Overhead Sewers and Flood Control in Mokena, IL
If your floor drain backs up every time a big storm rolls through, a flood control system keeps sewer water out of the basement for good. We install overhead sewer systems in Mokena homes. From our office on Jodi Road.
Does Your Mokena Home Need Flood Control?
Consider it when:
Backups Follow Storms
Water rises at the floor drain in heavy rain, not on dry days.
Your Line Checks Out
No roots or damage on camera, and it still happens.
You Have a Finished Basement
Or you're about to finish one.
There's a Basement Bathroom
Gravity drains below the street sewer are the most exposed.
How an Overhead Sewer System Works
Every drain below the street sewer's flow line, like your floor drain, a basement bathroom, or a laundry line, normally relies on gravity to reach the sewer. An overhead sewer system reroutes those drains into a sump pit instead. An ejector pump lifts that wastewater up to a line above flood level, where a check valve keeps it from flowing back down. From there, gravity carries it the rest of the way to the street sewer, the same as every drain upstairs.
Flood Control in Mokena Homes
In August 2025, storms dropped 4 to 8 inches of rain across the region, and the National Weather Service reported significant flash flooding in Mokena.
Finished Lower Levels
A lot of Mokena homes built in the 1990s and 2000s have finished basements. They're the ones most worth protecting.
Many Homes Already Have a Pit
If you already have an ejector pump for a basement bathroom, a conversion can sometimes build on it.
Check the Line First
We camera your sewer before recommending a system. A sewer repair may be enough.
Overhead Sewer vs. Backflow Valve vs. Sump Pump
Each one solves a different problem:
| Sump Pump | Backflow Valve | Overhead Sewer System | |
|---|---|---|---|
| Problem it solves | Groundwater around the foundation | Sewage flowing back into the house | Storm backups through basement drains |
| How it works | Pumps water out of a pit | A flap closes when flow reverses | Lifts basement wastewater above flood level |
| Best for | Wet soil and high water tables | Homes where a passive valve is enough | Repeat backups and finished basements |
We'll tell you which ones your basement needs.

"We initially called and Edgar came when we had flooding in our basement, and throughout multiple days of different issues being found, he talked us through each piece, explaining our options, and kept in close communication about the progress and everything that had come up. He helped clear our drain, then fixed some piping in the basement, put a liner in our pipes, and installed a sump pump, staying late to ensure we had working plumbing."
★★★★★
"So it's Christmas Eve and my sewer is backed up. J. Blanton did not hesitate or cancel my appointment. George and Mike were excellent! They were not rushed, answered all my questions. Very knowledgeable and honest, which goes a long way especially as a first time home owner."
★★★★★
"J. Blanton was great. I was not the nicest this morning when I called because I was super stressed about my plumbing being totally backed up for the second time in 6 weeks, and they were so sweet. They got someone out same day and communicated constantly until he arrived. Stephen was absolutely amazing. [...]"
