Clean Watersheds Needs Survey 2012 Update

1

What is CWNS

Assessment of capital costs needed to meet the Clean Water Act’s (CWA) water quality goals

Joint effort by EPA, States, & Local organizations

Conducted every 4 yearsNext data collection: 2012

Data is submitted by states via the CWNS Data Entry Portal (DEP)

Results in Report to Congress and publicly available data on the Internet

Clean Water Act Authority

CWA Sec. 516 excerpt defines EPA’s role:“The EPA Administrator, in cooperation with the States, …shall make (a)

a detailed estimate of the cost of carrying out the provisions of this Act”; (b) a detailed estimate…of the cost of construction of all needed publicly owned treatment works in all of the States and publicly owned treatment works in each of the States”

CWA Sec. 205(a) excerpt defines Congress’s role:“Allotments…shall be made only in accordance with a revised cost

estimate made and submitted to Congress in accordance with Sec. 516 of this Act and only after such revised cost estimate shall have been approved by law specifically enacted hereafter.”

Methodology

Inventory of Needs6

CWNS periodic inventory of existing and projected publicly owned wastewater treatment works (POTWs) and other water pollution control facilities in the United States

Not a census nor a sample

Enter data for as many facilities in the state as possible

Needs Definition

The unfunded capital costs -- as of January 1, 2012 -- of a project that addresses an existing or projected (within next 20 years) water quality or water quality related public health problem

CWNS 2008 Results

Highlights from CWNS 2008

Total reported wastewater and stormwater needs are $298.1 billion (January 2008 dollars) as of January 1, 2008. Total reported Nonpoint Source needs are $22.8 billion and Decentralized Wastewater Treatment System needs are $23.9 billion. Reported needs increased 17% from 2004 to 2008.Largest increases in needs are for secondary and advanced wastewater treatment and stormwater management.Seven states (DC, NJ, GU, NE, WV, NY, MD) reported per capita needs greater than $1,500. Eight states (NJ, CA, NY, FL, IL, OH, PA, TX) reported more than half of the total needs. 14,780 treatment facilities serve 226.4 million people. If all needs are met, 15,617 treatment facilities will serve 284.2 million people.
