When you turn on the taps in your home water flows. Likewise, when you turn on the washing machine or the dishwasher, water flows.
Most folks in this country -- well over 99 percent -- are connected to some kind of a collective water system. In general, these systems take water from ground wells or reservoirs, pump it into storage tanks, and then allow gravity to supply the force that makes the water flow into your home. Civilized humans have been using such water supply systems for more than 2,500 years.
Out in the country, however, things are usually a bit different. Well, they're different in the "out in the country" that I'm familiar with anyway.
|Before 'lectricity came in there was a windmill here at the home place.|
Our ranch is miles and miles from the closest municipal water system, and even farther away from any water reservoir. Regardless, we do have running water.
Water for the house and buildings comes from a well about 300 yards from the house. This well also supplies stock water for the roughly 800 acres of the home place.
|There's a well under that cover. The T-handle is a valve in the line leading to stock tanks.|
The well is about 150 feet deep and is equipped with an electric submersible pump. The system has a demand switch which instantly starts the pump when a pressure drop is detected. So turn on a tap in the house and water flows. Or when the water level drops in a stock tank and the float valve opens, water flows into the stock tank.
|Inside the "well house"|
As you might imagine, the stock tanks are supplied from the well via underground pipes. As is the house. That single home place well supplies the house and barn, a dozen outdoor hydrants, and up to a dozen stock tanks.
I don't recall off the top of my head the gallons per minute rating of the well and pump, but I do know that when stock tanks are filling the water flow is reduced at the house. If I'm watering my garden, for instance, and the cows go to water, the spray at the garden sprinkler goes from a 40-foot pattern to a five-foot pattern.
As I noted earlier, the submersible pump is powered by electricity, so when (not if!) the power goes off the water flow stops, at least until I get the generator lit off and switches thrown.
These limitations are sometimes inconveniences, but we've learned to live with them. As have most country folks. In return we get some of the tastiest and best water available in the world.
There's a similar setup down on the south unit where a single electrically pumped well serves eight stock tanks.

There's also a single windmill-pumped well on the south unit which supplies three stock tanks.
Windmills are interesting.
Wind turns the blades, which are connected to a gear box which changes rotational motion into reciprocal motion, from round-and-round to up-and-down. This moves a shaft up and down in the well bore. At the end of the shaft is a clever bore pump equipped with check valves which forces water up the pipe so long as the shaft continues to go up and down.
We've got a half-dozen windmills on the north unit, serving about 15 stock tanks.
The windmills run on "free" energy, so there's no electric bill to pay, but there's also no water flow when the air is calm. Windmills need periodic maintenance, too, and the bore pumps wear out every 5-10 years or so. No such thing as a free lunch. Or drink. I have a place in town, too, and when I carefully crunch all the numbers it looks like I pay about the same for water, gallon for gallon, in town and on the ranch.
Regardless of the system, we need the water. Cows drink 15 or more gallons per day, and the people use a lot of water too.
