This is the Congressional Budget Office Cost Estimate as ordered reported by the Senate Committee on Energy and Natural Resources on November 19, 2019. From the Bill Summary: "S. 2799 would direct the Department of Energy (DOE) to establish a smart energy and water efficiency pilot program. Under that program, DOE would award grants to eligible entities for implementing technology-based solutions to improve the efficiency of water systems. The bill would require DOE to use unobligated funds that are available to the department to finance the program. The bill also would direct DOE and the Department of the Interior (DOI) to establish a joint office and an interagency committee to develop a strategic plan and coordinate research, development, and demonstration projects on energy and water issues."
