Septic Inspection in Corunna, MI
Most septic problems are cheaper to fix when they are found early. A professional inspection in Corunna checks how the system is built, how it is performing and whether anything is close to failing.
You might be under contract on a house or have owned your home for years. Either way, a local company that works across Shiawassee County can give you a clear written picture of your system.
What a septic inspection covers
A full inspection usually starts with locating the tank and drain field and reviewing any records on file. The inspector opens the tank, checks the liquid level and sludge depth, and looks at the inlet and outlet baffles, the tank walls and the lid. Water may be run through the house to watch how the system handles flow. The drain field is checked for wet spots, odors and signs of surfacing water. Pump chambers, alarms and filters are tested if the system has them.
Choosing the right kind of inspection
A walk-through inspection is fine as a routine check on a system you know well. For a home sale, a refinance or a system you know nothing about, choose a full inspection that opens the tank and looks at the drain field. Some lenders and counties specify which type they will accept.
When to get a septic inspection
Get an inspection before buying a home with a septic system, before listing your own, and when you refinance if the lender asks for one. It also makes sense every few years as part of routine care. Other good times are after a major backup, before adding a bedroom or bathroom, or when the home has been empty a long time. Many owners schedule an inspection at the same time as pumping to save a trip.
Reading a septic inspection report
The report should say where each part of the system is, how big the tank is and what it is made of, how full it was, and the condition of baffles, filter, lids and any pumps. It should describe how the drain field looked and list recommended repairs, with photos where possible.
Getting ready for the inspector
Find any septic permit, the original design drawing and receipts from past pumping or repairs. If you know where the tank lids are, clear grass, mulch or snow from them. Let the inspector know about any past backups or wet spots, and plan for normal water use in the house beforehand.
What to ask when you book an inspection
Ask exactly what the inspection includes, whether the tank will be opened and pumped, and whether the drain field will be tested. Ask about their experience with your type of system, how long the report takes, and whether the report format is accepted by lenders in Shiawassee County.

What inspectors look at closely around Corunna
Because most mapped soils near Corunna are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water. Corunna averages about 34 inches of precipitation a year. Mention recent heavy rain to your inspector, since it can change what the drain field shows. Frozen ground in the colder months can limit what an inspector can see, so plan inspections for a home sale early when you can.
Local conditions in Corunna that affect septic inspection
Among the mapped soils within about two miles of central Corunna, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.
Corunna averages about 34 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with January averaging 22°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
