ONTARIO, Calif. -- A million inland Southern California
residents are being urged to conserve water while a major supply
pipeline undergoes repairs this month.
The Rialto Feeder pipeline, which provides Northern California
water to nine cities, will be shut down from April 16 to 24. The
shutdown will affect customers in Chino, Chino Hills, Claremont,
Fontana, La Verne, Montclair, Ontario, Rancho Cucamonga and Upland.
The announcement comes less than a week after another shutdown led
to a serious water shortage in Orange County. Residents did not
comply with pleas to cut water use until the Robert B. Diemer plant
in Yorba Linda, which was closed for upgrades, was reopened. Instead
water use was 30 percent above normal in some areas.
In the inland region, the Metropolitan Water District of Southern
California, which oversees the Rialto pipeline is making similar
pleas. Officials are telling customers to suspend outdoor watering
and cut back on other uses.
Water officials said they are very concerned about the condition
of the pipe, which showed no signs of damage when it was tested two
years ago. The damaged section of the 8-foot-diameter pipeline had
breaks in 85 stress wires, which are part of the pipe's support
The damage may have been caused by utility workers hitting the
pipe during a recent dig, officials said.
"We are perplexed that over the course of two years it can
disintegrate to a point that it needs serious repairs," said Bob
Muir, water district spokesman.
