Sacramento's newest watering restriction goes into effect Sunday.

Coinciding with the end of daylight-saving time on Sunday, residents and businesses will be limited to irrigating once a week, according to a city Department of Utilities press release late Thursday afternoon.

Residents and businesses can't water on weekdays under the restriction. Those with odd-numbered addresses may water on Saturdays only and even-numbered addresses may water on Sundays.

The Sacramento City Council approved the restriction in May as part of an irrigation ordinance restricting summer watering to certain hours every other day. California is in its third year of drought.

Watering restrictions will return to every other day at the start of daylight-saving time next year, she said Jessica Hess, utilities department spokeswoman.

"When the weather gets cooler, they really don't need to water more than once a week," Hess said. "Or even not at all when we're having rain."

The council will consider changing the ordinance to restrict watering between 10 a.m. and 7 p.m. during daylight-saving time, lift limits for drip irrigation and make other adjustments at its Nov. 3 meeting, according to Hess. Landscape watering is currently banned between 10 a.m. and 6 p.m.
