Inflow And Infiltration

Extraneous flow entering a sewer is generally categorized as inflow or infiltration. Inflow generally occurs from surface runoff via roof leaders, yard and area away drains, and flooding of manhole covers. Infiltration usually occurs by water seeping into pipes or manholes from leaky joints, crushed or collapsed pipe segments, leaky lateral connections or other pipe failures. Extraneous flows may result in unnecessary pollution, as these reduce effective collection system and treatment plant facilities.

Details of principal methods of reducing both infiltration and inflow through rehabilitation are found in EPA 1977.
