Foothill cities asked to reduce water use during 10-day treatment plant shutdown
Water utilities are asking residents of a large swath of the San Gabriel Valley to cut back on their water use starting Friday.
That's when a major water treatment plant will be shut down for 10 days.
Water will be in short supply from La Crescenta to Claremont from Friday to March 28 as crews upgrade the F.E. Weymouth Water Treatment Plant in La Verne.
The plant provides drinking water to 1.7 million people along the San Gabriel Valley foothills. The affected areas include Pasadena, La Cañada Flintridge, Diamond Bar and San Dimas.
The Metropolitan Water District of Southern California is asking customers to take water-saving measures, such as avoiding outdoor watering, car washing, filling swimming pools and delaying spring plantings.
The city of Pasadena, which relies on the plant for 60% of its drinking water, has declared its highest level of water emergency, a move that will ban most outdoor watering during the 10-day outage and penalize violators with fines up to $1,000, the Star-News reported.
While some communities will be able to make up for the shortage by drawing from groundwater supplies or reservoirs, those that rely more heavily on imported water from the treatment plant could run out of water unless they take conservation measures.
Most of those communities, including Altadena, Rowland Heights and Walnut, are enacting their own voluntary or mandatory water-use restrictions to ensure their water supplies do not run dry.
