A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.
How deep should a septic pipe be?
A standard leach line is considered to be three (3) feet wide and three (3) feet deep with a length as required.
How deep is the septic tank outlet pipe?
After the solids settle out, effluent leaves the septic tank through the outlet pipe and flows to the drain field. The outlet pipe should be approximately 3 inches below the inlet pipe.
How long are the pipes in a leach field?
Local building codes also define setbacks from streams, wetlands, water supply lines, local water wells, and other potential obstacles. Typically, the pipes in your drain field run about 100 to 150 feet in length, although they can run longer. Pipes are often set 6 feet apart from each other as well.
How big is a septic tank drainage field?
Drainage fields must be a minimum of 10m from a watercourse, 50m from a water abstraction point and 15m from a building. They should also be sufficiently far away enough from any other drainage fields, mounds or soakaways so that the soakage capacity of the ground is not exceeded.
How deep are drain pipes buried?
The depth of sewer lines varies greatly. They can be as shallow as 12″ to 30,” or as deep as 6+ ft. Often times this is simply a matter of climate. In really cold climates, the pipe is buried deeper to prevent the pipe from freezing solid in winter.
What is the minimum depth for drainage pipe?
Pipes should be either: bedded on granular material, minimum 100mm deep, or. laid directly on the trench bottom, where the trench bottom can be accurately hand trimmed with a shovel but is not so soft that it puddles when walked on.
How deep is a septic tank inlet?
A typical septic tank has a 4-inch inlet located at the top. The pipe that connects to it must maintain a 1/4-inch-per-foot slope toward it from the house. This means that for every 10 feet of distance between the tank and the house, the inlet must be 2 1/2 inches below the point at which the pipe exits the house.
How far is the distribution box from septic tank?
The D-box is normally not very deep, often between 6″ and two feet to the top of the box. You may also see a pattern of parallel depressions, typically about 5 feet apart, that mark the individual drainfield leach lines. The D-box will at or near end of the drainfield area that is closest to the septic tank.
How far should drain field be from septic tank?
Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.
How many pipes are in a leach field?
Between four and nine lateral pipes run out of the distribution box and radiate outward in trenches to form the leach field. Since this is a gravity-based system, the lateral pipes must run at a downhill slope. Plastic septic chambers are placed over the leach line pipes.
What kind of pipe is used for septic drain field?
Corrugated pipe is typically used for drain fields. Septic systems use drain fields to treat the septic tank effluent for the removal of impurities and contaminants. The field is made up of trenches typically containing washed “drainrock” or gravel.
How do I know if my septic tank has a drainage field?
Some of the signs that your property has a septic tank are:
- The tank needing to be emptied each year.
- 2, 3 or 4 manholes in close proximity to each other above ground.
- Possible vent pipes above ground – these take unpleasant smells and gasses from the tank and distribute them into the air.
Department of Environmental Quality : About Septic Systems : Residential Resources : State of Oregon
In areas where houses and businesses are not linked to a municipal sewage system, a septic system is the most popular type of sewage treatment for those areas. When simplified to its most basic form, a septic system is comprised of two parts: a septic tank in which solids settle and decay and a drainfield in which liquid drained from the tank is treated by bacteria in the soil. Septic systems that are more sophisticated are constructed in places with high groundwater levels and/or poor soils.
Septic systems that are properly operating treat sewage in order to reduce groundwater and surface water contamination.

Before you buy
If the land is undeveloped, inquire as to whether the property has been examined for appropriateness for septic systems by either the Department of Environmental Quality or a local government contract agent, and if so, request a copy of the site evaluation report. The following are the questions you should ask:Has the site changed since it was last evaluated?
- Well construction, fill, roads, and other modifications can all have an impact on appropriateness. Is the land suitable for your development needs, taking into account the kind of system stated as acceptable on the report and the placement of the septic system that has been approved?
If the property has not yet been examined, you may choose to request that the present owner arrange for an evaluation to be done. Application for a site review can be made through either the Department of Environmental Quality or a local government contract agent. Before deciding to acquire the land, you must determine what sort of septic system will be necessary, as well as whether or not the permitted system site will fit your development requirements. Existing sewage treatment systems- If you are considering acquiring a home with an existing septic system, you should engage a trained inspector to assess the system before making the purchase.
- Is it true that the system was implemented without a permit? If not, it is possible that the system is very old (permits have been necessary since 1972, and in certain counties even earlier), or that it was unlawfully built. Systems that have been illegally developed may pose a threat to public health or produce pollution. In the future, you may be forced to upgrade or replace the system, and you may be held accountable and penalized if the system malfunctions or poses a concern to public health and safety. If your family or business has a large number of members, is the system the correct size to meet their needs? Permit documents often include information on the system’s capacity in gallons per day. Typical household water use is 450 gallons per day for a four-bedroom home. How old is the system, and has it been adequately maintained over its lifetime? Is there documentation demonstrating that the septic tank was pumped on a regular basis? Have there been any difficulties or complaints that have been brought to your attention in the past? It is possible that your local permitting agency has records of complaints or infractions that have not been addressed yet. Before you moved here, how many people lived in the house? Perhaps the approach works well with a single person but not so well with four individuals. Is the septic tank connected to all of the plumbing fittings
- And Is there evidence of a septic system failure, such as puddles over the septic tank or flooded drainfields? If the property is next to surface waterways, check to see that there are no direct discharges from the property. When it comes to septic system replacement, is there a suitable location if the existing system fails? In the event that there are any septic permit documents, they will show the replacement area that should still be “laid aside” for this purpose. What is the role of a qualified inspector? Some septic installers and pumpers have received training in the inspection of existing systems, while others specialize in the installation of new septic systems or pump tanks, as appropriate. Certified maintenance providers may also have the qualifications of a qualified inspector. The goal is to find out what their credentials are in septic system assessments (as opposed to only septic tank evaluations), as well as to obtain some recommendations. Verify the credentials of the references before hiring a contractor.
Signs of septic system failure
- Pools of water or wet places, unpleasant aromas, and/or dark gray or black soils in the vicinity of your drainfield are all signs that something is wrong. Water from the sewer overflows into the lowest drains in the home. The sound of drains gurgling and poor draining (first check for obstructions)
- Soapy flows onto the ground surface, into ditches, or into surface waterways It is impossible to mow over the drainfield because the earth is too soft.
Installing a new system
In order to have a new septic system installed, a two-step procedure must be followed. 1. Submit an application for a site review. The tests pits you give on your property will be evaluated by a DEQ or county agent, who will decide the size and kind of septic system that will be required, as well as the placement. 2. Submit an application for a building permit. For application forms, contact your local DEQ office or county agent, or you can obtain DEQ application forms from this website. There is a cost for both the site appraisal and the issuance of the building permit.
Maintaining septic systems
By having your septic tank tested for solids accumulation on a regular basis, you may prevent having to pay for expensive repairs. When the solids buildup in your septic tank exceeds 40%, you should have it pumped by a pumper who is licensed by the DEQ. For advice on how often to get your septic tank examined, contact the Department of Environmental Quality. Maintaining the condition of your septic tank on a regular basis (every 5 to 7 years) and checking for solids accumulation will save you money on costly repairs.
When the solids buildup in your septic tank exceeds 40%, you should have it pumped by a pumper who is licensed by the DEQ. If you follow the basic septic system DO’s and DON’Ts, a properly designed and maintained system may survive for a very long period.
Alternative Septic Systems For Difficult Sites
This Article Discusses Mound Systems are a type of system that is used to build mounds. Alternative Systems are also available. View and post commentsQuestions Septic System FAQsView all articles on the SEPTIC SYSTEM If your lot does not pass the perc test, some towns may enable you to construct an engineered system as a backup plan if the perc test fails. For waterfront estates and other ecologically sensitive places, alternative water-treatment systems may also be necessary to aid in the protection of water supplies.
- A “mound” system operates in much the same way as a normal system, except that the leach field is elevated above the natural grade.
- They require more frequent monitoring and maintenance in order to avoid complications.
- It is possible that the technology will not operate as planned if either the designer or the installer is inexperienced with the technology.
- The design of a system is particular to the soil type, site circumstances, and degree of consumption that is being considered.
- Some states and municipalities will only accept system types that have been certified in their jurisdiction, and they may also demand that the owner maintain a service contract with a vendor that has been approved by the state or municipality.
MOUND SYSTEMS
Mound systems are often two to three times more expensive than ordinary septic systems, and they need more frequent monitoring and maintenance. To see a larger version, click here. Ohio State University Extension provides the following information: The mound is comprised of a network of tiny distribution pipes that are embedded in a layer of gravel on top of a layer of sand that is normally one to two feet deep. Topsoil is applied to the tops and sides of the structure (see illustration). A dosing chamber (also known as a pump chamber) is included in a mound system, and it is responsible for collecting wastewater that is discharged from the septic tank.
Most feature an alarm system that notifies the owner or a repair company if the pump fails or if the water level in the tank increases to an unsafe level.
Aside from that, monitoring wells are frequently placed to keep track on the conditions inside and outside the leach field.
The most expensive items are the additional equipment, as well as the earthwork and other materials that are required to construct the mound.
In extreme cases, a mound system can cost more than $20,000 in some locations. Additionally, owing of the increased complexity, mound systems need more regular pumping as well as additional monitoring and maintenance. In certain cases, annual maintenance expenditures may exceed $500.
OTHER ALTERNATIVE SEPTIC SYSTEMS
Sand filters that do not have a bottom are frequent on coastal properties and other ecologically sensitive places. There is a large variety of alternative septic systems available on the market, with new ones being introduced on a regular basis. Some are designed at community systems that serve a number of houses, and they are often monitored and maintained by a professional service provider. Some alternative systems are well-suited to particular houses, albeit the costs, complexity, and upkeep of these systems must be carefully evaluated before implementing them.
Before the wastewater reaches the leach field, which serves as a miniature replica of a sewage-treatment plant, some larger community systems employ pre-treatment to reduce the amount of bacteria present.
There are numerous other versions and combinations of systems and components that may be employed, including the following:
- Pressurized dosing: This method makes use of a holding tank and a pump to drive effluent through the distribution pipe in a more uniform and regulated manner, hence boosting the effectiveness of the leach field. When used in conjunction with other techniques, such as a mound system, a sand filter, plastic leach fields or drip irrigation, it can be used to rehabilitate a leach field
- However, it should not be used alone.
- Septic system with alternative leach field made of plastic: This is a normal septic system with an alternative leach field that may be shrunk in some jurisdictions, making it ideally suited for tiny construction sites. Because the half-pipe plastic chambers provide a gap for effluent flow, there is no need for gravel in the system. Infiltrator System, for example, has been in service for more than two decades and, according to the manufacturer, can withstand traffic volumes with only 12 inches of compacted cover. The higher cost of the plastic components is somewhat countered by the lower cost of gravel and the smaller area of the drain field, respectively.
- Sand filter: This is a big sand-filled box that is 2-4 feet deep and has a waterproof lining made of concrete or polyvinyl chloride (PVC). Using filtration and anaerobic microorganisms, the sand is utilized to pre-treat wastewater before it is discharged into the leaching field. The boxes are often partially or completely buried in the ground, although they can also be elevated above ground level as necessary. While a pump and controls are typically used to equally administer the effluent on top of the filter, gravity distribution is also viable in some instances. The most common setup is shown in Figure 1. A collection tank at the bottom of the tank collects the treated effluent, which is either pumped or gravity-fed to the drain field. Some sand filters recycle the effluent back to the tank multiple times before discharging it into the drain field, while others do not. The majority of sand filters are used for pre-treatment, although they can also be utilized as the primary treatment in certain situations. A “bottomless sand filter” is used in this situation since the effluent drains straight into the soil underneath the filter (see photo above). A well designed and manufactured sand filter that is regularly maintained will prevent sand from being clogged on a consistent basis. More information about Sand Filters may be found here.
- Aerobic treatment system: These systems treat wastewater by the use of an aerobic process, which is normally carried out in an underground concrete tank with many chambers. Aeration, purification, and pumping of the effluent are all accomplished through the use of four chambers in the most complicated systems. The first chamber functions similarly to a smaller version of a regular septic tank in its function. An air pump is employed in the second “treatment” tank to ensure that the effluent is continually injected with fresh air. The presence of oxygen promotes the growth of aerobic bacteria, which are more effective in processing sewage than the anaerobic bacteria found in a standard septic system. It is possible to utilize a third and fourth chamber in certain systems to further clarify the water and to pump out the purified water. In addition, so-called “fixed-film” systems make use of a synthetic media filter to help the bacterial process go more quickly. In the correct hands, aerobic systems may create better-quality wastewater than a typical system, and they may also incorporate a disinfectant before the purified wastewater is discharged. A smaller drain field may be used in urban areas while a larger area may be sprayed across a whole field in rural areas. Technically speaking, they are tiny sewage treatment plants rather than septic systems, and they rely mostly on anaerobic treatment to accomplish their goals. They are referred to as ATUs in some circles (aerobic treatment units). Installation and maintenance of these systems are prohibitively expensive
- As a result, they are mostly employed in situations where high-quality treatment is required in a small area or with poor soils. A growing number of them are being built on beachfront sites. More information about Anaerobic Treatment Systems may be found here.
- Using a pump, wastewater is sent via a filtering mechanism and onto an array of shallow drip tubes that are spaced out across a vast area for irrigation. In order to send reasonably clean water to the system, a pretreatment unit is often necessary. Alternatively, the water may be utilized to irrigate a lawn or non-edible plants, which would help to eliminate nitrogen from the wastewater. This sort of system may be employed in shallow soils, clay soils, and on steep slopes, among other conditions. Frozen tubes can pose problems in cold areas since they are so close to the surface of the water. Expect hefty installation fees, as well as additional monitoring and maintenance, just as you would with other alternative systems.
- Wetlands that have been constructed. These are suitable for those who are environmentally conscious and wish to take an active role in the recycling of their wastewater. They may be used in practically any type of soil. An artificial shallow pond is used in the system, which is lined with rock, tire chippings, or other suitable medium and then filled with water. A pleasant atmosphere is created by the media, which serves as a habitat for particular plants that process wastewater and maintain the ecosystem. Wastewater from the septic tank is dispersed across the media bed through a perforated conduit, where plant roots, bacteria, and other microorganisms break down the contaminants in the water. The treated water is collected in a second pipe located at the back of the marsh. Household members must budget time for planting, pruning, and weeding in the wetlands area.

Septic Services
Pumping the leach field on a regular basis, as indicated by the manufacturer, can significantly extend its life. The typical life span of a leach field is roughly 20 years, depending on the conditions. When a leach field fails, the expense of replacing it is around $10,000. It is far less expensive to have your tank maintained correctly and to extend the life of the field than it is to pay for a new leach field, both financially and environmentally. If your home is equipped with a garbage disposal, the life of your septic tank and field might be reduced by half.
- If your home is equipped with a water softener, it can also significantly reduce the life of your septic tank and field.
- Please do not drive over the leach field as this may cause the pipes to be crushed and the drainage of water to be impeded.
- This also applies to the pipe that runs from the home to the tank, as well as the pipe that runs from the tank to the leach field.
- Grass aids in the prevention of erosion as well as the absorption of water by the ground.
- The lid can be anywhere between the level of the water and 6 feet below the surface.
- The homeowner does not want to dig more than 1-2 feet every time the tank is pumped or pay Arne’s to dig, in which case we would gladly build a well riser at no additional cost to him or her.
The risers are sold in increments of one foot. The riser’s proximity to the ground’s surface increases the ease with which it may be reached and pumped. Arne’s is a qualified contractor that is capable of installing both risers and tanks.
Septic and Wells
No one wants to flush a toilet down the toilet into a public drinking water supply. It is critical to correctly build and maintain septic systems in order to prevent groundwater contamination. A typical septic system is composed of three components:
- Domestic wastewater is collected and held in a septic tank, which can be made of concrete (concrete or metal), plastic (plastic) or fiberglass (fiberglass). Solids that float to the top of the tank or settle to the bottom are stored in this tank. The remainder of the liquid is discharged into the drainfield. It is possible that floating sediments will overflow into the drainfield and block pipes and soil if tanks are not pumped on a regular basis. In a drainfield, the liquid is dispersed across a large area through a network of pipes that are connected in a grid configuration. In the pipe, there are holes that enable liquid to leak into the earth. Proper soil: The soil is the most crucial purification phase in a septic system, and it is also the most difficult to achieve. Air and time are required for soil microorganisms and plant roots in order to break down bacteria, viruses, and nutrients, as well as to filter liquid waste. Septic systems fail when soils become too moist, blocked, or compacted to absorb liquids, or when soils become too well-drained to allow for sufficient time for liquids to be purified.
Septic System Maintenance
It is not true that septic systems are maintenance-free, contrary to common notion (or wishful thinking). Poor maintenance is the root cause of half of all septic system failures. Back-ups in the plumbing, thick grass over the drainage field, and odorous seepage are all indications of carelessness. This means that the system may discharge untreated sewage into the groundwater and into your well long before you see any of the above indicators!
To extend the life of your septic system:
Annual inspection of the solids in the septic tank is recommended. To check the tank lid, insert a probe into the inspection port located on the lid. Pump the tank if solids (typically blackspecks) cover the probe for more than one-third of the tank’s depth or if it becomes necessary to pump. Every 1 to 5 years, the tank should be pumped. Pumping frequency should be determined depending on the amount of solids present, or the chart below can be used as a reference. If you use a waste disposal, you’ll need to pump your tank more frequently.

Learn how much it costs to Install a Septic Tank.
Septic tanks range in price from $3,157 to $10,367, or an average of $6,743. 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.
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:
- In most cases, a new typical anaerobic septic system will cost between $2,000 and $10,000. $8,000 to $20,000 for an aerobic system. 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 leachfield. Three major components make up a septic system:
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.

- And a perc test costs $700–$1,300 Approximately $1,500 to $4,000 in labor costs. It costs $500 to $2,500 to install a septic tank
- Excavation: $1,200–$4,500
- Building permits: $400–$2,000
- Perc test: $700–$1,300
- Labor costs range between $1,500 and $4,000
- The cost of septic tank material ranges from $500 to $2,000.
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 System
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.
Chambered System
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.
Drain Field Replacement Cost: $7,500.
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.
Steel
Average costs for fiberglass septic tanks range from $1,200 to $2,000, excluding installation costs. It does not shatter or corrode readily, but it is prone to harm during installation, much as plastic is during transport and storage. As a result of its lighter weight and greater vulnerability to structural damage, the tanks themselves can move in the soil underneath them.
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.

FAQs
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 care, but commercial-grade fiberglass and plastic are known to survive 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?
What it’s comprised of and how it functions. Concrete tends to require more upkeep, although commercial-grade fiberglass and plastic are known to persist for decades in most situations. Your ability to keep things looking well. Every 1 to 3 years, have your system inspected and pumped out, and every 3 to 5 years, have it pumped out again. Is there any vehicle traffic across the leach field as a result of this? It is possible that driving over the leach field will cause it to fail. What is the soil’s chemical composition?
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.
- Tank Pumps cost between $800 and $1,500. A septic tank that is placed below the drain field may necessitate the installation of a pump to transport wastewater to the drain field. Pumping costs between $300 and $600 per year. Pumping is required to remove solid waste from even a perfectly functioning system every two or three years, even if it is in good working order. Tank Lids cost between $100 and $300 to purchase and install. If you purchase the lid and attach it yourself, it will cost you between $50 and $150
- Tank Lid Risers range in price from $300 to $1,000. Deeply submerged tanks can have their lids raised to the surface by using these devices.
Still Have Questions About Septic Tanks?
$800-$1,500 for a tank pump (depending on the model). Depending on the location of the septic tank in relation to the drain field, a pump may be required in order to transport wastewater up to the drain field. Pumping costs $300-$600 per year on an annual basis. In order to eliminate the solid waste, even a fully functioning system will require pumping every two or three years. Purchase and installation of a tank lid will cost between $100 and $300. If you buy the lid and attach it yourself, it will cost you only $50-$150.
In the case of heavily underground tanks, they elevate the lid level to the surface.
Additional Resources for What is a Septic System?
According to the Massachusetts Department of Environmental Protection, a properly maintained septic system should be pumped out at least once every three years! Regular maintenance is the most crucial factor in ensuring that your septic system is in good working order. Pumping on a regular basis helps to keep particles from leaking into the drainfield and blocking the soil pores. While the frequency of pumping depends on the amount of consumption, the Massachusetts Department of Environmental Protection advises that systems be pumped at least once every three years for households without a trash disposal.
- The frequency with which you pump should be determined by the amount of water that has accumulated and the amount of water that has been pumped in the past.
- It is astounding how many system owners assume that if they have not experienced any difficulties with their systems, they do not need to pump out their tanks.
- Solid materials sink to the bottom of the tank when your system is utilized, resulting in the formation of a sludge layer.
- In most cases, correctly engineered tanks have adequate room to safely store sludge for up to three to five years at a time.
- As the amount of sludge in the system rises, more solid wastes are allowed to escape into the soil absorption system (SAS).
When hiring a pumper, be certain that they are licensed by the local Board of Health, and always insist on receiving a paid receipt from the pumper that clearly outlines the terms of the transaction and the amount you paid (how many gallons were pumped out of the tank, the date, the charges, and any other pertinent results).
Keep a copy of this receipt as proof of purchase. In addition, a copy of this report is forwarded to the local Board of Health by the pumper.
Additional Resources for How often should I pump out my septic system?
- Once every 3 to 5 years, have the system examined and pumped out. If the tank becomes overburdened with sediments, the wastewater will not have enough time to settle before it overflows down the drain. After that, the extra solids will be carried to the leach field, where they will block the drain pipes and the soil. Always know where your septic system and drain field are in relation to your house and keep a detailed record of all inspections, pumpings, repairs, contract or engineering work for future reference. Keep a sketch of it on hand for when you go to the service center. The drain field should be planted above the septic system with grass or small plants (not trees or bushes) to help keep the system in place. Controlling runoff through imaginative landscaping may be an effective method of reducing water consumption. Install water-saving devices in faucets, showerheads, and toilets to limit the amount of water that drains into the septic system and into the environment. Replace any dripping faucets or leaking toilets, and only use washing machines and dishwashers when they are completely full. Avoid taking long showers. Roof drains as well as surface water from roads and slopes should be diverted away from the septic system. Maintain a safe distance between the system and sump pumps and home footing drains as well. Take any remaining hazardous substances to a hazardous waste collection station that has been approved by the local government. Use bleach, disinfectants, drain and toilet bowl cleaners sparingly and in line with the directions on the product labels. Only utilize septic system additives that have been approved for use in Massachusetts by the Massachusetts Department of Environmental Protection (MassDEP). In Massachusetts, it has been found that the additives approved for use have no detrimental effect on the particular system or its components, or on the environment in general.
- Non-biodegradables (cigarette butts, diapers, feminine items, and so on) and grease should not be disposed of down the toilet or sink. The use of non-biodegradable materials can clog the pipes, and grease can thicken and block the pipes as well. Cooking oils, fats, and grease should be stored in a container and disposed of in the garbage
- Paint thinner, polyurethane, antifreeze, insecticides, certain dyes, disinfectants, water softeners, and other harsh chemicals should all be added to the system to ensure that it works properly. Septic tank malfunctions can be caused by the death of the biological component of your septic system and the contamination of groundwater. Typical home cleaners, drain cleaners, and detergents, for example, will be diluted in the tank and should not do any damage to the system
- And Make use of a garbage grinder or disposal that drains into the septic tank to eliminate waste. If you do have one in your home, you should use it only in extremely limited circumstances. The addition of food wastes or other solids lowers the capacity of your system and increases the frequency with which you must pump your septic tank. If you utilize a grinder, you will have to pump the system more frequently. Trees should be planted within 30 feet of your system, and vehicles should not be parked or driven over any section of the system Tree roots may block your pipes, and heavy cars may cause your drainfield to collapse
- However, you can prevent this from happening. You should not allow anybody to work on your system or pump it without first ensuring that they are licensed system specialists
- Wash an excessive number of loads of clothing in your washing machine. Doing load after load deprives your septic tank of the time it needs to properly process wastes and causes the entire system to become overwhelmed with surplus wastewater. As a result, you might be overflowing your drain field without giving yourself enough time to recover from the inundation. To calculate the gallon capacity and the number of loads per day that may be safely pumped into the system, you should speak with a tank specialist. Cleaning the plumbing or septic system using chemical solvents is recommended. Microorganisms that devour toxic wastes will be killed by “miracle” chemicals that have been developed. These items have the potential to pollute groundwater as well.
Key Actions for Septic System Do’s and Don’ts
Septic systems that have been properly maintained can assist in preventing the spread of disease and other illnesses. System failures can have serious consequences.
- Your failure to maintain your water system could pose a serious health hazard to your family and neighbors, degrade the environment, particularly lakes, streams and groundwater, reduce the value of your property while also being extremely expensive to repair
- And put thousands of water supply users at risk if you live in a public water supply watershed and fail to maintain your system.
Keep an eye out for the following warning signals of a malfunctioning system:
- Surface sewage over the drainfield (particularly after storms)
- Sewage backups in the home
- Lush, green vegetation over the drainfield sewage smells
- Toilets or drains that are difficult to empty
If your system fails, the first thing you should do is call your local board of health, which must authorize all modifications and the majority of repairs before they can be carried out or installed. The board of health will inform you of the steps that must be taken. In the event that your system fails, call your local Board of Health immediately!
Key Actions for Failing Septic Systems Can Be Hazardous to Your Health
| Medium: Averages $2,000-$5,000; Runs $4,000-$12,000 in Higher Cost Areas | Enhanced System: $10,000-$20,000+ |
- The cost of installing or rebuilding a traditional septic system (including the tank) is from $2,000 to $5,000 in the Midwest, but can range from $4,000 to $12,000 or more in locations with higher material and labor costs. Septic systems that are designed, engineered-like or alternative septic systems, such as mounds, soil/peat filters, aerobic systems, and/or artificial wetlands, can cost $10,000 to $20,000 or more, according to the Rhode Island Regional Water Quality Program. These alternative septic systems perform better than the conventional technique in areas with high groundwater levels or soil that is slowly or fast percolating, as well as in areas near drinking water supplies, wetlands, coastal ponds, or other water resources. Simply installing a septic tank will cost between $500 and $1,800 based on its size (varying from 300 to 1,000 gallons) and kind. It costs an additional $100-$200 to purchase piping and other necessary supplies
- New Mexico State University gives an overview of the septic tank installation process. Many locations, however, require that a septic system be planned and constructed by experienced and licensed experts
- For more information, contact your local or state sanitation agency.

What should be included:- It is necessary to employ Septic systems when sewage treatment plants are not accessible, which is typically the case in rural or suburban areas with big lots. Essentially, a septic tank is a huge, underground, waterproof container that can be constructed of concrete, fiberglass, or plastic (polyethylene). An explanation of how septic systems function and where they might be utilized can be found at the North Carolina State University Ag Extension
- Installing or replacing a septic system might take anything from a few days to a week or more. The procedure entails substantial excavating, which is frequently accomplished using powerful earth-moving equipment.
- The majority of counties and states require a construction permit for the installation or replacement of a septic system, which may cost anywhere from $250 to $1,000 or more depending on the location and complexity of the job. For further information, contact your local building and planning department. A septic system installation typically entails substantial digging and damage to the landscaping
- New grass and other plantings can cost anywhere from $100 to $1,000 or more.
- Unlike individual septic tanks, each house has its own underground septic tank, but all of the septic tanks are connected to a single drainfield, leachfield, or soil absorption system. A cluster septic system, which is often implemented by developers, distributes the expense of drainfield installation and maintenance across a large number of dwellings.
- To find out if your local sanitation agency maintains a list of licensed septic installation firms, contact them and ask. Onsite wastewater recycling contractors can be found by contacting the National Onsite Wastewater Recycling Association for recommendations. Inquire about training and previous experience. Check to see if the firm is legally bonded, insured, and licensed in your jurisdiction.

A perc or perk test in Northern Va from a licensed consultant will cost between 1200-2500 dollars depending the district and county fees. Fairfax County costs are 2-4x as much due to local health dept bureaucracy and redtape requiring a surveyor and engineer to be used for any certification or permitting. Real costs of conventional systems (3-4 bedrooms) are from 14-25k depending on the soil percolation results and whether or not a pump is required. If the system is an alternative (BAT in MD) the design costs add 1000-2500 in costs and the installation of the specialized equipment adds costs that can total 20-35,000 easily.
Your property is the most valuable asset you will own so be careful with the land you contract to purchase and beware not all property is equal in value for development.
