I&I Repair

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.
