The city went so far as to advise some residents near the city’s northeastern Sam Rayburn Tollway corridor to boil water before drinking after it reached substandard pressure levels.
Most Lewisville residents were not under a boil notice as of Thursday afternoon, the city said.
“Aggressive water conservation efforts are strongly encouraged for all Lewisville water customers,” the city of Lewisville said in a Feb. 18 statement. “There is no need for customers outside of the affected area to boil their water at this time.”
The nearby town of Flower Mound had not issued a boil notice, but asked residents to reduce water use by avoiding taking unnecessarily long showers or baths or running dishwasher or laundry machines.
“Our supply has not been severely impacted due to the careful planning of infrastructure improvements by the Town, as well as our wholesale providers planning efforts,” the town said in a Feb. 17 statement. “However, please continue to conserve water use, during this time.”
The city of Highland Village also declined to issue a boil notice, saying Feb. 18 that its water system was functioning “in a normal capacity.”
