Overview
WaterSense is a program by the U.S. Environmental Protection Agency (EPA) aimed at promoting water efficiency. Launched in 2006, the program certifies homes and buildings that meet high water-saving standards. To receive a WaterSense label, properties must use 20% less water than average homes and incorporate water-efficient fixtures and appliances.
Since its inception, WaterSense has helped save over 5.3 trillion gallons of water and $108 billion in utility bills. Key partners include home builders, utility companies, and product manufacturers. Major builders like KB Home and Meritage Homes often participate in the program. Certification extends beyond homes to buildings and businesses, encouraging water-efficient practices across various sectors. The program is praised for its pragmatic approach to resource conservation, contributing to both environmental protection and significant consumer savings.
Requirements & Verification
Evidence Requirements
Builders must work with an EPA-recognized Home Certification Organization (HCO) and a trained Verifier who conducts on-site inspections and documentation review. The home must meet the WaterSense Homes Specification, which requires water-efficient indoor fixtures (toilets, faucets, showerheads), efficient irrigation systems, and overall water use at least 20% below a baseline home. Third-party verification of installed products and systems is required before the label is awarded.
Prerequisites
Assessment Process
Certification is conducted by EPA-recognized Home Certification Organizations (HCOs) and trained Verifiers. A Verifier performs an on-site inspection of the completed home to confirm that all water-efficient fixtures, appliances, and irrigation systems meet the WaterSense Homes Specification. Documentation of installed products and field verification of performance are required. There is no written exam; certification is based entirely on third-party field verification and documentation review.
Renewal & Compliance
WaterSense labeled homes are certified on a per-home basis at the time of construction. There is no ongoing renewal requirement for individual homes once certified. Builders and HCOs who participate in the program must maintain their partnership agreements with EPA and comply with updated specifications as they are released.

Consider Alternatives If...
Builders or developers focused solely on energy efficiency may find programs like ENERGY STAR or LEED more comprehensive for their goals. Those seeking a single certification covering all sustainability dimensions (energy, materials, indoor air quality) should consider a broader green building standard instead.
