California water suppliers can begin warning and fining residential users for excessive water use during drought emergencies under a bill signed Monday by Gov. Jerry Brown. California’s more than 400 urban water suppliers will be tasked with creating a scheme that identifies water-guzzling water homeowners drought emergencies as well as implementing a system to hand out warnings and potential fines. Senate Bill 814 takes effect Jan. 1 and gives suppliers the authority to create new rate structures for high-volume water offenders. The law also authorizes fines of $500 per each 748 gallons used above the district’s maximum threshold.
