How To Build An Underground Septic Tank?

  • 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.

How deep should a septic tank be in the ground?

The general rule of thumb is that most septic tanks can be buried anywhere from four inches to four feet underground.

How big is an underground septic tank?

Underground septic tanks are available in sizes ranging from 200 gallons up to 1500 gallons. An inlet and outlet may be added to tanks sized 200 gallons to 500 gallons for $75.00.

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 deep are drain fields buried?

A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.

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.

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.

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 are the alternatives to septic tanks?

Alternative Septic Systems

  • Raised Bed (Mound) Septic Tank Systems. A raised bed drain field (sometimes called a mound) is just like what it sounds.
  • Aerobic Treatment Systems (ATS) Aerobic systems are basically a small scale sewage treatment system.
  • Waterless Systems.

What are the 3 types of septic systems?

Types of Septic Systems

  • Septic Tank.
  • Conventional System.
  • Chamber System.
  • Drip Distribution System.
  • Aerobic Treatment Unit.
  • Mound Systems.
  • Recirculating Sand Filter System.
  • Evapotranspiration System.

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.

How often does a 1000 gallon septic tank need to be pumped?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

How long does it take to pump a septic tank?

How long does it take to pump a septic tank? A septic tank between 1,000 – 1,250 gallons in size generally takes around 20-30 minutes to empty. A larger tank (1,500 – 2,000 gallons) will take about twice as long, between 45-60 minutes.

How long do septic tanks last?

A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.

How to Build a DIY Septic Tank 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.

Soil Classification

The Soil Conservation Classification System of the United States Department of Agriculture is the soil classification system that is utilized in practically all states in the United States today.

As you continue to examine down into the earth, you will see that most soil testing pits include three or more different types of soil.

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.

Drainfield Layout

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.

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.

  1. 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.
  2. 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.
  3. Toilets that conserve water nowadays utilize less than two litres of water every flush.
  4. It might be a lifeline for those who live in areas where septic treatment is not available.

Part 1 of 3: Cutting the Tanks

  1. 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. 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
  3. 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. 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
  1. 2Place the drum at the end of the trench, with one side hole drilled in it. When you place the drum on the floor, make sure it is level. Check to see sure the drum’s top is at least 4 inches (10 cm) below the surface of the water. 3 Dig a hole that is one foot (30 cm) deeper than the first to accommodate the positioning of the second drum in front of the first. In order to ensure a tight fit and prevent the drum from shifting, make your hole the same diameter as the drum you’re inserting in it. 4 The hole should be leveled with gravel until a 90-degree curve can be made to connect the top drum’s hole on one side to the toilet flange on the other. Check the alignment of the holes in the 90-degree bend between the two drums by dry fitting it between the two drums. If you need to improve the alignment of the pipe line, dig the hole a little deeper. 5 To make the bend, cut 31 2in (8.9 cm) pieces of ABS pipe and adhere them to the bend with epoxy or hot glue. With a hacksaw, cut the ABSpipe parts, also known as nipples. 6 Insert the pieces into the bend and hold them in place using PVC adhesive. Check the fit between the two drums to ensure that they are in alignment. Insert the end of the 21 2in (6.4 cm) nipple into the side hole of the first drum and tighten the nut. 7Glue the end of the 31 2in (8.9 cm) nipple into the toilet flange on the second tank, making sure that the nipple on the other end aligns with the hole on the top of the second drum. To hold the bent in place, apply PVC adhesive to the inside of the curve. Don’t be concerned about the link to the first drum just yet
  2. You’ll make that connection later. 8. Glue a Y-bend to a 31 2in (8.9 cm) nipple, and then bend the angled piece of the Y-bend at a 45-degree angle. Using your PVC adhesive, attach a nipple to the end of the Y-bend and let it dry. Assemble the Y-bend and align the angled pipe on it so it meets the incoming waste line, then glue it onto the toilet flange. 9 21 2in (6.4 cm) nipples are cut and glued to one end of the 45-degree bends at the bottom of the lower drum, and they are then inserted into the side of the lower drum. Directional bends are defined as those that are perpendicular to the bottom of the trench at their ends. Advertisement

Part 3 of 3: Connecting the Drain Pipes

  1. 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
  2. 3Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
  3. 4Place another stake approximately 37 8ft (1.2 m) down the trench from the first one
  4. 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
  5. 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)
  6. 5Repeat this method until you have stakes running the whole length of the trench
  7. 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
  8. 6Place gravel in the trench until the top of the gravel is level with the top of the stakes
  9. 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
  10. 7Place 20 ft (6.1 m) of perforated drain pipe into each hole on the second drum
  11. 8Place 20 ft (6.1 m) of perforated drain pipe into each hole on the third drum
  12. 9Place 20 ft (6.1 m) of perforated drain pipe into each hole on the fourth drum
  13. 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
  14. 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
  15. 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 can call a septic service to have it drained
  • If it doesn’t, you can do it yourself. Question What is the proper 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 piping system should be sloped at 2 percent, or 2.5 inches per 10 feet. Question Is it possible for this system to freeze in the winter? And could I include antifreeze in the mix as well? Antifreeze will kill the beneficial bacteria that are required for the process to function properly. The process is biological and will create some of its own heat. It could always be dug deeper to get some more 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).

Warnings

  • 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.

Septic tanks are big underground tanks that are typically used to treat sewage and household waste in rural regions where there is no underground sewer system. Septic tanks are typically placed in rural areas where there is no underground sewer system. Aeration tanks collect solid waste, which sinks to the bottom of the tank, and liquid waste, which runs off to an area designated for absorption by the soil. Septic tanks should be drained out at least once a year, if not more. The frequency with which this is required is determined by the number of persons that use the septic tank on a regular basis.

It is true that certain states mandate that septic tanks be built by a licensed professional.

  • Calculate the available capacity. Septic tank size is determined by the amount of people that will be living in the residence. You will need to talk with your installer in order to decide the amount of tank you require. Make a decision on the sort of tank to purchase. Septic tanks are available in a variety of materials, including steel, fiberglass, and reinforced concrete. Examine the many alternatives with your installer and choose which is the best fit for you. Find out where the place is. Your septic tank should be situated a short distance away from your home. This will allow you to take use of gravity between the home and the tank by having the waste run down the pipe into the tank
  • However, this will be more expensive. Excavate You may dig the hole for your tank by yourself if you want to save money. Determine the dimensions and precise location of the hole you will need to dig by speaking with your installer or with a structural expert before digging the hole. In addition, you will need to create a space for a pipe with a minimum diameter of 4 inches (10 centimeters) that will run from the house to the tank, with a drop of 14 inches for every 12 inches (30.5 centimeters) of pipe length (.64 centimeters). Along with the tank, you’ll need to install a conduit leading to the leach region, where the liquid waste will seep into the ground.

Building an Underground Bunker from Septic Tanks

Find out how much room you have. Septic tank size is determined by the amount of people that will be living in the residence. When determining the size of the tank, you will need to check with your installer. Pick up the type of tank you want to purchase. Steel, fiberglass, and reinforced concrete are all options for septic tanks. Examine the many alternatives with your installer and choose which is the most appropriate for you. Decide on a certain site Septic tanks should be placed at a little incline relative to the house.

Consult with your installer or a structural engineer to determine the exact dimensions and location of the hole that will need to be dug for the installation.

Along with the tank, you’ll need to install a conduit leading to the leach region, where the liquid waste will seep into the soil.

Can You Use a Septic Tank as a Storm Shelter or Bunker?

In a nutshell, the answer is yes. Of course, modifications to the tanks are required in order to enable underground life. Septic tanks are not a new concept; they have existed in some form or another for thousands of years in various forms. A concrete septic tank might be converted into a concealed subterranean bunker, according to this theory. Septic tanks are widely used and readily available, and the installation of these tanks does not create any concerns for bunker construction. This essay is written under the assumption of a completely new installation.

I’ll write this from the perspective of someone who constructs a septic tank under false pretenses but never uses it for the purpose for which it was designed.

This translates to the construction of a “secretbunker.” If you don’t want it created for you in this manner, you can simply avoid calling the plumbers to connect it to your home or company after the septic tank builders have finished their work.

Septic Tanks

When creating this hollow subterranean chamber, make certain that your septic tank possesses the following characteristics: 1. These should be typical, but make sure to discuss them with the contractors ahead of time. 1 – It has to be completely waterproof. This may appear to be paradoxical, yet examine the following facts. If groundwater is able to enter your tank, it is possible that the contents of your tank will be driven up and out the manhole after a strong downpour. You also do not want bacteria from the tank to be able to easily mingle with the groundwater surrounding your home.

  1. Because of this, septic tanks are often watertight; nevertheless, be certain that you and your builder are on the same page before proceeding.
  2. For the sake of this scenario, we will use the inlet and exit for ventilation as well as cables, and the manhole will serve as an entry.
  3. The first stage is mostly composed of solid materials, which settles to the bottom where it will be digested by bacteria over time.
  4. Water that has run off into a French drain can be filtered and treated further here, or it can simply be allowed to sink into the earth.
  5. 3 – The tank should be of sufficient size.
  6. The bare minimum, in my opinion, is a 12 × 12 foot foundation with an interior height of 7 feet.
  7. These silo-like structures are available in rectangular or spherical configurations.
  8. Always double-check that it’s watertight and won’t collapse under pressure.

Making it Survivable

In this case, I prefer to refer to it as making it “survivable” rather than “livable” because what we are constructing here is not a high-end subterranean bunker equipped with a flat-screen television and other expensive amenities often seen in professional, purpose-built bunkers. From this point forward, I am writing under the idea that the tank has been constructed, the builders have departed, and that you are now beginning the process of upgrading it to serve as a covert hiding and storage facility for WTSHTF.

Lock-ability

First and foremost, you will want entry into and out of the unit. This has to be done through the manhole cover. Check that the manhole is elevated above the surrounding area at all times. Flooding from runoff is something you want to avoid. Second, I would suggest a cover that is square in shape. Getting a hinge to fit on it will be much easier in the future, and once you are inside, closing and controlling the cover will be much easier as well. Locking the lid from both the inside and outside is required; however, make sure your lock system is designed in such a manner that you cannot be locked inside by someone from the outside.

Also, a sledge hammer and chisels, in case you need to demolish a passageway for any reason.

It should be self-evident that a secret subterranean bunker would have a non-obvious entrance to avoid being discovered.

An alternate solution would be to make it really clear. Everyone can see you because you’re right in their face. Take care not to draw attention to yourself when you enter or exit the bunker. Then you may rest assured that your secret is protected.

Build Access

The ladder system is the next step. A rope ladder is OK, and there is nothing wrong with doing so, but consider constructing a solid steel frame ladder that you can climb up and down without running the danger of it falling over. From this perspective, attempt to position your manhole cover near to the perimeter of the tank rather than in the middle of it. Another thing to think about is how you’re going to close that sucker once you’re inside. In my opinion, a platform that is solid enough to stand on while still allowing both hands to be free to manipulate the manhole cover is the best solution.

As a result, this is how things should go.

A series of steps or a slide will be required to bring you to the ground level from there.

HVAC – Heating, Ventilation, Air Conditioning.

You will also require air in order to avoid suffocating and dying. It will be a death bunker, rather than a survival bunker, as opposed to the former. Keep in mind that CO2 has a larger density than oxygen and will settle closer to the floor, while oxygen will settle closer to the top. This has ramifications for both the positioning of the bed and the ventilation system. Don’t let your children sleep on the floor. You can sleep in hammocks, bunk beds, or anything you like, but never on the ground.

  1. This is because you must ensure that all of your safety precautions are in place.
  2. Heating If you wish to install a carbon-based stove, my proposal is that it should have its own oxygen source that comes in from outside the house.
  3. Keep this in mind when purchasing a unit, and discuss it with the vendor before making a purchase.
  4. I would not, however, sleep with it on my person.
  5. This gets me to the second point I want to make.
  6. You may use a caulking gun to attach silicone or resin-based adhesives to the walls, and then cover the walls with polystyrene insulation panels to keep the heat in.
  7. Consider the use of cold-room panels.

In order to have the best acoustic performance, I would add one last layer of thin plywood or Masonite.

These tiny fellows are capable of running for hundreds of hours without experiencing any problems.

This means that you can simply power them with tiny solar panels or rechargeable batteries such as those found in your car.

The amount of airflow they will produce will be more than sufficient for human survival.

It is possible to connect a solar panel directly to the batteries if you have one in place.

If your PV system has an inverter, you will be able to operate your fans on 220V alternating current.

The majority of generators are also capable of charging batteries.

If you simply Google those two terms, you will be able to see exactly what I am referring about immediately.

When installing a drainage system outside your bunker, use 4′′ inch PVC or Flex-Drain pipe since it can be buried beneath the earth and run underground, making it difficult to detect the location of your bunker.

This only adds a layer of redundancy to the system.

In addition, make certain that insects are unable to obtain entrance.

In addition, you may construct your own by incorporating filters into the game.

The goal is primarily to keep pests out of the house.

Glue the PVC drain pipes together and use ducting tape to seal the interior of the system.

Consider them as more than just one line in and one line out, if that makes sense to you.

Take a look at the two scenarios that follow.

You’ll want to be able to remove air from the highest position feasible, allowing warm air to escape and the bunker to cool as quickly as possible.

You don’t want to lose any of the little heat you have left in your body.

As a side note, I’d want to point you that the warmer it is, the more all of these gases combine, so in the summer, everything is a huge mashup, and removing air out of the top of the bunker is a good idea.

Those with the greatest density are found near the bottom.

In terms of airflow, I believe that you just need one fan on a single line to accomplish your goals.

The same is true in the other direction.

If the lines are extremely lengthy, air friction may cause the air to get stagnant, in which case you should operate both fans at the same time.

Make certain to double-check.

Furthermore, affordable battery-operated gadgets that can monitor your degree of oxygenation by clamping over your finger are available; consider purchasing one.

You may get types that function similarly to smoke alarms and will alert you if there is a problem.

It should burn with the same strength and duration of flame outdoors in the open air as it does within the bunker, but in a more controlled environment. If the flame is feeble and low within, you may be experiencing oxygen difficulties; address them immediately!

Install Lighting

It is entirely up to you how you want to add lights, but I recommend painting the walls white or a very mild pale blue. This will ensure that the maximum amount of light is reflected and that your energy usage is reduced. Additionally, large mirrors can be used, which reflect light and seem darker in low-light conditions than white walls. Keep in mind that there is no such thing as day or night inside a bunker. The only source of illumination is artificial. It will be necessary for you to preserve your circadian rhythm.

Underground Bunker from Septic Tanks Summary

There is still a lot to be said about bunkers, but you should have a good grasp of the fundamentals by now. Remember that the rules of physics are always in effect, therefore try to approach this from a first-principles point of view while thinking about it. Heat, density, and pressure will all have an impact on how much airflow occurs. Heat is just the presence of energy in the surrounding air. Either you want to keep it in or you want to get it out. Make use of physics to your advantage and minimize your energy usage to a bare minimum.

Otherwise, I recommend that you get on those websites and start requesting prices for pre-fabricated bunkers.

I mean septic tanks as soon as possible!

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.

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.

Percolation Test

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

When you have passed a percolation test and obtained a building permit, your septic tank is ready to be professionally constructed.

It depends on the size of your home, the type of system you choose, and the material of your septic tank that you want to install. A list of the numerous treatment methods and tanks that are now available, as well as the normal pricing associated with each, is provided below.

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

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.

What size of septic tank do I need?

Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.

septic tanks for new home construction

The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.

For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.

planning your drainfield

Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.

  • Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.

a home addition may mean a new septic tank

Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.

  • For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

common septic questions

Here are some of the most frequently asked questions by our septic customers.

How do I determine the size of my septic tank?

If you have a rectangular tank, multiply the inner height by the length to get the overall height of the tank. In order to find out how many gallons your septic tank contains, divide the number by.1337.1337

How many bedrooms does a 500-gallon septic tank support?

The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size.

How deep in the ground is a septic tank?

Your septic system is normally buried between four inches and four feet underground, depending on the climate.

How to Locate Your Septic Tank

It may seem impossible to imagine that one of the largest and most visible elements of your whole plumbing system is also one of the most difficult to locate, but when your property is served by a septic system, this is perfectly true. A strong explanation for this is because septic tanks are huge, unattractive, stink horrible and give off an unwarranted impression of dirt. Not only does burying them underground assist to prevent them from harm, but it also provides you with additional useable space on your property and conceals what would otherwise be a blight on your landscape.

This site is dedicated to assisting you in locating your septic system without the need for any time-consuming digging.

How To Find A Septic Tank: Step By Step

It is critical to maintain the health of your septic tank since it is responsible for securely storing and handling the wastewater that drains from your house. It is necessary to pump your septic tank once every 1-3 years, depending on the number of people living in your household and the size of your tank, in order to avoid septic tank repairs or early failure, which means you must be familiar with the location of your tank. It’s not often simple to identify your septic tank, and many plumbers charge extra for this service, which is especially true if your tank’s lid is buried beneath.

1. Gather Some Helpful Tools

Septic tank location may be made much easier with the use of several simple instruments and techniques. To locate your septic tank, you only need to know the following information: A soil probe is one of the most useful instruments for locating a septic tank. It is a tiny piece of metal that is used to puncture through the earth and detect anything that could be buried underneath. Start at the point where your sewage line exits your home and work your way straight out, inserting your soil probe every two feet along the way.

Using this method, you may also locate the cover for your septic tank.

While we highly advise keeping your cover clean and exposed in the event that you require emergency septic service, we recognize that this is not always the case.

2. Use a Septic Tank Map

If you are a new homeowner who is trying to figure out where your septic tank is, a septic tank map should be included in your inspection documentation. You can use this information to assist you in pinpointing the exact position of your storage tank. If you don’t have access to this map, there are a few of additional strategies you might employ.

3. Start Ruling Areas Out

The location of a septic tank cannot be constructed in specific areas due to the risk of causing major damage to your property or tank, as specified by local rules. Your septic tank will not be affected by the following:

  • Immediately adjacent to your well
  • Beneath your home
  • Directly against your home
  • For example, underneath your driveway
  • Under trees
  • And other locations. Structures like a patio or deck are good examples of this.

4. Inspect Your Property

If you take a hard look around your land, there’s a high possibility you’ll be able to locate your septic tank without having to do any probing whatsoever. In many circumstances, a septic tank may be identified by a slight dip or slope on your land that cannot be explained by any other means. Due to the fact that the hole that your contractors excavated for your septic tank may not have been exactly the proper size, they proceeded to install the tank anyhow. This is a rather regular occurrence.

When there is a minor divot or depression, it indicates that the hole was too large and that your contractors simply did not fill the depression to level the hole.

The likelihood of your septic tank being discovered in a few specific locations is quite high.

  • Your water well, if you have one (for a variety of reasons that are rather clear)
  • Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built and no one performed a proper inspection before it was built)
  • Any paved surfaces (it won’t be under a driveway, sidewalk, or patio unless they were added after the home was built and no one conducted a proper inspection before it was built)
  • Any paved surfaces (it won’t be under a patio, sidewalk, or driveway unless they were added after the home was built If there is any particular landscaping

5. Inspect Your Yard

A comprehensive investigation of your yard may be necessary to discover your septic tank considerably more quickly in some cases. The following are important items to check for in your yard:

  • If your septic tank is overfilled, sewage can leak out into the ground and function as fertilizer for your lawn, resulting in lush green grass. A area of grass that is very lush and green is a good sign that your septic tank is just beneath it
  • Puddles that don’t make sense: If your septic tank is seriously overfilled, it is possible that water will pool on your grass. Another telltale indicator that your septic tank is below ground level is an unexplainable pool of water. Ground that is uneven: When installing septic tanks, it is possible that the contractors will mistakenly create high or low patches on your grass. If you come across any uneven terrain, it’s possible that your septic tank is right there.

The metal soil probe can let you find out for certain whether or not your septic tank is located in a certain area of your yard or not. As soon as your metal soil probe makes contact with the tank, you may use your shovel to dig out the grass surrounding it and discover the septic tank lid.

6. Follow Your Sewer Main/Sewer Pipes

Following your sewage lines is one of the most straightforward methods of locating your septic tank. These pipes have a diameter of roughly 4 inches and are commonly found in the basement or crawlspace of your house. They are not dangerous. Following the pipes from your house out into your yard, using your metal soil probe every 2 feet or so until you reach the tank, is a simple process once they are located. Aside from that, every drain in your home is connected to your sewage main, which in turn is connected to your septic tank.

The likelihood that one of your major sewer lines is located in your basement or crawlspace is high if you have exposed plumbing lines in your basement or crawlspace.

If the line is labeled, it is usually made of plastic or rubber. It is important to determine where this line exits your property and in which direction it is moving, as it often travels straight out to the septic tank itself.

7. Check Your Property Records

Lastly, if all else fails, a search of your property’s public records will almost certainly reveal the location of the tank you’re looking for. Your builders most likely secured a permit for your property because septic systems are required to be installed by law in every state. In order to do so, they had to develop a thorough plan that depicted your property as well as the exact location where they intended to construct the tank. This is done to ensure that the local health department is aware of the tank and is prepared to deal with any issues that may arise as a result of its presence.

If you look hard enough, you may be able to locate the original building records for your home without ever having to get in your car or visit your local records center.

What to Do Once You Find Your Septic Tank

Upon discovering the position of your septic tank, you should mark its location on a map of your property. Use something to indicate the location of your lid, such as an attractive garden item that can’t be changed, to help you locate it. A birdbath, a rock, or a potted plant are just a few of the possibilities. You are now ready to arrange your septic tank inspection and pumping service. Contact us now!
