Stop Groundwater From Overwhelming Your Sewer System
Inflow & infiltration repair protects your home and helps your city's sewer system work properly.
What Is Inflow & Infiltration Repair?
Inflow and Infiltration (I&I) occurs when groundwater or stormwater enters the sanitary sewer system through cracks, joint separations, or improper connections. This extra water overwhelms the sewer system, leading to backups, overflows, and costly damage. Many Twin Cities municipalities actively encourage I&I repair through grant and funding programs.
Why Choose I&I Repair?
- Prevents sewer backups caused by groundwater infiltration
- Protects your home from sewage overflows
- Grant funding available in many Twin Cities municipalities
- Reduces strain on the public sewer system
- CIPP lining seals all infiltration points
- Helps municipalities meet EPA compliance requirements
