EPA: $384 Billion in Drinking Water Infrastructure Needs Through 2030

EPA released results of a new survey documenting $384 billion in needed capital investment for U.S. drinking water infrastructure through 2030. This total includes capital costs for compliance with Safe Drinking Water Act (SDWA) regulations as well as continued provision of safe drinking water to 297 million Americans. The 2011 Drinking Water Infrastructure Needs Survey and Assessment (DWINSA) estimates investments needed over the next two decades. The national total of $384 billion includes the needs of 73,400 public water supply systems in the United States, including American Indian and Alaska Native Village systems. The new estimate is based on information collected in 2011 and is similar to needs estimates published in 2007 and 2003, when adjusted for inflation. EPA said that just $42 billion of the total, or 11 percent, is directly related to maintaining compliance with the Safe Drinking Water Act (SDWA), with $37.1 billion needed for existing regulations and $4.9 billion is for compliance with proposed and recently promulgated regulations. The majority of the regulatory cost is associated with microbial contaminants. EPA said the 2011 DWINSA has a statistical confidence level of 95 percent.
