EPA WaterSense

A National Partnership to Save Water and Protect the Environment

WaterSenseWaterSense, is a voluntary partnership program sponsored by the U.S. Environmental Protection Agency (EPA), designed to make it easy for Americans to save water and protect the environment by choosing water efficient products and services. Items that meet WaterSense specifications must be independently tested and/or certified, and only then can they carry the WaterSense label. Many WaterSense products and service providers are now available and the EPA is actively developing new specifications to expand the WaterSense family. 

H2Otel Challenge:

Launched on February 5, 2014, the WaterSense H2Otel Challenge encourages hotels to assess water use, learn about the best management practices (see below) for reducing water in hotels, and track their results.  WaterSense and its partners will challenge hotels to learn about the best management practices and provide hotels with the tools to "ACT".  Learn more here. 

Best Management Practices:

WaterSense has developed WaterSense at Work, a compilation of water-efficiency best management practices, to help commercial and institutional facilities understand and better manage their water use, help facilities establish an effective water management program and identify projects and practices that can reduce facility water use. Learn more here. 

WaterSense Product Certification System (Version 2.0):

As part of the ongoing effort to improve the WaterSense program, EPA released the WaterSense Product Certification System, Version 2.0 in September 2011.  EPA revised the product certification system to accommodate growth and expansion of the WaterSense program while balancing the cost of certification with the program need to maintain the integrity of the WaterSense label.  As of November 3, 2011, WaterSense transitioned to a new product notification process, in which the licensed certifying bodies directly notify EPA of which products have earned the WaterSense label.  Manufacturers no longer provide this information directly to EPA.  For more information, go to the WaterSense Product Certification page. 

Notification of Intent:

Issued to Develop a Draft Specification for Flushometer-Valve Toilets  

To help commercial facilities become more water-efficient, WaterSense has issued its Notice of Intent (NOI) to develop a specification for flushometer-valve toilets. Many of the older flushometer-valve toilets currently installed use 3.5 gallons per flush (gpf)—far more water than the federal standard of 1.6 gpf. With many of these models reaching the end of their useful life, replacing them with more efficient models could result in significant water savings.  Interested parties are invited to provide written comments on WaterSense’s NOI to label flushometer-valve toilets. Please send any comments or suggestions to watersense-products@erg.com.

Issued to Develop a Draft Specification for Soil-Moisture-Based Control Technologies   

To help increase water efficiency outdoors, WaterSense has issued its Notice of Intent to develop a specification for soil moisture–based control technologies, which will compliment the existing weather-based irrigation controller specification.  Soil moisture-based control technologies water plants based on their needs by measuring the amount of moisture in the soil and tailoring irrigation schedules accordingly.  Studies suggest that soil moisture sensors can result in water savings of at least 20 percent, potentially saving millions of gallons of water across the country.  Soil moisture-based control technologies that earn the WaterSense label will take the guesswork out of watering and help improve irrigation system efficiency.  Interested parties are invited to provide written comments on WaterSense’s Notice of Intent to label soil moisture-based control technologies. Please send any comments or suggestions to watersense-products@erg.com Please contact the WaterSense Helpline at watersense@epa.gov or (866) WTR–SENS (987–7367) if you are submitting any data that need to be handled as confidential business information (CBI). Note: All comments, except data claimed as CBI, become a part of the public record. 

Issued for Development a Draft Specification for Water-Efficient, High-Performing Cation Exchange Water Softeners 

EPA's WaterSense wishing to capitalize on recent improvements in water softening technology, has issued a Notification of Intent (NOI) to develop a draft specification for water-efficient, high-performing cation exchange water softeners.  The technology improvements demonstrate that there is great potential for water savings.  The NOI outlines the efficiency and performance criteria WaterSense is working to define and the technical issues that still need to be resolved related to this product category.  At this time, WaterSense is not proceeding with the development of a draft specification for water softeners.  Learn more here
