Well here we go again. Without notice the local municipal water company shut off the water supply without notice. Perhaps they forgot the mail. It works, sometimes.
So what happens. If perhaps you are in the middle of a bath or shower, gone. Cleaning clothes, stop. Toilets, let's just say we get the point. I guess the Government employees just feel they can do what they want when they want! DEFUND the Water Department! Better yet get a commercial operator. At least you can sue them!
Oops, I forgot, it is Putin's fault.
