How to Drive or Drill Your Own Well

One of the hurdles to living off the grid is having a clean water supply. One of the very best ways to address that issue is with your own well.


When deciding on a location for your off-grid homestead, check with your local geological survey office to find out if the soil conditions there will allow you to install a well. Once you know you can dig a well on your land, here are some tips for actually driving or drilling your well.


Selecting a Good Location

Your well needs to be in a place with a higher elevation than any sewer lines, cisterns, or septic systems. Also, check for soil quality. Never build a well in a marshy, wet area. Water is found in sandy layers trapped between layers of coal. You will have to go deep enough (usually at least 30 feet but better water is usually deeper) in order to find water.


Driving a Well

The less expensive, but more physically demanding, way to dig your well is to drive it. However, if the soil in your area is high in clay content, you may find it difficult to impossible to drive your own well and you will have to drill.


Once you have determined that all systems are a go for driving your well, this is what you will need:


A post hole digger to dig a 2-foot deep pilot hole for your well

A well point – a system of galvanized pipe, threaded together, with a well screen and hardened point on the end

A post driver – the same type used to install metal fence posts

Galvanized steel riser pipe in 5-foot sections

A pump


A drive cap

Pipe thread compound

Pipe wrenches

At least 30 feet of string with a weight attached to the end

Once you have gathered your materials, you can begin:


Dig a 2-foot pilot hole with your post hole digger.

With the post driver, drive the first section of the well point into the hole until about 10 inches remains above ground.

Add another section of pipe by removing the cap and installing an internally threaded coupling. Replace the cap to protect the threads and continue driving, adding pipe sections as each section has about 10 inches showing above ground.

You will know you have reached water when you hear a hollow sound when you strike the pipe.

To determine how deep you are into the water table, remove the cap on the pipe and drop the weighted string down the pipe. When it hits the bottom, pull it back up to see how much of the string is wet. Continue driving the well point until you are sure the entire screen is under water.

Connect your pump to your well to see how fast it pumps water. Driven wells do not produce as much water as drilled wells but you should get at least five gallons of water per minute from your driven well. If not, removed the pump, reattach the cap on the end of the pipe, and continue driving the pipe.

Continue to reattach the pump and test the flow as you drive your well in 5-foot increments. Once you have reached a flow rate of at least five gallons of water per minute, you are ready to leave your pump attached and start collecting water.

Drilling a Well

If soil conditions in your area (or physical strength limitations) prohibit you from driving a well on your own, you can either pay a professional to drill the well (very expensive) or you can purchase a kit and drill it yourself.


And if u wants to get the high accuracy.U can consider to purchase PQWT water detector to help you analyse and directly show the point to drill.

Once u bought the PQWT water detector. We will provide the free after sales service and 2 years warranty. It will save your money and time.
