The last time I checked here it was around $800 deposit with about $40.00 of non-refundable water use credit for up to 13,000 gallons, after that is is just under $3.00 per 1000 gallons.
You go put down the deposit and tell them which fire hydrant you want it on and the city crew goes and connects it there. They don't want you handling it or moving it.
I made the mistake of getting the garden hose bib attachment, it was very slow like maybe 5gpm. When you have the 2" water meter it will fill up my 325 gallon tank in about 70 seconds, that is the meter I rent now when needed.
