Clean Watersheds Needs Survey (CWNS) – 2000 Report and Data
The CWNS 2000 Report to Congress summarizes the results of EPA's thirteenth national survey. Section 516 of the CWA requires EPA to periodically report to Congress state and national estimates and comprehensive studies on the costs for compliance with the CWA.
This report provides an analysis of the capital investment necessary to meet the nation's wastewater treatment and collection system needs and, to a limited extend, its municipal stormwater management program needs. EPA has also elected to include nonpoint source pollution control needs.
