Safe steps when sewage backs up
- 1
Stay out of the water
Sewage carries bacteria and viruses, so keep people and pets away and avoid walking through it.
- 2
Stop using the drains
Do not flush or run water if the backup is still happening, since it adds to the flow.
- 3
Open windows if safe
Fresh air helps while the crew is on the way, but keep doors to clean rooms closed.

Photograph and call
Record the backup and the rooms it reached, then phone the crew and a plumber.
Why sewage is handled differently
Sewage carries pathogens into porous materials that cannot be cleaned. Carpet, pad and drywall it touched are removed, and hard surfaces are cleaned, treated and dried.
- Water category
- Category 3, with waste, bacteria and other contaminants present throughout.
- Typical class
- Class 2 or 3, depending on how far it spread.
- Equipment
- Wet vacuums, HEPA air scrubbers, antimicrobial products and dehumidifiers.
- Drying goal
- Clean, treated and dry surfaces with readings logged after cleaning.
The island's sewage reaches the mainland through one underwater force main beneath Sarasota Bay, and the town is building a second, redundant main. In June 2020 a force main break on the mainland spilled sewage near the bay for about two weeks. When sewage comes up inside a building instead, it is a private emergency with its own steps. The first calls usually go to a plumber to clear the blockage and to the crew to stop the damage from spreading.
What a sewage cleanup involves
- Seals off the affected area with containment so waste does not spread
- Extracts contaminated water with pumps and wet vacuums
- Removes carpet, pad, drywall and other porous materials the water touched
- Cleans and treats framing and hard surfaces with antimicrobial products
- Runs HEPA air scrubbers and dehumidifiers during drying
- Documents each step with photos and readings for the claim
- Sanitizes tools and equipment before leaving each contaminated zone

(888) 621-2041Phone the cleanup crewWhere the problem starts
The Town of Longboat Key provides wastewater service, but town ownership ends at the property line, and owners are responsible for their own laterals beyond it. A backup that starts in a private lateral is the owner's to repair. After Hurricane Helene, water and wastewater service problems continued across the island for a while.
Storms and wastewater
Storm water and heavy rain can overwhelm drains and push sewage up through fixtures. After Hurricane Milton, wastewater service was restored on October 13, 2024 with a boil water advisory still in effect, a reminder that service and building problems can overlap. Insurance for sewer backup is often separate, so the crew keeps photos and records of the water type.
A minor bowl overflow is covered under toilet overflow cleanup, and flooding that brought sewage in belongs with storm and flood cleanup.
