P.S. Make sure you can determine how much they are going to charge you for that "city water".
Many systems have gone to tiered pricing schemes. Normal volumes of water for household usage are very cheap. However, if you use 10 times that amount of water, your bill might go up 30x.
If you used a 1,000 times your normal amount, it might be WAY more expensive than 1,000 times your normal monthly water bill.
