One of my rentals had a shutoff valve that was leaking and I had to replace. I initially called the city, and I learned that I had two shutoff valves, one was the cities and the other was mine. Unfortunately, it was mine and it was really deep. Most of the bids were high because no one wanted to dig it up. My initial bids were about $800-1000. Luckily, my husband was once a manual laborer and just decided to dig the hole himself. He did it in a few hours and then a plumber was happy to come out and fix it that same day. I still paid $300 to have them fix it. If it is on the city's side, I believe they would fix it (I would leave out the part where you were the one that damaged it). I would start by calling the city, explaining your problem, and see if they will send someone out to look at it.
