Clean Watersheds Needs Survey
The U.S. Environmental Protection Agency is mandated by Congress to perform a comprehensive assessment of capital costs to meet the water quality goals of the Clean Water Act. Examples of capital projects include wastewater projects for publicly-owned systems, stormwater management facilities and nonpoint source pollution control projects. A needs survey is conducted by all states and territories on a periodic schedule as determined by EPA.
The data collection period for the 2022 Clean Watershed Needs Survey (CWNS) ended on April 28, 2023. For more information regarding the CWNS, visit the U.S. EPA's CWNS webpage.
