What Is Infiltration And Inflow?

Infiltration and inflow (I/I) is excess water that flows into sewer pipes from groundwater and stormwater.

Groundwater that enters in sewer pipes through holes, breaks, joint failures, connection failures and other openings called as Infiltration.

The surface water that enters the wastewater system from yard, roof, and footing drains, from cross-connections with storm drains and downspouts, and through holes in manhole covers is called as Inflow.
