What is EPA WaterSense?

Definition

EPA WaterSense is a voluntary US Environmental Protection Agency program that labels water-efficient products, new homes and programs meeting EPA criteria for efficiency and performance.

Who uses WaterSense

Manufacturers, retailers, homebuilders, irrigation professionals and utilities partner with the program. Commercial and institutional facilities use labeled fixtures and the WaterSense at Work best practices. Those facilities account for 17 percent of US public-supply water, per EPA WaterSense.

Key figures from EPA

  • Labeled products are certified to use at least 20 percent less water and perform as well as or better than regular models.
  • The program launched June 12, 2006, at the AWWA annual conference in San Antonio.
  • EPA reports cumulative savings of 11.2 trillion gallons of water through the end of 2025.
  • Leaks can account for more than 6 percent of a facility's water use, which no fixture label prevents.

Proving a fixture retrofit worked

A labeled fixture saves water only if the fixture is why use falls. Aqueduct normalizes water use per visitor and per square foot and sets a weather-normalized expected baseline before the retrofit, so the drop on each floor afterward is separated from changes in occupancy or season.

Questions

EPA WaterSense: common questions

EPA WaterSense is a partnership program run by the US Environmental Protection Agency that helps buyers find products and practices that save water without losing performance. It labels fixtures and irrigation products, certifies new homes and publishes guidance for commercial facilities. Aqueduct's view of water savings is on aQ WaterGuard.

No. WaterSense is a voluntary label, although some local codes and utility rebate programs reference WaterSense labeled products. Facilities usually meet it through purchasing choices and best practices rather than any reporting obligation.

Both are EPA labels. ENERGY STAR covers energy and WaterSense covers water, so facilities often use both when choosing replacement equipment. ENERGY STAR Portfolio Manager also tracks water, which links labeled fixture upgrades to measured building results.

WaterSense at Work is EPA's best practice guide for commercial and institutional water use. It recommends understanding where water goes, metering and sub-metering, and finding leaks, then improving fixtures, cooling and irrigation. Aqueduct supplies the metering and leak detection side of that approach.
