Quick Answer
A new well installation can cost anywhere from $15,000 to $30,000 or more, depending on the depth and geology of the site, while well rehabilitation, which involves restoring an existing well, can cost between $3,000 and $15,000 or more, depending on the complexity of the repair and the equipment needed.
Factors Affecting New Well Installation Cost
The cost of new well installation varies widely due to various factors, including well depth, geology, and equipment requirements. In general, wells drilled to depths of 100 feet or less can cost around $10,000 to $20,000, while deeper wells, typically exceeding 200 feet, can cost $25,000 to $50,000 or more. For example, a 150-foot well drilled in a sandstone formation might cost around $18,000, while a 300-foot well drilled in a hard rock formation might cost $45,000.
Rehabilitation Costs
The cost of well rehabilitation depends on the specific issues with the well, such as collapsed casings, scaling, or bacterial contamination. Typically, minor repairs, like replacing a casing or seal, can cost $3,000 to $5,000, while more extensive repairs, like installing a new pump or rehabilitating the entire well screen, can cost $10,000 to $20,000 or more. Some wells may also require additional work, such as water treatment systems or corrosion protection coatings, which can add to the overall cost.
Equipment and Labor Costs
Labor costs for new well installation and rehabilitation can vary depending on the location, geology, and local labor rates. In general, labor costs can account for up to 50% of the total cost of a well installation, while equipment costs, such as drill pipes, casing, and pumps, can account for the remaining 50%. In contrast, rehabilitation costs tend to be lower, with labor costs typically accounting for around 30% to 40% of the total cost.
