I have been enjoying
Eaton County's GIS maps. I found the elevation maps to be most useful.

Shallow well pumps can only "pull" 20' of head. The lowest elevation on my property is only 10' above the water table. The problem is that it is about 1200 feet from my orchard and garden.
If the water table is that high, and can be depended upon, then maybe you should think about an elevated tank and an Aeromotor windmill. They can easily pull from 400 ft or so and the tank elevation will easily feed a drip system even if it is a way's away - assuming you have a way to lay the line. You can usually pick these up used, pretty cheap.
ReplyDeleteMost ranches in Texas now use small self-contained solar-driven water pumps. The third-world UN/World Bank funded antipoverty programs do the same.

ReplyDeleteThis guy and a few others out there. A better way is to use compressed air together with the water, because this helps to jet the cuttings up as you go -- -the air expands as it comes back to surface and this expanding bubble pushes the water and cuttings out ahead of it in a better way. This really works best if you don't have a problem with rocks in your area - e.g. in an area of glacial tills or moraines - if you just have sediments, then you should be able to drill a water well down to 30 ft without too much trouble, and thus be sited closer to where your demand is. There is more information out there on gravel packing your well with sand to give it a longer / better productive life.
Thanks for the heads-up.
