SACRAMENTO, Calif. (AP) – Water districts would have to create policies to punish residents who use too much water during droughts under a bill signed into law by Gov. Jerry Brown. Brown signed the bill requiring all districts to have policies for identifying and targeting heavy users during drought emergencies. That can include fines or a rate system that charges more for using large amounts of water. Democratic Sen. Jerry Hill of San Mateo says SB814 came after news reports that some residents used millions of gallons of excessive water despite the state’s ongoing drought. He says the bill will ensure that water guzzlers can’t keep using excessive amounts without penalty. The measure takes effect Jan. 1.
