City of Sacramento water conservation representative Steven Upton walks back to his truck after delivering a citation to a Sacramento, California home where sprinklers are running on a mandatory “no watering” day, in this August 15, 2014 file photo. About a hundred years ago, when urban water systems were being developed throughout the state, the city of Sacramento wrote protections from metering into its charter, vowing that residents would always have the right to use as much water as they needed. But on Tuesday, the state's top water regulators released a framework for enforcing California's first statewide mandatory restrictions on urban water use – cuts of 25 percent for non-agricultural users ordered last week by Democratic Governor Jerry Brown as a devastating drought enters its fourth year.
