LEANDER, Texas (KXAN) — A boil water notice has been issued until at least Friday in Leander, officials say.

According to the city, a significant amount of Leander water customers are affected. The approximate area of impact stretches from the boundaries east of the Travisso neighborhood and west of Toll 183A, including the Bryson neighborhood.

In order to get the city’s water supply back to normal, officials are asking residents to stop or significantly cut back on all outdoor watering.

“Peak water demands in the summer are largely caused by outdoor watering,” Pflugerville Public Information Officer Mike Neu said. “If affected customers can stop irrigation over the next few days, and all residents can limit outdoor watering, our water system will recover much faster.”

The city of Leander released this map of approximate areas where the boil water notice is in effect until further notice.

City leaders posted the boil water alert at 7 a.m. Saturday, after an early morning power failure at the Sandy Creek Water Treatment Plant. The city says that plus peak water demands over the past few days triggered a reduction in water volume and pressure.

Power to the water plant has been restored, however the city says it may take several days for normal water pressure to recover.
