Report to Congress on Combined Sewer Overflows and Sanitary Sewer Overflows

EPA recently released a Report to Congress on the impacts and control of combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs). This report was published to comply with a request from Congress. This report summarizes what is known about the characteristics of CSOs and SSOs, the human health and environmental impacts of CSOs and SSO, and the resources spent and technologies used by municipalities to reduce the impacts of CSOs and SSOs. This report makes clear that EPA views CSOs and SSOs as threats to human health and the environment. This Report provides interested parties with a wealth of information on the impacts of sewer overflows and establishes a baseline of data for regulatory agencies to use in policy making related to the management of sewer collection systems. The Report to Congress is available at
