New Jersey
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). New Jersey
documented needs totaling $36.6
billion in 2008. This is a 137 percent
increase from the $15.5 billion in needs
documented in 2004.

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.

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, 91% of New Jersey residents received centralized wastewater treatment services at the
secondary, advanced, or no discharge treatment level, compared to 57% in 1972.
