Line 1: '''Infiltration/Inflow''' ('''I/I''' or '''I&I''') ~~causes~~is ~~dilution~~the inprocess of [[groundwater]], or water from sources other than domestic wastewater, entering [[sanitary sewer]]s. ~~Dilution~~I/I ofcauses ~~sewage~~dilution in sanitary sewers, which decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity. Although inflow is technically different from infiltration, it may be difficult to determine which is causing dilution problems in inaccessible sewers.
