How Does I&I Affect You?

Inflow and infiltration introduce Clear water into the sewage system and, sometimes, cause it to overflow. Once the sewer system reaches capacity, it floods sidewalks, basements, and streets. This causes significant health issues in the originating communities and those upstream. You may wonder whether this phenomenon impacts your neighborhood. Communities throughout Minneapolis, St. Paul and numerous other Riverside cities have experienced I&I, and some of them are finding ways to fight back.

How Does Infiltration and Inflow Affect You?

As you can imagine, infiltration and inflow affect you and other citizens in several ways. Wastewater contains bacterial pathogens that can cause a variety of diseases. When the wastewater backs up into rivers, streams and lakes, it contaminates water supplies distributed to numerous communities. Additionally, I&I negatively impacts wildlife, including fish and animals that drink the contaminated water.

Further, additional water makes it difficult if not impossible to properly treat all the water flowing through wastewater management plants. Therefore, poorly treated waste flows back into area waterways.

Dealing with infiltration overflow has cost taxpayers many millions of dollars. On a brighter note, there are positive things that communities and individuals can do to alleviate future incidents of I&I.
