It may not seem like it, but it's not a major event, lol... Usually when there is a boil order it's because a major supply line has burst and the possibility that contaminated water may have entered the closed system on a wide scale. Isolated issues like this may just require the lines being flushed until clear. Using a carbon block wouldn't be a bad idea...
In my area, I wouldn't have to foot the bill if the city did the work. If it were my issue, the city wouldn't even do the work. I would have to contact a plumber and pay them directly. Hopefully yours is the same!
