Rural Water Systems – Wells

You probably have water under your property.  Technologies are available to help you find it but you might pay over $10,000 for the work.  Old-timers in the area may know where to drill based on their experience.

Another idea is to look at public records (driller’s reports) for nearby parcels.

Keep in mind that if you drill at the low spot on your property you will be pushing water uphill which means lower pressure the higher you go.  Not really an issue on ground that’s fairly level but if you live among rolling hills, where your corral and arena are 80 feet above the wellhead, you’ll lose about 35 psi by the time water gets to your horses.

No wonder it takes 10 minutes or more to fill a water bucket!

Conversely, if your wash rack is 80 feet lower than the wellhead, water may come out of the sprayer with so much force that it’s dangerous to your horse.

Water pressure typically ranges from 40 to 60 psi at the wellhead.  More about that in the next post.

Your driller will recommend an appropriate  casing.   Sometimes it’s PVC, as shown in the Intro.  The casing below is steel.

Your driller will also decide how far to go.  Usually 50 feet or more beyond the point where water is found.

He will install solid or perforated casing as needed, backfill the space around the casing with sand or gravel, and seal the uppermost portion of the bore with cement.

The bottom of the casing is usually left open, in case the well goes dry and you have to dig deeper.

Subsurface pressure may push water up the casing.  Suppose you hit ‘pay dirt’ at 400 feet but water inside the well is at 340 feet.  This is known as the static water level.

Cost to drill depends on several factors but you can start with $40 to $45 per foot.  If your well is 500 feet deep, you will pay at least $20,000.  This does not include the pump, controls, or anything else.
