LOS ANGELES -- January 8, 2014

As part of a continuous effort to upgrade and maintain Southern California’s
vast imported water delivery system, a large-diameter regional pipeline
serving Orange County communities from Yorba Linda to SanClemente will be
taken out of service for 11 days, beginning next Monday, Jan.13.

Officials from the Metropolitan Water District of Southern California joined
with the Municipal Water District of Orange County, the county’s regional
imported water provider, in forecasting no water service interruptions for
retail customers while a portion of Metropolitan’s 26-mile Allen-McColloch
Pipeline is shut down and inspected. The routine maintenance is part of
regional and local water providers’ ongoing investments in Southern
California’s water transmission and delivery systems.

Consumers and businesses are asked to check with their retail water provider
for potential impacts. A map of Orange County’s retail water providers, with

Debra C. Man, Metropolitan’s chief operating officer and assistant general
manager, said the district routinely schedules shutdowns of its facilities in
the winter and early spring, when temperatures usually are cooler and water
demands are lower, to conduct inspections and perform maintenance and upgrades
with the least impact on consumers.

“One of the biggest challenges to ensuring reliable deliveries is the need to
repair and upgrade aging facilities,” Man said, noting that more than 40
percent of the district’s water system is over 60 years old.

“Our water supply system is aging, and it will require increased investments
in repair and replacement in order to keep the system operating reliably,”
MWDOC Board President Joan C. Finnegan said. “In collaboration with
Metropolitan, MWDOC and the Family of Orange County Water Agencies are
committed to making these necessary investments in our water infrastructure to
ensure a reliable supply for current and future generations.”

Metropolitan’s 26-mile Allen-McColloch Pipeline extends from the district’s
Robert B. Diemer Water Treatment Plant in Yorba Linda to El Toro Reservoir in
Lake Forest, typically delivering about 100 million gallons of water a day for
Orange County residents. The line is the primary source of supplemental,
imported water to south county communities served by MWDOC, which relies on
Metropolitan supplies for about 50 percent of its water supplies.

During the outage, Metropolitan will shut down the pipeline early Jan. 13 and
drain an 11-mile portion of the high-pressure line for inspection. The
shutdown is scheduled until Jan. 23.

“Throughout the shutdown, residents and businesses are asked to use water as
efficiently as possible,” Finnegan said.

The Metropolitan Water District of Southern California is a cooperative of 26
cities and water agencies serving nearly 19million people in six counties.
The district imports water from the Colorado River and Northern California to
supplement local supplies, and helps its members to develop increased water
conservation, recycling, storage and other resource-management programs.
