The U.S. Environmental Protection Agency (EPA) was introduced on December 2, by President Richard Nixon. The agency is charged with protecting human health and the environment. Infiltration and inflow (I/I) is excess water that flows into sewer pipes from groundwater and stormwater. Groundwater (infiltration) seeps into sewer pipes through holes, cracks, joint failures, and faulty dirkbraeckmanvenice2017.comater rapidly flows into sewers via roof drain downspouts, foundation drains, storm drain cross-connections, and through holes in manhole covers.
Groundwater and stormwater that enters a sewer system is known as inflow and infiltration. Collection systems can be damaged when they are forced to transport more flow than they are designed to handle. Inflow and infiltration (I&I) can account for up to 45% of the annual flow to treatment plants.
