Mine is way more than it should be. It runs from $80 to $100 a month (includes sewer but nothing else). That's with two teens and one adult. We run the dishwasher between 2 and 3 times a week. My big users are laundry and showers. The kids will fairly often go through a couple of outfits a day, and DD puts on clean pjs every night. If I don't keep on them, they leave the towels on the floor, which means a new towel every day for each of them. I probably average 6-9 full loads of wash every week for 3 people! And probably only one load is for my stuff!
And showers? My DS is the king of the Hollywood shower. He can spend at least 30 minutes in there! And he usually takes one in the morning and one at night.
Last summer, the kids were with their grandma or at camp for 3 weeks out of the month. I was out of town one of those weeks. That water bill? $20!!! So I'm thinking that my bill under normal usage would be around $40-50 a month.
I hear you about the towel thing. I finally bought everyone their own color towel set, they get fresh towels 1x week--one bath towel, one hand towel, one wash cloth. If they throw it on the floor, that's where they find it when they need to dry off. That's it! I keep the supply of fresh towels locked up! Its amazing how quickly they learned to hang up their towel when all they had to dry off with was a damp one from the floor. I flet yucky the first time dd complained that she only had a damp towel to dry off with, but stuck to it, she quickly learned the towel she tosses on the floor is hers. This only works with seperate colors for each family member! It reduces by about 80% the amount of towel washing I was doing--about a load a day! I've learned NOT to keep a stocked linen cabinet, otherwise everyone just grabs another towel whenever. The only towels in the house are those on the towel racks, or on the floor, however the user choses. Has helped with the water bill!

What water bill?
Actually the only plus to having a well is the fact that it's free
it sucks when the power goes out because we also loose water.
