Yes, Louisiana and Tennessee: https://www.theadvocate.com/acadiana/news/article_3ed2a512-7... https://wreg.com/news/watch-mlgw-provides-water-update/

The issue with water systems in Texas is thar we have them terribly networked. Water for Lockhart's towers come from the next town over who shut down their pumps. Lockhart blew a main which brought pressure below what was necessary to push water to the testing site for certification of being safe to drink..

On the Electricity front, Austin Energy screwed the pooch, because they had too much of their capacity tied up in "essential" service branches. So they had to isolate the few non-essential branches with high downtime to effectively shed load.

You can give Texas crap, but at least let it be accurate crap.

I assume the subtext is that the answer to my question is "no, other localities haven't lost water treatment in their winter outages" --- those outages apparently not being severe enough to impact water delivery.
