Sewer and drain service in Wilsonville, IL
Half of Wilsonville’s houses are older than 1949, and a stopped-up line under one of those yards is a sewer job. There’s no need to start with a plumber.
Three neighbors within 3 miles, three different medians
The Census median for Wilsonville is 1949. Around it, Dorchester reads 1947, Mount Clare 1962 and Sawyerville 1976. Those three sit between about 2 and 3 miles away, and they span nearly 30 years.
Wilsonville’s number leans old. Some of the village’s pipe could be clay with rigid mortared joints, which let roots in. Newer replacements are just as possible, since a sewer line doesn’t have to be as old as the house above it. Footage from your own line sorts that out.
A village permit, and who to ask
The EPA’s list shows a Wilsonville STP under the Village of Wilsonville at 4305 Wilsonville Road, on general permit ILG580172. That’s a record of who holds it and doesn’t map any house to it. For a Macoupin County village of 492 people, we found no published lateral rule, so put the question to the village directly.
Illinois repealed its backwater valve section in 2004, so no state rule requires one on a Wilsonville house. We’re 27.6 miles away in Granite City. On a line here, we can offer:
- Main drain cleaning for a blockage
- Camera inspection when the cause isn’t clear
- Repair or replacement once you’ve seen the pipe

Answers
Wilsonville: sewer and drain questions
Does the Village of Wilsonville, IL hold a sewage permit?
Yes, the EPA’s list shows one under that name, at 4305 Wilsonville Road, general permit ILG580172. It records who holds the permit and may not reflect every detail of how the system runs today. For how your own Wilsonville house is connected, the village is the place to ask.
What kind of sewer pipe is under a 1949 house in Wilsonville, IL?
It may be clay, though nobody can say from the build year alone. Clay from before World War II had rigid joints of oakum and mortar. Orangeburg came into wide use soon after, and either may since have been replaced. A camera run names what’s really down there.
Do I need a backwater valve in Wilsonville, Illinois?
State law doesn’t require one, because Illinois repealed its plumbing code section on backwater valves in 2004. Whether one makes sense depends on your house and how its line behaves. Ask the village if it has a local rule, then have someone look at your line before you decide.
Do I keep the camera video from a Wilsonville, IL inspection?
Yes, the footage is yours. That matters if you’re selling a Wilsonville house, comparing repair bids or just want a record of where things stand. You can show it to the village, to a buyer or to another contractor, and they’ll all be looking at the same pipe.
