The city of Lewisville on Monday lifted a water boil notice that was issued early Sunday morning, meaning that Lewisville’s water supply is once again confirmed to be safe for consumption, according to a city news release.
Water customers who were affected by the boil water notice are urged to flush their home or business water system.
State-mandated water quality test results received early Monday afternoon showed that the water met or exceeded state and federal standards for water safety.
The boil water notice was initiated shortly after 2 a.m. Sunday after water service and water pressure suddenly plummeted for thousands of customers in central Lewisville earlier in the night. The cause was determined to be a 30-inch water main that had failed. Water service was restored within three hours, but the temporary widespread loss of water pressure triggered the boil water notice.
After a boil water notice is lifted, there are steps residents should take to ensure the safety of the water in their home:
- Flush all faucets: Run cold water at every tap in your house for at least 5 minutes. This includes sinks, tubs, and showers.
- Flush water heater: Run hot water from a faucet for 40 minutes.
- Discard old ice: Throw away any ice made while the boil water notice was in effect.
- Run an empty dishwasher cycle.
- Refrigerator water dispensers should be flushed according to manufacturer specifications.
- Flush automatic ice makers. Ice cubes should be emptied and run through a 24-hour cycle. Make three batches of ice and discard them.
- Run water softeners through a regeneration cycle.
- Get rid of water in humidifiers, CPAP machines, and other electric devices that collect water. Thoroughly clean all the machines before using them.
- Flush all toilets.
