        to identify and promote water-efficient products, buildings and 
        building landscapes, facilities, processes, and services that, 
        through voluntary labeling of, or other forms of communications 
        regarding, products, buildings and building landscapes, 
        facilities, processes, and services while meeting strict 
        performance criteria, sensibly--

                generations.
            ``(2) Inclusions.--The Administrator of the Environmental 
        Protection Agency (referred to in this section as the 
        `Administrator') shall, consistent with this section, identify

                    ``(B) the procedure, including the methods and 
                means, and criteria by which an item may be certified 
                to display the WaterSense label, minimizing unintended 
                or negative impacts to wastewater treatment works, 
                recycled water quality, or water quality in receiving 
                water;

                    ``(A) establishing and maintaining feasible 
                performance criteria so that products, buildings and 
                building landscapes, facilities, processes, and 
                services labeled with the WaterSense label perform as 
                well or better than less water-efficient counterparts;

facilities, processes, and services.
    ``(d) Distinction of Authorities.--In setting or maintaining

    (b) Conforming Amendment.--The table of contents for the Energy 
Policy and Conservation Act (42 U.S.C. prec. 6201) is amended by 
inserting after the item relating to section 324A the following:

``Sec. 324B. WaterSense.''.
Water Efficiency Improvement Act of 2017 This bill amends the Energy Policy and Conservation Act to codify the WaterSense Program of the Environmental Protection Agency (EPA) that allows water-efficient products, buildings, landscapes, facilities, processes, and services to bear a "WaterSense" label.  The EPA must establish certification criteria for the WaterSense label, enhance public awareness regarding the label, preserve the label's integrity, and review, and if appropriate, revise the WaterSense label requirements. To the maximum extent practicable and no less than annually, the EPA must estimate and publish the aggregate production, aggregate market penetration, and savings of water, energy, and capital costs of water, wastewater, and stormwater attributable to the use of WaterSense-labeled products, buildings and building landscapes, facilities, processes, and services.
