Gainesville is served by Prince William Water, whose wastewater from western Prince William County is treated at the Upper Occoquan Service Authority plant; the lines and connections on private property belong to the owner. A sewer camera inspection films your private line to find what is causing backups or slow drains. Call the number on this page to be connected with a local plumber in Gainesville.

Local conditions in Gainesville
Gainesville grew from a railroad and farm crossroads at I-66 and U.S. 29 into newer subdivisions such as The Settlement and large shopping centers, mostly since the mid-1990s. Only about 4% of homes in ZIP 20155 were built before 1980, and the 2000s were the busiest building decade. That means plastic laterals are the rule, and the camera's usual findings are settling, separated joints, debris from construction and damage from later fencing, irrigation or patio work.
Prince William Water owns the meter and makes property owners responsible for lines and connections on private property. Its Emergency Dispatch at 703-335-7990 handles after-hours problems, outages and main breaks; customer service is 703-335-7950 on weekdays. Outlying rural parts of western Prince William may not be on public sewer, so check your bill if you are near the edge of the area.
Camera inspection vs. other first steps
| Approach | What it tells you | What it misses |
|---|---|---|
| Cabling only | Whether flow comes back | The reason the line clogged |
| Camera inspection | Material, defects and their distance from the cleanout | Line may need clearing first |
| Jetting plus camera | A clear view after grease or debris is removed | More time on site |
| Digging to look | One spot in detail | Everything else along the run |
Signs to watch for
- Slow drains in several rooms at once
- A basement shower or floor drain taking water when toilets flush
- Gurgling from toilets as the washer empties
- Trouble that started soon after landscaping or a new deck
- A sewer smell near the outside cleanout
Timing notes
Settling in newer neighborhoods can show up gradually over the first decade or two as backfill compacts, so a line that slowly gets worse is worth filming before it fails outright. Heavy summer storms can make a weak line back up. If repairs are needed, Prince William County Development Services issues plumbing permits. When you call, you are connected with an independent plumber who works in Gainesville. Mention the age of the house, any recent yard or construction work, and whether you live in a townhouse row where lines might be shared. Ask for a copy of the video for your records.
