Welcome to the
2011 Drinking Water Infrastructure Needs Survey and Assessment Website
.
The
1996 Safe Drinking Water Act Amendments
directed the EPA to conduct a survey of the infrastructure needs of public water systems every four years. The surveys collect data from water systems nationwide that are eligible to receive Drinking Water State Revolving Fund (SRF) monies regarding their 20-year capital improvement needs to ensure the continued provision of safe drinking water. Data from these surveys are used to develop formulas used by Congress to allot Drinking Water State Revolving Fund grants to each state based on their need. The first Report to Congress was published in 1997 and subsequent reports were published in 2001, 2005, and 2009.
