At first, Amanda Fuller thought she was one of the lucky ones. Then the water stopped running.

As Texas started dipping into single-digit temperatures overnight Sunday, power companies began instituting blackouts across the state, but Fuller's home just outside Austin stayed warm and bright.

On Monday, though, as she was fixing a mid-morning a snack for her two children, ages 1 and 6, the water from the tap suddenly "went to a trickle within a few seconds and was gone,” she said. It turned out the freeze had caused several water mains to break as well as disrupting power to the city’s primary water treatment plant.
