SAN DIEGO -- Water use was down 9.5 percent citywide in October, compared to the same month last year, San Diego Mayor Jerry Sanders announced Wednesday.

Overall, San Diego residents have cut their water use by about 13 percent since the city imposed mandatory restrictions in June, according to the mayor's office.

Sanders applauded San Diegans for heading the call to conserve water, but cautioned that now is not the time to become complacent.

"Make no mistake, all of us need to continue our vigilance in the months ahead," Sanders said. "Now is not the time for complacency."

"I know that a lot of people think we are entering into the winter season so we don't need to worry about water usage and that's simply not true," he said.

Following the declaration of a "level 2" drought by the City Council early this summer, mandatory water restrictions were imposed in San Diego.

Residents are only allowed to water their lawns and landscaping three days a week, on designated days, before 10 a.m. or after 4 p.m., for seven minutes at a time.

Most people are complying, Sanders said. However, there have been 3,100 complaints about scofflaws, and five water customers have been given warning citations. So far, nobody has been fined.
