HA! You are all so lucky!
I pay at least $35 a month for water before I use a drop for administrative fees, then it goes up from there. My lowest bill is usually about $48 a month, and when I have to water a lot in the winter (dry season), it's about $75 a month. I'd love to have a well dug, but I can't afford it.
That's one reason I'm thinking seriously about getting rid of all of the plants, and minimizing my landscape to native, drought tolerant plants.
