Why is there a service vehicle in my neighborhood?

Wastewater Collection Division (WCD) performs a variety of tasks to maintain, rehabilitate and operate the County’s sanitary sewer system. As a County resident, you may see WCD vehicles in your neighborhood performing inspections, cleaning and removing debris or making repairs and rehabilitating the sewer system to mitigate backups, overflows and odors.

The County inspects the sanitary sewer network by utilizing Closed Circuit Television (CCTV) equipment and a certified method of inspection that conforms to the National Association of Sewer Companies (NASSCO) for pipe and manhole assets. The inspection data is then utilized for investigative purposes, scheduling preventative maintenance and identifying assets for repair and rehabilitations.

Sanitary sewer pipes may be located in easements on private property, on sidewalks or in roadways. In order to gain access to inspect, clean or repair these assets, Fairfax County employees will be required to access the entry points of these assets. Below you will find pictures that will help you identify Fairfax County employees, vehicles and their functions, as well as access points used to perform their work.
