Austin Water deemed winter climate a low danger to the town’s water provide earlier than Winter Storm Uri, the utility advised the Water Oversight Committee on Wednesday.

“Sadly, on this occasion, we didn’t have data to point that excessive winter climate was a danger for us,” mentioned Anna Bryan-Borja, an assistant director at Austin Water. “We now have weathered different winter storms previously, they usually haven’t had a major impression on our infrastructure.”
The town’s water system failed catastrophically during the storm. 1000’s of Austinites misplaced water for a number of days as a consequence of extra water utilization demand from burst pipes and mains and dripping taps. The leaks induced the town to challenge a boil-water discover and drinkable water needed to be introduced in from out of state.
In mild of this catastrophe, Metropolis Council members questioned why winter climate wasn’t seen as a danger. “We don’t appear to have deliberate as a metropolis with respect to our infrastructure and different issues for chilly climate,” Council Member Alison Alter mentioned. “I’d like to higher perceive why not?”
Bryan-Borja defined how the utility assesses dangers. “After we do danger planning,” she mentioned, “we take a look at the entire spectrum of dangers … however the objects which can be chosen for particular corrective motion are these objects which have a really excessive chance of coming to fruition.” Such corrective actions may embrace coaching or infrastructure funding.
“I don’t need to depart you with the impression that we’re fully unprepared for chilly climate,” Bryan-Borja emphasised. “However by way of a danger evaluation, for making ready for emergencies, (winter climate) didn’t rise to that degree.”
Citywide climate resilience plans didn’t point out chilly climate as a menace in any respect. As a substitute they targeted on “the danger of accelerating temperatures, and known as out the truth that Austin is understood for gentle winters,” Bryan-Borja mentioned.
Winter climate was additionally not included in Austin Water’s federally mandated danger and resilience evaluation. The best-priority threats for this plan, in keeping with Bryan-Borja, included inclement climate on the whole, floods, droughts and excessive warmth. The Environmental Safety Company signed off on the town’s evaluation.
Although the EPA requires up to date plans each 5 years, Austin Water plans to take action each two years to higher reply to altering dangers. “Transferring ahead,” Bryan-Borja mentioned, “Austin Water will alter our responses to satisfy the threats which can be evolving and our danger evaluation will embrace excessive winter climate.”
By means of these planning efforts, the utility intends to search out the particular fixes to make sure the water provide doesn’t fail in future winter storms.
