The city began flushing water lines the morning of July 20 and will begin testing multiple samples throughout dozens of Leander subdivisions July 21. City employees will be releasing water from hydrants and water valves throughout the city, the news release said.
The city is asking all city residents to “cease or restrict” all outdoor irrigation the week of July 20-24. On July 16, the city issued a Stage 2 water restriction, which regulates outdoor irrigation for the entire city.
"Peak water demands in the summer are largely caused by outdoor watering," city spokesperson Mike Neu said in the July 20 news release. "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 boil water notice was prompted by a power outage at Sandy Creek Water Treatment Plant, at 10400 Trails End Road in Leander, during the early morning of July 18. The outage, along with peak water demands over the past several days, created "sharp reductions in water volumes and pressures," according to the city.
The city recommends those in the affected area follow boil water instructions issued by the Centers for Disease Control and Prevention. The CDC recommends using bottled water for drinking and food preparation. If unavailable, tap water should be brought to a "full, rolling boil" for at least one minute. Once the water cools, it is safe to consume.
