Sewer repair refers to the process of restoring, replacing, or rehabilitating damaged or deteriorated sections of a sewer system — the network of underground pipes that carries wastewater or stormwater away from homes, businesses, and streets to a treatment facility or discharge point.

In residential settings, sewer repair typically involves fixing the private sewer lateral — the pipe that connects a home’s plumbing system to the municipal sewer main — to restore proper flow and prevent leaks, backups, or contamination.

​

-Pipe Excavation and Replacement: Digging up and replacing cracked, collapsed, or root-infested sections of pipe.

​

-Trenchless Repair (CIPP or Pipe Bursting): Using cured-in-place pipe (CIPP) lining or pipe bursting technology to repair or replace a pipe without full excavation.

​

-Joint Sealing and Grouting: Sealing leaking pipe joints or cracks to prevent groundwater infiltration or sewage exfiltration.

​

-Sewer Lateral Replacement: Installing a new private sewer lateral from the house to the municipal connection point.

​

-Manhole or Cleanout Repair: Fixing access structures to maintain safe entry for inspection and maintenance.

​

• Restore full sewer function and flow capacity.

• Prevent sewage backups into homes or streets.

• Eliminate leaks that allow groundwater infiltration or soil erosion.

• Protect public health and water quality by containing wastewater.

• Work must comply with the Illinois Plumbing Code (77 Ill. Adm. Code 890) and local building or sewer ordinances.

• Many cities (e.g., Chicago, Naperville) require a plumbing permit and inspection for sewer repairs.

• Municipalities may share responsibility for repairs depending on whether the issue lies in the private lateral or public main.
