When Texas’ statewide deep freeze left millions without power, one in four Houstonians experienced burst or leaking pipes, according to new data published March 2 by Houston Public Works.

The data also shows that 50,000 single-family homes lost some, if not all, water flow during the event and that 400 apartment complexes experienced leaks.

Houston Public Works fielded 11,000 calls related to water issues during and after the weather event.

Some two weeks after the event, some residents called into Houston City Council’s public comment session March 2 to report that their apartment complexes are still without water. Residents without water are asked to call 311.

Residents who have faced damage, regardless of whether it has been repaired, can report it to the Houston Office of Emergency Management. The reports will help the city of Houston qualify for federal disaster recovery funds.
