19th century working model for water in Texas?

19th century working model for water in Texas? (I am thinking of every neighborhood having a gas works in the19th century in order to get gaslight in your home at night.) I worked with a loan processor in Arizona in the mid nineties who had worked as a loan processor in Texas for a few years previously and she described the nightmare of paperwork attached to most mortgages that described the local Jim Crow method of attaching a water treatment plant and storage tank for every separate but not equal housing development built in the lone star state. The idea was that the rich developments had good water, cleaning and storage while the middle class ones got mediocre at best water treatment and storage. That there was no real state agency to test every one of these hundreds of "water authorities" dotting the de facto third world state of Texas. Just remembered looking at the news now, that thinking how hundreds of thousands in Texas still suck in that sh*thole country without a decent drop of water to drink still since the winter storm "Enron designed" electric grid failed.
