Kansas 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). Kansas documented needs totaling $3.2 billion in 2008. This is a 33 percent increase from the $2.4 billion in needs documented in 2004.

All needs are in January 2008 dollars. ------- Kansas 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, 80% of Kansas residents received centralized wastewater treatment services at the secondary, advanced, or no discharge treatment level, compared to 24% in 1972.

Small Communities In Kansas, small community wastewater facilities serve 29% of the population and comprise 6% of total wastewater treatment and collection needs.
