How a sewage backup cleanup dry-out moves from wet to dry
- 1
Find every wet spot
Infrared scans and moisture meters mark where the water went before any equipment is placed.
- 2
Get the water up
Extraction wands and pumps clear floors and pad first, since leftover water only stretches the drying.
- 3
Dry the air and the structure
Air movers sweep moisture out of walls and subfloor while LGR dehumidifiers pull it from the room.
- 4
Confirm it with numbers
Readings are taken daily against dry material, and the job closes when they agree within 2 to 4 points.
Sewage water is never handled as a simple drying job. It is contaminated from the first step, so the area is sealed off, the water is extracted by a crew in protective gear and anything porous that touched it is removed. In East Boston, the existing combined sewer carries sewage while the new storm drains in the separation program carry stormwater.
Why the sewer program matters
BWSC says the separation aims to reduce combined sewer overflows to Chelsea Creek and Boston Harbor, which happen when heavy rainfall inundates the combined sewer. Phase IV runs under five contracts, from September 2025 to fall 2031, and focuses on Eagle Hill and Maverick Square. Whatever the cause of a given event, the cleanup treats the water as contaminated.
What the mitigation team removes
- Carpet, pad and rugs that soaked up the water
- Drywall and insulation the flow reached
- Cabinet bases and particleboard that swell and stay contaminated
- Soft goods and stored cardboard
Hard surfaces and framing are cleaned, treated with a disinfectant and dried, not discarded.
Clearance before rebuilding
After removal, surfaces are cleaned twice, treated and dried with air movers and dehumidifiers. Readings and a visual check decide when the area can be rebuilt. Some insurers ask for those records, so the drying team keeps them. The water-removal side is described under water extraction.

Sewage Backup Cleanup questions in East Boston, MA
Water still coming through?
Sewage in the building? Call now, any hour.
Get the area decontaminatedIs sewage water dangerous?
Yes. It can carry bacteria and viruses, which is why it is treated as Category 3 water from the first step and handled with suits, respirators and gloves.
Can carpet be saved after sewage?
No. Porous materials such as carpet, pad and low drywall soak up contamination and cannot be made safe, so they are removed and bagged.
Who fixes the cause of the backup?
A plumber clears or repairs the pipe. The cleanup crew handles the contaminated materials, and the two jobs are scheduled so the source is stopped first. Flooded lower levels follow basement flooding cleanup.
Is it safe to stay in the building?
Usually not near the affected area. Children, older adults and anyone with a weak immune system should stay out until the area is cleaned and cleared.
What does the sewer separation program do?
BWSC is building new storm drains to carry stormwater while the existing combined sewer carries sewage, to reduce overflows to Chelsea Creek and Boston Harbor. Phase IV runs from September 2025 to fall 2031.
Will an insurer cover the cleanup?
Coverage varies by policy and by the cause of the backup, so ask the insurer early and keep photos, receipts and the drying records.
