How many lids should a concrete septic tank have?

Two or three lids may be included in your system. The average size of a sewage tank is approximately 5 feet by 8 feet. The lid is buried between 4 inches and 4 feet underground in most cases.

How heavy is a septic tank lid?

The most common tanks, starting in the 1940s, are concrete, with 3 – 500# lids for a 1000 gallon tank or 4 – 500# lids for a 1500 gallon tank. In the late 1990s, tanks started using 16” square concrete plugs with a lifting bail for easier access to both sides of the tank.

What can I use for a septic tank lid?

The Do’s For Hiding Your Septic Tank

  • Plant tall native grasses with fibrous roots around the opening to conceal the tank lid from view.
  • Place a light statue, bird bath or potted plant over the septic lid.
  • Septic tank risers and covers are an alternative to concrete and blend into green grass.

Should septic tank lid be sealed?

Like wells, septic systems have problems if they are not sealed from outside surface water. Most septic systems rely on buried pipes to get rid of the fluids. The lid covers should fit tightly — if they don’t, a company that specializes in septic repairs should be called to fix them.

How do you replace a septic tank lid?

Position a pry bar between the top of the septic tank and the lid. Ask your helper to hold the handle on top of the lid. Push down on the pry bar to lift up one end of the concrete septic tank lid. Ask your helper to pull the lid handle and slide the lid to the side.

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.

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). So, most residential tanks should have (2) lids about 5′ away from each other. A septic tank holds all the liquid waste from your home (toilets, sinks, kitchen, bathtubs, floor drains).

How Can I Make a Concrete Septic Cover?

Home-Diy 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 need to empty or examine it for leaks. You may construct a concrete septic cover, which provides more protection and discourages animals from attempting to enter the system. if (sources.length) then this.parentNode.removeChild(sources); then this.onerror = null; this.src = fallback; )(,; )(,; )(,; (//$/, “), ‘/public/images/logo-fallback.png’) (//$/, “), ‘/public/images/logo-fallback.png’) ” loading=”lazy”> ” loading=”lazy”> Septic tank covers made of concrete are a reliable method of keeping them secure.

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. Fortunately, the bar can be simply removed, allowing for access to the septic tank underneath.

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 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.

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 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.

  1. 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.
  2. The high duty riser and lid systems placed at ground level are sturdy enough to withstand being mowed directly over.
  3. As a result, there is no need to spend the additional time and energy trimming around them.
  4. Aeration Septic Inc offers a choice ofseptic tank covers and lidsfor sale.

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 to Replace a Concrete Septic Lid With a Plastic Lid

Photograph by Jupiterimages/ ImagesMost concrete septic tanks are constructed with hefty concrete lids over the manholes and access holes, which are subsequently filled with dirt to complete the 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.

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. Also put on safety gear, including 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. Generally, the tank is between 1 and 3 feet below the surface of the earth and up to25 feet from the home. 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 lids 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, making sure to seal 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.

Concrete septic tank lid conversion?

I even considered lifting one lid and forming a form around it, then pouring a new one into the form with a pipe nipple already in place. I’m a little concerned about the usage of what you refer to as a “pipe nipple.” That conjures up pictures of a hose fitting tightly or possibly something to which the hose may be attached. I believe it is advisable to provide lots of additional space around the hose. The “honey dipper” always used the extra space available in the suction hose (pump out is a 14″ square hole) to stick a pole into the tank to agitate it and use the hose to spray inside, keeping everything moving so that there was little if any residue left in the tank every time we had our tank pumped (1000 gal with a 250 gallon riser).

Personally, I’d check with the people who do the pump out; they’ll most likely be able to help you, or they’ll be able to recommend someone who can install a gasket and collar with lid for you.

Just my two cents.

Despite the fact that the lid of your septic tank appears inconsequential, it is actually one of the most crucial components of the system. An improperly sealed tank will allow odors to seep out while also allowing foreign objects to enter the tank, which can cause clogging of the system. As a result, it is critical that you change this lid on a frequent basis.

Step 1 – Find the Septic Tank

In order to remove and replace the lid of the septic tank, search for and locate it. This can often be more difficult than it appears, particularly if you have a large property to manage. To begin, choose the simplest route possible by contacting local tank pumpers, previous homeowners, or the health agency in your neighborhood. They may be able to provide you with information on the location of your septic tank, which can save you a great deal of time and effort searching for it. It may be necessary to locate the sewage outflow from your home if the simple method does not work.

Examine the grass in a square 10 to 20 feet outside of where the pipe exits, where it appears to be greener and healthier than the surrounding area.

If the septic tank lid is above ground level, as is frequently the case, there is no need for excavation. Remove any longer grass or trash from the section of greener grass where the lid is located by simply walking over to it.

Septic Tank Risers, Lids, and Covers

The following are some of the most commonly asked inquiries that our customer support representatives are asked. Take a peek below; it’s possible that the queries you have have been answered! Would the POLYLOK SEPTIC TANK LID fit directly on the ADAPTER RING, or will I need to use a RISER to ensure a proper fit on the tank? With the exception of the 24″ Heavy Duty Lid, the lid will often fit straight onto the adapter rings in the majority of cases. The underside of the 24″ Heavy Duty Lid is strengthened for added strength.

  • Therefore, the 24″ Heavy Duty Lid will only be able to be used without using an adapter when the opening is at least 24″ in diameter.
  • ALL other Polylok lids will attach straight to the adapter ring, eliminating the need for a riser or any other adaptor.
  • No.
  • Cutting the riser will result in the lid not being adequately secured on the riser that has been cut down.
  • It is entirely up to you whether you want to bring the riser system up to grade, raise it above grade, or leave it slightly below grade.
  • If the riser system is located in a high traffic location or is going to be run over by lawn equipment on a frequent basis, the heavy duty lid is recommended.
  • Yes.

IS IT INCLUDED WITH THE POLYLOK SEPTIC TANK RISERS AND LIDS TO USE SCREWS? Yes. The Polylok Septic Tank Risers are assembled using stainless steel screws that allow them to be connected to one another. If you have any more queries, please contact us at 1-877-925-5132 or [email protected]


Riser systems are available in a variety of shapes, sizes, and designs on the market today. The Polylok septic tank risers are, without a doubt, the best money can buy in this category. There are several causes for this, but the following are the most significant:


The Polylok brand is the only one on the market that is sent to you from the factory with gaskets already in place, making it unique. This means that there is no further work necessary to ensure that the riser system is air and water tight! Keep ground water out of your tank, wastewater in your tank, and potentially hazardous gases out of your yard! In contrast to most other products, our Polylok septic tank risers do not require you to purchase or use any other type of sealant between each riser part.


The Polylok risers are reinforced with structural ribs that run internally around each riser segment, providing them with exceptional strength and allowing them to maintain their shape even after the hole is backfilled with dirt. As a result of the freezing and thawing of the ground in many parts of the country, it is necessary to have a smooth surface on the outside of the riser’s exterior. It is possible for items that have structural support on the outside of the riser to actually be lifted from the tank, causing damage to both the riser and seal, during periods of freezing and thawing.


The septic tank access lid on a riser system is one of the most significant components since it is the part of the system that is visible from the outside and that must be removed every time the system is pumped or otherwise serviced. The Polylok lids are pre-installed with handles, which make it simple to remove the lid whenever you need to get access to the system or to replace it. The bottom of the lids is structurally supported, which allows them to remain relatively flat rather than domed in shape, as is the case with many other items on the market.


It is necessary to use an adapter ring in order to attach risers to your septic tank. We have one of the largest adapter rings available on the market, allowing you to cover up to a 25″ square or 27″ circular aperture with a Polylok adapter ring. This ring fits both 20″ and 24″ risers, allowing you to have a great deal of versatility no matter what size your opening happens to be!


At Septic Solutions, we strive to make the buying and installation process as simple as possible for our customers. All of our Polylok risers and lids are delivered with all of the stainless steel screws required for installation in one package.

Septic Tank lid construction and fabrication

Septic tanks made of precast concrete are the obvious choice. When it comes to selecting a septic tank for your property, there are several alternatives to consider. First and foremost, you want to be sure that the tank you choose has the appropriate capacity for your home. After that, you’ll want to be certain that you select a tank that will give years of dependable service for you and your family members. A precast concrete septic tank is the most suitable option.

Precast septic tanks provide several advantages over other types of tanks, such as plastic, steel, or fiberglass. Because of this, concrete septic tanks are required in a large number of cities and municipalities. The Advantages of Using a Precast Septic Tank

  • The tanks weigh a great deal. While this may be considered a disadvantage by some, we feel it is one of the most significant advantages of using carbon fiber over other materials. Because of the weight of the precast concrete septic tank, it will never “float” to the surface, which is something that certain lesser weight tanks may accomplish in certain scenarios. Precast concrete septic tanks have a specific gravity of 2.40, which makes them more resistant to buoyant forces than other septic tank materials. HDPE has a specific gravity of 0.97, which is very high. For anchoring structures composed of more buoyant materials, further labor-intensive and time-consuming on-site preparation is required. When selecting a septic tank for your property, it is important to consider the following factors: Precast septic tanks do not rust, which is a major concern. Steel tanks, as well as portions of some plastic and fiberglass tanks, are extremely susceptible to corrosion and failure. Unlike traditional concrete, precast concrete gradually gains strength over time. Other materials, such as steel or high-density polyethylene (HDPE), can degrade and lose their strength. The contents of precast concrete storage tanks may be pumped out without the risk of the tank collapsing. The process of installation is basic and uncomplicated. Shea Concrete offers a staff of tank installers that have completed hundreds of tank installations in the past. We are well-versed in site preparation and are capable of overcoming virtually any installation challenge. In addition, we have vehicles that are fitted with hoists and can even crane a tank over a house when necessary
  • Concrete, along with water, is the most widely utilized building material on the planet. This natural substance is non-toxic, ecologically safe, and comprised entirely of natural materials, making it an excellent choice for septic tanks. Concrete is employed in a variety of applications throughout the country and has no negative impact on the quality of groundwater or surface water. During the installation process, plastic tanks are susceptible to damage. It is possible to trace the majority of failures of plastic tanks back to the installation process
  • Plastic tanks should never be driven over by a vehicle. This may set restrictions on the location of the tank and leaching area on your land.

Why A Concrete Septic Tank?

Because of their size and weight, the tanks are extremely difficult to transport. While this may be viewed as a disadvantage by some, we feel it is one of the most significant advantages of using composite materials over other materials. A precast concrete septic tank will never “float” to the surface, as certain lighter-weight tanks can do in certain scenarios; instead, it will remain submerged. Precast concrete septic tanks, with a specific gravity of 2.40, outperform other septic tank materials when it comes to buoyant forces.

  1. When anchoring structures made of more buoyant materials, additional labor-intensive and time-consuming on-site preparation is required.
  2. It is fairly common for steel tanks and components of some plastic and fiberglass tanks to corrode and fail.
  3. The strength and durability of other components, such as steel or HDPE, might decrease.
  4. Hundreds of tanks have been installed by the Shea Concrete team of installers.
  5. Whenever necessary, we can crane a tank over a home using one of our vehicles equipped with hoists.
  6. Septic tanks may be created out of this material since it is non-toxic, ecologically safe, and manufactured from natural elements.
  7. During installation, plastic tanks are susceptible to damage.
  8. Plastic tanks should never be driven over by a car.
  • Strength increases with time
  • Durability
  • Ease of installation
  • Low susceptibility to damage during the backfill process

Installing Access Risers

In order to perform fundamental septic system maintenance, you must first evaluate the condition of your septic tank and pump chamber (if you have one), which can be time-consuming and labor-intensive if you do not have access ports known as risers. Consider the prospect of having to dig through two feet of dirt to check the oil on your vehicle. Installing septic tank risers for an off-site septic system is broken down into four steps, which are outlined below.

Please keep in mind that the currentWashington State Coderequiresrisers for all septic systems, which means you may be forced to install one if you are asking for a construction permit, land division, or any other type of official action in the state.

A few safety tips before you get started:

  • Struck by an underground electrical wire while excavating may be quite dangerous! If you are in any way doubtful about the presence of subterranean lines on your property, you can have them found by contacting 1-800-424-5555 or 811, or by visiting the website
  • Use the buddy system to your advantage! Working with a partner is usually recommended since the fumes connected with open sewage can be dangerous and cause a person to go unconscious. Never leave a septic tank that is open unattended! Once the lids have been removed, exercise caution around the tank and keep dogs and children at a safe distance. Examine the structural integrity of your septic tank! If a septic tank is more than 20 years old, it is recommended that it be pumped to ensure that the tank’s structural integrity and water-tightness are not compromised. Instead of spending money on costly repairs, it is preferable to replace the tank with a contemporary septic tank that includes risers as part of the installation. A permit from your local Environmental Health department is required for the replacement of a septic tank.

Gather all the MaterialsTools You will Need

There are many various varieties of PVC risers available. Some of the brand names you may be familiar with are “Tuf-Tite,” “Polylok,” and “Orenco.” Most of the components required to install septic tank risers should be readily available at your local plumbing hardware shop or on the internet. Risers are typically 24 inches in diameter and can be readily fitted over the tank hole opening. However, some tanks have square apertures, making it difficult to put a round riser over a square opening in some cases.

Some types of risers are made to order based on the height you want, while others are available in increments of 6-12 inches.

Then purchase an Adapter and Risers that are somewhat bigger in diameter than the hole.

The following steps will guide you through the process of attaching risers to the tank entrance.

  1. Tank Adapter Ring (TAR)
  2. Riser Adapter Ring Kit
  3. Butyl Rope
  4. Risers
  5. Domed Lid OR Flat Lid
  6. Stainless Steel Screws

The following materials will be required for digging up your septic tank(s):

  1. Drawing of the septic system in its “as-built” condition
  2. A measuring tape of some sort
  3. Shovel
  4. Tool for probing
  5. Protection for the eyes
  6. Gloves for the job

To cut risers to the proper size, the following tools are required:

  1. Circular saws, saber/jig saws, and hand saws
  2. Raspor file
  3. Marking pen
  4. Tape measure
  5. Drill with a 1/4″ bit

Materials required to seal the risers to the tank include:

  1. High-strength concrete patch mix
  2. A small bucket
  3. A mixing stick
  4. And gloves

Follow the four simple steps outlined below to install access risers on your septic components, or download and print a copy of theSeptic Tank Manhole and Access Riser Installationbrochure from Thurston County Environmental Health to get started right away.

Step 1: LocateYour Septic Tank(s)

When looking for your underground septic tank or tanks, it is essential to consult the ‘As-built’ Record Drawing linked with your septic system for assistance. Essentially, this is a plot diagram that shows where your septic system was put on your property, as well as distances between septic components and notable landmarks. The Online Permit System will guide you through the process of locating septic-related documentation if you do not have a “as-built” document. It is possible that you may need to contact Environmental Health to examine the paper records or seek a specialist to find your tank if an as-built is not accessible.

Probing the area around the septic tank with the probing instrument until you contact concrete should be done lightly.

WARNING:Underground electricity orother utility lines or cables might be close or above your septic tank, and ifyou touch a power wire it could be dangerous!

Step 2: Uncover Your Septic Tank (s)

Once you’ve discovered your septic tank, you may start digging about. The tank is typically 6 feet wide by 8 feet long, with the width being the largest size. Remove all of the pebbles and debris from around the tank’s lid openings and dig out the whole top of the tank. You will want to clean out any dirt that has accumulated on the surface of your septic tank. This will assist you in ensuring that you generate a high-quality seal. You should have two openings: one over the inlet (which comes from the home) and another over the outlet (which comes from the yard) (into the drainfield or pump chamber).

  1. You’ll need a riser for each of the doors you open.
  2. Typically, the inlet side is the one that is nearest to the home.
  3. When cleaning the tank, it is beneficial to remove the complete top of the tank.
  4. Risers must be modified in order to be correctly installed, and all manholes (holes 24 inches or bigger in diameter or square in shape) must also be updated, as well as the tankinlet and outlet baffle covers (if separate from the manholes).
  5. If you discover one – and only one – riser already installed, it is most likely for the pump chamber, which only requires a single riser to provide access to the pump to function properly.
  6. Remove the concrete lids, after the project is completethey may be removed, you will not need the concrete lids once risers areinstalled.
  7. USE CAUTION: NEVER leave an open tank unsupervised!
  8. You should make sure that dogs and children are not allowed near the tank when it is open; you don’t want them to accidentally fall into the tank.
  9. It is preferable to complete the task with the assistance of another person.

You should be aware that exposure to sewage can result in serious sickness, so make sure you wear gloves and thoroughly wash your hands afterward with soap and water. It is also recommended that you wear eye protection in the event that debris falls into a tank and splashes back at you.

Step 3: Fit Risers to Component Openings

In accordance with the diameter of the septic tank manholes, huge risers will either sit on top of the septic tank or will fit down into the aperture of the tank by 1-3 inches. It’s important to keep this in mind while calculating the height of the riser. The surplus can be easily removed; nevertheless, it is difficult to add a few inches to the length. Take the following measurements of the manhole cover’s diameter:

  • Theriser will fit into the tank hole if the aperture is between 26 and 29 inches in diameter. Measure the distance from the ground to the top of the septic tank and multiply the measurement by three inches. The following is required if the aperture is greater than 29 inches: a 3-foot square fiberglass plate (with a 22-inch hole in the middle) is required. In this case, it lies above the manhole and narrows the aperture, allowing a 24-inch riser to be utilized instead of a more expensive 30-inch riser, saving money.

The distance between the ground and the top of the fiberglass plate should be measured. You may choose to place the risers so that they are level with the surface of the ground, or you may want them to stand out a few inches above the ground (if a riser is above ground make sure you are careful when mowing). Tips: To shorten a large riser with ribs, drill a 1/4-inch hole between the ribs above the cut line and finish the cut by following one of the grooves between the ribs with a saber/jig saw to finish the cut.

By eliminating one of the ribs from the largeriser, it may be made to fit more snugly into a smaller manhole entrance.

Step 4: Attach Risers toSeptic Tank (s)

It is recommended to pump out an old septic tank that is 20 years or older in order to check its structural integrity and water-tightness before using it again. If the tank requires extensive repairs, it is preferable to replace it with a new septic tank that includes risers as part of the installation. A permit from the local health department is required for the replacement of a septic tank. Clean out the top of the tank, removingall dirt and debris. Using the butyl rope, construct the components of the risers in accordance with the manufacturer’s instructions.

  1. Jet-Set, Rapid-Set, Thorough-Set, and Perco-Plug are just a few of the brand names available.
  2. NOTE: For optimal results, just a little amount of concrete patch should be mixed at a time.
  3. The patch mix should be used to seal the riser to the septic tank.
  4. If you want to avoid a safety danger, make sure you properly attach theriser lid using the screws that come with it!
  5. Risers for inlet or outlet apertures that are smaller than the openings should have the bottom few inches sanded with rough sandpaper to allow a firmer connection between the two surfaces.
  6. A useful source of information on correct installation of risers on septic tanks may be found at your local hardware store where you purchased the risers and covers.

Thurston County Environmental Health is should be commended for providing the foundation for this documentation.

  • Deck Repair for Septic Tanks – Sulfuric acid may eat away at the concrete deck that sits on top of a holding tank over time. It is extremely dangerous for the tank to collapse if the concrete’s sand and rock are no longer keeping it together properly. If the tank’s floor and side walls are still in good condition, we may be able to cast a new deck on top of it and do some bridge work to rescue the tank from being destroyed.
