How To Build A Septic Tank Out Of Concrete Blocks? (Best solution)

  • Can you build a septic tank with concrete blocks? After laying up the block and installing the inlets and outlets, you will need to plaster the inside of the tank with mortar mixed with a waterproofing additive and fill the cells of the block with grout. When you are done with this, and the grout is cured, you will form a lid for the tank.

Can you make a septic tank out of cement blocks?

Most states now have regulations prohibiting the use of site-built septic tanks using concrete blocks. Whether it’s to be cesspool or septic tank, the top should be a couple of feet below grade in northern climates so that bacterial action isn’t slowed by low soil temperatures.

How thick are the walls of a concrete septic tank?

The Construction The exterior walls of the septic tank are made of concrete, normally 4 inches thick. The concrete is either a minimum of 4,000 or 5,000 PSI concrete. A 1,200-gallon tank can weight as much as 8,000 pounds, so these are not items a homeowner can install on his own.

How do concrete septic tanks work?

The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Compartments and a T-shaped outlet prevent the sludge and scum from leaving the tank and traveling into the drainfield area. The liquid wastewater (effluent) then exits the tank into the drainfield.

What material are septic tanks made of?

Tank Materials Concrete, fiberglass, and plastic are commonly used. Concrete is sturdy, and it’s still used for some septic tanks today.

What should be the depth of septic tank?

Septic tank shall have minimum width of 750 mm, minimum depth of one metre below water level and a minimum liquid capacity of 1 000 litres.

What is a good size septic tank?

The recommendation for home use is a 1000 gallon septic tank as a starting point. The 1000 gallon size tank is a minimum and *can be suitable for a 2 bedroom, 3 bedroom house. Some recommendations say to add an extra 250 gallons of septic tank capacity for each bedroom over 3 bedrooms.

Are concrete septic tanks reinforced with rebar?

3 reinforcing rod (rebar). (11) The concrete tank and tank lid shall be reinforced by using a minimum reinforcing of six-inch by six-inch No. (13) A minimum 28-day concrete compressive strength of 3,500 pounds per square inch shall be used in the construction of the septic tank, concrete access riser and riser cover.

How do I determine the size of my septic tank?

Septic Tank Size Calculation based Per User Consumption

  1. Cooking – 5 Liters.
  2. Bathing & Toilet – 85 Liters/Person, So for 5 person – 425 liters/Day.
  3. Washing cloths & Utensils – 30 Liters.
  4. Cleaning House – 10 Liters.
  5. Other – 5 Litres.

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.

What is the cheapest septic tank?

Types of Septic Tank Systems These conventional septic systems are usually the most affordable, with an average cost of around $3,000.

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.

Rural Building Q&A, Septic System Install

Q. We have just purchased 15 acres, and our question is how to install our septic system, how far away from the on-site stream and can we use cinder blocks?A.The short, common-sense answer is that, with any sort of normal soils, a properly-functioning system with cinder (actually, these days, they’re concrete) blocks or even zero-cost fieldstone could be installed as close to the stream as, say 100 feet.The longer answer is that common sense may not be enough. That’s because most states have very detailed requirements for septic system installation, ranging all the way from professional-engineers-only design to minimum septic tank size and offsets from streams and property lines, including everything from fairly elaborate soil tests to bureaucratic on-site installation inspection.It happens that Vermont law still includes our so-called “10-acre exemption,” which allows any landowner with at least that lot size to design and install any arrangement he/she wants, as long as no effluent can be observed crossing the property line. This exemption has been under severe pressure by anti-rural-development advocates in recent years and won’t survive much longer, but while it does it allows a rural homesteader substantial design freedom at mimimal installation cost. There may be similar acreage-based exemptions in other states.Most states now have regulations prohibiting the use of site-built septic tanks using concrete blocks. They require instead factory-manufactured pre-cast concrete units, with minimum size ranging from 500 to 1000 gallons in which primary (anaerobic) bacterial treatment occurs. The effluent then flows by gravity to the typical perforated-plastic-pipe field, where runs of pipe are set into gravel trenches for secondary (aerobic) bacterial treatment to take place. From the holes in the pipe, the treated effluent then flows harmlessly through the gravel into the ground. Could you build a tank out of block, laid up in waterproof manner with mortar joints and surface parging, setting it on a fairly solid concrete slab so it won’t settle and allow cracks to open up? Sure, if the authorities will let you.The authorities might even let you build a tank out of dry-laid block, no mortar, with the core holes set horizontally, allowing the effluent to seep immediately into the ground. Such construction used to be made out of fieldstone and was called a cesspool; the design basis was that both anaerobic and aerobic digestion could take place in the same container, and the final effluent would be just as clean as in the more modern two-step system. If you go this route, you’ll most likely want to emulate the old-timers and build two or three cesspools, directing the sewage flow into one for a few years, while the others are allowed to “rest” and the sludge build-up in the surrounding soil to biodegrade.Whether it’s to be cesspool or septic tank, the top should be a couple of feet below grade in northern climates so that bacterial action isn’t slowed by low soil temperatures. There should also be a removable lid so that the indigestible sludge which builds up at the bottom of the tank and the organic mat at the top don’t fill up too much of the tank volume. Pumping every five years is usually recommended. If your design calls for the septic tank flow to go to a tile field, remember that the field pipes should be less than a foot from ground surface, so that the aerobic bacteria can get oxygen. You’ll need either a sloping site or an electric pump to meet this design essential.If you don’t fancy digging every five years to get to the tank lid, install an access route which is exposed at the soil surface. My own tank set up is properly buried, but over the lid opening there’s a three-foot length of three-foot diameter concrete pipe, with the lid on top of that. To pump the tank we just step through the surrounding flowerbed, lift the lid, and drop the pump hose down the hole into the tank. Slick.

How to Build a Concrete Septic Tank

Home-Diy If your home is not adjacent to a public sewer system, you may be required to install a septic tank and a lateral drainage system in order to treat your household waste properly. Pre-cast concrete septic tanks are easily accessible, but the cost of transport and installation is prohibitively high.

  • Survey of land grade
  • Permit
  • Excavation equipment
  • Steel reinforcing bars and ties
  • Sand
  • Concrete
  • Steel hooks
  • Manhole with cover
  • Crane


Although you may walk on top of the septic tank and drive a riding mower over it, you should avoid driving a car or tractor over it. If you are not familiar with the process of pouring concrete, you should hire a concrete contractor.


Form and pour as soon as feasible once excavation is completed. The soil might shift, causing a trench or pit to collapse. Maintain a safe distance between excavation and construction sites and keep children and animals out of the area. Septic tank construction is an involved operation that should be left to the specialists. As long as the local construction rules allow it, you may install your own septic tank on your property.

  1. Establish where your septic tank is located, as well as its depth. The fall of the sewage pipe that travels from the home to the intake outlet on the septic tank will be determined by your local construction codes. In addition, make sure that the water discharge line from the septic tank to the lateral leech fields has the proper drop needed by code. When determining the site, a survey crew will examine the gradient of your land. Excavate the hole into which you will pour the concrete for the concrete tank. A backhoe will be used to remove the soil from the pit and to build trenches for the pipe that will be used to connect the septic tank to the main sewer line. Fill the pit’s bottom with a minimum of 6 inches of sand or gravel to prevent it from sinking. In order to limit the likelihood of shifting or breaking, it is necessary to stabilize the base beneath the septic tank. First, form and pour the tank’s floor, installing steel reinforcing to ensure that the tank meets or exceeds local building regulations. Install the vertical steel rebar that will be used to brace the tank walls while the floor is being poured. Incorporating metal rebar into a wet concrete floor will provide a strong structural link between the walls and the floor. Install horizontal rebar rods and attach them using rebar ties to keep the structure stable. Despite the fact that the building code is mandatory here, normal rebar spacing is between 12 and 16 inches
  2. After the tank framework has been checked by the building inspector, order concrete. The building of septic tanks is highly regulated in most towns since a leaking tank has the potential to damage streams and water tables. Additionally, before you pour the walls, create allowances for the intake pipe and the drainage pipe. Separately, on a flat sand bed, form the tank cap to fit the tank. The cap’s measurements should correspond to those of the septic tank, and you will place a manhole in the form before pouring the concrete. You’ll also need steel reinforcement and four massive steel hooks that are positioned at each corner of the cap and extend all the way through the concrete to complete the project. The cap should be lifted from the sand bed with a crane by latching it onto the four steel hooks and carefully positioned atop the tank before covering the cap with earth

Unless there is documentable pollution happening from it then no need to update. Really the biggest risk is structural failure as the cinder blocks are really not made to be continuously wet. See Gene’s post below on wet cinder blocks. Additionally, killing the roots can also kill the helpful bateria that is “treating” the sewage in your system. A better approach (from the septic system perspective) is to kill the trees. Cut them down and keep them dead. Obviously do not allow tenants to park or drive over the area.

replace homemade septic(by BillS)Posted on:Oct 15, 2012 2:06 PMMessage:Ken just for clarity. The septic system is “designed” to “treat” the water prior to discharge to the ground. The “treatment” occurs when the sewage is detained in the tank and the anaerobic (without oxygen-septic) bacteria consume the nutrients and breakdown viruses, bacteria, other organisums and chemicals. Once the sewer moves through the tank it goes to the leach field where it is also “treated” by the orgnisums living in soil and rock around the field piping. The tank also serves to catch solids and prevents them from clogging the leach field. Tanks need to be pumped to prevent the solids frombuilding up and clogging the leach field causing premature failure. That is the theory and the expected life of a spetic system is about 20 years if properly constructed and cared for.

The photo at the top of the page shows a homemade septic tank that was being excavated after it was discovered that sewage effluent was being discharged into the drainfield. Septic system design, installation, inspection, maintenance, and repair procedures are covered in this series of articles. Topics covered include: defects in onsite waste disposal systems, septic tank and septic drainfield problems, and checklists of system components. questions to ponder According to my observations, site-built systems are frequently undersized and, worse, dangerous.

  • Apparently, the septic tank shown in this photograph was “home made,” with concrete blocks stacked to form the tank sides (and possibly the bottom) and a poured-concrete lid, which has been tipped over and can be seen leaning against the wall on the left side of this photograph.
  • In this specific situation the home manufactured septic tank was discovered to be totally filled with solids, and the leach field was found to be filled with solid waste as well.
  • While building your own septic tank is not an impossible operation, the size of the tank, and construction of materials to make sure that the tank and its cover are safe from collapse, are key concerns.

3 Tips to Maintain Your Concrete Septic Tank – Septic Maxx

Septic tanks are available in a variety of shapes and sizes and are constructed of a variety of materials, including cement, steel, and plastic, each of which has its own set of pros and disadvantages. Tanks made of concrete:

  • Possess high effluent concentrations
  • Possess a low likelihood of rising to the surface Are authorized in every state (as opposed to plastic tanks), and are environmentally friendly.

The fact that a majority of Americans choose concrete septic tanks over tanks made of any other material is a testament to these advantages. However, despite all of these advantages, if you have a concrete tank, you should be aware that it is possible for your tank to break under harsh weather conditions. This might result in costly leaks, which would make maintaining a concrete septic tank very difficult. These straightforward suggestions may assist you in maintaining your concrete septic tank and preventing cracks.

Reuse of Concrete Tanks

A long time has passed since concrete septic tanks were employed because of their durability. Despite the fact that they are prone to cracking, many people choose to reuse existing tanks in order to decrease maintenance and installation expenses. Before reusing a concrete tank, it must first be properly evaluated to verify that it is structurally sound and free of defects. Following the examination, the concrete tank must be refitted with a liner that is attached to the interior of the vessel.

It can also help to prevent corrosion, which is a leading cause of septic system failures, which can be quite expensive.

Repair Minor Damages

You should take care of any little damage to your concrete tank as soon as possible. As a result, you may extend the life of your septic tank and avoid minor problems from becoming major problems. The following are examples of typical concrete septic tank damages:

  • Pipe inlets and outlets that have been worn out
  • Baffles that have been damaged

Regular Inspections

The maintenance of a healthy septic system is essential. Pumping and inspecting your septic tank on a regular basis are required to keep it in good condition. Pumping is the process of removing sludge from a tank, whereas inspections are the process of checking the overall operation of the system. Identifying problems early on can save you from having to pay for incredibly expensive repairs later on. The proper maintenance of your septic system might assist to extend the life of your septic tank.

Septic Maxx provides environmentally friendly septic tank solutions that may do this, as well as minimize unpleasant odors and prevent material build-up in the tank. When you place your purchase now, you will have a very efficient septic tank treatment in your hands.

Some Useful Septic System Information For Homeowners

Sewage treatment systems such as septic systems are relatively recent, having been created to replace the older cesspool form of sewage treatment. Cesspools were common in the years preceding 1973. Such systems were mostly employed in residential and commercial structures where there was no municipal sewer system. These systems were mostly comprised of a drain pipe that was utilized as a conduit and was installed from the home to a cesspool. In other words, it is precisely the same as a regular sewage system, with the exception that it does not terminate at a public sewer.

Cesspools were becoming less popular in 1973, with many people opting for the more ecologically friendly septic system.

Natural filtering processes were performed at this location throughout their whole.

The physical integrity of a cesspool

The tank, often known as a cesspool, is constructed of cement block, concrete, or brick building materials. They are susceptible to collapse when the mortar wears away or the building itself deteriorates over time. Most of the time, the water in the tank itself exerts outward pressure, which helps to keep the tank’s walls from shifting. A tank that is empty can collapse far more readily than a tank that is filled. In any case, a collapsed septic system will necessitate the replacement of the system quickly.

Adding a leach field to an existing cesspool is not encouraged, and in certain regions, it is even prohibited.

There are a few critical considerations to keep in mind:

  • It is required that septic system tanks be built at a minimum distance from any structure (such as your home). That distance is typically at least 15 feet
  • Soil conditions must be thoroughly examined for permeability. The rate at which various soil types absorb water varies dramatically.

It may be necessary to change or reposition the current plumbing line that runs from the house, depending on the location of the permitted area. It is possible that a construction permit will be required for this project. It goes without saying that only licensed professional plumbers should be hired to complete the work. It is possible that your system is no longer working if you must pump it on a regular basis.

A Cesspool as a waste disposal system

A cesspool is a single chamber that gathers sewage as well as other forms of wastes. It is natural for the heaviest amount of wastewater (or the dirtier component) to collect at the pit’s lowest point. Sludge is the term used to describe the bottom portion of the mixture. Scum is formed when lighter items, such as soap and oil, float on the surface of the water. The amount of wastewater that is (relatively) cleanest is found in the space between the two levels.

Bacteria break down the bottom and top layers of the wastewater in the pit, and the remaining liquid is released into the environment where it will undergo more filtration before being recycled. Eventually, liquids seep into the ground from all three layers of the earth’s crust.

A Septic System

A septic system, on the other hand, is designed to keep the heaviest or dirtiest component of the wastewater at the bottom of a pit or tank. The system is made up of one or more plastic or concrete tanks that are connected together. Each tank has a capacity of between 1000 and 2000 gallons of wastewater capacity. One tank is directly linked to the building’s drain pipe, while the other is attached to a leach field. Only the partially treated wastewater is discharged into a collection area known as a leach field.

Another essential piece of septic system knowledge is the fact that the waste water is far cleaner than that produced by a cesspool.

How many homes use a septic system?

Septic systems are used by approximately one-quarter of all households in the United States. Rural locations or places that have not yet been served by a municipal sewer system are examples of where this may apply. Because some properties are located far from a connection point, connecting to a municipal sewer system can be a significant cost burden. Rather than using a more sophisticated wastewater treatment plant, these properties rely on the natural water filtering process to clean their wastewater.

  • On any given day, more than four billion gallons of inadequately treated effluent are discharged into the environment.
  • A septic system is a system that is privately owned and maintained by residents.
  • Another interesting piece of local septic system knowledge is that fewer than 10% of Long Island houses are still equipped with a septic system today.
  • A functioning septic system is quite unusual in New York City proper.

Septic system information regarding maintenance

A normal septic system should be emptied and cleaned by a professional once every two years (or sooner if necessary). However, keep in mind that this is merely a general recommendation. More information may be found at: Septic Tank Maintenance. When determining how frequently you should undertake complete maintenance, you must take into account the following factors:

  • The number of persons living in the home
  • The size of the septic tank
  • The quantity of wastewater that is generated
  • Volume of solids at the bottom of the tank that has been estimated

The Village of Great Neck Plaza is well-protected by the Balkan Drain Team (courtesy of google maps)

A Little Bit About Village of Great Neck Plaza

Great Neck Plaza is a community located within the boundaries of the Town of North Hempstead. This area is referred to as the North Shore of Long Island, and it is located within the boundaries of Nassau County. The Village of Great Neck Plaza has a population of somewhat more than 7,000 people, and it was founded in 1930 after being incorporated. When the railroad was extended to the village in 1866, it was a watershed moment in the development of the community. Because of this occurrence, the town went from being a rural village to becoming a commuting town.

The fact that Great Neck Plaza is such a tiny geographical area belies its energy and range of economic activity.

More than 260 businesses and establishments, as well as two parks, may be found within the confines of this small region of about 1/3 square mile. The community serves as a hub for the Long Island Railroad, and Middle Neck Road serves as its primary commercial thoroughfare.

10 DIY Septic System Plans You Can Build Easily

The installation of a septic system by specialists will cost you several thousand dollars. Why not take use of your spare time or weekend to construct a usable facility on your own time? That’s right; we’re talking about a DIY septic system that’s both basic and extremely functional, all at the same time. Understand the most effective ideas to adopt without exceeding the entire budget.

1. Three-Barrel Assembly

The simple video presentation allows you to set up a cost-effective system in a short amount of time. You’ll need a few empty barrels to collect the garbage that will be generated by the connecting pipelines. Unfortunately, the portrayal is somewhat brief; it simply provides a cursory description of the facility in a few basic lines. It is vital to cut the apertures with great precision in order to keep the assembly in precise alignment. The structuring procedure, on the other hand, is quite straightforward for anyone who is familiar with the fundamentals of plumbing.

2. Off-Grid Septic Cabin

Make a professional-looking installation of your essential septic tank, which you practically completed by yourself. A basic understanding of the fundamental needs of any setup on open ground is provided by this tutorial. The majority of the do-it-yourself effort consists of digging trenches to a certain depth and backfilling them. After you’ve finished excavating, you’ll need to build one drum/barrel using pipes that you found. Simple fittings will connect the empty barrel buried beneath the earth to the PVC pipe that will serve as the intake.

3. Concrete Septic Tank

Support your composting toilet with the most advanced septic system available, constructed entirely of concrete. Using the instructions in this article, you may convert an old composting toilet into a functional subterranean tank. All that is required is the excavation of a pit into which the prefabricated concrete block will be dropped using a crane. Digging trenches at various angles will ensure that the entrance and outflow are entirely separated. Filling the trench bottom with gravel once the perforated pipes have been installed will accomplish the desired result.

However, you may use internet tools to help you make decisions about your tank requirements.

4. Septic System Installation

It’s a long film that covers practically everything that happens on-site during the ongoing procedure. The envisaged system should be able to accommodate garbage from small to moderately sized dwellings, depending on their size. You will be responsible for digging trenches to connect the base pipe to the main bathroom line. And the pipe is routed directly into a holding barrel, which is secured firmly with a rubberized band around the edge of it.

Despite the fact that it looks to be a professional DIY plumbing work, the entire process is straightforward. It will take more time to complete the secondary criteria than it will to dig a bigger trench on the opposite side.

5. Retreat Property Septic System

It is possible to create a simple septic system on your property by using some well-conditioned garbage cans. The assembly is made possible by keeping the can vertical and in an upright posture. After digging the desired dirt, you must connect three-inch PVC pipes to the existing infrastructure. Rather than showing the construction process, the film begins with a description of the technology. Anyone who wants to grasp certain points in a speech must pay attention to the current debate. Although it appears to be simple to idealize a design, you do not have to ignore the reality when it comes to accuracy.

6. Off-Grid Septic System

Make your own small-scale off-grid septic system for the house out of materials you already have. When you consider that you will be working with brand new materials, the initial cost may appear to be a little exorbitant. The essential tools, equipment, and materials are discussed in further detail in the next section of the introduction. The onscreen live commentary should keep you interested for the whole 19-minute duration of this presentation. Its whole procedure, including the obvious facts, is documented in order to make the video longer.

7. Aerated Sewage System

A functioning wastewater system helps you manage your sewagenature while you’re doing it. A facility consisting of five interconnecting containers should be able to accommodate a large number of users. The first two containers continue to be anaerobic, but the third and fourth containers are completely aerobic. You’ll also need to chlorinate the fifth container to ensure that all bacteria are eliminated. One important point to note is that the containers must be installed on a flat surface. Simple explanatory comments should be plenty to keep you informed for the duration of the demo.

8. Complete Septic System Setup

The information in this post is particularly designed to help you set up your septic system like a professional. Everything, from the original cost to the final ground filling, will be made available to you upon request. Everything from site inspection to septic tank sizing based on usage to trench dimensioning is covered in detail in this instructional video. Not to add that the layout is ideal for a multi-story housing complex with an open backyard. The completion of its layout drawing should signal the start of the initial stages.

A solid concrete building appears to be the most suitable solution for meeting the requirements properly.

9. Multi-Lined Septic System

With a single sewage system, you can perfectly service a large number of one-story residential arrangements. The video instruction demonstrates how to construct a unique institution with a large number of drainage pipes. Of course, the setup will take a significant amount of time due to the fact that a vast pit with multiple trenches would need to be dug. Easy changes, on the other hand, are able to keep the task simple enough for people with limited hand strength.

You must either install a single massive tank or construct one for yourself out of concrete or a durable polymer covering. The rest of its implementation is straightforward, allowing you to simply connect the pipes.

10. Step by Step Septic Tank

Despite the fact that it looks to be a professional work, you can afford to have a few extra hands on deck for the project. To add insult to injury, it is the best septic tank to utilize for any normal multistory building. Even if the time-lapse video portrayal is likely to go at a quicker rate, it will nonetheless complete the work in question. Unless the facility is extremely large, the cost of setting up such a facility is prohibitively high. The goal of this project cannot be achieved only by the project manager within a reasonable time frame.


A do-it-yourself septic tank is a cost-effective solution for any DIY enthusiast who is interested in saving money. All that is required is that you match the requirements with the available solutions. You’re all ready to start gathering the items you’ll need for the project right there.

Concrete Septic Tanks Are Probably The Best Option — Build With a Bang

Concrete Septic Tank with a Capacity of 1000 Gallon When it comes to septic systems, whether you’re in the market for a new system or just need a replacement tank, you’ve arrived to the perfect location. As part of our recent investigation into different types of septic systems that are available for your house, we decided that it would be a good idea to also investigate the many types of septic tanks now available on the market. The following are the three most common types of septic tanks that are easily accessible for installation: When constructed properly and maintained on a regular basis, the majority of concrete septic tanks may endure for up to 40 years.

  1. Waste flow, home size, square footage, number of bedrooms, number of bathrooms, and a few other factors are taken into consideration in septic tank size recommendations and charts.
  2. Septic tanks are available in a variety of sizes, and you can even obtain tanks that are smaller than 1000 gallons; however, we recommend that you go with a tank that is at least 1000 square feet in size.
  3. Consult with a licensed expert before purchasing or installing any equipment if you’re going to install a new septic tank or septic system for the first time.
  4. ” A few of states are now requiring 1000 gallon tanks as the minimum size requirement.

The popularity of the concrete septic tank can be attributed to its strength, weight, and longevity. For more precise information on durability, concrete septic tanks that are correctly constructed have a lesser probability of breaking, cracking, or floating.

Check out these 6 septic systems available for your home.

Nowadays, most concrete septic tanks are sold with a two compartment design, as opposed to the earlier style one compartment tank that was more common previously. Two compartment tanks tend to perform a better job of filtering and separating waste than one compartment tanks, which is why septic experts advocate them over a single compartment tank. All compartments are constructed with access for cleaning and pumping, regardless of the number of compartments in the system. Because it can readily handle most 0-3 bedroom dwellings, a 1000 gallon septic tank is the standard size for domestic applications.

Heavy Duty Options

Many tanks are also available in “high duty” configurations, which generally have a reinforced top and bottom. Purchasing the heavy-duty version may be a wise decision in the case that a vehicle, agricultural equipment, or other large piece of heavy machinery passes over the tank area.

Installation Requirements

Because of the size and weight of concrete septic tanks, they must be installed by a qualified specialist. These tanks are constructed of the hardest materials available, and while they are extremely durable, their installation necessitates the use of enormous, heavy machinery. If the intended or present site of your concrete septic tank does not allow for heavy machinery access, you may want to investigate a fiberglass or plastic (polyethylene) tank. Due to the fact that the majority of concrete tanks are precast, their sizes, weights, and dimensions are all different.

Lifespan and Durability

The method by which the concrete septic tank was constructed will have an impact on its long-term function. High-quality concrete, adequate water sealing, and the use of structural steel goods such as mesh and rebar will provide additional support, strength, and structural integrity to the structure. Keep in mind that concrete septic tanks are more prone to cracking and leaking than their plastic and fiberglass equivalents when exposed to exceptionally cold temperatures and pressures. Most concrete septic tanks have a lifespan of up to 40 years if they are constructed properly and serviced on a regular basis.

1000 Gallon Concrete Septic Tank

Septic tanks of 1000 gallon capacity or larger are the most typical size for household usage, as they can readily fit most 0-3 bedroom dwellings. Size Weight: The weight of each concrete tank is different. Some of the most common 1000 gallon concrete precast tanks are around 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Others are approximately 5′ 1″ X 8′ 2″ X 5′ 8″ in size and weigh almost 9,000 lbs. Here are some examples of Jensen Precast projects completed in various cities around the United States.

1250 Gallon Concrete Septic Tank

Generally speaking, a 1250 gallon tank is a good choice for mid-size homes with 3-4 bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. 1250 gallon concrete precast tanks are typically 5′ 9″ x 8′ 6″ x 5’8″ in size, with some of the more common models being 5′ 9″ x 8′ 6″ and others measuring 5′ 8″. The typical weight of a 1250 gallon concrete tank is 11,000 lbs, however this might vary depending on the distributor. Approximately 11 1/2 feet in depth, however this varies according on the distributor, state, and local statutes.

In addition, many of these bigger tank sizes are so massive that rebar and wire mesh are required within the walls and between layers to provide additional strength, stability, and durability.

1500 Gallon Concrete Septic Tank

Generally speaking, a 1500-gallon tank is the most popular size for large homes with five or more bedrooms. Size and weight: The sizes and weights of all concrete tanks are different. The dimensions of some of the most common 1500 gallon concrete precast tanks are around 6′ x 10′ 9″ x 5′ 5″ in length and width. The typical weight of a 1500 gallon concrete tank is 12,000 lbs, which is rather heavy. Approximately 12 feet in depth, however this varies according on the distributor, state, and local statutes.

Inlet Baffles

When installing a septic tank, an inlet baffle should be put on the inlet part closest to the point at which the sewer tank joins from the house structure to the tank. Due to the fact that it prevents scum and oils from blocking the entrance pipe, the inlet baffle is critical to the overall health and effectiveness of the septic system. The intake baffle is a bottle neck that is especially designed to do the following:

  • In order to prevent the breakdown process from being disrupted, it is necessary to slow the effluent entering the septic tank. A fast rate of inflow of effluent might cause problems by mistakenly combining the settled solid waste with oils, scum, and effluent. Make sure no sewage gases are allowed to enter the sewer line. These gases have the potential to infiltrate back into a home or structure, generating a foul odor.

Outlet Baffles

Every septic tank should be equipped with an exit baffle that is connected to the discharge line. The outlet baffle functions as a bottle neck in the same way as the inlet baffle, but in the opposite direction. It is meant to:

  • Preserving the septic tank by keeping scum, oils, and solid waste contained inside
  • It is necessary to prevent the discharge of waste items other than wastewater into the output pipe, drain field, and leach field.

All effluent from the septic tank must be clear of solid waste before it may be discharged. Other than that, the solids and oils will pollute the drain field/leach field and result in backups and pollutants entering the surrounding environment. Ensure that your baffles are correctly built and that they are not in need of repair by consulting with a licensed septic technician before doing anything else. Septic tanks made of fiberglass or polyethylene (polyethelyene) are also a suitable option, especially if your location has specialized environmental requirements.


In contrast to concrete septic tanks, which normally need a vehicle equipped with a crane and boom, fiberglass and polyethylene septic tanks are quite simple to transport. Therefore, fiberglass and plastic tanks are frequently employed in places where concrete septic tank delivery vehicles are unable to reach the tanks. The majority of fiberglass and plastic septic tanks weigh roughly 300 pounds or more, however concrete septic tanks can weigh up to 20-30 times as much.

Cost Effectiveness

If you’re seeking for a less expensive alternative to concrete, fiberglass and polyethylene (polyethylene) are excellent choices. The majority of fiberglass and plastic septic tanks are thousands of dollars less expensive than concrete septic systems.


When compared to a concrete septic tank, both plastic and fiberglass septic tanks have a lower likelihood of breaking. Furthermore, because fiberglass and plastic are nonporous materials, there is typically no problem with tree or bush roots growing into the tank and generating leaks as a result of root damage. Having said that, due to the tank’s smaller profile and lighter material composition, caution must be used during installation because heavy gear might easily harm it. Tanks made of fiberglass or plastic can be destroyed in the same way as concrete tanks can if too much weight is placed on the surface above them.

Despite the fact that plastic and fiberglass tanks are quite resilient, they can nonetheless leak under specific circumstances.

As a result, it’s important to contact with a septic installation specialist before making a final decision on a certain material. The size of the lot, the position of the tank, the amount of ground water, and the weather can all influence the selection.


Plastic and fiberglass have a number of advantages, but they can also be troublesome. Yes, the lightweight character of these materials makes them perfect for installation, but same lightweight nature also results in a high level of buoyancy in the final product. It is possible that during a storm, a plastic or fiberglass tank can get dislodged from its couplings, causing considerable damage to the septic system and the homeowner’s property, with repair costs in the hundreds of dollars. A simple solution is to place a concrete slab on top of the tank to help weigh it down.

If you reside in an area with a high groundwater table, consult with a specialist to ensure that the higher water table will not cause harm to your fiberglass or plastic tank.

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. It is possible for septic tank installation mistakes to result in system failure, which can result in not only costly repairs, but also a very unpleasant scenario to deal with. 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. These ditches should be dead leveled in order for the water to run out onto the ground beneath each trench.

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.
