2012-13 Shutdown Season


Weymouth Shutdown March 2011

Preparations for new ozone facilities at Metropolitan's oldest water treatment plant and upgrades and repairs to its regional Upper Feeder pipeline top the list of projects planned by the district during its 2012-13 shutdown season.

Each year, between October and April, Metropolitan takes various facilities out of service temporarily to perform maintenance and service upgrades, as part of its ongoing efforts to ensure water supply reliability.

The district's ability to reliably store, treat and deliver water throughout its six-county service area requires treatment plants, pipelines and other essential facilities—some in operation for more than 70 years—to be shut down for upkeep and improvements.


Weymouth Shutdown March 2011

This season, Metropolitan has 31 shutdowns planned. The shutdowns range in length from one day for the Palos Verdes Feeder to replace a valve to 32 days for a small power plant in Orange County for maintenance and repair.

February will be particularly busy. Metropolitan is scheduled to take its F.E. Weymouth Water Treatment Plant in La Verne out of service for four days later in the month to further prepare the 71-year-old plant for an upgrade to ozone water treatment.  Also in February, Metropolitan is shutting down, for eight days, 27 miles of its Upper Feeder pipeline for refurbishments. That portion of the large-diameter pipeline supplies treated water to foothill cities and communities in eastern Los Angeles County, from Glendale to Glendora.


Construction at Shutdown

Another 25-day shutdown of Metropolitan's Colorado River Aqueduct (CRA) is planned as part of the district's 13-year overhaul of the 242-mile aqueduct.

The district routinely schedules shutdowns in the winter and early spring, when temperatures are usually cooler and demands are lower, to complete inspections and perform maintenance and upgrades with the least impact on customers.


Foothill Feeder Shutdown

Most local agencies affected by a shutdown have groundwater, reservoir supplies and other sources to meet retail demands during the outage. However, on occasion—particularly when Metropolitan takes a regional water treatment plant or a large pipeline out of service—some local agencies need consumers to pitch in and conserve water to stretch supplies. Voluntary conservation by consumers and businesses, and collaboration among water agencies, offer safeguards so residents and businesses have adequate water during a shutdown.

While this year's shutdown season is underway, the district is already preparing for future repairs and upgrades.  Depending on the size and complexity of a facility, Metropolitan and its member agencies and retailers spend up to two years coordinating and arranging various facility shutdowns.
