Under this program, states receive annual capitalization grants to provide financial assistance (primarily subsidized loans) to public water systems for drinking water projects and other specified activities. Between FY1997 and FY2015, Congress had appropriated approximately $20 billion, and more than 12,400 projects had received assistance through the program.

The latest Environmental Protection Agency (EPA) survey of capital improvement needs indicates that public water systems need to invest $384.2 billion on infrastructure improvements over 20 years to ensure the provision of safe tap water. EPA reports that, although all of the identified projects promote the public health objectives of the SDWA, just $42.0 billion (10.9%) of reported needs are attributable to SDWA compliance. A study by the American Water Works Association projects that restoring aging infrastructure and expanding water systems to keep up with population growth would require a nationwide investment of at least $1 trillion through 2035……
