- Dig a trench that’s 4 × 26 × 3 ft (1.22 × 7.92 × 0.91 m). Use either a shovel or an excavator to make a hole in the spot where you want your tank. Keep digging until the hole is 4 feet (1.2 m) wide, 26 feet (7.9 m) long, and 3 feet (0.91 m) deep. You can usually rent excavators for digging from a heavy machinery supply store.
How does a poly septic tank work?
The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.
Can you have a septic tank without a leach field?
The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.
How long do plastic septic tanks last?
A septic tank can last between 20 and 40 years. The lifespan depends on the tank’s material. A steel tank lasts 20 years, while a concrete tank lasts 40 years. Plastic tanks can last as long as 30 years.
What is the smallest septic tank available?
If you’re looking to install a septic system, the smallest tank size you’re likely to find is 750-gallon, which will accommodate one to two bedrooms. You can also opt for a 1,000-gallon system, which will handle two to four bedrooms.
What size septic tank do I need for a tiny house?
Tiny homes typically require a 500 to 1,000-gallon septic tank. Though, it’s not always possible to implement a tank of this size. In some states, for example, the minimum tank size is 1,000 gallons. There may be exceptions to this rule if your home is on wheels.
What to put in septic tank to break down solids?
Yeast helps actively breaks down waste solids when added to your septic system. Flush ½ cup of dry baking yeast down the toilet, the first time. Add ¼ cup of instant yeast every 4 months, after the initial addition.
How do you keep a plastic septic tank from floating?
How can you prevent this from happening?
- Fill the tank with water after it’s pumped to keep weight in the tank and prevent floating.
- Divert rainwater runoff away from your system.
- Avoid pumping the tank during wet seasons if there is a risk that the tank could float.
Can you pump a plastic septic tank?
When is Pumping a Septic Tank Not Recommended If the septic tank is plastic or fiberglass, and if ground water is still high around the septic tank, the tank may actually float up out of the ground, leading to damaged septic piping and more costly repairs.
Can I use a plastic water tank as a septic tank?
Plastic septic tank installation is less complicated and can be stored in a wide variety of places. Septic tanks constructed by polyethylene resins are less susceptible to cracking too. Concrete septic tanks are more expensive, crack easily, and can be challenging to repair.
Are septic tanks plastic or concrete?
Concrete septic tanks are superior to fiberglass or plastic because they are watertight and heavy duty, making it the ideal preferred storage vessel for on-site septic storage and treatment. In the United States, there are 40 million septic systems in service.
Do plastic septic tanks collapse?
Guide to Plastic or Fiberglass Septic Tanks Fiberglass or Plastic Septic Tanks: are very resistant to some of the problems occurring with concrete (cracks) or steel (rust) septic or home made (collapse) septic tanks.
Do you need to pump both sides of a septic tank?
Septic tanks installed after the late 1980s have two compartments, and it is important to pump out both compartments each time. Most homeowners are unaware when their septic tank has two compartments; some companies use that to their advantage, charging to pump both sides of the tank but only actually pumping out one.
How to Construct a Small Septic System
Documentation Download Documentation Download Documentation There are two main sections to most private septic systems: the holding and digesting tanks, and the dispersion field or leach field. As the liquid waste in the first holding tank fills up, it will be transferred to the second holding tank. Once the second tank is completely filled with liquid, the liquid will dissipate into the earth underneath it. The system displayed here is a modest system that is intended for limited use by two persons who do not need to do laundry.
When compared to a conventional house septic system, this system employs two 55 US gallon (210 L) drums, rather than the 1,000–2,000 US gallon (3,800–7,600 L) tanks that are utilized in a standard home septic system.
Property owners considering installing a system similar to this one should be advised that this system would fail inspections by any public health department in the United States, and that the owner may be liable to a fine if the system was discovered in operation by a health official.
Toilets that conserve water nowadays utilize less than two litres of water every flush.
It might be a lifeline for those who live in areas where septic treatment is not available.
Part 1 of 3: Cutting the Tanks
- 1Cut a hole in the center of the top of each drum that is the same size as the outer measurement of the toilet flange. Take the outside diameter of the toilet flange that you’re using and multiply it by two. Place the hole close to the edge of the drum so that you may simply connect them to pipes in the near future. Cut the drums using a saber saw to make them lighter
- 2 Each hole should be capped with a 4 in (10 cm) toilet flange. Push the flanges into the top of each tank until they are flush with the surface. As soon as the flanges are in position, tighten them down so they don’t move or shift once they are in place. Advertisement
- s3 Cut a hole in the first drum that is 4 in (10 cm) in diameter on the opposite side of the drum from the hole in the top. Placing the hole approximately 4–5 inches (10–13 cm) below the top of the drum and ensuring that it lines up with the hole on the top of the tank are the most important steps. 4 Make a hole in the wall with a saber saw or a hole saw. Cut two holes in the side of the drum at 45-degree angles to the center of the hole on the top, one on each side of the drum. The center line is the line that runs through the middle of the hole on the top of the drum. Make 45-degree angles from either side of the centerline, then mark them on the second drum using a permanent marker. Make your holes in the barrel by cutting through the side with a saber or a hole saw and drilling them out. Advertisement
Part 2 of 3: Placing the Tanks Underground
- 1 Dig a trench that is 4 ft 26 ft 3 ft (1.22 m 7.92 m 0.91 m) in length and width. Excavator or shovel are both good options for digging a hole in the ground where you wish to put your tank. Continue excavating until the hole measures 4 feet (1.2 m) in width, 26 feet (7.9 m) in length, and 3 feet (0.91 m) in depth.
- Excavators for excavating are often available for hire from a heavy machinery supply company. Look for equipment rentals on the internet
- The majority of heavy machinery supply stores will lend out excavators for excavating jobs. Make use of the internet to look for equipment rentals.
Part 3 of 3: Connecting the Drain Pipes
- Put a stake into the ground and level it with the bottom of each of the 45-degree bends. 2Put a stake into the ground and level it with the top of the 45-degree bends. It doesn’t matter what sort of stakes you use since they all work. Use a mallet or hammer to pound the stakes into the ground. Attach a one-inch-wide block to the end of a four-foot-long (1.2-meter-long) level using duct tape. This will assist you in ensuring that you create sloped drain pipes so that your tanks can empty
- 3Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
- 4Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
- 5Place another stake approximately 37 8ft (1.2 m) down the trench from the first one. Drive the stake down until it is the same height as the first one using your hammer or mallet
- 4 Place the end of the level without the block on the first stake and the block on the second stake to complete the level without the block. Continue to pound the second stake into the ground until the level is balanced. 1 inch (2.5 cm) lower than the previous post, or 1 inch (0.64 cm) lower per 1 foot (30 cm)
- 5Repeat this method until you have stakes running the whole length of the trench
- Continue to place stakes down the rest of the trench every 37 8feet (1.2 m) from the last one, ensuring that the stakes slope away from the drums
- 6Place gravel in the trench until the top of the gravel is level with the top of the stakes
- 7Place gravel in the trench until the top of the gravel is level with the top of the stakes The gravel will now slope away from the drums at a rate of 1 4 inch (0.64 cm) per 1 foot (30 cm) of horizontal distance
- 7Place 20 ft (6.1 m) of perforated drain pipe into each hole on the second drum
- 8Place 20 ft (6.1 m) of perforated drain pipe into each hole on the third drum
- 9Place 20 ft (6.1 m) of perforated drain pipe into each hole on the fourth drum
- 10P Insert the ends of the drain pipes into the 45-degree bends on the lower drum to complete the installation. 9Make certain that the perforations in the pipes are facing down so that liquids may soak back into the earth
- 8checking the pipes with a level to ensure that the 1 4in (0.64 cm) slope is consistent throughout the length of the pipe. Fill up any gaps in the slope by adding or removing gravel under the pipe. Seal the 45-degree and 90-degree bends that connect the lower and top drums, respectively, with silicone. For the greatest seal possible on your drain pipes, use a two-part epoxy or silicone caulk. For this purpose, consider utilizing flex pipe, which will yield a little bit if the ground changes. Tenth, fill the lower drum halfway with water to keep it from collapsing under the weight of all the gravel. Place the remaining gravel over the trench and into the bottom drum, covering it completely. 11Lay landscape fabric over the top of the gravel. As a result, the dirt will not be able to seep into the gravel and you will be able to keep proper drainage on your tanks
- 12Fill the remaining trench area with soil, compacting it to the original grade. When you have finished filling up the area with your dirt, check to see that the ground is level. 13Fill the upper drum with water, leaving the top pipe from the first tank exposed so that you can readily reach the tanks if you need to drain them later. 14Fill the lower drum with water. Fill the top drum with water and pour it directly down the exposed pipes on the bottom drum. Continue filling the drum until it is completely filled, then secure the top with a cap to keep out the elements. Advertisement
Community Q A
Create a new question
- Question What is considered a low level of use? Low consumption is defined as less than 125 gallons per day. Question Was the ‘y’ elbow on the first tank’s tank for any particular reason? Is it left open or sealed when it has been completed? Isn’t it going to stink if it’s left open? The clean out requires a threaded cap or plug, which is provided. Question What kind of water do you use to fill it? “Fill” is the most important term here. Continue to fill the drum with water until the level does not rise any more
- Question Suppose I neglected to attach a slip coupler to the perforated pipe and only had 10 feet of it. Is it still possible to use this? Yes, however you will need to raise the depth of the field in order to get the same cubic feet of capacity
- Nevertheless Question What is the best way to find out if something is legal in my state? This is a quick and easy approach that is unlikely to be appropriate for long-term usage in the majority of states. It is possible that the property owner and/or the installation will be penalized if this is uncovered. Question Is it possible to utilize two or three 275-gallon water totes instead, or a water tote and barrel combination? It doesn’t matter either direction you go. It’s best to utilize a single tote and a barrel as a digestion tank and a distribution box if you have only one tote. Question What is the purpose of filling the higher barrel with water? You fill the top barrel with water so that when sewage waste is introduced into the barrel, it flows into a sufficient amount of water to initiate the anaerobic digestion process. Question What is the best way to clean up this system? If there is enough bacteria in it, it will clean itself with minimal effort. If it starts to fill up, you may call a septic service to have it emptied
- If it doesn’t, you can do it yourself. Question What is the correct grade slope of the drain field for every ten feet of length of the drain field? It is possible for the field’s bottom to be level. When running away from the drums, the pipe system should be sloped at 2 percent, or 2.5 inches every 10 feet. Question Is it possible for this system to freeze in the winter? And might I use antifreeze in the mix as well? Antifreeze will destroy the beneficial bacteria that are required for the process to function properly. The process is biological, and it will generate some of its own heat as part of the process. It’s always possible to dig a little deeper to gain a little extra insulation above it.

- The horizontal side of the “Y” links to the waste source, and it should be fitted with a connector that is compatible with the source supply line
- Instead of using a 90° elbow, you should join two of them together to produce a U-shaped connection. In this manner, the end that is in the first barrel will be pointed towards the bottom of the tank, rather than the top. This should be reinforced with a short segment of straight pipe that is several inches deeper towards the bottom. Solids either float or sink depending on their density. They don’t seem to congregate in the middle. As a result, only the broken down liquid waste makes it to the second tank, and the solids are never seen again. The same procedure should be followed for each of the drainage pipes that originate from the second barrel. Just to be completely certain that no solids find their way into the global drain field, the waste is dumped into the first tank, with the solids settling to the bottom of the first tank. Whenever the liquid level exceeds the outfall to the second tank, it is drained into the tank below it. If there are any solids present, they will sink to the bottom. Whenever the liquid from the second tank reaches one of the two outfalls, it is transported to the gravel leaching field for dispersion. Over time, the vast majority of the solids will liquefy and disperse. Solids may accumulate at the top of the tank after many years, necessitating the removal of the solids. Thirty percent of the waste is absorbed into the earth, with the remaining seventy percent being dissipated by sunshine. It is important not to compress the soil since this would interfere with the evaporation process
- The vertical side of the “Y” will be used to pump out the tank after it is entirely filled with solids
- The depth of the trench should be proportional to the depth of the waste source line. If the line is deeper or higher than the one depicted, you will need to dig the trench deeper or shallower to suit the new line depth or height. It’s not that difficult to find out. In the event that you have a septic system that is too shallow, it may be more susceptible to damage. After a period, you may discover that the ground has sunk below the trench’s location. Fill it in with extra dirt and compact it
- It is assumed that you are familiar with working with ABS plastic pipe. In addition, you must have the necessary tools to dig the trench (or be ready to put in a lot of effort).

- This is a system with a relatively limited capacity. This is not intended to suit the demands of a big family or group of people. It is intended for use with a modest travel trailer and two individuals. In order to extend the life of this little septic system, it is recommended that you do not place anything else in it but water, trash, and toilet paper. You may have to pump the upper drum once or twice a year if you don’t do so. During the course of five years, the system depicted here will only require pumping twice. Do not drive through the area where the drums are located. When establishing a septic system, make sure to adhere to all applicable municipal regulations. It is against the law to establish a septic system without first obtaining a permission. In the permission, you can find information on the local regulations for installing a septic system. You should avoid situating a septic system too close to trees since tree roots will grow into your lines, block them, and eventually cause damage to your system.

You may install a septic tank system yourself to save money on the costs of hiring a professional septic designer and digger, which can add up quickly.
Even if you design your own DIY septic tank and drainage system from scratch, the cost of installing a new septic system is high. Although it is possible to save money by establishing your own septic tank system, it is not recommended.
Costs of a DIY Septic System
The connection of a waste disposal system to a septic tank is critical for the health and cleanliness of the community. The installation of a septic system will be required if your property is located in an area where there is already no underground sewerage system. The public health fees for permits to construct a septic tank system are determined mostly by the county in which you live, but you will almost certainly be unable to avoid paying the permit charge. In order to establish the retail prices of yourDIY septic system design, which includes the drain field, distribution box, and pipes, you must first determine the price of the building supplies.
When shopping for hardware and home improvement supplies, compare prices amongst different establishments.
On top of that, you’ll have to consider about the excavation as well.
Before You Start Digging
Before you begin the actual building work, it is generally a good idea to do a thorough assessment of the situation. Get yourself a scale map of your home and property before you get your shovel out and start digging about in the dirt. The backyard, below the garage, or any side of the house that is near to a roadway are the greatest places to install a household septic system. The position of the septic system must be determined before any digging can begin. This is a very important phase in the process.
When installing a tank, it is vital that it is done right the first time.
The Site Evaluation
In most jurisdictions, the old perc test has been replaced by a site evaluation as a means of demonstrating to your local health authority the treatment characteristics of your property’s infrastructure.
DIY Perc Testing
In the past, the perc test was performed by simply dumping a pail of water into a tiny hole in the ground and then timed how quickly the water soaked into the soil with a stop-watch. The site inspection is carried out at the bottom of a 6-foot-deep trench. Unlike the perc test, which only measures the absorption speed of a small section of the property, the site evaluation measures the absorption speed of a much larger region over the soil face.
In the past, the perc test was performed by simply dumping a pail of water into a tiny hole in the ground and then timed how quickly the water soaked up into the soil with a stopwatch. In a six-foot-deep pit, the site evaluation is carried out. The site evaluation tests a considerably larger region over the soil face, whereas the perc test only gives you the absorption speed of a tiny portion of the land.
Drainfield Trench Size
This does not affect the size of the drainfield, which is independent of the number of bathrooms or fixtures on the property.
Almost all health departments employ the following methods to determine the flow rate:
- An individual’s residence’s total number of bedrooms The amount of persons that are present in the residence
- Water use on a daily basis
The volume of sewage that must be discharged into the drainfield is determined by the flow rate. Once you have determined the kind of soil under your prospective drainfield, use the table shown here to calculate the drainfield area necessary for your house size, and you will have the drainfield size you require.
Size of The Septic Tank
The size of a septic tank construction is decided by the number of people living in the home or on the land for which it is being built. Consult the metric standards for the area in which the construction is to take place before proceeding. This is the most accurate method of determining the amount of septic tank you should use when constructing your own septic tank system. The size of your DIY septic system will also decide how frequently you will need to have your DIY septic system pumped by a professional septic pumping service, which will be determined by the size of your septic system.
Creating the Drawings
Before we can begin construction on our septic system, we must first develop the necessary designs to fulfill the requirements of your local health authority. Your DIY septic system designs may need to be more detailed than you think they need be, depending on your state’s requirements. All structures, pathways, property borders, retaining walls, and the position of the original test holes, on the other hand, must be clearly depicted.
Your drainfield plan will necessitate the construction of a minimum of two ditches of similar size. The division of the water flow into two, three, or more lines is performed by using a distribution box, also known as a D-box, to split the flow. It is used in the distribution box to distribute water through pipes that include flow control valves in the form of eccentric plugs that distribute the water evenly across several drain lines. The effluent must travel downhill from the tank outlet, past the distribution box, and down the individual trenches before being disposed of.
Apply for a Building Permit
Now that you have the drawing, you should submit your ideas to the local health department’s office for consideration. You will be required to complete an application form as well as pay the applicable permission cost. Following that, you will need to wait for the designs to be examined and authorized by the board of directors before moving on to the final construction phase of the project.
Building a Septic Tank System
To begin the construction process, the first step is to sketch up a rough schematic of the septic system. You’ll utilize this layout to put your construction designs into action on the ground. It is necessary to project the layout and position of all of the different components of the septic design onto the site.
Excavation of the Septic Tank System
When it comes to digging the site in order to prepare for the construction of the septic tank and drain lines, it is important to pay close attention to elevation in order to get the best possible results. The health inspector will need to inspect the job one more time after you have finished all of the excavation before you can begin backfilling.
Once you have finished all of the excavating, you will need to schedule another appointment with him for a final inspection of the job before you can begin backfilling.
Backfilling the Septic Tank System
During the building process, all of the tanks, pipelines, and vaults should be backfilled around the perimeter. Your local authority may mandate that all tanks be subjected to vacuum testing, pressure testing, or water testing. Aside from that, an increasing number of counties are demanding leak testing of the tank these days. Consequently, the final backfilling of the concrete tanks can be delayed until after the final inspection to check for leaks has been completed. The final backfilling should not be completed until after the final health department inspection has been completed.

Permits Before Digging
In order to discover if a home-made septic system is suitable in your location, check with your local health department and county government offices first. If they are, make a note of any regulations and get any licenses that may be required before you begin working. You must adhere to the local septic system standards as closely as possible during the construction process, or you may be forced to dig up your system and start over from the beginning later on.
Early Site Planning
You’ll need to consider these factors when determining the ideal location for your septic tank and drainage system: most counties require soil testing to assess the percolation rate (drainage ability) of the soil as well as the seasonal water tables of the land. The optimal location for the septic system will be tested and approved by the local county planning boards and health agencies. County health agencies and planning boards will also provide you with information on how deep you should install your septic tank and drain field pipes.
Consider 75 gallons of septic tank space per person each day as a rough estimate.
Always err on the side of caution and budget an additional 150 gallons a day to account for visitors and other miscellaneous consumption. Make use of a 1,000-gallon tank if at all feasible so that the sludge does not have to be pumped out as frequently as it would with a smaller tank.
Septic Tank Site Preparation
You may dig the septic tank pit yourself using a backhoe or shovel, or you can hire a digger business to do it for you. Even though digging by hand will take more time, doing so will save a few hundred bucks if this is wanted. You may also save money by preparing the hole so that the tank can be dumped in by the person who is delivering it as soon as it arrives. Prefabricated septic tanks start at $600.00 and rise in price in direct proportion to the amount of space they occupy. Connect the drain pipe that leads to the drain field either before or after the tank has been installed in the ground, depending on your preference.
The drain field, where the material from the tank will finally end up, should be at least 10 feet away from the dwelling as well as any body of water, such as a pond or river, where the material would eventually end up.
Septic systems typically require a total drain area of 100 feet in order to function properly.
It is also necessary for the trench to have a very little downhill slope in order for waste to be able to flow out of the drain pipe.
Connections and Finishing Touches
After preparing the site and installing the septic tank, you will be able to connect the various components of the septic system together. The perforated drain pipe should be connected to the line that comes out of the septic tank. Add extra gravel and a thin layer of filter cloth to the perforated pipe in order to prevent dirt from filtering down to the drainpipe. Finally, fill in the trench with the soil that was previously taken from it by hand.
The Advantages and Disadvantages of a Septic Tank System
When it comes to dealing with waste water in your house, there are two options. One method is through the use of municipal sewage lines, which convey waste water from your property to a treatment plant in the area. A septic tank is the second type of source of sewage. In light of the above, the specialists at Steve Mull Plumbing would like to discuss with all of our valued clients the different pros and disadvantages of a septic tank system, as well as some alternatives. A septic tank is a tank that is built beneath the earth and away from your home.
The water itself is pushed out of the septic tank and into the earth, and the waste is collected separately until it is time for periodic maintenance, at which point it is pumped out once again.
Because a septic tank causes you to concentrate on the quantity of water you are using at any given moment, many individuals find themselves being more efficient because they do not want to overload or overwork their septic system.
The Advantages of a Septic Tank System
Because massive underground sewer lines are extremely expensive to construct, install, and operate, a septic tank is often the most cost-effective option. A septic tank, on the other hand, is far less expensive to build and does not need homeowners to pay monthly maintenance fees. Another advantage of a septic tank is that they are extremely long-lasting and, when properly kept, need very little maintenance. The fact that septic tanks are ecologically friendly is a last advantage of using one.
Furthermore, because all of the recycled water is absorbed by various sorts of plant life in the surrounding area, it is extremely ecologically beneficial.
Disadvantages of a Septic Tank System
It is possible for septic lines to become blocked by a variety of different products that should not be flushed down the toilet or poured down the drain. It is possible to discover a blocked septic tank by the presence of a slow-draining sink or tub, as well as toilets that flush at an equally sluggish rate. If you see any of these indicators, contact a licensed plumber immediately so that they can assess the situation and suggest appropriate remedies. An additional drawback of a septic tank is that it must be pumped every 2-5 years, at a cost to the homeowner ranging between $250 and $450 every pumping.
- When a drainage pipe is broken, whether by tree roots, a digging accident, or even a car or other object interfering with the pipe, you will almost certainly find yourself in the midst of a major problem and a resulting mess.
- This will necessitate the urgent replacement of the damaged drainage pipe, which can be rather expensive.

Learn how much it costs to Install a Septic Tank.
Septic tanks range in price from $3,157 to $10,451, with an average cost of $6,804 per tank. Installation of a conventional 1,000-gallon tank for a three-bedroom home might cost anywhere from $2,100 and $5,000. Materials range in price from $600 to $2,500, without labor. A comprehensive septic system, which includes a leach field (also known as a drain field), tank, and plumbing, can cost between $10,000 and $25,000 to install. A leach field installation might cost anywhere from $5,000 to $20,000, depending on the kind.
In the end, the cost of installing a septic tank is determined by the kind of system, the materials used, and the size of the tank.
The two types of systems covered in this book are aerobic and anaerobic systems. This course will teach you about the several sorts of settings, such as conventional, drip irrigation, mound irrigation, evapotranspiration, recirculating sand, constructed wetland, and chambered irrigation.

New Septic System Cost
Most tanks and systems cost between $2,000 and $10,000 to install a new typical anaerobic septic system. Aerobic systems range in price from $8,000 to $20,000. Depending on the size of your property, the composition of the soil, and the level of the water table, you may even have to pay an extra $10,000 or more for an alternative, specialized drain or leach field. Septic systems are composed of three major components:
- Septic tank: Either anaerobic (requiring no oxygen) or aerobic (requiring oxygen but more complicated but more efficient)
- Water runs to a leach field after it has been cleaned and separated in the septic tank, where it will naturally drain through sand, gravel, and soil in a cleaning process before reaching the water table
- Water table: Plumbing: A drainpipe to the tank, followed by another branching pipe to your field will be required.
Optional components include the following:
- Some types of systems use a dose or pump tank, which pumps wastewater up into mounded or elevated leach fields and recycles the water in some cases. Pump for aeration: If your aquarium is equipped with an aerobic system, you’ll want an aerator to force oxygen into the tank.
Find Local Septic Tank Installers
The installation of a traditional anaerobic system typically costs between $3,000 and $8,000 on average. Anaerobic systems are often less expensive to build than aerobic systems, which are more complicated. However, because they are less effective at cleaning the tank, you will need a bigger leach field to accommodate the increased burden. An anaerobic septic system is a very basic system that consists of a pipe that runs from the home to the tank and a branching pipe that runs from the tank to the drain field, among other components.
Aerobic Septic System Cost
Aerobic systems, which are those that require oxygen to work properly, cost on average between $10,000 and $20,000 per system. If you’re moving from anaerobic to aerobic fermentation, you’ll almost certainly need a second tank, but the conversion will only cost you $5,000 to $10,000. Aerobic systems break down waste more effectively in the tank than anaerobic systems, allowing you to use a smaller drain field in many cases – which is ideal for houses with limited space. An aerobic wastewater system is a wastewater system that depends on aerobic bacteria (bacteria that thrive in the presence of oxygen) to break down trash in the tank.
You’ll need an aerator as well as an electrical circuit that connects to the system to complete the setup.

Leach Field Cost
Installing a leach or drain field, which is a component of your septic system, can cost anywhere from $3,000 to $15,000 in total. The cost of a typical drain field ranges from $2,000 to $10,000. The drain field, also known as the leach field, is the component of the septic system that is responsible for returning wastewater to the soil. Most of the time, a flooded area in the yard or a strong stink of sewage on the property is the first symptom of a problem with the drainfield.
It is possible that you may require further treatment for blocked or flooded fields, which would increase the cost of the drain field repair from $10,000 to $50,000.
Alternative Septic Systems Cost
When you have a tiny property, a high water table, high bedrock, poor soil, or just wish to utilize less space, an alternate septic system is a good choice.
Mound Septic System Cost
Installing a mound septic system can cost between $10,000 and $20,000 dollars. In places with high water tables, thin soil depths, or shallow bedrock, this is the most costly system to build; yet, it is frequently required. In order to create a drain field, it uses a raised mound of sand rather than digging into the soil. Its extra cost is a result of both the additional technology required to pump sewage upward into the mound and the materials and labor required to construct the mound in the first place.
Recirculating Sand Filter Septic System Cost
Sand filter septic systems range in price from $7,500 to $18,500. They can be built above or below ground depending on the situation. In order to disperse the wastewater in the ground, they employ a pump chamber to force the wastewater through a sand filter. The liner of the filter box is normally made of PVC. This is accomplished by pumping the effluent through the sand and returning it to the pump tank, where it is then disseminated throughout the ground.
Drip Septic System Cost
Drip systems range in price from $8,000 to $18,000, depending on the size and complexity. They operate in the same way as previous systems, with the exception that they employ extensive drip tubing and a dosage mechanism. They deliver lower dosages over a shorter period of time, which is particularly effective at shallow soil depths. This method is more expensive than a standard system since it requires a dosage tank, a pump, and electrical power to operate.
Evapotranspiration systems range in price from $10,000 to $15,000 per system. In order to allow the liquid to evaporate from the top of an open-air tank, they employ a novel drain field configuration. They’re only usable in dry, arid areas with little rain or snow, thus they’re not recommended.
Built Wetland System
Built-in wetland systems range in price from $8,000 to $15,000, with the cost increasing if an aerobic tank is included. They are designed to simulate the natural cleaning process observed in wetland ecosystems. After traveling through a wetland tank, where it is treated by microorganisms, plants, and bacteria, it is returned to the soil. The waste also has the effect of assisting the growth of wetland plants and the population of microbes.
Installation of chambered systems ranges from $5,000 to $12,000 dollars. They employ plastic perforated chambers surrounding pipes, which are frequently laid in sand, to keep them cool. Gravel is no longer required as a result of this. They are quick and simple to install, but they are more subject to crushing pressures, such as those caused by automobiles.
Septic Tank Replacement Cost
The cost of replacing a septic tank ranges from $3,000 to $10,000. From 30 to 40 years, you may anticipate your system to serve you well. The system may crack or corrode as a result of the failure and the resulting contamination of groundwater with toxic waste is an issue. When this occurs, the well water may get polluted, the yard may become marshy, and the septic system may become inoperable or fail completely. Here’s a breakdown of the various components of a septic tank, along with an estimate of their usual costs: Replacement of a septic tank pump costs between $800 and $1,400.
Replacement of the filter costs between $230 and $280.
Replacement of a tank lid costs between $30 and $70. Drain Field Replacement Cost: $7,500. When replacing an aerobic system, talk to your service expert about the advantages, disadvantages, and expenses of upgrading to a more efficient aerobic system.
Septic System Maintenance Costs
It is essential that you pump and clean your septic tank at least once a year. In addition, you should get it examined at least once every three years. The proper maintenance of your septic tank will save you money in the long term, and it will also help you avoid potentially hazardous situations. The Environmental Protection Agency (EPA) suggests the following steps to keep your septic system in good working order:
Inspect and Pump Your Septic Frequently
Typically, the cost of septic tank pumping runs from $300 to $550, or around $0.30 per gallon – most septic tanks have capacities between 600 and 2,000 gallons. Every three to five years, you should have your septic tank inspected and pumped by a professional. If you have a bigger home (with more than three bedrooms) and you tend to use a lot of water, you should try to get it pumped at least once every three years. An checkup of a septic system might cost anything from $100 to $900. Your septic inspector will do a visual inspection of the system.
- Initial inspection costs between $250 and $500
- Annual inspection costs between $100 and $150
- And camera inspection costs between $250 and $900.
Use Household Water Efficiently
A toilet that leaks or runs continuously might waste as much as 200 gallons of water per day, although the average family consumes just 70 gallons of water. Take, for example, high-efficiency toilets, which consume 1.6 gallons or less of water every flush or less. The use of new, high-efficiency washing machines and showerheads can also help to reduce water waste, which will relieve the load on your septic system.
Properly Dispose of Your Waste
Your septic system is responsible for disposing of everything that goes down your drains and toilets. One easy rule of thumb is to never flush anything down the toilet other than human waste and toilet paper, unless it is absolutely necessary. That implies you should never flush the following items down the toilet or drop them down the sink drain:
- Cooking grease or oil, baby wipes or wet wipes, dental floss, diapers, feminine hygiene products, cigarettes, cat litter, and paper towels are all examples of items that fall into this category.
Maintain Your Drainfield
The drainfield of your septic system is a component of the system that eliminates waste from the septic’s liquid. You should take steps to keep it in good condition, such as:
- Never park or drive your vehicle on your drainfield. Don’t ever put trees near your drainage system. Maintaining a safe distance between your drainfield and roof drains, sump pumps, and other drainage equipment

A septic tank or septic pump tank can range in price from $350 to $14,000, depending on the material used and the size of the tank. In most home situations, you won’t have to spend more than $3,000 on the tank’s actual construction. The majority of big, high-priced units are intended for use in apartment buildings or as part of a communal sewage system.
Concrete Septic Tank Cost
Concrete tanks range in price from $700 to $2,000. The total cost of installation ranges from $2,300 to $6,500. They’re one of the most often seen forms of installation. Despite the fact that they are vulnerable to cracking and separation, they are often resilient for several decades.
It’s critical to have it carefully inspected on a regular basis for cracks and runoff, among other things. Inspections and frequent cleanings will assist to extend its useful life. Your professional can tell you how frequently you should get it inspected, but it’s normally every one to three years.
Plastic and Poly Septic Tank Prices
Septic tanks made of plastic range in price from $500 to $2,500 on average, not counting installation costs. Plastic is a long-lasting, lightweight, and reasonably priced building material. They do not break as easily as concrete and do not rust. Because of their small weight, plastics are more susceptible to harm during the installation process.
Fiberglass Septic Tank Prices
Fiberglass septic tanks are typically priced between $1,200 and $2,000, not including installation. Fiberglass does not split or rust readily, but it is prone to damage during the installation process, much like plastic. However, because of its lighter weight, it is more prone to structural damage, and the tanks themselves can move in the soil.
It’s unlikely that you’ll ever see a new steel tank constructed. They will rust or corrode with time, no matter how well-made they are at the time. As a result, they are not permitted by many municipal construction rules, and you will only encounter them in existing installations. Steel is not a long-lasting material in the earth, and it is the least preferred.
Labor Costs to Install a Septic System
The cost of labor accounts for 50 percent to 70 percent of your overall expenses. Labor is typically more expensive than the tank itself in a normal installation, making it the most expensive option. For example, while the size required for a 3 to 4-bedroom home may cost between $600 and $1,100, the labor to install it might cost anywhere between $1,500 and $4,000.

A septic tank has an average lifespan of 20 to 30 years, however it may live anywhere from 14 to 40 years, depending on the following factors:
- What it is made of is a mystery. Concrete tends to require more maintenance, whereas commercial-grade fiberglass and plastic are known to last for decades in most environments. It’s amazing how well you’ve kept it up. Every one to three years, have your system inspected and pumped out
- Every three to five years, have it pumped out. It will depend on whether or not it gets vehicle traffic over the leach field. Driving over the leach field compresses it, which increases the likelihood of it failing. The soil’s chemical makeup is important. The length of time it may endure varies depending on the soil type and depth.
What are the signs I need a new septic tank?
There are a few indicators that it is time to replace your septic tank. These are some examples: If you smell sewage, you may have a solid waste problem in your septic tank that has to be dealt with immediately. Standing water: If there is no clear explanation for standing water, such as a significant rainstorm, it is possible that you have an oversaturated drain field, a damaged pipe, or a faulty septic system. A clogged septic tank will cause pipes to drain more slowly than they would otherwise be.
Construction on your home or the addition of more occupants will have an impact on your septic system.
pollution of nearby water: A septic tank leak can result in wastewater contamination, which can deposit nitrate, nitrite, or coliform bacteria in water sources around your property as a result of the leak.
If these bacteria are discovered in your vicinity, you should investigate your septic system to determine if it is the cause. Old age: If your septic system has reached the end of its useful life, it is time to replace it.
Does homeowners insurance cover septic systems?
Many unforeseen and abrupt repairs to septic tanks are covered by homeowners’ insurance policies. They do not, however, often cover harm caused by a failure to perform routine maintenance. Make certain that you are pumping and cleaning it on a yearly basis.
How much do septic system repairs cost?
Repairing a septic system can cost anything from $600 to $3,000. Most tank repairs and replacement parts cost less than $1500 for each type of repair or replacement part mentioned below. Leach fields range in price from $2,000 to $20,000.
