Sewer Inflow & Infiltration

The Inflow and Infiltration (I&I) division was formed in 2013 for removal of inflow and infiltration from the city’s sanitary sewer system. Inflow happens when there is a direct connection to the sewer pipe such as a downspout drain or sump pump. Infiltration happens when there is a breach in the pipe such as a crack or a leaking joint. Roots can also cause a place where infiltration can occur.

Property owners have an important part in reducing inflow and infiltration.
