When sewage comes up through a basement floor drain, you are looking at Category 3 water, the most contaminated kind. It carries bacteria, waste, and whatever else was moving through the line, and it does not belong anywhere near your family or your belongings.
McLean Water Damage Co handles these backups across Columbia Pike, South Arlington, and the rest of the city. The crew arrives geared up to remove the contamination safely, disinfect what stays, and dry the structure so the space is genuinely clean again, not just pumped out.
How sewage is handled in Arlington
- 1
Call and dispatch
Whoever answers the Arlington line picks up 24/7, and the nearest crew heads out with pumps, air movers, and moisture meters.
- 2
Find the source and reach
The crew stops the water and maps its full reach, including what soaked into subfloors, wall cavities, and the units or floors nearby.
- 3
Extract and dry
The extraction crew pulls the standing water, then runs air movers and LGR dehumidifiers to a verified dry standard, not just the surface.
- 4
Verify and document
The drying team logs moisture readings until the structure is dry, then documents the loss with the photos and daily readings an adjuster needs to move a claim.
Why older Arlington laterals back up
Much of Arlington was built out decades ago, and the sewer lateral running from an older home to the main is often clay or aging pipe. Tree roots work into the joints, debris catches, and a heavy rain surcharges the system until the nearest low opening, usually a basement floor drain, becomes the relief point.
Federal health guidance is blunt about the risk from contaminated flood water, and it is worth reading before you go near a backup: cdc.gov on floods. Common triggers include:
- Roots invading an old clay lateral in a pre-1980 home
- Heavy rain surcharging the municipal main and pushing back
- Grease and debris blockages narrowing the pipe over time
- A collapsed or bellied section of the lateral holding water
- No backflow preventer on a below-grade basement fixture
Do not touch it, here is the process
The single most important thing you can do is stay out of the water and keep children and pets away from it. Black water is a contamination event, not a mopping job. The crew works in protective gear and follows a strict sequence.
- Contain the area and stop use of drains and fixtures upstream
- Remove the sewage, solids, and any unsalvageable porous materials
- Clean and apply hospital-grade disinfectant to affected surfaces
- Deodorize to clear the smell that soaks into a basement
- Dry the structure and document every step for your claim
Porous items that soaked in Category 3 water, such as carpet, pad, and wet drywall low on the wall, usually have to go. The crew separates what can be saved and disinfected from what has to be discarded, and photographs it all.

Cleaning, drying, and getting it documented
Disinfection only sticks if the space is dried out properly afterward. Damp materials keep the odor alive and invite problems, so a sewage job is not called done until the readings say it is dry.
- Set air movers and dehumidifiers sized to the affected area
- Meter framing and subfloor until they hit a documented target
- Treat and seal surfaces that will stay in place
- Provide photos, moisture logs, and a scope for your insurer
- Advise on a backflow valve so the next storm does not repeat this

IICRC S500 drying, documented for your claim
The extraction crew pulls the standing water first, usually with truck-mounted extraction so the water leaves the building instead of moving to the next room. Air movers then go in at each room's evaporation load, with LGR dehumidifiers pulling that moisture back out of the air. Most crews record readings daily and pull equipment only once the wet material sits within 2 to 4 points of a dry reference in the same building.

Why can I not just clean up the sewage myself?
Black water is Category 3, carrying bacteria and waste that pose a real health risk. It needs protective gear, proper disinfectants, and safe disposal. Keep everyone away and let a trained crew handle it.
What causes a sewer backup in older Arlington homes?
Root intrusion in aging clay laterals, heavy rain surcharging the main, and grease or debris blockages are the usual culprits. Many pre-1980 homes here have no backflow preventer, which makes a basement drain the relief point.
Can any of my basement contents be saved?
Hard, non-porous items can often be cleaned and disinfected. Porous materials like carpet, pad, and soaked drywall that touched black water usually have to be discarded. The crew sorts and documents it all.
How do you get rid of the smell?
The crew removes the contamination, applies hospital-grade disinfectant, deodorizes, and, just as important, dries the space fully. Lingering damp is what keeps the odor alive, so drying is part of the fix.
Will insurance cover a sewage backup?
Coverage varies by policy and often depends on a sewer backup endorsement. The source, the contamination, and the scope are documented so you can submit a clear claim to your carrier.
How do I stop it from happening again?
A backflow preventer on the below-grade line is the biggest safeguard, along with clearing roots from an old lateral. The crew points out the options once your basement is clean and dry.
