Description

The Environmental Protection Agency's CWNS is required by Sections 205(a) and 516(b)(1) of the 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. The Clean Watersheds Needs Survey (CWNS) 2008 Report to Congress summarizes the results of EPA's 15th national survey of capital costs to address water quality or water quality related public health problems. The total wastewater and stormwater management needs for the nation are $298.1 billion as of January 1, 2008. This amount includes $192.2 billion for wastewater treatment plants, pipe repairs, and buying and installing new pipes; $63.6 billion for combined sewer overflow correction; and $42.3 billion for stormwater management. Small communities have documented needs of $22.7 billion.
