The city of Pittsburgh has chronic problems with water. Repeated boil water advisories and in winter -- constant water main breaks. The problem is that the water system is antiquated. I don't know exactly how old the pipes are, but I would think after maybe a hundred years, they are in bad shape and should be replaced. But liker many liberal Democrat-run cities, Pittsburgh has its financial woes. What money the city does have is spent on frivolities like bicycle lanes and trails.
There was a movement to turn water service over to a private company, but it was shot down. Too bad. Where I live, the water service is contracted out. The water is a bit hard, but the water mains don't break every other day and we haven't had to boil our water. And my tap water tastes good. People Ii know who live in the city either buy bottled water or have a Brita or some such. Water out of the tap tastes awful.
