In Alexandria, hydro jetting means a plumber feeds a high-pressure hose into the main drain or sewer lateral and washes out the grease, sludge, scale and roots narrowing it. It is often the better choice when cabling has only bought a few weeks of relief. Call the number on this page to be connected with a local plumber in Alexandria.
Alexandria's sewers and older blocks
Inside the City of Alexandria, the City owns and maintains the sanitary sewers and the City-owned portion of each lateral, and AlexRenew treats the wastewater. Part of Old Town is still served by a combined sewer, where storm runoff and household sewage share the same pipes. The rest of the house lateral belongs to the owner, and that private stretch is where most single-home clogs form.
The 18th-century Old Town core and close-in neighborhoods like Del Ray hold some of the oldest drain piping in Northern Virginia, while the citywide median home was built around 1974. Older cast iron and clay pipe gather scale, kitchen grease and root intrusions at the joints, which is exactly the buildup a jetter is built to strip. Keep in mind that many Alexandria mailing addresses, such as 22306 through 22312 and 22315, are actually in unincorporated Fairfax County, so the public sewer owner there is different; your bill will say who it is.
Jetting compared with cabling
| Issue | Cable machine | Hydro jetter |
|---|---|---|
| How it works | A spinning cutter punches through the blockage | Pressurized water scrubs the whole pipe wall |
| Grease and sludge | Often leaves a coating behind that reclogs | Flushes the coating on toward the City sewer |
| Roots at joints | Opens a path, and roots refill it | Cuts and rinses root hair out of the joints |
| Fragile old pipe | Gentler on a weak wall | Needs a camera check and reduced pressure first |
Signs it's past a simple clog
- A basement drain or laundry sink backs up when an upstairs toilet flushes
- Several fixtures slow down at the same time
- The same line has been cabled more than once in a year
- Sewer odor in the lower level after heavy rain
Timing and the wet months
Hard summer thunderstorms load the sewers quickly, and lower-level drains in older homes are where trouble shows first. An open, clean lateral gives wastewater a clear path out. The City also offers homeowners a reimbursement for backflow preventers installed on their sewer laterals, which block backups coming from the street side. If a camera finds broken pipe once the line is clean, the repair permit comes from the City's Department of Code Administration; Alexandria-addressed homes outside the city limits go to Fairfax County instead.
