That’s what happens when you fail to maintain things for 30+ years, syphon off all the money for shareholders, and then cry poverty when the government decides that just flushing everyone’s shit into the river isn’t an acceptable way to deal with it.
Tighten the rules further and nationalise any company that can’t keep up. Should never have been privatised in the first place. I, a fairly normal person, cannot pick and choose which company provides my water like I can with electricity, gas and internet. So what’s the point of having a company run it?
