The first hour when sewage backs up in Alexandria
Stop adding water
Stop using water in the house, keep people and pets out of the affected rooms and do not flush toilets that drain toward the backup.
Make the power safe
If the backup is near outlets or the panel and you can reach the breaker without entering water, turn off power to the area. Otherwise leave it alone.
Check whether the neighborhood is affected
A backup during heavy rain can involve the city's system. Ask neighbors whether their drains are slow too, then ask the city whether the problem is in the public sewer or in your lateral.
Call for the cleanup
Call 1-888-293-5663. A crew arrives in protective equipment, contains the area and starts removing standing water and contaminated materials.
Photograph before anything moves
Photograph the damage and the affected belongings, and leave porous items in place for the crew to handle.
A combined sewer system, and what it means at your drain
The City of Alexandria owns and operates a combined sewer system, which carries sanitary sewage and storm water in the same pipes. The city's own page explains that in significant storms such a system can fill beyond its capacity, and that overflow outfalls act as a relief valve, discharging to waterways instead of backing up into homes and businesses. It lists four outfalls: Pendleton Street, Royal Street, Duke Street and Hooffs Run.
None of that keeps every cellar dry. A blockage, a surcharge or a failed pump can still push waste back through the lowest drain, and the combined system is one more reason a heavy rain and a sewage backup can arrive together. Whatever the cause, waste in living space is Category 3 water.
Whose pipe: the lateral rules the city publishes
Alexandria's sewer and hydrant maintenance page says the rule depends on when the lateral was installed. For laterals installed before July 1, 1955, the property owner maintains and repairs the lateral from the curb to the property. For laterals installed on or after that date, the property owner is responsible for everything from the infrastructure to the sewer main. Stormwater laterals are the property owner's responsibility as well.
That wording is the city's, and a particular address can differ, so confirm yours with the city before you spend money on a repair. For cleanup inside the building, the question of whose pipe it was does not change the work.
Cleaning historic cellars and bungalow basements
Old Town cellars have masonry foundations dug before waterproofing existed, and their brick, mortar and lime-based finishes are porous. Sewage soaks into them, so the plan is removal of what cannot be cleaned, careful cleaning and antimicrobial treatment of what can, and drying to a documented level. Del Ray and Rosemont bungalow basements are shallower and often finished, with carpet, pad and drywall that all have to go.
Historic demolition brings lead paint and possible asbestos into the work, so suspect materials are tested before they are disturbed, and a building in a historic district may need city approval before any exterior change.

Frequently asked questions
Who do I call for a sewer backup in Alexandria, VA?
The city's sewer page describes the lateral rules and lists Alex311, 311 or 703-746-4311, as its service line, and Virginia American Water, 1-800-272-1325, for water emergencies. Ask the city whether the blockage is in its sewer. For cleanup inside the building, call Restoration Doctor at 1-888-293-5663.
How fast can you get to a sewage backup in Alexandria?
Dispatch runs 24 hours a day, and contamination worsens by the hour. We can be on-site in as little as 60 minutes across the Northern Virginia core. Response times vary based on crew availability and demand. Old Town streets and parking can slow a crew, so tell us about access when you call.
Is Alexandria's combined sewer the reason my basement backed up?
It can be one factor, and a heavy rain can overload any system. The city says its overflow outfalls are designed to act as a relief valve in heavy rain instead of backing up into buildings, but blockages and failed pumps still cause backups. A plumber or the city can tell you which applies at your address.
Who is responsible for the sewer lateral in Alexandria?
The city says it depends on installation date: before July 1, 1955, the property owner maintains the lateral from the curb to the property; on or after that date, the property owner is responsible from the infrastructure to the sewer main. Confirm the details for your address with the city.
Can historic brick be cleaned after a sewage backup?
Often, yes, with care. Brick and masonry are porous, so they are cleaned, treated with EPA-registered antimicrobials and dried to a documented level, while plaster and other materials that cannot be cleaned are removed. What can be saved depends on how deeply the contamination went.
Who is the best sewage cleanup company in Alexandria, VA?
No neutral ranking of Alexandria sewage cleanup companies exists on this site, and we do not say we are first. Ask each company how it handles porous brick and old plaster, whether it tests for lead and asbestos, how it documents the work and for a license number you can look up. Ours is Virginia DPOR Class A contractor license 2705191604.
