Getting a well on a small farm property or a backyard garden can be difficult, especially if you're not sure about getting the water well drilling equipment onto your property. You may not even know how much water is needed or how deep your well should be. To test the water potential of your property and to cut down costs, a wash-out well drilling technique can be used to give you a more limited well for personal use. Take a look at a few traits of the wash-out system and how it's made.
Building The Wash-Out Well Drill
The well's drill and water pipe are one in the same. It may look simple at first glance, but there's quite a bit of clever thinking that goes into making the drill.
Your well pipe is either one or multiple connected pieces of pipe that must be put into the ground. Pipe material ranges from polyvinyl chloride (PVC) to copper, galvanized aluminum or even brass.
There is not a separate drill, because the pipe itself is the drill. Some people attach a metal pipe with notches or teeth cut into the end, while others cut notches into the pipe material itself. The teeth are later used to dig and scratch away at the earth below. No part of the pipe drill needs to be removed unless you want a different pipe material.
The length of the pipe depends on how deep your ground water is. You'll need to contact your local agricultural extension if you don't know where the water is located on your property, although some general information can be found at the US Geological Survey (USGS) department. In addition to having enough pipe to reach into the ground, you'll need five or six feet of pipe above ground--enough pipe to mount a hand pump or motorized pump
You'll need to create a way to turn the pipe left and right in order to use the teeth. This can be done by either creating handles out of wood that can be tightened onto the pipe or by bolting a handle around the pipe. Such handles can be found at hardware stores or can made modified from a pipe clamp.
The Wash-Out Process
With the pipe, you can dig and loosen up the ground with water. First, use a shovel to dig around the desired pipe area. An area maybe four or five times the size of the pipe should work well, since it will allow ground water to seep into the deeper hole to help with moisture.
Consider using a post hole digger to dig as deep as you can manually. Post hole diggers can get the job done faster than the wash-out well pipe and can allow you to get a better grip on the pipe. A water well drilling service may carry manual or automated diggers that can get deep enough for you to work with the pipe easier without investing in a deeper well drilling device.
Once you have a starter hole, push a garden hose through the pipe and connect the hose to a water supply. You can use an oil drum or similarly-sized water container, but you may need a second container depending on the ground resistance.
Put the pipe in the hole and start grinding the teeth into the ground. Once you notice the pipe starting to grab some dirt, turn on the water and continue turning. For more information, contact Hudson Valley Drilling or a similar company.
