Millions of Americans are under boil-water advisories in north and central Texas as the recent winter storms have triggered a water crisis in the state. The deep freeze has left many in the region without water or electricity altogether, triggering a major disaster declaration from President Joe Biden, who is requesting federal funding to help Texans.

As of Feb. 21, there were still more than 1,200 public water systems reporting disruptions in service, affecting more than a third of the state, according to CNN.

Power outages, ruptured pipes and leaking reservoirs are all contributing factors in the widespread outages, and public utilities continue to work to restore water service around the state.

The public side is only half the battle, however, as citizens have also experienced widespread issues with residential plumbing which froze in unheated homes. As pipes continue to thaw, more Texans will likely discover leaking water pipes in their homes.

Houston Mayer Sylvester Turner told CNN his city will need a huge influx of plumbing materials in the coming weeks. “We have a number of licensed plumbers but could use even more,” Turner said. “But the main thing is that even when plumbers are going out, it is very difficult to find the necessary materials and supplies.”

Meanwhile, the Texas National Guard, U.S. Department of Defense and Federal Emergency Management Agency have been distributing bottled water throughout the state.

Texas Gov. Greg Abbott said during a news conference that uninsured residents with burst pipes may qualify for reimbursement from FEMA. “We have had FEMA assistance granted by the federal government, and a part of that is individual assistance that will assist individuals whose homes or apartments have been harmed because of the winter storm,” he said.
