How to Drill a Deep Water Well

Drilling deep water wells has been practiced for hundreds of years.

Ground water is a valuable resource, and even though we might not realize it, it's all around us. Whether you require water for irrigation, home use or a business, wells provide a reliable system to ground water. Not many water wells dry up; however, some do have inconsistent recharge rates. So, it is important to study the area where you want to drill a deep water well. There are three types of well construction: dug, driven and drilled. Drilling is the most efficient way of constructing a deep water well.

Things You'll Need

• Local hydrology information
• Deck engine (low horsepower)
• Truck
• Drilling rig
• Cable tools
• Water
• Bailer
• Welding equipment
• Torches

Instructions

1. Determine the quantity of water you need before drilling a well. Know the recharge rate in the area you want to drill, or flow of water to your well. Know the size of the well you want to construct as well as the static level your well will have once you drill it.

2. Find out if you require a government permit to drill your well. Purchase and utilize a construction hat and boots during the drilling process.

3. Mount the engine on the truck's bed. Attach the drilling rig to the cable, which will cut through the rocks by percussion cutting action.

4. Connect the engine to the drill rig. Combine water to the drilling action to flush out the well system of crushed particles using the bailer.

5. Weld the well for a water-tight seal. Decide on one of two case advancement options for your well: drive cap or drive block. Add the welding in sections of about 10 feet for more efficiency. Weld the casing so it remains firmly on bedrock.

Tips & Warnings

• Cable tool drill rigs are most efficient on soft rock formations. Because of their slow penetration rate, they are most productive on shallow grounds, usually 100 feet or less. Utilize torches if necessary.

• Test your water before consuming it. Maintain a safe distance from septic tanks, livestock yards, petroleum tanks and manure stacks to prevent possible contamination in your water. Even though cable tool drill rigs are reliable, simple to maintain and easy-to-use machines, drilling deep water wells is a fairly complicated and a possibly costly endeavor.
