More than 14.9 million people have been impacted by disruptions across more than 1,300 public water systems, Tiffany Young, spokesperson for the Texas Commission on Environmental Quality, told CNN in an email Friday evening.
Water systems in 159 counties have also been impacted in Texas, Young said.
Some background: Authorities warned overnight that, while power has been largely restored, water supplies remain especially low.
Some hospitals have been operating without water service. As of Thursday afternoon, that included Houston Methodist West and Houston Methodist Baytown hospitals, said hospital system representative Gale Smith.
"They have been creative, from trucking water in for consumption to collecting rainwater to use for flushing toilets," Smith said. Both facilities, Smith said, were "still effectively caring for our patients."
In Austin alone, the state capital's water supply lost 325 million gallons due to burst pipes, Austin Water Director Greg Meszaros said during a news conference Thursday.
In Houston, the fire department received almost 5,000 reports of broken pipes, Mayor Sylvester Turner said Friday at a water distribution event.
