Water Independence Day!
For us, anyway. We are officially off the county water system today, and using from our cistern. I replaced the electric pump yesterday, and finished the plumbing today. Recently had 5" of rain, which put nearly 3 feet of water in the cistern, topping it off at a bit over 6,000 gallons. We will leave the county water hooked up, and use a little of it, just to keep the account current, but try to limit our use of it to what we get for the minimum charge.
This project has taken several months to complete, and cost us close to $2K for rehabbing the concrete block cistern, lining it with trowelled on Quikwall (fiberglass mortar product), and replacing all the plumbing. We also have a gravity flow outlet in the basement, for draining the cistern, or for simple non-electric use, and a hand pump on the back porch = top of the cistern. Only half of the house roof is used for collecting now, but I have piping to hook up half of the front side of the house also. Our last month's water bill said we used about 3,000 gallons from the county supply, so the cistern has 2 months worth of storage, not being particularly frugal with it.
Wife loves the soft rainwater for washing her hair, and after a particulate.charcoal filter, it tastes just fine. We're lovin' it!

Next is to finish building the woodstove. Have the room ready for it now.
