North Carolina Clean Watersheds Needs Survey 2008 The Clean Watersheds Needs Survey (CWNS) is a comprehensive assessment of needs1 to meet the water quality and water-related public health goals of the Clean Water Act (CWA). States and the U.S. Environmental Protection Agency (EPA) conduct the CWNS every four years under CWA Section 516 (b). North Carolina documented needs totaling $6.8 billion in 2008. This is an 11 percent increase from the $6.1 billion m needs documented in 2004.

County Needs (SM) None reported < 15 15-45 >45 1 Documented needs in the CWNS include the unfunded capital costs of projects as of January 1, 2008 that address a water quality or a water quality-related public health problem existing as of January 1, 2008, or expected to occur within the next 20 years; and meet the seven CWNS documentation criteria. All needs are in January 2008 dollars. ------- North Carolina Clean Watersheds Needs Survey 2008 Wastewater Treatment Facilities The enactment of the Clean Water Act (CWA) in 1972 resulted in dramatic improvements in the: Number of wastewater treatment plants. Percentage of the population served by wastewater treatment plants. Quality of effluent treatment from wastewater treatment facilities. In 2008, 47% of North Carolina residents received centralized wastewater treatment services at the secondary, advanced, or no discharge treatment level, compared to 33% in 1972.
