What is I & I?

Inflow and Infiltration (I/I) is the excess flow of clear water into the City's sanitary sewer system. 

  • Inflow is when clear water from illegal connections of sump pumps, downspouts, and foundation drains is channeled directly into sanitary sewer pipes.
  • Infiltration is when groundwater seeps into sewer pipes via cracks or leaky joints.
