What does well drilling cost?
A new residential water well typically runs $5,500 to $35,000 depending on depth, geology, and pump system; the national average is around $9,000 to $16,000 for a complete system. Depth assumptions drive most of the price difference, so get multiple quotes and ask each driller what depth they are pricing.
How deep will my well need to be?
Most residential wells land between 100 and 500 feet, but it is entirely local; the water table and geology on your road decide it. Drillers who work your area know the nearby well logs; ask what depths they have hit on neighboring properties.
