Rainfall-derived Infiltration and Inflow (RDII) into sanitary sewer
systems has long been recognized as a source of operating problems
in sewerage systems. RDII is the main cause of sanitary sewer
overflows (SSOs) to basements, streets, or nearby streams and can
also cause serious operating problems at wastewater treatment
facilities. SSOs usually contain high levels of pathogenic
microorganisms, suspended solids, toxic pollutants, floatables,
nutrients, oxygen-demanding organic components, and oil and grease.
There are serious concerns of potential health and environmental
risks associated with these discharges. The Nation's sanitary sewer
infrastructure is aging, with some sewers dating back over 100
years. Nationwide, there are more than 19,500 municipal sanitary
sewer collection systems serving an estimated 150 million people
and about 40,000 SSO events per year.
