In this photo taken Tuesday, March 11, 2014, Steve Upton, an inspector for the water conservation unit for the Sacramento Utilities department, checks on a leaking small valve pipe, near a commercial building, that could cause as much of 100 gallons a month to be lost, while making his rounds in Sacramento, Calif. At least 45 water agencies throughout California have imposed mandatory restrictions on water use as their supplies run dangerously low. In the first three months of the year, Sacramento has received 3,245 water waste complaints with officials issuing 350 violations in a recent two-day sweep to catch people watering their landscaping on the wrong days.(AP Photo/Rich Pedroncelli)
