Inside the City of Alexandria, the City maintains the public sewers while the drain lines in your home are yours to keep flowing. A plumber clears the blockage, tells you whether it was in a branch line or the main, and points out any pipe that looks worn. Call the number on this page to be connected with a local plumber in Alexandria.
Local conditions in Alexandria
Alexandria grew from an 18th-century river port, and Old Town still has some of the oldest houses in the region, with close-in neighborhoods like Del Ray and Rosemont following later. The median home dates to 1974, so a plumber here regularly meets cast iron drains, older clay laterals and rowhouse plumbing that has been altered many times. Part of Old Town is on a combined sewer, where storm water and sewage share pipes, so heavy rain can strain the system there.
The City owns and maintains its sanitary sewers and the City-owned portions of laterals, and AlexRenew treats the wastewater. One catch: many homes with an Alexandria mailing address sit in unincorporated Fairfax County, where Fairfax County runs the sewer and its 24-hour line, 703-323-1211, takes backup reports. Check whether your address is in the City or the County before calling about the public side.
Which method fits the clog
| Approach | Best for | Keep in mind |
|---|---|---|
| Plunger or hand auger | One toilet or a sink trap | Often all a single slow fixture needs |
| Cable machine with cutter | Main line clogs and root intrusion | Opens a path but may leave buildup on the walls |
| Hydro jetting | Grease and sludge lining older pipe | Scours the full pipe; the line should be sound |
| Camera inspection | Repeat backups or suspected breaks | Shows the cause and the depth for any repair |
Symptoms not to ignore
- Water rising in the basement floor drain or lowest shower
- More than one fixture slowing down at the same time
- Gurgling in a toilet while a sink or tub drains
- A clog that returns within weeks of being cleared
- Persistent sewer smell with no obvious source
Timing and seasons
Holiday cooking sends extra fat into kitchen lines, so late fall brings a run of sink and main line calls. Summer storms are the other busy stretch, especially in older parts of town where lines are aging and, in Old Town, where sewers are partly combined. The City offers homeowners a reimbursement for a backflow preventer installed on the sewer lateral, which is worth asking about if your basement has flooded with sewage before. Clearing a clog does not usually need a permit; replacing drain pipe inside the City goes through the Department of Code Administration.
