Water: Critical Infrastructure and Key Resources Sector-Specific Plan as input to the National Infrastructure Protection Plan [open pdf - 3MB]
"There are approximately 160,000 public drinking water utilities and more than 16,000 wastewater utilities in the United States. About 84 percent of the U.S. population receives its potable water from these drinking water utilities and more than 75 percent has its sanitary sewage treated by these wastewater utilities. The drinking water and wastewater sector (Water Sector) is vulnerable to a variety of attacks, including contamination with deadly agents and physical and cyber attacks. If these attacks were to occur, the result could be large numbers of illnesses or casualties or denial of service that would also affect public health and economic vitality. Critical services such as firefighting and health care (hospitals), and other dependent and interdependent sectors such as energy, transportation, and food and agriculture, would suffer negative impacts from a denial of Water Sector service. In collaboration with the entire sector, a broad-based strategy to address security needs is being implemented. This work includes providing support to utilities by preparing vulnerability assessment and emergency response tools, providing technical and financial assistance, and exchanging information. Each section of the Water Sector-Specific Plan (SSP), as defined by the Department of Homeland Security (DHS) in its 2006 Sector-Specific Plan Guidance, is described below. This section of the SSP provides an overview of the Water Sector. Each drinking water or wastewater utility is considered an asset that comprises many components. The discussion includes an explanation of the Environmental Protection Agency's (EPA's) relationships, as the Sector-Specific Agency (SSA), with the private sector, State and local agencies, other Federal departments and agencies, and the public; a description of the relevant Water Sector authorities; a summary of its vision and goals; and explanation of its value proposition."
