An initiative that encourages consumers to use water-efficient technologies has helped US consumers save $32.6 billion (£22bn) on energy and water bills.
Launched 10 years ago by the Environmental Protection Agency (EPA), WaterSense has also saved 1.5 trillion gallons of water – more than what is needed to supply all homes in California for a year.
More than 1,700 utilities, local governments, manufacturers, retailers, distributors and builders have partnered with EPA to develop and promote water-efficient products and programmes.
WaterSense-labelled products are independently certified to use at least 20% less water and also save energy associated with treating, pumping and heating water.
They have saved the energy equal to the amount used to power 19.4 million homes for a year while preventing 78 million metric tons of emissions, according to EPA.
