How long are well drill bits?
This type of tool is alternately referred to as a rock bit, or simply a bit. The hole diameter produced by drill bits is quite small, from about 3.5 inches (8.9 cm) to 30 inches (76 cm), compared to the depth of the hole, which can range from 1,000 feet (300 m) to more than 30,000 feet (9,100 m).
How much does it cost to drill a shallow well?
Cost To Dig A Shallow Well. The average cost to dig a shallow well is between $1,800 and $3,000, or $5 to $10 per cubic yard depending on the depth of the water table. Shallow wells are typically 25′ to 50′ deep, 3 to 10 feet in diameter, and are best in areas without rocks or any bedrock.
How deep should a well be for drinking water?

What’s the difference between a shallow well and a deep well?
Deep wells have higher protections against potential surface contaminants. The equipment involved in these types of wells is less visible than with shallow wells, which require an above-ground well housing to contain the well pump. Their water tends to last longer and require less monitoring for quality.
How deep is too deep for a well?
On average, to be deep enough to reach the bedrock, a water well would need to be anywhere from 100 to 500 feet deep, though there are some places where the well needs to be up to 1000 feet deep.
Are shallow wells better than deep wells?
