Well Drilling

The actual well size in Middle Tennessee is usually 6 inches in diameter. The most common method of drilling equipment used is air rotary drilling machines. They are large tandem trucks with weight of around 50,000 pounds. This method uses compressed air to power the drill that works in a rotary motion that chips or grinds the formation along with water that is mixed with the cuttings and is discharged to the surface. Drill rigs are expensive ( up to $500,000.00 ) and the use of the equipment requires considerable skill. Due to the size and the weight of this equipment it is good to have one of our representatives come to the proposed site and make sure that the equipment can get to the chosen well location. All wells must be cased into bedrock, at least 5 feet but no less that 19 feet can be used according to the Tennessee rules and regulations. This is to protect the well from caving in and to prevent contaminants from entering the well. Casing will not be needed for the full well depth, only to solid rock. We use only galvanized casing with a wall thickness of .0188. The use of galvanized casing has been proven not to rust and cause iron scale that might enter your water source and stand up to the test of time for endurance. Your well casing will be properly sealed and grouted with an approved NSF grout. This will form a protective barrier against contaminated water entering your well from the surface or from undesirable aquifers. After the completion of the drilling and the development of the well, we will sanitize your well to insure that bacteria was not induced in the drilling process, and place a sanitary cap on the well. All measures are taken for the protection of the ground water and to provide you with a superior water well.
