Warning Signs
Signs Your Septic System Needs Repair
The EPA lists these as common signs of a failing system (EPA SepticSmart):
- Sewage backing up into drains or toilets
- Slow drains and gurgling pipes
- Standing water, damp spots or sewage odour over the tank or drain field
- Bright green, spongy grass over the drain field in dry weather
Wisconsin law treats a system as failing if it backs sewage up into the building, discharges sewage to the ground surface, or discharges it to groundwater, surface water, drain tile or bedrock (Wis. Stat. 145.01(4m)). Those faults need fixing promptly, not at the next scheduled pump-out.
Our Services
Common Septic Repairs
| Problem | Likely cause | Repair |
|---|---|---|
| Slow drains, backups | Clogged effluent filter, full tank | Clean or replace filter; pump tank |
| Solids in the drain field | Missing or corroded outlet baffle | Replace baffle or tee |
| Alarm sounding | Failed pump or float, tripped circuit, control fault | Test controls; replace failed part |
| Sewage odour in the yard | Cracked lid or riser, broken line | Replace lid or riser; repair line |
| Wet spots, surfacing effluent | Clogged or overloaded drain field | Fix upstream cause; repair or replace field |
Pumps and controls often need replacing every 10 to 20 years, and drain fields older than 25 to 30 years may start to fail (EPA septic FAQ). For pump chambers and mounds, see mound system repair. A part swap and a new drain field are very different jobs, which is why no repair gets a price until we've found the cause.
How It Works
How Fox Valley Septic Repair Works
- Diagnose. Pump and inspect the tank, check the baffles, filter and lines, test any pump and alarm, and probe the drain field.
- Explain. The fault, the ways to fix it and what each will cost, settled with you before any repair starts.
- Permit if required. Replacing a tank, drain field or mound needs a sanitary permit; most part replacements don't (see below).
- Repair, test and report. Confirm the system runs and file the service with your county.
Local Rules
Does a Septic Repair Need a Permit in Wisconsin?
Under SPS 383.21, adding or replacing a holding, treatment or dispersal component, meaning a tank, drain field or mound, requires a sanitary permit and plan approval. Replacing a pump, float, baffle or effluent filter isn't on that list, but counties can set their own permit rules, so we check with yours before work starts:
- Brown County: Planning & Land Services, Zoning Division (Chapter 11)
- Outagamie County: Development & Land Services (county sanitary page)
- Winnebago County: Zoning Department (Sanitary System Information)
- Calumet County: Planning, Zoning & Land Information (Sanitation)
A system that isn't maintained to its management plan is treated as a human health hazard (SPS 383.54), so putting off a repair can lead to a county order to correct it.

FAQ
Fox Valley Septic Repair FAQ
Can a failing drain field be repaired?
Sometimes. If solids escaped through a missing baffle or a skipped pump-out, fixing the cause and resting the field may help. If the soil is clogged throughout, the field has to be replaced; see septic system installation.
Is it a septic problem or a plumbing problem?
If you pay a sewer bill, a backup is a drain or lateral problem for a plumber. If you have a septic tank, call us.
What happens to my septic tank when sewer reaches my street?
Once you connect, the old system has to be abandoned to state code: disconnect and seal the piping, have every tank pumped and the contents disposed of properly, then remove the tanks or take off their covers and fill them with soil, gravel or another inert material (SPS 383.33). Ask your county whether it wants a record of the abandonment; we can pump the tanks for you.
Is there funding for repairs?
Not at the state level for now. DSPS says the Wisconsin Fund grant remains without funding, so it can't process applications (Wisconsin DSPS). Ask your county about local options.
