About 70 percent of water is used outdoors, so not watering lawns should help significantly in ensuring an adequate water supply, Barrett said. “If they would turn off sprinklers, for most people, that would be an automatic reduction of 70 percent,” Barrett said. The county already has received three reports of water-wasting, including someone washing a car and a condominium complex where the sprinklers were running. The number to call to report over-watering is 800-675-HELP. Recorded information on the shutdown is available at 800-218-0018. LANCASTER – Residents are responding to pleas to conserve water in the face of a treatment-plant shutdown but more needs to be done. On Sunday, the first day of a six-day closure of the Quartz Hill Water Treatment Plant, affected residents cut back water use by more than 25 percent, from 50 million gallons to 37 million gallons. “Fifty percent every day would be ideal for the whole week. Thirty percent everyday would get us through the period without running out of water,” Melinda Barrett, county water conservation program manager, said Monday. “If it gets warmer, or for any reason well production goes down, we need a cushion.” The shutdown of the water treatment plant through Friday will extremely limit water supplies for customers of Waterworks District No. 40, which relies on the plant to supply 60 percent of its water. The closure affects some 45,000 households in west Lancaster and west Palmdale. In the city of Palmdale, among District 40’s customers, officials say they were cutting irrigation. “The city has been doing our part to conserve water without losing significant amounts of turf,” public works director Leon Swain said. “We are shutting it down as much as we can.” To increase water supply, District 40 is getting an additional 3 million gallons a day during the six-day period from two other water agencies.160Want local news?Sign up for the Localist and stay informed Something went wrong.
