- Determine the type of soil on the lot by digging a two 5 foot holes where your field is to be situated Find out what type of septic system, if any, will work on those soils. Obtain a cost estimate for installing the kind of septic system you need.
Is it safe to drive over a concrete septic tank?
Can You Drive on a Septic Drain Field? No, driving over your septic drain field is similarly never ever recommended. As much as you are able to help it, prevent cars or heavy equipment (such as oil delivery trucks, swimming pool water trucks, cement mixers, and also the like) to drive straight over the field.
How do you build a septic tank drain field?
Place a thick layer of gravel at least 1 foot deep along the entire length of the trench. One and a half feet of gravel would be better. Place perforated pipe into the trench on top of the gravel and, using a clamp, attach the pipe to the septic tank drain.
Can I put pavers over septic tank?
You can’t build a paver patio on top of a septic tank, and doing so could be against the planning laws of your state or local area. Septic tanks can take very little weight without getting damaged, and you’ll also need access to the tank in the future too. You shouldn’t build a deck on one either.
Is it normal for snow to melt over septic tank?
Generally speaking – melted snow over your septic tank is probably not a cause for concern. It’s actually a good sign that there is heat rising to the ground level – it shows that your tank is working right and it’s breaking down the solids.
How do I connect two septic tanks together?
Use a 4-inch pipe to connect the two septic tanks. Place this pipe into the inlet hole of your new septic tank before you lower it into the ground. After you’ve lowered your new septic tank, insert the other end of the pipe into your old septic tank’s outlet hole.
How is septic tank constructed?
Septic tank Consists of Top Slab, Bottom Slab with PCC Bed, Shear walls around the tank and a top cover (Opening) to check the level of Waste water.
How much does it cost to pump a septic tank?
How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.
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 big of a septic tank do I need?
The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank. On the other hand, a bigger home of approximately 2,500 square feet will need a bigger tank, more than the 1,000-gallon range.
Can I install my own leach field?
You may also need to pull a permit to put in a new leach field. A leach field is an important part of a septic system. It disperses fluid from the septic system over a large area of soil adjacent to the building it services. Building your own leach field is physically difficult, but it can save you lots of money.
How big should a septic drain field be?
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.
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.
Septic tank found under driveway – what are my options?
I’m not really sure what is going on with the OPS. According to the description, he is “taking a look at a house.” Is it to make a purchase, perhaps? If the OPS is considering acquiring the house, he will, of course, want a thorough assessment of the septic system to ensure that it is in conformity with all applicable laws and regulations. I’m not sure where the OPS is located, but where I live (Massachusetts), a septic system examination is required and must be paid for by the home’s owner before the house can be sold.
Again, I have no clue where the Office of Public Safety is situated, but the Board of Health is the best location to begin your search for septic system installation data.
Because it was clear from what was described about the process that the first three companies had no idea where the tank was, it is reasonable to assume that either there are no plans on file, or that they failed to review the plans before beginning their search, or that the plans on file were not accurate.
The statement that any tank under a driveway must be engineered to sustain the weight of a vehicle, and not only of a car but of a heavy load such as a dump truck, is correct in this instance.
It is probable that your local regulations may differ.
If there are any plans on file, have a look at them.
Instruct the inspector to create a documented cost estimate for bringing the system into conformity with current industry regulations.
Septic Tank Driveway
This residence was purchased around three years ago. It was constructed in 1993. The tank is located around 8 feet from the back of the house, precisely beneath the gravel path leading to the basement garage and workshop. The gravel path leading up to the front of the home is on the other side of the tank. I’m starting to be concerned about cracking this tank open. My kid is currently parking his modest car in the basement garage, which he built himself. Due to the fact that the cement cover had been shattered the last time I had it pumped out, I placed a 1/2 steel plate over the access hole (another stupid move on my part, I should have used aluminum).
- My question is whether there is a method to pour a “bridge” or something similar over the tank to allow us to drive automobiles across it.
- As a result, I was septic-illiterate when I purchased the house, and it didn’t occur to me that I could have an issue until later.
- I’m not even going to mention the location of my drain field.
- I think that could work, but I’m having trouble getting passed the riser concept.
Because the tank is around 2.5 feet deep, I don’t mind scooping dirt and gravel out of the cover.
Septic Tank Installation and Pricing
To process and dispose of waste, a septic system has an underground septic tank constructed of plastic, concrete, fiberglass, or other material that is located beneath the earth. Designed to provide a customized wastewater treatment solution for business and residential locations, this system may be installed anywhere. Although it is possible to construct a septic tank on your own, we recommend that you hire a professional to do it owing to the amount of skill and specific equipment required.
Who Needs a Septic Tank?
For the most part, in densely populated areas of the nation, a home’s plumbing system is directly connected to the municipal sewer system. Because municipal sewer lines are not readily available in more rural regions, sewage must be treated in a septic tank. If you’re moving into a newly constructed house or onto land that doesn’t already have a septic tank, you’ll be responsible for putting in a septic system on your own.
How to Prepare for Your Septic Tank Installation
Here are a few pointers to keep in mind to make sure your septic tank installation goes as smoothly as possible.
Receive Multiple Estimates
Receiving quotations from licensed septic tank installers and reading reviews about each firm using trustworthy, third-party customer evaluations should be done before any excavation or signing of any paperwork is done. Examine your options for a contractor and make sure they have the appropriate insurance and license, as well as the ability to include critical preparations such as excavation and drain field testing in their quotation.
Test the Soil and Obtain a Permit
For septic systems to function properly, permeable soil surrounding the tank must absorb and naturally handle liquid waste, ensuring that it does not pollute runoff water or seep into the groundwater. The drain or leach field is the name given to this region. Before establishing a septic tank, you are required by law to do a percolation test, sometimes known as a “perc” test. This test indicates that the soil fits the specifications established by the city and the local health agency. In most cases, suitable levels of permeable materials, such as sand or gravel, are necessary in a soil’s composition.
Note: If you wish to install a septic tank on your property, you must first ensure that the ground passes the percolation test.
Plan for Excavation
Excavation of the vast quantity of land required for a septic tank necessitates the use of heavy machinery. If you are presently residing on the property, be careful to account for landscaping fees to repair any damage that may have occurred during the excavation process. Plan the excavation for your new home at a period when it will have the least influence on the construction process if you are constructing a new home.
Typically, this occurs before to the paving of roads and walkways, but after the basic structure of the home has been constructed and erected. Adobe Licensed (Adobe Licensed)
The Cost of Installing a Septic Tank
There are a few installation charges and additional expenditures connected with constructing a new septic system, ranging from a percolation test to emptying the septic tank and everything in between.
A percolation test can range in price from $250 to $1,000, depending on the area of the property and the soil characteristics that are being tested. Ordinarily, specialists will only excavate a small number of holes in the intended leach field region; however, if a land study is required to identify where to excavate, the cost of your test may rise.
Building Permit Application
A permit will be required if you want to install a septic tank on your property. State-by-state variations in permit prices exist, however they are normally priced around $200 and must be renewed every few years on average.
Excavation and Installation
When you have passed a percolation test and obtained a building permit, your septic tank is ready to be professionally placed. The cost of a new septic system is determined by the size of your home, the kind of system you choose, and the material used in your septic tank. The following is a list of the many treatment methods and storage tanks that are now available, as well as the normal pricing associated with each.
Types of Septic Tank Systems
Septic system that is used in the traditional sense Traditionally, a septic system relies on gravity to transport waste from the home into the septic tank. Solid trash settles at the bottom of the sewage treatment plant, while liquid sewage rises to the top. Whenever the amount of liquid sewage increases over the outflow pipe, the liquid waste is discharged into the drain field, where it continues to disintegrate. This type of traditional septic system is generally the most economical, with an average cost of roughly $3,000 on the market today.
Drain fields for alternative systems require less land than conventional systems and discharge cleaner effluent.
Septic system that has been engineered A poorly developed soil or a property placed on an uphill slope need the installation of an engineered septic system, which is the most difficult to install.
It is necessary to pump the liquid waste onto a leach field, rather than depending on gravity to drain it, in order to ensure that it is equally dispersed across the land.
Types of Septic Tanks
- Concrete septic tanks are long-lasting and rust-proof, but they are difficult to repair if they are damaged. It is possible that concrete tanks will cost up to $2,000 depending on their size. Plastic —While plastic tanks are cost-effective, they are also susceptible to damage. They are around $1,200 in price. Fiberglass —While fiberglass septic tanks are more durable than their plastic counterparts, they are susceptible to shifting or displacement if the water table rises to an excessive level. Depending on the model, these tanks may cost up to $2,000
More information may be found at: Septic Warranty Coverage and Costs.
Using Your Septic Tank
It is important to maintain the area around your new septic tank’s drain field and to frequently check your tank using the lids included with it. Never use a trash disposal in conjunction with your septic tank since it might cause the system to clog. Additionally, avoid driving over the land where your septic tank is located or putting heavy gear on top of your septic tank or drain field to prevent damage. Most of the time, after five years of septic system use, you’ll need to arrange a cleaning and pumping of the system.
Consequently, there will be no accumulation of solid waste that will leach into the surrounding soil or groundwater. Send an email to our Reviews Team [email protected] if you have any comments or questions regarding this post.
r/HomeImprovement – looking to pave (asphalt) my driveway, but the septic tank is under there, anyone deal with this?
My house is situated on a narrow property that is approximately 75′ wide and 225′ long. My existing driveway is made of gravel and is in desperate need of repair. The driveway leads to a two-car detached garage at the rear of my home, which is around 150 feet away. I’d want to have an asphalt driveway built for my home. Having spoken to a former owner, I was advised that, while the septic tank is relatively recent (it was placed by the owner before him about 1990), it is located beneath the driveway around 15′ in front of the garage.
As a result, I have to presume that whomever erected the septic tank did so with the knowledge that it would be driven over, but I don’t want to jump to any conclusions just yet.
Is it necessary for me to contact a septic firm separately and have them analyze the situation?
I’m aware that there are access ports somewhere in my driveway that would need to be maintained, which is OK, but I’m more worried with being able to have an asphalt driveway constructed that is safe to use.
- Installation of a new septic tank
- Soil preparation
- And drywall.
- Backflow prevention, raised bed systems, and leach fields are all examples of best practices.
All of this is accomplished with minimal to no disruption to your yard or driveway.
New Septic Tank and Leach Field Installation
A percolation test is performed, in which water is put into three “presoaked” test holes measuring 6-12 inches in diameter, and the percolation rate (which is the rate at which the water level in the hole lowers as water is absorbed) is measured and documented. Following the percolation test, the size of the septic system to be constructed is decided in part by the “perc. rate,” which is multiplied by the number of bedrooms in a home, or, in the case of commercial systems, by predicted estimates of daily water consumption.
- Your property’s square footage
- The incline (steepness) of your property
- In relation to surface water and wells, the placement of your planned system is important. Land suitable for a leach field must be available for construction.
The permit application may include some or all of the following:
- Application forms that have been properly filled
- The findings of a site evaluation conducted by a qualified professional engineer, sanitarian, or installation
- The results of the site evaluation Plan of the property showing the dwelling or enterprise, roadways, wells, water lines, on-site sewage facilities, and other permanent features A floor plan indicating rooms and closets, as well as their measurements and the overall (heated) square footage of the dwelling or institution. There should be one or more designs for the planned design of the septic system (including the kind of tank and the leach field system)
- If the property is not in a subdivision, a map showing the location of the property is required. Identification of a replacement/secondary leach field area that will be used in the event of a system failure that is permanently reserved
Your local board’s acceptance or modification of permit
Your septic permit application will be reviewed by the Board of Health in your community. If your proposal is approved for construction of the system in line with the plans you provide, they will notify you of their decision following their examination of your application. Modifications to the proposed system designs that are judged required will frequently result in acceptance of the system design proposal. Instead of a typical leach field, the Board of Health may propose or require the use of an alternate system in certain circumstances.
Depending on the board’s review, modification criteria might include things like a raised bed or a bigger leach field.

The Dangers of Paving Over Septic System Components – Septic Maxx
When determining whether or not to build a septic system, there are a number of things to take into consideration. Do I put up a concrete septic tank or a plastic septic tank? My septic tank is too small. What size should it be? Is septic damage covered under my homeowner’s insurance policy? In addition to such queries, you should think about where you want to put the various components of your septic system. Contractors must take into account the existence of deep-rooted trees as well as regions prone to soil compaction before breaking ground on any construction project.
Homeowners have suggested paving over specific components of a septic system in an effort to conceal the system’s components. Here’s why it’s a poor idea to do so.
Paving Over Your Drain Field
Drain fields are hazardous in and of themselves, let alone when paving over them, which is extremely perilous. When you drive over or park in your drain field, you are interfering with appropriate evaporation and increasing the likelihood of soil compaction taking place. A situation in which the earth collapses as a result of excessive pressure nearly usually results in the crushing of pipework is called soil compaction. If you drive or park anything that is heavier than a child’s bike on or over a drain field, you will almost certainly incur expensive repair bills.
Consider placing a 4,000-pound automobile or a 6,000-pound truck on top of the pavement, just to be sure it isn’t already too heavy.
Unlike septic tank repairs, which can be completed by merely replacing the tank, drain field repairs need the replacement of the whole system, which can cost up to $10,000.
Paving Over Your Septic Tank
It is never a good idea to pave over your septic tank. Although soil compaction is not a big concern when it comes to septic tanks, there are additional risks associated with installing an unsecured septic tank below concrete or heavy vehicles. The usage of certain materials and structures is required for the safe paving of over septic tank areas. Due to the fact that the great majority of tank manufacturers do not include such safety elements in their septic tanks, they are more prone to bursting under pressure.
There have been occasions in which septic tanks have collapsed, resulting in significant damage or death.
Do not pave over septic tank components in order to maintain your own safety and the correct operation of your septic tank.
Implementing the usage of environmentally friendly septic tank additives from Septic Maxx will help to advance that endeavor.
Building Near and Over Septic Tanks
Posted on a regular basis In most cases, minimum setback rules imposed by the Texas Commission on Environmental Equality (TCEQ) preclude the building of a new residence from occuring over any point of an existing sewage disposal system. Foundations, pools, property lines, wells, and other structures must be kept at a certain distance from the septic tank and drainfield in order to meet these setback requirements.
It is possible that some homeowners will install objects such as patio decks or house additions over their systems, whether by accident or design. This might result in higher costs when it comes to locating and maintaining the system.
Building over septic tanks
Construction of a building over any section of your septic system is not recommended. The most typical issue we see is when someone wants to pump out their septic tank but is unsure of where their tank is situated on their property. Tanks hidden beneath a hardwood deck, pool patio, driveways, or even room extensions are not unusual for us to discover and investigate. The majority of the time, this occurs because the homeowner is uninformed of the tank’s location and/or does not have a plan in place for future tank maintenance.
However, in this scenario, the homeowner will be able to pump out their septic tank because no permanent constructions should be constructed over any component of the system.
Building over drainfields
In order for the drainfield to function, water in the solids and some evapotranspiration must be absorbed. In order for bacteria in the soil beneath a drainfield to treat wastewater from a drainfield, the soil beneath the drainfield must have sufficient oxygen. However, if a permanent structure is constructed over a drainfield, it has the potential to reduce the amount of oxygen that can be absorbed by the soil and hence reduce evapotranspiration. The potential of causing the drainfield lines to collapse is a significant concern when constructing over them.
Depending on the age of your system and the restrictions of your local authorities, repairing or shifting your drainfield may need the installation of a whole new system.

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.
When it comes to success with alternative systems, proper maintenance is essential.
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.
- 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.
