Poolesville runs its own sewer system and wastewater treatment plant rather than relying on WSSC Water, and some properties in and around town use private onsite systems instead. A sewer camera inspection shows what's inside the line leaving your house and where any damage is. Call the number on this page to be connected with a local plumber in Poolesville.

About Poolesville
Poolesville is a small historic town in western Montgomery County, surrounded by the County's Agricultural Reserve. The Town operates its own wastewater collection system and an enhanced nutrient removal treatment plant on Beall Street. The County's Water and Sewer Plan lists sewer service here as Town and onsite systems, so some properties aren't on municipal sewer. The median home was built around 1985, which puts many drain lines in the plastic era, with older materials possible in the historic district.
What to do now
- Stop running water if a basement or lower-level drain is backing up.
- For a sewer backup or overflow that looks like the Town's system, use the Town's emergency numbers, 240-286-3389 or 240-286-3359.
- If only your house is affected, the cause is in your own line, and a plumber is the right call.
- Expect the plumber to clear enough of the blockage to get the camera through, then film toward the street or the onsite system's inlet.
- Ask for the footage and the marked locations so any repair quote matches what was found.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| Lowest drain overflows when the washer empties | Blockage or partial collapse in the main line |
| Clog keeps coming back | Roots through a joint or a sag collecting solids |
| Wet spot or odor along the pipe route | Crack or separated joint |
| Slow drains throughout the house | Buildup narrowing the line |
Cost factors
- Access through a cleanout, toilet opening or vent
- Clearing the line before filming
- Run length, which can be longer on lots outside the town core
- Locating defects and providing a recording
Repairs are plumbing work permitted through WSSC Water and done by a plumber registered with WSSC. Work that disturbs the ground may also need a Town of Poolesville permit, since Town Hall issues building and zoning permits and utility construction permits.
Poolesville's older houses in the historic district may still have clay or cast iron drains, while homes from the 1980s and later are mostly plastic. Roots, scale and settled sections each look different on the monitor, so the video points to the right repair instead of another round of snaking. Keep a copy for your records and for any future sale.
