Septic Drain Field Cost

Installing a drain field, also known as a leach field, costs $3,500 to $11,000. The drain field is an important part of the system that carries the wastewater back into the soil after it filters through the tank. Drain fields are typically connected to the tank by perforated pipes running 2 to 4 feet underground. These pipes carry the water into the soil, where it drains out beneath the grass. When installing a drain field, a specialist will look out for the surrounding soil environment to ensure the ground can handle the influx of wastewater. Both installers and homeowners must monitor for signs of drain field clogging or flooding. A swampy, soggy area of the yard or a strong sewage odor can indicate issues with a drain field, which could cost $2,000 to $10,000 to remediate.

How Much Does It Cost to Install a Septic Tank?

On average, the cost of installing a new septic tank system is $3,900. The price ranges from $1,500 to $5,000 for a typical 1,250-gallon tank, which is an ideal size for a three- or four-bedroom home.

This cost is inclusive of the tank itself, which costs $600 to $2,100 or more, depending on the type. Labor costs are also included in the installation price, and usually range from $1,500 to $4,000.

How to Prepare for Your Septic Tank Installation

To ensure septic tank installation goes smoothly, here are a few tips to keep in mind.

Receive Multiple Estimates

Before any excavation or signed paperwork, receive estimates from licensed septic tank installers and read reviews about each company using trusted, third-party consumer reviews. Ensure the contractor you select holds the proper insurance and licensing and includes necessary preparations like excavation and drain field testing in their estimate.

Test the Soil and Obtain a Permit

Septic systems rely on permeable soil surrounding the tank to absorb and naturally treat liquid residue so that it doesn’t contaminate runoff water or leak into the water table. This area is known as the drain or leach field.

Before installing a septic tank, you’re legally obligated to obtain a percolation or “perc” test. This test confirms the soil meets requirements set by the city and local health department. Usually, the soil is required to have adequate amounts of permeable contents like sand or gravel. Once the land passes the percolation test, you’ll be able to obtain a permit and start the installation process.

Note: If you want to put a septic tank on a piece of land, it must pass the percolation test. We recommend ordering a test before purchasing the land you want to use for residential purposes.

Plan for Excavation

Heavy equipment is needed to excavate the large amount of land necessary for a septic tank. If you currently reside on the land, make sure to budget landscaping costs to fix any damage incurred during excavation.

If you’re building a new home, schedule the excavation at a time when it’ll have minimal impact on the construction process. Typically, this is before paving the driveways and sidewalks, but after the main frame of the home is built.

What is a Septic System, and How Does it Work?

A septic system is an underground wastewater treatment structure most often used when a municipal sewer system is not available. They are commonly found in rural areas rather than cities.

A typical septic system consists of a septic tank, a distribution box, and a leach field. A leach field is also called a drain field or soil absorption field. A septic tank will help digest organic matter and separates floatable matter such as grease, oils, and solids from the wastewater.

The system discharges the liquid from the septic tanks into perforated pipes buried in a leech field, designed to release the effluent into the soil slowly.

Although the first septic tanks have been in use since the late 1800s, they did not become popular until the 1960s. Up until that time, a cesspool was common in most homes.

Can you dig your own well?

Drilling a well by hand is a lot of work, but it can be done with the right equipment. Whether you’re looking to drill a shallow or deep well, this skill is perfect for those seeking self-reliance. Wells are normally drilled on private land where city or rural water isn’t available.

How long do septic tanks last in Florida?

A septic system can last decades, from 15 years to 20 years for a steel septic tank and up to more than 50 years for a drainfield. Yet, the longevity isn’t guaranteed and there are several things you can do to help your system reach the upper limit of its functional lifespan.

Well System Pricing Breakdown

To know the cost of the well system, you must take into account the different components. However, you should know that the cost of a well varies from place to place.


Wells are as deep as 1,000 feet into the ground, which can take a lot of money to drill. The depth is for the well to be able to reach the water in the ground.

The expenses of a well vary based on how deep it is. Deep wells are more expensive to construct than shallow wells. A domestic water well runs at around $25 to $65 per foot to dig.

Pump Installation

The pump’s specifications change based on the depth of your well. A sturdy pump is ideal for wells deeper than 200 feet. The expense of a shallow water pump is cheaper than that of a deep-water pump.

The cost of installing a well pump ranges from $300 to $2,000, which is based on the pump model.

Well Casing

Well casing is a cylindrical framework used to keep the well open once it has been dug. It keeps the hole from collapsing into the formation wall.

There are three types of well casings: PVC, galvanized steel, and stainless steel. PVC pipes cost between $6 and $10 per foot, while galvanized steel costs between $33 and $54 per foot. Stainless steel pipes are the most expensive, costing somewhere between $57 and $129 per foot.

Water Testing

After you’ve completed the installation of your well, you’ll need to conduct a water test. This test determines whether or not the well water is safe to consume.

You may perform your own water testing by buying a water testing kit. This kit ranges in price from $20 to $150.

However, for more accurate results, you should test the water in a laboratory. This will cost you between $50 and $650.

How many bathrooms can a 1000 gallon septic tank support?

  1. The majority of regulatory guidelines for the least amount of space a septic tank should take up in a property are determined by the total number of bedrooms in the dwelling.
  2. A septic tank with a capacity of one thousand gallons is the minimum size that is suggested for usage in residential settings.
  3. The minimum capacity tank required is one thousand gallons, which *may* be adequate for a home with two or three bedrooms.

How much does it cost to have a well drilled in Michigan?

In the state of Michigan, how much does it cost for a new well? A well can be bored to a depth of 150 feet for an average cost of $5500, or to a depth of only 150 feet for an affordable cost of $4500. Typically, finishing a job will cost anywhere from $1,500 to $12,000. To get a feel for the landscape, you may anticipate spending anything from $15 to $30 per foot.

Additional Factors to Consider

A septic tank can either be installed under or above the ground. Installing a tank underground is costly because of the digging and footing preparation involved.

Underground septic tanks require a drain field that can be fitted with a soakaway. The soakaway makes the tank require less emptying because it allows for some of the wastewater to filter into the ground. This can reduce your spending over time.

Different jurisdictions require different permits. Some require that an inspector visit and approve the site, which could entail a fee. Septic tank permits vary from state to state, but in general, you’ll need to pay renewal fees upon the expiry of your permit.

Well Drilling Cost

Drilling a well costs $5,325 to $9,180 for an average depth of 150 feet. Most homeowners spend $3,750 to $15,300, or $25 to $65 per foot for well installation. Digging a shallow well costs $1,800 and $3,000. Costs depend on the depth drilled, soil conditions, and the well’s diameter.

Septic Tank Cost: DIY vs. Hiring a Professional

Installing a septic tank system is no small task, but when municipal sewer systems are unavailable, it’s a task that’s perhaps unavoidable. While the costs to install a septic tank may seem high or complicated, it’s often a more cost-effective option to install a septic tank than trying to install sewer lines from the city, if that’s even an option.


Many homeowners are interested in doing a DIY septic tank installation to save money. There are a number of tasks that can easily be accomplished by homeowners. Coordinating soil tests and obtaining proper permits are easy tasks. Homeowners can also remove existing landscaping features or dig the holes and trenches for the septic tank. Beyond these steps, it’s best to consider leaving the actual installation to a professional company that is licensed and insured in order to complete the job safely.

The stakes are high when installing a septic tank system since it’s the method of collecting and purifying infectious disease waste like E. coli. Improperly installing a septic tank could result in foul smells, contaminated water sources, and standing water on the property, all of which can put family and neighbors at risk. With qualified professionals doing the heavy lifting, homeowners can enjoy a smooth system that requires little effort to maintain. Once a septic tank company has been selected, homeowners can work with them to identify any tasks that can be done by the homeowner, if desired.

How Septic Tanks May Be Affected by the Pandemic

You may not have realized it, but your septic tank was very likely impacted by the pandemic and may still be impacted. Septic tanks are sized based on projected need. This includes the number of water sources in the home, the number of occupants, and how many hours a day they are home.

When the pandemic was declared in March 2020, most non-essential workers and school children began staying or working from home. This put high stress on septic systems because more people were using the systems for more hours a day than they may have been designed for.

While some people resumed their normal lives and schedules after a short period, an estimated 25% to 30% of the workforce will continue to work from home once the pandemic is over. Many families have also turned to homeschooling to avoid disruptions during this time, meaning many families are spending more hours at home than before the pandemic.

This may mean your septic system is overburdened. It may need to be pumped more frequently than before, need additional service, or be replaced entirely, depending on its age and condition. Families with septic systems should have them inspected and talk with their septic company about addressing their needs.

Additional Costs and Considerations

With the installation of any septic tank system, there are several up-front costs and considerations to take into account. Permits must be obtained, soil must be tested, land needs to be prepared, and more. On occasion, a septic tank may require removal, which would be an additional cost to consider. While these tasks may seem daunting, they are easily completed with the help of qualified professionals.

Landscape Preparation

Once the best location is found, homeowners can clear the landscaping in preparation for the installation themselves or utilize the help of the septic tank installation company. On average, landscape preparation cost can range between $1,200 and $4,500, but this is often built into the cost of installation at a lower rate.

Soil Testing

Homeowners must obtain a percolation test prior to installing a septic tank to make sure that the ground can accommodate the system and meet local health department requirements. Engineers drill a hole to test soil permeability and the layers of sediment. This costs approximately $1,000 to $2,000 to complete.

Permits and Inspections

Local permits can be obtained once the soil has been tested and the appropriate system has been chosen. The cost of permits is set by local city and health departments who check and inspect the soil and designs. For more significant construction, a building permit may be required and can cost between $400 and $2,500. (Some regions may have lower fees for septic tank permits.)


Leach Field

The septic system leach field is a critical element that must be built properly to avoid problems down the road. This often includes laying the pipework from the house as well. The cost of installing the leach field varies due to the size, soil content, and whether a special drainage system will have to be installed. The average cost is $2,000 to $10,000.


On average, the labor costs to use a professional company to install a septic tank system range between $1,500 and $4,000. This includes the labor, materials, and insurance the company carries. An average rate would be $160 per hour.

Septic Tank Removal

In the event that a septic tank needs to be completely removed or replaced, additional time and labor are required to complete the job safely. The tank must be emptied, dug out, removed, and properly and safely disposed of. The average cost to pump out a septic tank is $250 to $600, and the additional cost to remove and dump a septic tank is approximately $5,500.



A new septic tank or septic system, either for new construction or an existing property, will always cost at least a few thousand dollars. The national average cost of professional installation is about $5,828, with a typical range of $3,138 to $8,518

The overall cost of the project depends on the type of septic system you use, the size of your home, and any additional services you may need to complete the installation. Though the typical price range is a good set of guidelines, keep in mind that you could end up paying as little as $1,013 or as much as $18,163

Most importantly: DON’T attempt to install your own septic tank unless you’re a professional plumber or other specialist experienced with septic systems. No matter how handy you are, no matter how much money you think you’ll save, the risk of DIY in this case isn’t worth it.

Septic Tank Repair Cost

Although the average lifespan of a septic tank is about 20 to 30 years, your system will have normal wear and tear of its components over time. Most septic tank systems have parts that are independent of each other, making replacements a simple process.

Below are some common septic tank components that may need to be replaced or repaired over time:

  • Tank pump: Not all systems will require a tank pump. However, if you do need a replacement, you can expect to pay $600 to $1,500.
  • Tank lid: Lids may naturally crack over time with continued use of the tank itself. Although the replacement part cost falls between $50 and $120, using a professional for the installation will increase the total to $100 to $300.
  • Tank risers: These components help the lid rise to the surface on septic tanks that are buried further into the ground. For these replacements, expect to pay about $350 to $800.
  • Tank baffle: The baffle, essential in directing the wastewater through the septic tank for proper removal, can be replaced for $25 to $400.
  • Tank filter: This component, which helps prevent solids from flowing into the leach field, will cost around $250 to $300.
  • Leach field: As one of the most expensive replacements in a septic tank system, homeowners can expect to pay $4,000 to $15,000.

Homeowners should also consider a septic tank warranty to cover their system when it’s time for repairs. Replacement costs for individual components will cost much less than replacing your entire system.

New Water Well Installation Costs

Installing a new well water system ranges from $1,775 to $30,000 or more, depending on the options you choose to power your well pump and the depth and diameter of the well. Drilling is the most expensive part, followed by the cost of the pump.

Water Well Drilling Process

The water well drilling process varies based on the type of well you are drilling and the equipment used.

  1. Once drilling hits the water table, the hole is cased to prevent it from collapsing on itself and hooked to the water lines.
  2. Pumping equipment to get the water out of the ground is installed.
  3. The well is capped to keep it clean and free from pests and contamination.

Well Water Pump

Well pumps cost $300 to $2,000 to install depending if it’s a shallow well pump or a deep well pump, and the degree of incline from the well to the storage tank. Different types of wells require specific pumps; some need to be submersed while others are placed outside the well. If your well is deeper than 150 feet, or if there is an incline, you’ll need a stronger pump.

Well Water Pumps
Type Average Cost Description
Shallow Well Jet Pump $300 – $900 For wells 25’ deep or less. Placed outside the well and covered with housing. A tank or a booster ensures constant water pressure, and has overload protection which prevents motor burnout.
Deep Submersible Well Pump $400 – $2,000 Submersed inside wells 90’ – 300’ deep. Recommended using a 3-wire pump for easier maintenance. Repairing 2-wire pump’s requires raising it to the surface first.
Convertible Jet Well Pump $400 – $1,200 For shallow wells and deep wells up to 90’ deep. Not submersible; placed outside the well and covered with housing. Useful in areas where the water table fluctuates.

Well Casing Cost

Installing or replacing well casing costs $6 per foot for PVC casing to $130 per foot for stainless steel pipe casing. An average well needs 25′ of casing below the surface that costs $250 to $2,500 depending on soil conditions.

There are different types of casing, depending on where you live: steel, stainless steel, PVC, or concrete. Well casing supports the wall of the well and keeps dirt and rocks out of your water. Well casing is not required when drilling through hard rock as it provides its own support.

 Well Casing Cost   Type Average Cost Per Foot

Well Casing Cost
Type Average Cost Per Foot
PVC $6 – $10
Galvanized Steel Pipe $33 – $54
Stainless Steel Pipe $57 – $129

Earthquake-prone areas require steel casing that won’t snap if the earth shifts. Casing should be at least 5 inches nominal inside diameter, and at least 1 inch larger than the outer diameter of pumping equipment installed.

Cost To Put In Well and Septic System

A septic system costs $3,280 to $5,040 to install by itself on average. The cost to put in a well and septic system ranges from $6,000 to $20,000 depending on the type of septic system, type of absorption field, size of the septic tank, and depth of well drilling required.

Most rural or off-grid homes use a well to deliver fresh water and a septic system to dispose of wastewater. Sometimes, homeowners have a choice between digging their own, or hooking into municipal water and sewer systems.

Well Caps and Seals Cost

Sealing or capping a well costs $20 to $40 and are required to keep your well safe from contaminants.

  • For capped wells, the water and power lines are underground. In northern regions where the frost line is 3 – 4 feet deep, there will be a sanitary well cap on the well above ground, and the pump will be suspended on a pitless adapter below the frost line.
  • For sealed wells, the water and power lines pass through a gasket.

Well Water Storage Tank Cost

The cost of well water storage tanks runs from $104 for a 2-gallon tank to $714 for a 44-gallon tank. Water tanks, or pressure tanks, draw water from the well and keep it under pressure, and delivered immediately when someone uses an appliance or a faucet in your home.
