Sewage Cleanup in St. Louis

Restoration based on documented conditions

Sewage backup cleanup requires a plan based on contamination, affected materials, access, and actual jobsite hazards. Eversafe uses procedures consistent with applicable ANSI/IICRC S500 principles for water restoration.

Sewage cleanup is available across St. Louis City, St. Louis County, St. Charles County, and surrounding Missouri and Illinois communities. Eversafe's emergency phone line is staffed 24/7; scheduling depends on crew availability and the situation.

Planning a St. Louis-area restoration project

For a backup at a St. Louis-area property, tell us where it entered, which rooms and materials are affected, whether the backup is continuing, and whether a plumber or utility has already assessed the source. Cleanup and fixing the underlying plumbing or sewer issue are distinct responsibilities to clarify.

Clarify the scope before work

Discuss access, affected contents, removal, drying, cleaning, and any included repairs before authorizing work. The written scope should distinguish restoration from separate source repairs, reconstruction, or requested testing.

Should mold remediation be needed after sewage cleanup, Eversafe applies source-removal methods consistent with applicable ANSI/IICRC S520 principles. Post-remediation testing is not in the standard scope or price; it may be separately coordinated when requested or required.

Sewage events often overlap with water damage — see our St. Louis water restoration page. Contact Eversafe to discuss your situation.

What "Category 3" means in plain terms

The ANSI/IICRC S500 standard divides water into three categories, and the category — not the volume — drives how a job is planned. Category 1 is water from a clean source, like a supply line: it starts sanitary. Category 2 is gray water, such as discharge from a dishwasher or washing machine: not clean, and capable of becoming worse with time and temperature. Category 3 is grossly contaminated water: sewage, rising water from rivers or streams, and water entering from the ground surface that has picked up soil and contaminants along the way.

Two things about categories surprise most property owners. First, water can move between categories. A clean supply-line leak that sits for days in a warm building, feeding on building materials and debris, does not stay Category 1 forever. Second, category is judged by what the water carries, not how it looks — clear water that entered across contaminated ground is still Category 3. The assessment determines the category from the source and the path, and the category determines the plan.

Why does it matter? Because Category 3 changes the fundamental question of the job. With clean water, the question is what can be dried and saved. With Category 3, the question is what must be removed to eliminate contamination — and the answer, for porous materials, is usually most of what the water touched.

Is this the right service for your situation?

Not every wet floor is a sewage job, and calling it one when it isn't leads to unnecessary removal. A burst supply line to a sink is Category 1 water — the plan centers on extraction and drying, not on contamination removal. A toilet overflow from the supply tank side is a different matter than an overflow from the bowl or a backup through the drain line; the source determines the category, and similar-looking events can land in different categories.

The honest answer to "which category is my water?" usually requires an on-site assessment: where the water came from, what path it took, how long it has been there, and what it contacted. Eversafe documents those findings and plans the work from them. When the evidence shows Category 3, the scope reflects it — controlled removal, thorough cleaning, containment, and drying. When it doesn't, the customer is not sold a contamination job they don't need. Get a Free Inspection – Call (636) 219-9302.
