Sewage Cleanup in Alexandria, VA After a Basement Backup
Sewage cleanup in Alexandria, VA tends to follow the same storms that flood the streets. When heavy rain overloads the pipes, wastewater can come up through the lowest drain in the house, usually a basement floor drain, laundry sink or toilet. This is contaminated water, and it needs removal and disinfection, not just a wet vac.

Why Backups Follow Heavy Rain Here
Parts of Old Town are still served by a combined sewer that carries sewage and stormwater in a single pipe, a system dating back to the 1800s. Elsewhere in the city the pipes are separate, but intense cloudbursts like those of 2019, 2020 and 2021 still overwhelmed local capacity, and residents of Rosemont and Del Ray reported sewage in yards and basements. The city's response includes a reimbursement program specifically for backflow preventers, which tells you how common the problem is.
Keep Everyone Out of the Room
- Keep children, pets and anyone with a weakened immune system away.
- Don't run the washing machine, flush toilets or drain sinks; it all adds to the backup.
- Turn off power to the basement at the panel if you can reach it without stepping in water.
- Photograph the drain and the waterline before cleanup starts.
Our Cleanup Sequence
- Extract the sewage and standing water.
- Remove porous materials it reached: carpet and pad, drywall above the wet line, insulation and upholstered items.
- Clean and disinfect the slab, framing and anything hard enough to save.
- Dry with dehumidifiers until moisture readings are normal.
- Rebuild once the space is clean and dry.
Older Alexandria basements often have masonry walls and floors that absorb more than modern concrete; we allow extra drying time for that.
Stopping the Next One
The city's Backflow Preventer Assistance Program reimburses half the cost of a device, up to $2,000, for homes with a basement, as long as it's installed under permit by a plumber licensed by the state and city. Talk to a plumber about whether your line suits one.
If the water came under the door rather than up the drain, see flood cleanup after flash storms. The rest of what we do is on our Alexandria water damage page.
