Oregon 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). Oregon documented needs totaling $4.9 billion in 2008. This is a 40 percent increase from the $3.5 billion in needs documented in 2004. Documented Needs in Oregon Needs (2008 Dollars, Millions) Type of Need 2004 2008 Percent Change Wastewater treatment $1,727 $1,977 14% Pipe repair and new pipes $702 $1,048 49% Recycled water distribution $6 $5 -17% Combined sewer overflow correction $989 $427 -57% Total Wastewater Treatment Needs $3,424 $3,457 1% Conveyance infrastructure n/a $263 n/a Treatment systems n/a $45 n/a Green infrastmcture n/a $10 n/a General stormwater management $73 $4 -94% Total Stormwater Management Needsb $73 $321 342% Agriculture (cropland) best management practices (BMPs) nra $16 n/a Agriculture (animals) BMPs nr <$0.5 n/a Silviculture (forestry) BMPs nr nr 0% Ground water protection: unknown source BMPs nr $5 n/a Marinas BMPs nr nr 0% Resource extraction BMPs nr nr 0% Brownfields remediation nr nr 0% Storage tank remediation nr nr 0% Sanitary landfills BMPs nr nr 0% Hydromodification (Water resource restoration and protection) nr $1,080 n/a Other estuary management activities0 n/a <$0.5 n/a Total Nonpoint Source Control NeedsM nr $1,102 n/a Total Decentralized Wastewater Treatment Needsb'd $1 nr -100% Total Needs $3,497 $4,880 40% aNot reported; Actual needs may be higher, since documenting these needs is difficult; °In 2004, Other Estuary Management Needs were reported under Separate State Estimates (SSEs); dNot included in Official Needs in the Report to Congress. County Needs ($M) None reported <5 5-50 > 50 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. ------- Oregon 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, 94% of Oregon residents received centralized wastewater treatment services at the secondary, advanced, or no discharge treatment level, compared to 53% in 1972.

Small Communities In Oregon, small community wastewater facilities serve 8% of the population and comprise 3% of total wastewater treatment and collection needs.
