Basic Formula for Calculating Well-Drilling Costs
To estimate the cost of drilling or digging a well, you'll need to consider several primary factors:
- Cost of digging or drilling per foot (C): This is the base cost for the drilling process per foot, and it varies based on location, the company hired, and the complexity of the terrain.
- Depth of the well (D): This is how deep (in feet) the well needs to reach the water source.
- Pump and installation costs (P): The costs can vary significantly based on the pump's type and the intricacy of the installation.
- Water treatment system costs (T): If the water from the well requires treatment, there will be additional costs for the necessary systems.
- Miscellaneous costs (M): These are additional costs, such as permits, additional labor for unexpected issues, well housing construction, and other expenses not included in the drilling, pump, or water treatment costs.
- Contingency allowance (CA): This is an additional amount (usually a percentage of the total estimated cost) set aside to cover unexpected expenses or overruns. A common approach is to put this at 10-20% of the total estimated costs.
Given these factors, the basic formula for estimating the total cost of the well would be:
Total Estimated Cost = (C * D) + P + T + M + CA
Breaking this down:
- Drilling costs: This calculation helps estimate the cost associated with the drilling process, depending on how deep the well needs to be.
Drilling costs = C * D - Adding the other costs: After calculating the drilling costs, add the costs associated with the pump, water treatment, and any miscellaneous expenses.
- Adding the contingency allowance: This step is essential to ensure the budget includes an allowance for unforeseen expenses.
Contingency Allowance = (C * D + P + T + M) * (1 + (CA/100))
if CA is a percentage.
Therefore, the complete formula, assuming CA is considered a percentage, would be:
Total Estimated Cost = (C * D + P + T + M) * (1 + (CA/100))
Example Calculation
Let's assume the following for a project:
- Cost per foot (C) = $50
- Depth of well (D) = 100 feet
- Pump and installation (P) = $1,500
- Water treatment system (T) = $1,000
- Miscellaneous (M) = $500
- Contingency allowance (CA) = 15%
Plugging these numbers into our formula would be:
Total Estimated Cost = (50 * 100 + 1,500 + 1,000 + 500) * (1 + (15/100)) = (5,000 + 1,500 + 1,000 + 500) * 1.15 = 8,000 * 1.15 = $9,200
The total estimated cost for this project, including a contingency allowance, would be $9,200.
This formula provides a basic framework for the calculations. However, it's essential to consult with professionals who can assess the specifics of your project and provide a detailed quote, as real-world scenarios can introduce variables that this simplified formula doesn't account for.
