as gravity sewer improvements along Chain Bridge Rd and Ballantrae Ln. The objective is to replace the existing gravity sewer pipe that runs under sections of Chain Bridge Rd and Ballantrae Ln with a larger diameter pipe in the same location to accommodate higher flows. In addition, upon successful completion of the gravity sewer along Chain Bridge Road, the existing Force Main shall be abandoned in place.

2020 Preliminary Engineering Report:
The overall project description will include the complete replacement of the existing 0.42 MGD pump station. Most all the mechanical equipment is over 20 years old and is highly corroded. The existing electrical building is a little undersized to hold the new modern-day mechanical equipment. We also are planning to install a new fence, repave the access road and plant some trees to help “hide” the pump station. The forcemain is quickly reaching the end of its useful life and needs to be replaced.
We are planning to abandon the old forcemain and install a new forcemain along the Fairfax County School Property, then along Georgetown pike and into Langley Lane to its new discharge point.
The project is located to the east of Langley High School and extends along Georgetown Pike.
This is a multi-phase project planned to take place over several years.
Phase one consists of building the new force main and increasing the capacity of the gravity sewer on Langley Lane.
Phase two consists of updating the pumps at the pump station to ensure the capacity of the downstream gravity sewer is maintained, as well as gravity sewer improvements along Chain Bridge Rd and Ballantrae Ln. The objective is to replace the existing gravity sewer pipe that runs under sections of Chain Bridge Rd and Ballantrae Ln with a larger diameter pipe in the same location to accommodate higher flows. In addition, upon successful completion of the gravity sewer along Chain Bridge Road, the existing Force Main shall be abandoned in place.
Phase three consists of replacing the pump station and electrical buildings.The project is currently in phase one with construction of the force main and gravity sewer on Langley Lane expected to be complete Summer 2022.
Phase 2 has design plans ready for construction and public review, with a community meeting scheduled in June 2022.
It is expected the new pump station and force main will serve the surrounding community for at least the next 50 years.

This project will be awarded to a qualified contractor through a competitive bidding process once design efforts are completed. Potential staging areas and access points off-site will be studied. All work will be supervised by Fairfax County staff. Every effort will be made to minimize disturbances and impacts to public and private areas. Careful consideration will be given to schedule construction activities to minimize interference with recreational activities. There will be no interruption to existing sanitary sewer service.
The total project estimate is expected to be approximately $3.4 million. As of January 25, 2019, funding in the amount of $9,631,000 is currently available in Fund 690C69300, Project Number WW-000001-024, to fund this project. The Langley School PS Project is included in the FY 2021 – FY 2025 Adopted Capital Improvement Program (with Future Fiscal Years to 2030) identified as the Sanitary Sewer Replacement, Rehabilitation and Reinvestment Program.
