Sanitary Sewer System Master Plan
Update: the Sanitary Sewer System Master Plan is currently being revised.
The Sanitary Sewer System Master Plan (adopted Dec. 2002) evaluates the system facilities, practices, programs, policies and improvements needed to provide and maintain adequate service into the future. Our sewer system collects and treats wastewater produced in the County, as well as some adjoining portions of Fairfax County, Alexandria and Falls Church.
The plan is available here. 2002 Sanitary Sewer Collection System Master Plan
There are several maintenance projects and programs to ensure that the sanitary sewer system continues to operate effectively and efficiently, and to renew the aging infrastructure.
