One city with two treatment plants

O’Fallon’s Sewer Division runs the Rieder Road treatment plant, which serves about three quarters of O’Fallon and half of Shiloh. Caseyville Township’s plant takes the rest. Either way, the city’s line ends at its main; its backup guide says the city is not allowed by law to work on private property, so the lateral is yours.

Permits, inspections and tap fees

Repairing or replacing a lateral in O’Fallon takes a Sewer Lateral Repair or Replacement Permit, and Public Works inspects the work (618-624-4500, extension 3). A failed second inspection costs $25. For new construction, the single-family sewer tap fee is $3,000.

With a median build year of 1995, 35 years younger than Belleville’s, most O’Fallon laterals went in after Orangeburg pipe fell out of use around 1970. That makes the camera even more important here: on younger pipe, the cause of a backup is worth seeing before anyone recommends replacing the line.

Answers

Common sewer questions in O'Fallon

Who fixes a sewer backup in O’Fallon, IL?

If the city main is flowing, the owner does. O’Fallon’s backup guide says the city cannot legally work on private property, so the lateral from the house to the main is the owner’s responsibility. We clear it, camera it, and repair it if the camera finds a break.

How much is the sewer tap fee in O’Fallon?

$3,000 for a single-family home, according to the city’s sewer tap fee schedule. It applies to new connections, so it is part of the cost of a new house or a new building lot, along with the trenching and the lateral itself. A failed second inspection adds $25.

Do I need a permit to repair a sewer lateral in O’Fallon?

Yes. O’Fallon issues a Sewer Lateral Repair or Replacement Permit, and Public Works inspects the work; the inspection line is 618-624-4500, extension 3. We line up the permit and the inspection as part of the job, so the trench is ready when the inspector arrives.

Which treatment plant serves O’Fallon?

Mostly O’Fallon’s own Rieder Road plant, which serves about three quarters of O’Fallon and half of Shiloh. The rest of the city drains to Caseyville Township’s plant. Either way, the lateral from your house to the public main is yours to maintain.
