How do you measure a septic tank cover?
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 wide are septic tank lids?
During the search, keep an eye out for a circular lid approximately two feet wide. Septic tank lids are typically green or black plastic; sometimes they are made of concrete. It’s not always easy to find the lid, though, as unkempt grass, dirt, or debris can conceal the septic tank lid.
How far apart are the lids on a septic tank?
The distance between lids will be different for each sized tank: 1000 gallon tank = 6-6.5 ft.; 1250 gallon = 7-7.5 ft.; 1500 gallon = 8.5-9 ft.. Dig up the outlet chamber access lid. If you are extraordinarily lucky, the as-built drawing is accurate and you have hit the lids spot on.
How far down is septic tank lid?
Often, septic tank lids are at ground level. In most cases, they have buried anywhere from four inches to four feet underground.
How thick is a concrete septic tank lid?
The exterior walls of the septic tank are made of concrete, normally 4 inches thick.
What size are concrete septic tanks?
What sizes do concrete septic tanks come in? Standard tank sizes are 1000 gallon, 1250 gallon, and 1500 gallons nationwide.
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.
How many lids are on a 1000 gallon septic tank?
Single Compartment 500 – 1,000 Gallon Septic Tanks: Installed up to approximately 1976, this tank style will have one main lid and two smaller baffle lids on both ends of the tank as shown in the diagram below.
How to Find the Lid on a Septic System
All septic tanks eventually fill with sediments and must be pumped out on a regular basis in order to remain in excellent functioning order. If the tank’s lid is not on a riser at ground level and you are not the home’s original owner, you may be unable to determine where the lid is located. A typical septic tank is 4 inches to 4 feet underground, with all of its components, including the cover, buried between 4 inches and 4 feet underneath. This is true regardless of whether the septic tank is equipped with special risers that keep the lid flush with the surface of the ground.
Consult A Map
First, choose with the most straightforward choice. The installation of septic tanks at all locations is recorded in most counties’ permission records, which are kept on file for future reference. Typically, this will include a schematic indicating the placement of the tank on the land, as well as certain dimensions that will allow you to measure to the precise site of the tank. If your tank was placed before your county made it a requirement to record the location of such tanks, you may find yourself with nothing to show for your efforts.
Search For A Sign
Septic tanks are placed in such a way that they are as unnoticeable as possible on the land. After the grass has grown back after installation and some time has passed, it is possible that just a few visual indications will remain. Pay particular attention to the contours of your yard for any inexplicable high or low points that might suggest the presence of an underground storage tank.
Follow The Pipe
Installation of the septic tank takes place along the sewage line that runs from the house into the front yard. Locate the 4-inch sewage pipe at the point where it exits the home in the basement or crawl space, if it is there. Locate the same spot outside and make a note of it. Insert a thin metal probe into the earth, identify the 4-inch sewage line, and follow it across the yard, probing every 2 feet, until you reach the end of the property. Septic tanks are required to be at least 5 feet apart from the home in all states except Alaska.
Whenever the probe makes contact with flat concrete, fiberglass, or polyethylene it indicates that the tank has been located.
Locate The Lid
The majority of septic tanks are rectangular in shape and measure around 5 feet by 8 feet. Investigate the tank’s circumference to determine its boundaries and outline the rectangle’s boundary using a pencil. A septic tank that was built before 1975 will have a single concrete lid that is 24 inches in diameter in the center of the rectangle. If the tank was built after 1975, it will have two covers made of fiberglass or polyethylene, centered at the ends of the rectangle and centered at the ends of the rectangle.
It should be possible to uncover the lid or lids by digging with a spade in specific spots, depending on when year the tank was constructed.
Call A Professional
Opening a septic tank is a job best left to the pros once the lid has been discovered. Concrete septic tank lids are extremely heavy, and many require the use of lifting tools to remove them completely. An open tank has the potential to release toxic gases. Anyone going around on the property who comes into contact with an exposed septic tank might be in risk. Because of the noxious vapors present in an open tank, falling into one can be lethal.
Mark The Spot
Make a note on the ground near where the tank was pumped by a professional and the lid was buried to serve as a reference in the future. In order to keep track of where you are, you should choose a hefty circular patio tile that is embedded in the ground. Additionally, draw your own map of the area and store it with your other important papers.
Concrete Septic Tank Lid: Sizes, Weight & Cost (Explained)
An underground septic tank is used to store all of the foul-smelling soil that travels through the drain. A concrete septic tank not only removes the obstruction from the drain, but it also helps to maintain our environment clean. For the purpose of inspection and cleaning, a concrete-made septic tank lid is always required for the concrete septic tank to function properly. It also prevents the foul odor that emanates from the tank from reaching its surroundings outside of the tank. As a result, we have included a brief explanation of the sizes, weights, and prices of the concrete septic tank lid in this post.
How big and thick is a concrete septic tank lid?
Depending on the size of the tank, a concrete septic tank lid might be as large as 30 inches. The concrete tank lid can have a thickness of more than 3 inches, and the concrete thickness can range between 3000 and 6000 PSI, depending on the application. If the lid is composed of firm concrete with a high PSI, the thickness of the lid might be greater than 6 inches in some cases. The size of a septic tank lid is typically determined by the size of the actual septic tank. Because the typical dimension of a concrete septic tank is 40 inches by 60 inches, this is the most common configuration.
In addition, the size of the septic tank varies based on the size of the concrete tank used in the system.
Before discussing the thickness of a septic tank lid, it is important to remember that the thickness of the lid is directly proportional to the strength of the concrete.
A thicker lid can be used in this situation if the thickness is greater than 5 inches.
How much does a concrete septic tank lid weigh?
Most of the time, an unpainted concrete septic tank lid weighs between 10 and 12 pounds. The weight of the lid, on the other hand, is determined by the quality of the concrete as well as the strength of the concrete itself. If the primary sewage tank is 5 inches by 7 inches in dimension, a septic tank lid might weigh as much as 15 pounds. It is critical to accurately balance a septic tank lid in order to avoid damage to the tank. This is due to the fact that you will need to lift the septic tank’s cover in order to clean and check it.
Because the thickness of the lid will determine how much weight it will have, the greater the thickness of the lid will be.
If the PSI of the concrete is between 4000 and 6000, the weight of the lid might be greater than 15 pounds. Furthermore, if the weight of your septic tank lid is greater than 15 pounds, it will be quite difficult for you to lift it up for cleaning reasons, so plan on using a helper.
How much does a concrete septic tank lid cost?
Concrete sewage tank lids are typically priced based on the size of the primary septic tank. The cost of a lid that will precisely cover septic tanks ranging in size from 9000 to 13000 gallons (which is the largest) will be in the neighborhood of $500 or more. The typical size, which is 25 inches in length, will cost around 40 dollars to purchase. According to industry standards, the cost of a concrete septic tank lid is typically determined by the size of the concrete lid. The most expensive concrete septic tank lid is 130 inches in diameter and costs around 500 dollars.
How to build a concrete septic tank lid?
We’ve outlined the quickest and most straightforward procedure for constructing a septic tank cover. The following is a description of the procedure:
First and foremost, you will need to determine the size of the mouth or entrance region of your septic tank, which can be found here. Then, using a measuring tape, you must precisely determine the location of the septic tank’s perimeter.
Build a frame:
The following phase will be to construct a frame that will be based on the same measurement as the septic tank’s mouth. Aluminum or dry wood should be used to construct the frame. However, make certain that the frame is free of the cement once it has dried.
Pour the cement:
You have now finished pouring the cement into the frame. It is important to keep the lid thick enough to be durable and long-lasting, so make sure you keep it at least three inches thick. The surface of the cement must next be smoothed and flattened to complete the process. Check to see that you have used light-duty cement instead of heavy-duty cement.
How many lids should a concrete septic tank have?
Depending on the size of the septic tank, it may require at least two lids. This is because pouring concrete for your septic tank might be a difficult task. When you initially attempt to construct a lid for your concrete septic tank, you should be able to construct at least two lids. The reason for this is that, if you construct two covers for your septic tank, you will have an easier time during the cleaning and inspection processes. Additionally, if you include two lids to the septic tank, the ventilation system of the septic tank will run more smoothly.
How much does it cost to replace a septic tank lid?
The cost of constructing an average-sized septic tank lid will be around 60 dollars. A septic tank system with two lids will cost between 110 and 120 dollars, depending on how many are included. If you choose the heavy-duty free cement, the price will be somewhat greater than if you do not. Because strong duty-free cement provides a long-lasting and durable finish to the lid. Additionally, the cost of fabricating a custom-sized septic tank lid will be in the neighborhood of $100. To be more specific, it will cost more than 500 dollars to construct the largest possible lid, which is 130 inches in diameter.
How to lift and replace the concrete septic tank lid?
Lifting and replacing a concrete sewage tank lid is far more difficult than installing a new septic tank lid, as you may imagine.
As a result, we’ve covered the quickest and most straightforward method of removing and replacing the concrete septic tank lid:
Dig around the lid:
First and foremost, you must excavate around the septic tank. Because it will provide additional room for lifting the lid. In order to dig around the lid, you will need to dig around 15 inches deep. It is preferable if you dig up the area surrounding the septic tank lid that is 15 inches in diameter after the first 15 inches.
Lift up the septic tank lid:
You will need to raise the lid with the assistance of a stout bar or pry bar at this point. Insert the bar between the tank’s lid and the tank’s bottom. You will next need to ask your assistance to lower the opposite end of the bar until it is flush with the ground. Repeat the procedure until the lid of the tank is entirely removed from the entrance of the tank’s opening.
Install the new lid:
It is now necessary to determine the size of the septic tank’s opening. Then you must purchase the lid, making certain that the measurements are accurate. Install the new lid by gently holding it in place with the assistance of your assistant. Finally, place the cover on top of the septic tank and secure it in place.
Can you replace a concrete septic lid with plastic?
If your septic tank requires frequent examination and cleaning, you can opt to replace the concrete septic cover with a plastic one. Because most septic tanks need to be cleaned after 1 to 2 years, they are built with a thick cover to prevent this from happening. If you have a septic tank that has to be cleaned on a regular basis, it is preferable to use plastic covers. However, because plastic lids are easily lifted up, ensure sure the lock system on the plastic lid is functional.
Should septic tank lids be airtight? How to seal a concrete septic tank lid?
Yes, it is vital to seal the septic tank from the outside world. Because it is possible that exterior water will seep into the septic tank. Additionally, if your septic system is placed on top of the soil, it is essential that the septic tank be correctly installed. If this is not done, the tank will overflow due to the exterior water. Although many types of sealant ropes can be used to seal a concrete septic tank lid, the most common one is silicone. There are several different types of butyl sealants available on the market that may be used to firmly seal the septic tank lid.
Septic tank lids are available in a variety of sizes ranging from 25 to 50 inches in diameter. Furthermore, the thickness of a typical-sized lid can reach up to 3 inches. However, the cost of a standard-sized lid is 50 dollars, and it may occasionally be even more expensive than this. In addition, the weight of a 25-inch lid might be as much as 50 pounds in some cases.
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; )(, arguments.target.currentSrc.replace; )(, arguments.target.currentSrc.replace; )(, arguments.target.currentSrc.replace; (//$/, “), ‘/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.
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.

Septic Tank Covers
What is the depth of the Septic Tank Cover once the Septic Tank has been identified? Is the cover in good condition?
Septic Tank Cover Depthlocation
Tank Cover Depth: How deep will the septic tank cover be is a question that many people ask. Most of the time, the top of the septic tank is roughly one foot below the level of the ground. However, the depth of the water fluctuates greatly. The septic cover, on the other hand, can be several feet deeper. If you take note of the depth at which the waste line leaves the building foundation wall, for example, 3 ft. below the top of the soil (grade level), and if the site were dead flat and the tank were located 12 feet from the foundation wall, at a typical waste line slope of 1/8″ to 1/4″ per linear foot of run, the septic tank’s entry port for the waste line would have to be approximately 3 ft.
3″ below grade level. If the site were dead flat and the Obviously, if the site is not flat, these septic tank cover depth estimates would be different than before.
Septic Tank Cover Safety Procedures
Take extreme precautions to ensure that the coverings and cleanout access covers over the septic tank are secure and long-lasting, so that it will be difficult for someone to fall into the tank (which is sometimes deadly), and that children will not be able to remove the cover. If your septic tank is located in a location where vehicles may drive over it, heavy-duty rated covers are available for your convenience. This is something you should discuss with your septic tank contractor. Even if there is the slightest doubt about the condition of the septic tank cover (for example, if there is evidence of subsidence over the tank location), you should cordon off the area and prevent anyone from walking over it, because falling into a septic tank is extremely dangerous and could result in death.

Reader Question: septic tank cover collapse
11/28/2014 The following is what Scott C. said:I have a septic system that is powered by a pump tank. The weight of the dirt beneath which the lid was buried caused the lid to fall. There were around 3’2″ of them “because of the clay type dirt that the installer used to cover it The thickness of the lid is four millimeters “. Is that up to par for a soil with so much organic matter? –
Scott, The collection of data is necessary in order to determine whether or not the cover over a septic tank is adequate. Septic tanks are, in fact, designed to handle a variety of weights and loads. See SPECIFICATIONS FOR SEPTIC TANK DESIGN STRENGTH As previously stated, simply measuring the thickness of the septic tank lid is insufficient to determine whether or not it was adequate; we do not know if it contained steel reinforcement, if it did, at what spacing and with what material; nor do we know the quality of the concrete; nor do we know its history (for example, prior vehicle traffic over the tank); nor do we know the size of the septic tank.
Reader Question about septic tank cover security regulations in Alberta
04/30/2015 Septic Tank Lids made the following statement: Could you possibly provide me with information on the regulations governing septic tank lids in Alberta? We have a concrete BellSiphon, and I’ve noticed that the lower and smaller lids (one from each compartment) are being left at the top of the bigger lids, as well as beneath a cover on our concrete patio. Is this normal? When I confronted the owner of the pump truck firm, he responded by saying “Because they are a nuisance, that is an excellent location for them to be.
as well as the metal hooks snapping.
We’ve had the same tank system for 40 years and have always had it covered.
Thank you so much, Jane.
STL: Here is an excerpt from the Alberta septic tank code for your information. 22.214.171.124. Lid/Cover Opening with Easy Access 1) All access holes must be provided with a secure lid or cover to prevent unauthorized access. 1 One purpose of this regulation is to promote safety by prohibiting unauthorized or inadvertent entrance into the access aperture of a septic tank or holding tank. Sentence (1) explains how this regulation works. The use of a padlock and a cover that can only be removed with tools are examples of acceptable protective measures, as is the use of a cover that weighs a minimum of 29.5 kg (65 lb).
The following further comments on these techniques is provided in the handbook: It is critical that the lid or cover of the manhole access aperture be securely fastened in order to prevent someone from accidently falling into the tank below.
When the access lid is first installed, it must be secured; it is then the owner’s obligation to ensure that it stays secure on an ongoing basis.
In summary, if the lid over your septic tank can be lifted by a child, the chance of someone falling into the tank is high, as is the possibility of a swift and horrible death. Make certain that the coverings are secure.

Reader Question: how do I cap this wiring conduit at my septic tank cover?
2013/0318 NT inquired:Our dogs have pulled what looks to be a portion of our septic system that was obstructing electrical wires. What is the best location to look for a replacement? NT, a reader, sent this photograph.
Reply: proper conduit and exterior electrical boxes are required for outdoor septic pump wiring
NT: When I look at your photo (above), the white plastic “tube” appears to be a riser conduit for septic pump or alarm wire. I’m not sure if it’s a product specifically developed for that use or if it’s a homemade couduit produced from downspout material. I would start by contacting your septic installer or maintenance firm to find out what type of material they used. This may save you a lot of time digging around in your yard. In the meanwhile, make sure you cover the top of the conduit with a tarp or other temporary cover to keep rainfall out.
Keep an eye out: I have my doubts about whether or not the conduit utilized was appropriate and certified for electrical wiring.
The figure on the right illustrates what I am referring to: the use of specified components for subterranean and outdoor electrical wiring with a riser that is elevated above the ground.

Jonathan You will need to excavate just enough of the septic tank to be able to estimate the measurements of the tank cover, at the very least at the corners. Meanwhile, if the tank cover is destroyed, be sure to rope off the area and keep people away from the area since if someone falls into the tank, they would die quickly and horribly. I jumped over the concrete cover and fell to the ground. What is the best way to determine what size I require? Janet The replacement lid needs to be safe (falling into a tank is lethal), which means it needs to be robust and it needs to be secured to the tank’s top.
- Yes, it is technically conceivable.
- Do you have a pad for sale, or do you know where I may get a hold of one?
- One of the lid’s corners split and dropped into the tank, creating a hole in one of the corners.
- Perhaps there are sewer fly problems because the top of the tank is not properly sealed?
- The PVC vent cap to which you refer is suitable for use as a cleanout access cap, however it does not function as a ventilation cap.
A cap is something I’m seeking to put on – does it need to be vented or slotted?

Please notify me and upload a snapshot of what you have discovered so that we may discuss it further.
It is usual for a septic tank to have some floating particles, such as the following: excrement and toilet paper, as well as lumps of grease, are OK; however, bits of wood or roots are not.
Throughout my system, I have four green circular covers.
I’m confident that it is an aerobic system.
My home is just around 14 years old, and I have heard that having four covers indicates that it is a newer variety.
I’d want to know what’s going on in each tank, what appears to be normal, and what might cause me to be concerned about the status of my tank.
They came out and cleaned up what they could before telling me that they would pump it all out if there were roots uncovered.
Approximately four weeks later, it began to burp once more.
Tank one had a large clump of roots floating about, which I removed; tank two appeared to be in fine condition.
I took out those portions of text.
The burping has subsided once more.
When they drained it out, I was wondering why there were so many chunks floating about.
I’m having trouble finding anything on Google.
However, I suspect the time, trouble, and cost of doing so will be comparable to the cost of purchasing a new concrete cover from your local septic supplier.
In addition, I have another spherical concrete one that is located over the sewage pump tank.
I think what I’m asking (and what you probably won’t be able to truly provide me with) is a way to cover it now that the area has only been excavated down a foot or so, but rain and sand are going to seep into it.

How to Replace a Concrete Septic Lid With a Plastic Lid
Jupiterimages/Photos.com/Getty 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.
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.
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
It should be possible to get most of the components required to construct a septic tank riser at your local plumbing hardware store or on the internet. PVC risers are available in a variety of shapes and sizes. Some of the brand names you might be familiar with include “Tuf-Tite,” “Polylok,” and “Orenco.” Risers are typically 24 inches in diameter and may be readily inserted into the tank hole opening without difficulty. Due to the fact that certain tanks have square openings, it might be difficult to fit a riser around the square entrance.
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.
See below for Step 4 on attaching risers to the tank entrance. For the purpose of installing a riser system on your septic tank, you will require the following components:
- Tank Adapter Ring (TAR)
- Riser Adapter Ring Kit
- Butyl Rope
- Domed Lid OR Flat Lid
- Stainless Steel Screws
The following materials will be required for digging up your septic tank(s):
- As-built condition of the sewage treatment system The following items are required: sketch on paper, measuring tape, shovel, probing instrument, eye protection, and work gloves.
To cut risers to the proper size, the following tools are required:
- Circular saws, saber/jig saws, and hand saws
- Raspor file
- Marking pen
- Tape measure
- Drill with a 1/4″ bit
Materials required to seal the risers to the tank include:
- High-strength concrete patch mix
- A small bucket
- A mixing stick
- And gloves
Follow the four simple procedures shown 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 now.
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.
The presence of underground electricity or other utility lines and cables might put your septic tank in danger.
Call 1-800-424-5555 or 811 or go online to make sure that any electrical utilities are found before you begin digging before you begin digging.
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).
- You’ll need a riser for each of the doors you open.
- Typically, the inlet side is the one that is nearest to the home.
- When cleaning the tank, it is beneficial to remove the complete top of the tank.
- 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).
- 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.
- Remove the concrete lids so that they may be disposed when the project is completed.
- Consult your’As-built’Recorddrawing to establish whether you have a distribution box (D-box), which you will also need to unearth and place a riser on if you have a typical gravity system.
- Once the lids have been removed, proceed with caution around the tank.
- Inform someone of your whereabouts in case you are involved in an accident.
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 big 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. Remove any dirt and debris from the tank’s surface by cleaning it off. Using the butyl rope, construct the components of the risers in accordance with the manufacturer’s instructions.
Jet-Set, Rapid-Set, Thorough-Set, and Perco-Plug are just a few of the brand names available.
NOTE: For optimal results, just a little amount of concrete patch should be mixed at a time.
The patch mix should be used to seal the riser to the septic tank.
If you want to avoid a safety danger, make sure you properly attach theriser lid using the screws that come with it!
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.
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.
