C A L I F O R N I A E N E R G Y C O M M I S S I O N Toilets, Urinals, and Faucets On April 8, 2015, the Commission adopted water- efficiency standards for toilets, urinals, and faucets. Once in effect, these standards are estimated to save annually: –10.3 billion gallons of water, –30.6 million therms (Mtherm) of natural gas, and –218 gigawatt hours (GWh) of electricity. Over ten years, the standards will save an estimated 730 billion gallons of water.
