Greenbelt's sewer is run by WSSC Water, and the City directs residents to WSSC for sewer emergencies in the street. Clogs inside the home or in the private line are a plumber's job, and many Greenbelt homes have plumbing that dates from the 1930s through the 1970s. Call the number on this page to be connected with a local plumber in Greenbelt.

What happens when you call
The number on this page connects you with an independent plumber who serves Greenbelt. Expect a few questions: which drains are slow or backing up, whether water has come up through a floor drain or tub, and whether you live in a detached house, an attached home or an apartment. Where units share drain lines, the plumber may need to coordinate with the cooperative or building manager before working on a shared line.
On site, the plumber usually starts at the nearest access point, a cleanout or the fixture itself, and runs a cable or jetter toward the blockage. If the line clogs again quickly or roots come back on the cable head, a camera inspection is the next step.
What affects cost
- Depth of the clog: a fixture trap is quick; the main line to the street takes longer.
- Access: older homes may lack an exterior cleanout, which adds labor.
- Method: cable, hydro jetting and camera work are often separate charges.
- Pipe condition: brittle cast iron or root-filled clay can turn a cleaning into a repair.
- Timing: after-hours visits cost more.
Greenbelt drain conditions
Greenbelt was the first and largest of the New Deal Greenbelt Towns, and the median home in the city was built in 1976. That leaves a wide range, from original 1930s plumbing in the historic core around Roosevelt Center to much later construction elsewhere in the city. Older cast iron drains develop scale and rough spots that grab grease and paper.
WSSC's tap water analysis shows Potomac plant water averaging about 140 mg/L hardness and Patuxent plant water about 64 mg/L, and which plant serves an address varies. Moderately hard water combines with soap to leave a film in tub and shower lines over time. Sewer emergencies in the street go to WSSC Water's Emergency Service Center at 301-206-4002. If a damaged line needs replacing, WSSC issues the plumbing permit, and Greenbelt also requires its own City building permit for projects that need a County building permit.
Before the plumber arrives
- Stop running water to the affected drains
- Clear a path to the cleanout, basement floor drain and any affected toilet
- Move stored items away from a floor drain that has backed up
- Note when the problem started and which fixtures were involved
- Tell your cooperative or building office if you share walls or lines
