The City of Woodway lifted its boil water advisory Friday.

The city issued the advisory Thursday morning after the Texas Commission on Environmental Quality found samples at two sites had low disinfection residuals.

A boil water advisory means all customers need to boil their water before drinking or washing with it. According to a press release from the city, children, seniors and people with weakened immune systems are vulnerable to harmful bacteria that could be in the water.

A spokesperson for the city said the TCEQ found the lower disinfection residuals during an audit they do every two to three years.

The city flushed the pipes to get the levels to acceptable amounts and sent samples away to be tested.

The advisory was canceled once they had results back that showed the water was safe.
