SW 45th and Pendleton Inflow and Infiltration Project

Environmental Services completed construction in fall 2014 on a pilot project to keep stormwater and groundwater out of sanitary sewers. Stormwater inflow and groundwater infiltration into pipes designed to convey only sanitary sewage occur because storm drains are directly connected to the sanitary sewer or because cracks in sanitary sewer pipes allow groundwater to flow in.
