  • Every septic tank has at least one cover, which helps release gas but allows access to the tank for septic companies who must drain or inspect it for leaks.
  • Then pour thick, heavy-duty cement into the frame and smooth it out.

What size is a septic tank lid?

Locate The Lid Most septic tanks are rectangular and measure about 5 feet by 8 feet. Probe around the tank to locate its edges and mark the perimeter of the rectangle. A septic tank installed before 1975 will have a single 24-inch concrete lid in the center of the rectangle.

How much does a septic tank lid weigh?

The concrete covers also weigh 60 – 80 lbs. Because of the weight, many people are discouraged from removing the cover and doing an inspection. Modern plastic septic tank riser rings typically weigh less than 30 pounds.

Why does my septic tank have 2 lids?

Solid, watertight, buried tank made of concrete, plastic, fiberglass or metal. This tank has a way in (inlet), and a way out (outlet).

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.

Are septic tanks reinforced?

Precast septic tanks are typically manufactured in two pieces, either with a seam at the lid or midseam. Steel reinforcement is used according to the tank design to provide additional structural capacity during handling, installation, testing and use. Usually precast septic tanks are manufactured in two pieces.

How Can I Make a Concrete Septic Cover?

As a result of its ability to supply filtered water to depleted aquifers, Jim vonMeier believes that septic systems are the solution to America’s water deficit. As an advocate for septic systems around the country, he speaks at conferences, gives lectures, and appears in court. For septic system inquiries, as well as information on the operation of the septic tank, contact him through email or letter.

Measure and Pour

Measure the top of the septic tank cover area, and then use that measurement to construct a frame around which to pour the concrete. The frame should be constructed of aluminum or any other malleable metal that can be pulled away from drying or cured concrete without damaging the structure. Increase the width of the concrete cover frame by an inch or two on each side so that it overhang the top of the entrance and completely covers it. Then, pour a thick layer of heavy-duty cement into the frame and smooth it out with a rubber mallet.

After you are pouring, make sure there are gaps around the border of the frame so that when it dries, you can easily remove the cover from the frame without damaging the frame.

Allow at least one day for the concrete to cure before attempting to remove it.

Handles and Installation

As soon as the concrete has been poured and is beginning to dry, add metal handles to the wet cement so that you may raise and move the cover with more ease. In an ideal world, these metal handles would be created from bent steel beams similar to those used in construction, but they may be made from just about any sort of metal that will enable concrete to harden around it firmly. Lift and transport the cover to the septic tank, making sure it fits over the entrance, when the concrete has set and the handles are in place.

Security of Cement Cover

It is unlikely that someone will attempt to remove the massive concrete cover that you have erected for your septic system in the majority of circumstances. Even so, placing a metal bar over the top of the concrete and locking it in place may be a smart idea for covers used in more sensitive situations, such as commercial buildings or public places of worship. When a metal bar is attached to a piece of metal or chain that has been screwed into the concrete or metal around the top of the septic system, it may be secured in place.

The Drip Cap

  • At the absolute least, every septic tank has a cover, which not only aids in the release of gas but also gives access to the tank for septic firms that must empty or examine it for leaks. Afterwards, pour a generous amount of heavy-duty cement into the frame and smooth it out
  • Using the handles, raise and carry the cover to the septic tank to ensure that it fits over the entrance
  • Once the concrete has cured, remove it from the tank and discard it.

How to Build a Concrete Septic Tank

In every septic tank, there’s at least one lid that assists with gas leakage while also allowing for access to the tank for septic firms when they need to drain or examine it for leaks. Afterwards, fill the frame with thick, heavy-duty cement and smooth it out; Using the handles, raise and carry the cover to the septic tank to ensure that it fits over the entrance; once the concrete has dried, remove it from the septic tank.

  • 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

How to Make a Septic Tank Cover

  • 2-foot length of 1-inch diameter plastic pipe
  • U-bend made of 1-inch diameter plastic pipe
  • A large plastic barrel
  • An electric or manual saw
  • And a hammer. Door knobs that are big and strong

It is not necessary to undertake a significant building project in order to replace a septic tank lid. Some septic tank covers, which are designed to lay on top of a tank to protect it from excess moisture – and to shield you from unpleasant odors – have been known to disintegrate and collapse into the tank itself. The worst-case situation is the replacement of the whole tank, which can cost thousands of dollars in labor and materials. It is possible to rebuild a concrete tank lid if the structural integrity of the septic tank has not been harmed by the collapsed cover.

See also:  What Does Septic Tank Gas Smell Like? (Solution)

Step 1

Cut a huge shape out of the bottom of the plastic barrel that is approximately 1 foot deep. In order to properly cover the whole septic tank entrance, the form should be larger than the tank opening plus a few inches to allow for overlap. Place the plastic pipe in the centre of the barrel, vertically up, in the center of the barrel. The pipe will serve as a tank vent when it is installed.

Step 2

According to the manufacturer’s directions, mix the cement well. Fill the barrel to a depth of 4 to 6 inches with the liquid.

Step 3

Place the handles on top of the cement and secure with screws. To ensure that the handles reach at least 3 inches into the cement, they should be at least 3 inches long. Allow at least 24 hours for the cement to dry. After that, you should be able to lift the septic tank cover by the handles.

Step 4

Remove the barrel from the concrete with a saw. Make sure that the cover fits tightly over the top of the septic tank when it is placed over the tank. The U-bend should be attached to the top of the straight pipe that emerges through the cover. The U-bend will allow rainwater to escape from the tank without accumulating any of it.


Select a plastic barrel that is large enough to cover the opening of the septic tank drain. It is possible that you will need to cut the tank in the middle and use a piece of plywood for the bottom half of the form.


Do not let the septic tank lid fall to the ground. It will be rather heavy, and if it is dropped, it may shatter – or cause other objects to break.

How to Replace a Concrete Septic Lid With a Plastic Lid

Jupiterimages/ Images is the source of this image. In most cases, thick concrete lids over manholes and access holes are used to build concrete septic tanks, which are subsequently covered with soil after installation. While this is a satisfactory installation, many septic specialists recommend that the concrete lids be replaced with plastic risers and lids to provide for easier access to the tank for examining and cleaning the system.

The new plastic top is now easily accessible for pumping and maintenance thanks to the addition of a riser. The plastic lids are also bolted down, which adds an additional layer of protection for the homeowner and his or her family.

How to Replace a Concrete Septic Lid With a Plastic Lid

Remove any furniture, potted plants, yard décor, and other things from the surrounding area. Protect your pets, and keep other people and children away from the area. Put on your protective gear as well, such as gloves and safety goggles. When working with concrete, always use a dust mask or a respirator to protect your lungs from the silicates in the dry mix that can cause irritation.

Step 2: Locate the Tank and Lids

Identify the tank and its covers. As a result of the shallower soil and reduced ability to hold moisture for the lawn’s roots, dead grass may be an indication of the tank’s position. A metal detector may be used to discover rebar in concrete tanks, after which it can be probed to locate the edges.

Step 3: Remove the Soil

Remove all of the dirt that has accumulated on top of the septic tank. In most cases, the tank is located between 1 and 3 feet below the surface of the earth and up to 25 feet away from the home, depending on the conditions. When it comes to dimensions, the typical septic tank is around 4 1/2 feet broad and 8 feet long; however, larger tanks are available. Check for structural damage to the tank as well; cracks or a drooping top signal that repairs or replacement of the tank are necessary.

Step 4: Measure the Lid

Take the diameter of the lids, as well as any tank inlet or baffle outlet covers, and round them up. If the bigger lid, sometimes known as a “manhole” lid, has a diameter greater than 24 inches, it may be necessary to use an adapter before placing the lid riser over the hole. Adapters are available from the company that makes the lid riser.

Step 5: Remove the Lid

Remove the concrete covers from the containers and set them aside. Because the concrete lids are so heavy, it may be necessary to utilize a backhoe to complete this task. It is best not to breathe any of the fumes that are rising from the septic tank and to use a protective mask or respirator to minimize exposure.

Step 6: Adjust the Riser Height

Obtain an accurate measurement of the distance between the tank and the ground. Make any required adjustments to the riser in accordance with the manufacturer’s instructions, or in older systems, consider installing a riser to raise the new lid to ground level. The present riser’s height can be reduced by drilling an appropriately sized hole in it and then trimming the surplus riser length using a jigsaw, as shown in the image below. Some manufacturers create adjustable risers, which eliminates the need for cutting.

Step 7: Rough the Riser Base

Using 40- to 60-grit sandpaper, sand the area around the base of the risers. Place the risers over the manholes, as well as the intake and outflow holes, after wiping them down with a tack cloth.

Step 8: Apply Concrete Patch Mix

In a bucket, combine the quick-drying, high-strength, flexible concrete repair mix that has been advised. Work rapidly, since the mixture will dry in 15 to 20 minutes if left to sit. With a trowel, apply a generous amount of sealant around the bases of the risers, being sure to cover the edges all the way up to the top of the septic tank. Allow for a thorough drying time.

Step 9: Attach the New Lid

Set replacement lids on the risers, following the manufacturer’s instructions and using a socket wrench to secure them in place.

Step 10: Rebury the Tank

Soil should be used to cover the septic tank. Cover the bare soil with sod or grass seed to prevent it from becoming naked.


  • Inspect and pump the tank (if necessary) while the lids are off
  • This will save you time and money later on. After finishing the activity, thoroughly wash your hands and clothing with soap and hot water to remove any remaining dirt.


  • You should never enter or even put your head inside a septic tank unless absolutely necessary. Every year, a number of people die as a result of the fumes produced by septic tanks
  • You may pass out, fall in, and suffocate or drown. When the lids of the septic tank are open, never leave the tank alone, even for a single minute. It is possible for a kid or pet to fall in and drown
  • Avoid driving over the risers and lids.

How to Replace a Concrete Septic Lid

Septic systems employ a concrete cap to limit the infiltration of smells and sewage into the surrounding soil. Every five years, the lid must be removed in order for the septic system to be emptied out and the tank to be cleaned. When concrete septic tank covers become cracked or damaged in any way, they must be replaced immediately. Purchases of this nature can be made online or at a home improvement store in your area. Many septic tanks are equipped with risers, which allow the lid to be seen above ground.

Make arrangements with the utility companies to come out and mark the position of electricity and water lines before beginning work on a concrete septic lid replacement.

Dig Down to the Septic Lid

Spade or shovel the dirt around the concrete septic lid until you reach the septic tank lid, and then remove the septic tank lid. Septic tanks are typically located 12 to 14 inches below the surface of the earth. In order to have enough area to work when taking the septic tank top off the septic tank, it is preferable if you dig a perimeter around it that is 16 inches wide. It’s also a good idea to dig 2 inches past the seam where the lid and tank come together. If your lid is mounted on a riser, there is no need to poke around underneath.

Lift Off the Lid

A pry bar should be inserted between the top of the septic tank and the lid. Instruct your assistant to grip the handle on the top of the lid. One end of the concrete septic tank lid may be lifted up by pressing down on the pry bar. Instruct your assistant to pull the lid handle and slide the lid to the side while you work. You may need to repeat the method for the opposite end of a big rectangular lid if the lid is rectangular in shape. With the assistance of your companions, lift the septic tank lid away from the tank.

Check the seal on the top of the septic tank for damage.

Measure the Lid

Using a tape measure, measure the length and breadth of the aperture to your septic tank chamber. Purchase a replacement sewer cover from Home Depot or another supplier depending on the measurements you’ve taken thus far. The old lid should be placed back on top of the septic tank, or the tank entrance should be covered with a tarp if it will be several days until your new lid comes.

Clean the Seal

Using a putty knife, scrape away any remaining old seal from the top of the septic tank if necessary.

The majority of the seal will fall out in large chunks. With a wire brush, clean the top of the tank entrance to remove any remaining traces of the seal as well as any loose concrete.

Install the New Lid

One end of the new septic tank lid should be lifted while the other end is lifted by your assistant. Lower the concrete lid over the septic tank with care, ensuring that the seal between the tank and the lid is compressed. If you have to dig to get to the septic tank, you should cover it with the earth.

How septic tank lids and covers are saving you money – Aeration Septic

A septic tank system may be one of the most expensive mechanical elements on a property, making it one of the most important investments. It is also one of the least thought about or comprehended of all the concepts. It may be tempting to flush it down the toilet and forget about it, but doing so may be quite costly in the long run, since regular maintenance and monitoring can help to avoid pricey repair fees. Risers and lids for septic tanks are an excellent and cost-effective solution to ease future maintenance and monitoring of the tank.

What are septic tank risers and lids?

While your septic tank is located beneath the earth, septic tank risers provide a big diameter “well” that allows for a safe access point to the sewage tank to be located at ground level if necessary. The lid is attached to the top of the riser and is designed to completely encapsulate the system in an airtight and watertight manner.

In this way, surface water and debris such as grass clippings, mulch, and soil are prevented from entering the tank. It also helps to keep gases and smells from leaking from the septic system as well.

There are several benefits to septic tank risers and lids

First and foremost, having a clearly visible septic tank lid on the property serves as a pleasant reminder that a septic system is in place. However, whereas older-style concrete coverings were considered to be heavy and unattractive, current plastic lids are lightweight and made to integrate with the surrounding environment. These lightweight variants make it simple and cost effective to install, monitor, and service your septic system, and they are also easy to transport. Savings on expenses By establishing an access point at ground level, service experts will have an easier time locating the septic system for routine maintenance, repairs, or to pump out the septic tank as necessary.

  • Stainless steel threaded fasteners are used to connect lids to the riser and keep them in place to avoid tampering by minors and potential falls into the septic tank.
  • The high duty riser and lid systems placed at ground level are sturdy enough to withstand being mowed directly over.
  • As a result, there is no need to spend the additional time and energy trimming around them.
  • At Aeration Septic Inc, we provide several different types and sizes of septic tank covers and lids.

Septic Tank – adding riser to concrete lid
Author:kratman (GA)Question from homeowner on addingrisers to a concrete lid. I have a concrete tank (estimated at 1,500 gals, circa late 70’s) and the top is about 3 feet below ground level. The lid is composed of a series on concrete “planks” that are the width of the tank long and about 2.5 feet wide. So the planks sit laterally on top of the tank to form the lid. I am unsure how many planks are in total (since the entire lid was not exposed when it was recently pumped), but I would guess four planks total.Since the lid is so deep and pumping it made a real mess in my side yard from digging the area to expose the first plank, I wanted to add risers. The septic company wanted $1,500 to add two risers at both ends; but I wanted to explore some options. How does one add a riser to the plank units? Or would I go about getting this manufactured (precast company, etc)? I would guess the entire plank is replaced, but since they are only 2.5 wide, the riser diameter presents a problem. Thank in advance.

Re: Septic Tank – adding riser to concrete lid
Author:KCRoto (MO)Don’t take this wrong- I highly recommend having a riser installed to allow access to the tank.That being said, I don’t think that the average homeowner is up to the task of installing it.There are several factors in play.You need to have a riser that is larger than the current lid or has the same inside diameter as the opening you have currently.Then you need to consider the amount of weight that you are adding to the rim of the current opening.If you are adding too much weight, you could cause it to cave in.Also consider the weight of the riser itself when you would be installing it.Do you have the capability to set it properly?If you can handle the challenge, then I suggest contacting a local concrete vault or fabrication company; they can get you what you need as far as a riser and new tank lid.This forum isn’t for pricing, but I can tell you that in my opinion, adding risers, lids, and installation to two spots doesn’t seem unrealistic.

Author:KCRoto (MO)Unless you installed it, you are making it up as you go.Septic tanks aren’t made to specific dimensions anywhere.I have seen concrete in varying sizes, shapes, and thicknesses. I have found them made of clay, steel, and plastic.Every concrete vault manufacturer has its own design, lid size, and placement.

Re: Septic Tank – adding riser to concrete lid
Author:Wheelchair (IL)I can tell you what I did.It worked for us.Our septic tank was 1200 gallon and concrete. We had 3 slabs, each having 2 loops of re-bar for lifting them.Each slab was about 3 ft x 5 ft and were laid side by side.I did exactly what you want to do.I made a frame using 2 X4 and plywood under.I was able to obtain a 3 ft piece of 20 inch PVC pipe.I secured the pvc inside of the form and secure everything with rows of re-bar.I oiled all of the wood and used plastic bags as a liner to keep the concrete off the forms.My neighbor was pouring a slab of concrete in his drive was and he had some extra material.3 wheel barrels and I pour the concrete into my form. I added 2 hook loops and let the concrete dry for 3 days before I removed the forms. The slab with the 3 ft stack was lifted and place on the edge of the septic tank.We back filled with dirt and sand to compact the area to almost the top of the stack.I went to a specality shop that sold septic system supplies.Only then did I realize that the industry made 4 inch x 22 inch, stackable flange pieces that snapped together to form any height.I purchased a 22 inch dome cover and placed it over the 20 inch pvc pipe.It worked perfectly and allowed me to add an additional 3-4 inches of dirt over the cover. No one walks on the cover.Removing 3-4 of dirt is a lot easier to do and repair.I’m happy and that was over 3 years ago.That’s 3 snowy winters.Best Wishes

Author:hj (AZ)Maybe so where you are, but here, almost EVERY tank, regardless of who made it has an access port above the baffles. They also usually have a large center port, but no one installs a riser at that one.

Author:KCRoto (MO)Many of the older tanks here don’t even have baffles.

Thanks to all
Author:kratman (GA)ok Thanks. All good ideas. I had thought about pouring the lid myself, and may do that. But I will speak to a tank manufacturer in the area first.I have not checked the middle of the tank for an existing access hole but will do that as well. 3 feet of Georgia clay is not much fun. Thanks. Kratman.Edited 1 times.
