SAN DIEGO (AP) — San Diego officials have instituted mandatory water restrictions amid California’s historic drought.

The City Council voted unanimously Monday to shift from Stage 1 “drought watch” conditions to Stage 2 “drought alert” restrictions.

U-T San Diego reports   the heightened measures are designed to reduce city water use by 20 percent and forestall deeper cuts in the future.

Under the new restrictions San Diegans must limit outdoor watering to three days a week, based on a schedule set by the city. Sprinklers will be limited to 10 minutes per day in warm months and just seven minutes per day in cool months.

Ornamental fountains will be shut off entirely, except for maintenance purposes.

Other restrictions limit car washing, construction-related water use and non-emergency access to fire hydrants.
