At this very moment it is raining in Sparks, Nevada. If I needed water to drink, bathe or for the garden, I would certainly have an irrigation system connected to my roof rain gutter system because of its efficiency. I could have filled a small lake and a few swimming pools in the past hour, with just a little forethought.
My wife and I just completed a 12,000 mile tour of the U.S. When in Texas I got a chart showing the average monthly rainfall in Kerrville, I think it was. Every month had about two inches of rain and there was four inches in May and four inches in October.
Unfortunately, where I am, just north of San Francisco, we have a wet season and a dry season. Other than the usual day of showers around July, it can regularly go months with very little measurable rain.
I did check some of the web sites suggested by others and find that a manual pump for my well is not out of the question. Our present submersible pump is at 180 feet. I don't know what the static water level is. A couple thousand dollars might do the job.
The force needed on the pump handle might be around 13 pounds and it can be plumbed to pressurize the existing tank. I don't recall how many strokes per gallon.
My daughter and her husband live on adjacent acreage. They are planning to build soon and I will have to encourage them to install an oversize propane tank and buy a propane powered generator for their well.
