* The Environmental Protection Agency's Clean Water Needs Survey (CWNS) is required by Sections 205(a) and 516(b)(1) of the Clean Water Act (CWA). The CWNS is a summary of the estimated capital costs for water quality projects and other activities eligible for SRF support as authorized by the 1987 CWA Amendments. These activities include both facilities and certain water quality program elements. Activities include the planning, design, and construction of publicly owned wastewater collection and treatment systems and projects controlling CSOs, SW, and NPS pollutants. Other eligible water quality program elements are those that involve one-time expenditures supporting the CWA goals, such as program development and implementation. Ongoing expenditures, such as operation and maintenance (O&M) costs, are not included. The 1996 CWNS, a joint effort of the States and EPA, is the twelfth such survey since the CWA was enacted in 1972. * Primary Treatment

The first stage of wastewater treatment, including removal of floating debris and solids by screening and sedimentation.

Wastewater

Dissolved or suspended waterborne waste material. Sanitary or domestic wastewater refers to liquid material collected from residences, offices, and institutions. Industrial wastewater refers to wastewater from manufacturing facilities. Municipal wastewater is a general term applied to any liquid treated in a municipal treatment facility and usually includes a mixture of sanitary and pretreated industrial wastes.

Wastewater Infrastructure

The pipes and appurtenances for the collection, treatment, and disposal of sewage in a community. The level of treatment will depend on the size of the community, the type of discharge, and/or the designated use of the receiving water.
