Water "Avarya"

I wrote about not having warm water in summer times as municipality is busy with water pipes maintenance. One would think that after three months of a maintenance period water pipes would be in excellent condition to supply water for the rest of the year. Unfortunately that is not the case.
Every time I see this yellow truck close to my home I know there will be no water for some time.
For those who does not know some Russian the text on the truck says "avarya vodoprovovodu" and in russian "avarya" means "accident".
When I started Russian classes with Natalia - my lovely Russian teacher in Moscow - this was the first word she thought me. In my first Russian class she asked me about Russian words I know. As "avarya" was not in my vocabulary, she thought me this word saying that this is one of most important words in everyday life. And indeed it is as avarya is used when: there is a car accident, there is no water or electricity, heating does not work, lift is out of order, etc. Here accidents are abundant.
