United States Environmental Protection Agency WaterSense is a voluntary labeling program administered by the United States Environmental Protection Agency to promote water-efficient products, homes, and services. It aims to reduce water use, enhance consumer awareness, and encourage innovation among manufacturers, builders, and utilities. The program leverages partnerships with industry, non‑profit organizations, and state agencies to set performance criteria, certify products, and influence market transformation in indoor and outdoor water use sectors.
WaterSense operates as a partnership and certification initiative that identifies products, programs, and practices meeting water efficiency and performance criteria. It targets plumbing fixtures such as faucet aerators, toilets, and showerheads, as well as irrigation systems, new homes, and certification providers. The program interfaces with stakeholders including the United States Department of Energy, American Water Works Association, U.S. Green Building Council, National Association of Home Builders, and ENERGY STAR to coordinate labeling and efficiency metrics. WaterSense labeling signals to consumers, utilities, and governments that a product or service meets US EPA‑endorsed water efficiency and performance standards.
WaterSense was launched in 2006 following policy discussions involving the 2005 Energy Policy Act, water utility stakeholders, and environmental organizations such as the Natural Resources Defense Council and The Nature Conservancy. Early development included technical input from the American Society of Civil Engineers and the Water Research Foundation. The program evolved alongside federal initiatives such as ENERGY STAR and state programs in California, Texas, and Florida that sought to address drought resilience and infrastructure stress. WaterSense criteria have been revised periodically with contributions from the National Institute of Standards and Technology, industry trade groups like the Plumbing Manufacturers International and advocacy groups including Sierra Club and Environmental Defense Fund.
WaterSense certifies products, new home designs, and irrigation professionals through third‑party testing and labeling. Product manufacturers submit models for laboratory testing accredited by bodies such as the American National Standards Institute and International Organization for Standardization‑aligned labs, with verification by independent certifiers like UL Solutions and Intertek. New home certification requires on‑site inspection and verification by certifying organizations such as the Building Performance Institute or programs administered by state energy offices. The label is used by utilities including Metropolitan Water District of Southern California, Denver Water, and New York City Department of Environmental Protection for rebate and incentive programs.
WaterSense establishes performance thresholds and testing protocols for efficiency and efficacy. Criteria address flow rates, flush volumes, delivery pressures, and fixture performance under varied conditions, referencing standards developed by ASME A112, ASTM International, and the Uniform Plumbing Code. Irrigation specifications involve evapotranspiration‑based scheduling and use testing protocols from the Irrigation Association. The program coordinates with federal regulations such as the Energy Policy Act of 1992 and federal appliance standards when applicable and adapts to emerging technologies including smart controllers, weather sensors, and low‑flow aeration technologies promoted by laboratories at National Renewable Energy Laboratory.
WaterSense aims to reduce potable water consumption and associated energy use across residential and commercial sectors. The label influences procurement policies for municipal buyers like the General Services Administration and informs green building rating systems such as LEED administered by the U.S. Green Building Council. Market adoption has affected product lines from manufacturers such as Kohler Co., Moen Incorporated, Delta Faucet Company, and building programs from builders affiliated with the National Association of Home Builders. Utilities and municipalities use WaterSense qualifications to structure rebate programs and demand‑side management, similar to initiatives by Southern Nevada Water Authority and Seattle Public Utilities.
WaterSense collaborates with federal agencies, state water boards, industry associations, and conservation NGOs. Key partners have included the United States Department of the Interior for water conservation in public lands, state entities such as the California State Water Resources Control Board, and non‑profits like Alliance for Water Efficiency. Outreach employs campaigns alongside American Water Works Association conferences, trade shows like International Builders' Show, and publications from academic institutions including Harvard University and Stanford University that study urban water efficiency. The program also engages with standards organizations such as IEEE when addressing smart device interoperability.
Critiques of WaterSense encompass debates over stringency of criteria, enforcement mechanisms, and market effects. Some plumbing industry stakeholders and water utilities have argued for tighter standards, referencing analyses from the Government Accountability Office and researchers at the Brookings Institution and Resources for the Future. Concerns include reliance on voluntary adoption rather than mandatory regulation, potential conflicts with manufacturers' product lines represented by bodies like Plumbing Manufacturers International, and disputes over test methods involving American Society of Mechanical Engineers standards. Environmental groups such as Food & Water Watch and journalists from outlets like The New York Times have scrutinized labeling efficacy and claims about water savings, while local water districts in drought‑prone regions including Santa Clara Valley Water District have pressed for broader conservation measures beyond labeled products.
