Christopher S. Herrington,
Notification of Ongoing Construction: In the following weeks, engineers and crews acting on behalf of Fairfax County intend to finish construction of the force main along Georgetown Pike and begin construction along Langley Lane. The project will improve the sanitary sewer system serving the neighborhood. This project phase consists of construction of a new force main that will follow Georgetown Pike to Langley Lane. The gravity sewer at Langley Lane will be updated. Field crews will perform construction activities which may cause noise for a limited time during the day. Crew members will remain within Fairfax County’s existing sewer easements and Virginia Department of Transportation right-of-way and adhere to the county noise ordinance to prevent disturbance to property owners. The crew will work with residents to ensure driveway access throughout the project.

2020 Preliminary Engineering Report:
The project is in the planning phase and the overall project description will include the complete replacement of the existing 0.42 Million Gallons per Day (MGD) pump station. Much of the mechanical equipment is more than 20 years old and is highly corroded. The existing electrical building is undersized to hold the new modern-day mechanical equipment. There is a plan to install a new fence, repave the access road and plant trees to obscure the pump station from view. The force main is quickly reaching the end of its useful life and needs to be replaced.
The old force main will be abandoned and a new force main along Fairfax County school property will be installed, then continue 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. Phase three consists of replacing the pump station and electrical buildings. The project is in phase one with construction of the force main expected summer and fall of 2021.
It is expected the new pump station and force main will serve the surrounding community for 50 years.
Replacement of the Langley Pump Station and Force Main will:

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 project estimate is $3.4 million. As of January 25, 2019, funding in the amount of $9,631,000 is available in Fund 690C69300, Project Number WW-000001-024, to fund this project. The Langley School pump station 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.
