OK, you got me curious.
My last bill was for 11CCF for 62 days. If I did the conversions right that works to about 133 gallons per day, and there are three of us here (plus two other people who pass through from time to time), so about 44 gallons per person per day.
Our potable water rate is $1.4674 per CCF, so basically free. My "customer charge" and some random fee total $21.61 but the water itself was only $16.14.
Lot size is standard - 0.138 acres or 6,011 square feet total, of which half is probably consumed by the house and driveway. But, as is quite common around here, we have pressurized irrigation for the yard, so that usage is excluded from both the general house usage above and consequently not reflected in the sewer bill either.
Pressurized irrigation is even cheaper - it was $47.07 for the entire year this year, and I watered my lawn three times a day for about six months. I don't think we really have pumping charges as it is all gravity fed from the mountains and a local reservoir through irrigation canals and then laterals. We do have a pump house for our subdivision of maybe 80 houses that uses electricity, but that is owned and maintained by the HOA and paid for collectively by the residents somehow I'm sure. The water is also completely untreated as far a I know.
@MilesTeg, it works exactly opposite around here. Irrigation water rights started out connected with the land - you got so much per acre per year. The can be separated from the land and sold off, but that is rarely done as they are quite useful to have and helps the land retain its value. But it's seniority based: in years when we have low water, the senior right holders get theirs and the junior right holders have to get by without. The ditch riders know the water rights order and they shift the water in the irrigation canals and laterals as needed. The diverters and such are under lock and key, and there are severe penalties for messing with the irrigation water. This makes sense to me because there is still a lot of farmland and ranch land around here, and the farmers and ranchers rely on their water in order to grow their crops and provide for their livestock.
