August 17, 2022-Rowland Water District (RWD) asks all customers to suspend outdoor watering from September 6-20, 2022, due to emergency repairs on a Metropolitan Water District pipeline that delivers imported water across Los Angeles County.

The Upper Feeder Pipeline, which brings water from the Colorado River Aqueduct to providers throughout the region, will be out of service for 15 days while crews work to fix a leak. During that time, customers are asked to stop watering outdoor plants and landscapes to preserve water supplies.

“While we have sufficient water storage to meet the needs of our customers during this period, we all need to work together to take this extra step to conserve water,” said Rowland Water District General Manager Tom Coleman. “The public’s cooperation will help ensure we extend supplies during this critical time.”

Metropolitan Water District of Southern California supplies Three Valleys Municipal Water District in Claremont, RWD’s wholesaler. The 36-mile Upper Feeder is an integral part of Metropolitan’s regional water system, and its shutdown has prompted conservation calls across the numerous cities and agencies it serves.

Customers should turn off their irrigation timers on the night of September 5 and turn them back on September 21. Grass may turn yellow during the temporary shutdown, but it will improve once regular watering resumes. Customers can also place mulch around plants and trees to help them retain moisture.

Those looking for additional water-saving ideas around the house can visit RWD’s conservation website, Customers are also encouraged to permanently reduce outdoor water use through Metropolitan Water District’s turf replacement program, which offers rebates of up to $10,000 to remove grass and install low-water landscaping instead.
