dean Watersheds Needs Survey 2004
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
Sections 205(a) and 516 (b)(l).
Kansas reported needs totaling $2.1
billion in 2004. This is a thirty percent
increase from the $1.6 billion in needs
reported in 2000.

1 Costs in the CWNS are generally eligible for funding under the Clean Water Act State Revolving Fund (CWSRF). All needs are capital
needs except stormwater management needs, which include program development costs. The survey is a "snapshot" of data and needs;
needs are as of January 1, 2004, and all costs are in January 2004 dollars.

dean Watersheds Needs Survey 2004
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.
• Level of effluent treatment from wastewater treatment plants.
In 2004, 74% of Kansas residents received centralized wastewater treatment services at the secondary, greater
than secondary, or no discharge treatment level, compared to 24% in 1972.

a Number of facilities and population served if all needs documented in the CWNS 2004 are met.
b The remaining population is largely served by home and cluster sewage treatment systems.
(Number of facilities from Tables C-7 and C-8 of the CWNS 2004 Report to Congress)
What are treatment levels?
• Less than secondary treatment removes solids by filtration, sedimentation, and chemical coagulation.
• Secondary treatment removes most of the organic matter in wastewater using biological processes.
• Greater than secondary treatment removes additional organic matter, nitrogen, phosphorus, or toxics.
• No discharge facilities include facilities that reuse wastewater, discharge to an underground aquifer, or
dispose of wastewater via methods such as irrigation or evaporation.
The CWA goals of fishable, swimmable and drinkable waters require secondary or greater treatment.
Small communities often need additional assistance to meet CWA requirements, because they often lack
adequate financing, training, and economies of scale to efficiently manage and maintain wastewater treatment
systems.
In Kansas, small community wastewater
facilities serve 31% of the population and
comprise 14% of total wastewater treatment
and collection needs. EPA small community
support information is available at:
