What’s the Average Cost of Drilling or Digging a Well?
On average, the cost of drilling or digging a well alone is $6,000, excluding other related expenses.
In the chart below, you can see the typical price range for water well drilling or digging.
The table below also displays the average price of well drilling.
| Cost Category | Cost Description |
| Low-end | $1,500 |
| Average | $6,000 |
| High-end | $9,000 |
As shown in the chart and table, drilling or digging a well is, in most cases, a significant investment.
According to the same sources, the costs of drilling a well can vary widely, and many fees can be controlled or negotiated.
However, the primary cost factor is the well’s depth, which can range from 50 to over 400 feet.
Therefore, the easiest way to calculate a general price is to consider how deep the well will be.
So let’s look at the prices per foot.
Note: Digging and drilling both mean making a hole in the ground, but in specific situations, they represent different techniques, which we’ll explain later in the text. For now, let’s consider them the same thing.
What’s the Well-Drilling Price per Foot?
Well-drilling prices per foot can range from $10 to $70, depending on labor costs and the amount of work required.
You can see the typical price range for a well by calculating the cost per foot shown in the graphic below.
The table below presents the same information.
| Depth (Feet) | Low-end Price ($) | High-End Price ($) |
| 50 | 500 | 3,500 |
| 100 | 1,000 | 7,000 |
| 150 | 1,500 | 10,500 |
| 200 | 2,000 | 14,000 |
| 250 | 2,500 | 17,000 |
| 300 | 3,000 | 21,000 |
| 350 | 3,500 | 24,500 |
| 400 | 4,000 | 28,000 |
The well drilling price per foot increases with the well diameter and can also rise if you live in remote areas or if your soil is low-quality, dry, sloped, or rocky, as these conditions require more labor.
Nonetheless, a useful guideline is $25 to $35 per foot for drilling, with additional costs for the well casing and other factors affecting the overall well drilling cost.
Let’s take a closer look at these additional factors that influence the average cost of drilling a well.
What Factors Affect the Cost of Drilling a Water Well?
Factors affecting the cost of digging or drilling a water well, aside from depth, include both budgetable elements and those beyond your control. These factors are numerous and include:
- Casing
- Distance from house
- Soil type
- Geographic location
- Well-drilling methods
- Well pumps
- Permits
- Electrical components
- Storage tank
- Water purification system
- Maintenance
1. Casing Cost
This structure helps maintain the integrity of the drilled, dug, or driven borehole that reaches the water source. The casing pipe reinforces the well walls and prevents loose soil and rock from entering the system.
Typically, two types of casing pipes are used for wells:
- PVC Pipes: These are the most common and cost-effective option, priced at $7 to $11 per foot, installed. PVC pipes are corrosion-resistant but may not be ideal for deeper wells due to the pressure from surrounding soil and rocks.
- Steel Pipes (stainless steel, galvanized steel, or black steel): Known for their durability and longevity, steel pipes are used in deeper wells and in earthquake-prone areas. However, they come at a higher cost, ranging from $30 to $130 per foot.
Well caps (covers), placed on top of the casing, keep out debris and prevent accidents, while well screens, along with gravel packs (layers of gravel around the screens), located at the bottom of the casing, provide natural filtration by filtering out sediment and contaminants from the water.
Both well caps and screens can slightly influence the overall casing price.
However, the diameter of the casing pipe has the most significant impact on cost—the wider the pipe, the higher the price.
The chart below illustrates the well casing cost per foot.
In the table below, you can also see the cost per foot for well casing with different pipe types.
| Type | Average Cost per Foot |
| PVC | $7- $11 |
| Galvanized Steel Pipe | $32 – $55 |
| Stainless Steel Pipe | $56 – $130 |
In most cases, a pipe diameter of 4 to 6 inches is required, though older wells may need an 8-inch diameter.
The table shows prices for a complete water well system based on pipe diameter and type.
| Depth in Feet | 4’’ Diameter PVC Casing | 6” Diameter Steel Casing | 8’’ Diameter Steel Casing |
| 50 | $1,800 | $3,000 | $4,000 |
| 100 | $3,500 | $6,000 | $8,400 |
| 150 | $5,000 | $9,000 | $12,500 |
| 200 | $7,000 | $12,000 | $16,500 |
| 250 | $9,000 | $15,000 | $21,000 |
| 300 | $10,000 | $18,000 | $25,000 |
| 350 | $12,500 | $21,500 | $29,500 |
| 400 | $14,000 | $25,000 | $33,500 |
The same information is presented in a chart.
2. Distance from House
The closer the well is to the house, the lower the cost, as this reduces the length of the electric and water supply lines, which cost between $50 and $150 per foot.
Distance also affects water pressure, so the farther the well is from the house, the more likely you’ll need a booster pump or storage tank. Therefore, it’s best to put in a well as close to your home as possible.
However, your county’s building department may require minimum distances from the wellhead. Typical requirements include:
- 5-10 feet from your property line
- 50 feet from your septic tank
- 100-200 feet from the septic tank drain field and utility lines
To determine the best location for the well, measure the distance from the proposed well site and consider all important factors using a site plan.
3. Soil Type
Rocky soil, dense bedrock, or any unexpected geological issues will require more time and equipment for contractors to drill a hole compared to softer ground, resulting in an increased labor rate.
However, denser soil offers stability that supports the well casing and prevents collapse, potentially reducing the need for extra materials initially and lowering maintenance expenses throughout the well’s life.
Soil type analysis is one of the eleven key factors to consider before starting any project on your property, not just well installation. To understand its importance and the other nine factors, visit our Site Planning page.
Below is a table showing cost differences in percentages depending on soil type.
| Condition | Cost Differences |
| Easy | -34% |
| Moderate | -16% |
| Partial Rock | +92% |
| Dense Rock | +155% |
4. Geographic Location
Geographic locations vary in geological conditions, such as soil types and groundwater levels, which affect well depth and the overall cost of drilling a well.
For instance, climate conditions differ between California and Arizona, influencing the groundwater levels (well depth), which is the main water well cost factor.
Depth can vary not only by state but also within different areas of the same state, making precise aquifer location estimates challenging.
To address this, drilling companies often charge a fixed price for the first few hundred feet and an additional per-foot rate beyond that depth.
Also, you may try to foresee the average depth for your place at the map-based well research on Maine’s government site [1].
Additionally, location affects labor rates, permit fees, and inspection requirements, impacting the overall well drilling cost.
The table below offers estimated costs for complete well water systems in various states.
| State | Price Range per Foot |
| Arizona | $26-$58 |
| California | $29-$66 |
| Colorado | $28-$63 |
| Florida | $25-$58 |
| Massachusetts | $30-$70 |
| Nevada | $28-$63 |
| New York | $30-$66 |
| Texas | $29-$63 |
| Washington | $29-$60 |
5. Cost of Well-Drilling Method
The choice of drilling method depends on local conditions and the contractor’s expertise or preference.
Although “digging” and “drilling” might seem similar, they are distinct methods for creating a well, with a third option being the driven method.
- Drilling Method: This method is used to reach deeper water sources (which can even be more than 1,000 feet deep) and requires more sophisticated equipment, such as rotary-drilling machines. Consequently, drilling a well costs more than $5,500.
- Driven Method: This method is suitable for reaching depths of up to 50 feet and is ideal for sandy soil. The drilling process resembles pushing a straw into the ground, with a driver inserting a long steel pipe until it reaches the groundwater. Driven wells are easier to install, with an average cost of up to $4,000.
- Dug Wells: These wells are ideal for accessing shallow groundwater. This is the simplest type, going less than 30 feet into the ground and requiring only backhoes, shovels, and lining materials such as stones or bricks. The cost to dig a well starts at around $2,500.
6. Well Pump Price
A well pump is crucial for bringing groundwater to the surface.
There are two main types to choose from: jet pumps (which are above ground) and submersible pumps.
The cost of well pumps ranges from $300 to $2,500, with submersible and larger pumps generally being more expensive.
Additional costs beyond the pump installation price may arise depending on the pump’s location, the distance to the storage tank, and any special inclines.
7. Permits for Installing a Well
In most cases, you will need a permit to dig or drill in your yard, including for the installation of a water well.
Depending on local regulations, you might need approval from a Homeowners Association (HOA) as well as a zoning permit for putting in a well, in addition to the standard drilling or digging permit.
Consequently, you can expect to pay between $200 and $500 for these permits.
Since obtaining these permits can be daunting and time-consuming, it is advisable to check for an option to get a site plan for permits online within 24 hours.
You can then provide this plan to your contractor, who can handle the rest of the application process on your behalf.
8. Storage Tank Cost
A storage tank, also known as a pressure tank, stores water from a well system and maintains consistent water pressure.
You can expect to pay anywhere from $100 for smaller tanks (2 gallons) to $1,100 for larger tanks (44 gallons).
9. Electrical Components
The electrical components required for the water well system to function are:
- Water pump: Draws water from the well to the surface
- Pressure switch: Activates and deactivates the well pump based on the water pressure in the storage tank
- Control box: Manages the operation of a submersible well pump
- Electrical connections (wiring): Links all components to the home’s electrical system
The cost to acquire and install these electrical components ranges from $50 to $150 for materials and $150 to $550 for labor.
10. Price of Water Purification Systems
To make a water well safe for consumption, you must install a water purification system.
You can choose between:
- UV purification
- Reverse osmosis systems
- Activated carbon filters
Depending on the type of purification system (your capacity needs and water usage), the cost can vary from $800 to $15,000. Additionally, you should expect to pay an extra $200 to $400 for installation.
Besides the abovementioned aspects, ongoing costs associated with the water well should be factored in before determining the total cost of drilling a well.
11. Water Well Maintenance Cost
Water well maintenance is typically required on an annual basis, so it’s important to budget for these ongoing costs.
Maintenance tasks include:
- Conducting a flow test to ensure the pump is operating correctly
- Verifying the water level
- Assessing the pump motor’s performance
- Inspecting the pressure tank and switch
- Performing a general check of the water system
- Testing the water quality
- Examining the well equipment
On average, annual maintenance costs range from $200 to $350. However, if repairs are needed, costs can rise up to $900.
Furthermore, you should account for the electricity costs to power the well pump, which can range from $100 to $400 annually.
All of these factors can be adjusted based on the type of well you choose to install.
Cost to Drill Water Well for Different Types
Except for the standard residential well (which we have used as a reference so far), you may have in mind building a different well type.
Your choice depends on the intent of your water usage and the desired water creation method.
Nevertheless, the most common types of wells are:
- Residential well
- Irrigation well
- Shallow well
- Geothermal well
- Artesian Well
The table below shows the average cost to drill a different type of water well per foot.
| Type of Well | Cost per Foot |
| Residential Well | $25-$65 |
| Irrigation Well | $85-$105 |
| Geothermal Well | $20-$40 (labor excluded) |
| Artesian Well | $35-$80 |
| Shallow Well | $5-$15 |
Let’s see each of them in more detail.
Residential Well Cost
A standard residential well is typically drilled to a depth of 100 to 200 feet, costing between $25 and $65 per foot on average for a complete system and installation.
This cost is influenced by soil type and the water table, but it still remains one of the most affordable options.
Here’s a table showing the average prices of factors important for drilling residential wells.
| Item | Average Cost per Foot |
| Drilling Only | $15-$25 |
| Well Pump | $300-$2,000 |
| Well Casing Pipe | $6-$130 |
| Electrical Wiring and Control Box | $200-$700 |
| Pressure Storage Tank and Switch | $300-$2,500 |
| Water Treatment and Purification | $500-$3000 |
| Water Quality Testing | $60-$700 |
| Permit | $200-$500 |
Irrigation Well Cost
Irrigation wells cost from $85-$105 for a complete installation, not including the cost of the sprinkler system if it has not yet been installed.
You can see the average cost of the most important factors for irrigation wells in the table below.
| Item | Average Cost |
| Residential Drill + Pump | $9,000-$15,000 |
| Electrical Wiring | $25-$50 LF |
| Pressure Storage Tank | $300-$2,500 |
| Permit | $450-$500 |
Geothermal Well Cost
Geothermal wells are part of an expensive project for heating and cooling your home.
These wells must be drilled with a specialized rig that creates 3 to 5 boreholes, each 4 to 8 inches wide and 100 to 500 feet deep, spaced 10 to 20 feet apart.
The well drilling price per foot with these special requirements ranges from $20 to $40.
Artesian (Deepwater) Well Cost
Artesian wells have access to high-quality groundwater sources with little chance of contamination and therefore usually have to be drilled deep (150’ to 450’) in specific locations.
Although the cost of water well drilling per foot ranges from $35 to $85 (including installation), artesian wells do not require an electric pump, resulting in lower ongoing expenses and minimal maintenance.
Shallow Well Cost
Shallow well, as its name suggests, is usually 25’ to 50’ deep, and therefore, with a little help, it may be a DIY project.
Consequently, it is one of the most affordable options – the cost of drilling a water well of this kind ranges from $5 to $15 per foot.
Compared to deep wells, it’s easy to maintain and produces less yield but it’s more susceptible to contamination.
How to Save Money on Installing Drilled Water Wells?
To save money on installing drilled water wells, you can apply some smart steps that will not compromise the quality of the project yet make it more affordable.
The best money-saving actions include:
- Get Multiple Estimates: Before hiring a professional, obtain quotes from several drilling companies. Ask for referrals and read online reviews to find reputable services. Compare quotes from your top three choices to find the best value. To further reduce drilling costs, consider hiring contractors during the off-season to avoid seasonal pricing.
- Consider Location: Choose the best well location with a professional to optimize drilling depth and costs. Also, aim to build a well closer to the house to reduce supply line expenses.
- Choose Quality Materials and an Efficient Pump: Investing in high-quality materials ensures your well lasts longer. Also, select an energy-efficient pump that fits your needs without overspending.
- Maintain the Well: Regularly inspect and maintain your well to prevent costly repairs.
Next, let’s explore whether doing it yourself is a viable option for saving money or if you should hire professionals.
Should You Install a Well Yourself or Hire Professionals?
You can put in a well yourself and save a lot of money on labor if you have the right equipment and enough time, but this is feasible only for shallow wells.
If you choose the DIY route, expect to spend at least $3,500 on:
- Well drilling rig kit and site preparation tools ($700-$36,000)
- Well pump ($300-$900)
- Water pressure tank ($100-$300)
- PVC pipe ($400-$600)
- Well drilling kit rental ($800-$1,000 daily)
For deeper wells or those intended for drinking water, it’s best to leave the job to professionals for safety reasons.
Additionally, in some areas, digging a well yourself is illegal, which can lead to various consequences and fines.
For all these reasons, regardless of their labor costs ranging from $1,500 to over $12,000, a professional drilling crew may be a better option, as they have the tools, experience, and expertise to ensure your project meets all quality standards.
So, to reduce the cost of digging a well, consider alternative savings methods, as a DIY approach is unlikely to be cost-effective.
