St. Charles County, MO

A lot of Wentzville homes are new enough that owners don't expect sewer trouble — so a backup in a ten- or fifteen-year-old house catches people off guard. We clear the line with our sewer auger, and if you want answers, we follow up with a camera so you can see what caused it.

## Local conditions in Wentzville

Much of Wentzville was built out in the last few decades, in subdivisions off Wentzville Parkway, Highway Z and Highway A. Those homes generally have PVC laterals, and clogs there tend to come from wipes, grease, construction debris left in the line, or a low spot where backfilled soil settled after the house went in.

The older blocks around historic downtown, near Pearce Boulevard and Main Street, are different. Older laterals there may be clay tile, and roots from mature trees can work into the joints and catch paper and debris.

In Wentzville the City runs the public sewer main, while the lateral from your house out to that main is generally the property owner's to maintain. If water backs up into your lowest drain, or more than one fixture gurgles or drains slowly at once, the problem is usually in the main line — that's the time to call us.

## Frequently asked questions

### My Wentzville house is fairly new. Why would the sewer clog?

Newer PVC lines usually clog from wipes, grease, leftover construction debris or a sag where the ground settled after building. A camera check after cleaning shows which one it is.

### Who is responsible for my sewer lateral in Wentzville?

The City of Wentzville handles the public sewer main. The lateral from your house to the main is generally the property owner's responsibility, so check with the City if you're unsure where your part ends.

### When should I call instead of using a plunger?

Call when your lowest drain backs up, several fixtures drain slowly at once, or the clog keeps coming back. Those point to the main line, not a single drain.

### Do you take emergency calls in Wentzville?

We take emergency calls. If sewage is backing up, call 636-978-3478 and tell us what's happening.
