Inflow and Infiltration

Infiltration/ Inflow (I/I) can be defined as the process by which storm water or ground water enter into the sanitary sewer system. The sewer system is designed with estimated load capacity that it can carry. I/I can cause overloading of the sewer system, consequently causing backups, and overflow during heavy rain. I/I can also erode the supporting soil surrounding a buried pipe leading o deformation and collapse.
