Septic Tank Risers, Lids, and Covers

Drainage from downspouts and roofs should be directed away from the drainage field. It is possible that additional water from these sources will interfere with the correct operation of your drain field. Four, stay away from the septic tank and drainfield locations with your automobile or truck. The result is a reduction in the likelihood of pipes collapsing and soil consolidation. Soils that have been compacted are unable to absorb water from the drainage system. Fifth, make sure you are using detergent that does not include phosphate.

Additionally, the use of phosphate-free detergents can assist to avoid algal blooms in local lakes and streams.

  1. Risers from the tank lids to the soil surface make it easier to maintain the tank system.
  2. 1.Reduce the amount of time you spend using the trash disposal.
  3. 2 – Avoid the use of “miracle” system cleansers or additions for your septic tank.
  4. Groundwater and surface water might be contaminated by the pollutants as well.
  5. Massive amounts of water are detrimental to the system, and chlorine can kill vital microorganisms that are present in the water.
  6. Avoid flushing solid waste down the toilet or sewer line.
  7. Diapers, cigarette butts, coffee grounds, tampons, condoms, and grease are just a few examples of what may be recycled.
  8. Avoid flushing powerful chemicals down the toilet, such as cleaning products.
  9. Sixth, don’t build patios, carports, or put landscaping plastic on top of a drainage field.
  10. It is impossible for oxygen to enter the earth due to soil compaction and pavement.

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.

  1. The first step is to locate the septic tank. To remove and replace the septic tank lid, search for and locate the septic tank. Identify the type of replacement lid that will be required in Step 2. Utilize a measuring tape to decide the size of lid you will want. Most lids are either 21 inches broad or 24 inches wide, so choose wisely. The third step is to remove and reinstall the Lid.

Aside from that, should septic tank covers be buried? The majority of septic tank components, including the lid, are buried between 4 inches and 4 feet beneath the surface of the earth. You can use a metal probe to detect the boundaries of the object and mark the perimeter of the object. If you are unable to locate the lid by probing, shallow excavation along the tank’s perimeter with a shovel should uncover the lid. Is it true that septic tanks have two 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.

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

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

Jupiterimages/Photos.com/Getty Images is the source of this photograph. With most cases, large concrete lids over manholes and access holes are used to build concrete septic tanks, which are subsequently covered in soil. 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 inspection and maintenance.

The new plastic top is now easily accessible for pumping and maintenance thanks to the addition of a riser to the design. Aside from being bolted down, the plastic lids also provide an additional layer of protection for the homeowner and their family.

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.

Common Septic Tank Facts

Septic systems are a low-cost and frequently successful alternative to conventional sewer systems. Concrete tanks have been the most frequent since the 1940s, with 3 – 500lids for a 1000 gallon tank and 4 – 500lids for a 1500 gallon tank being the most typical. Tanks began to be equipped with 16″ square concrete plugs with a lifting bail in the late 1990s, allowing for easier access to both sides of the tank. Many tanks today are made of fiberglass or plastic. Over time, the concrete might degrade, and the lids may develop cracks or possibly shatter completely due to the pressure.

  • Even broken lids should be replaced for the sake of the public’s safety.
  • They get access to your septic tank by removing green covers that are 20 inches in diameter.
  • This is done in order to prevent anyone, especially children, from removing a lid and falling into the container.
  • A typical water level for a tank should be 6″ below the top of the tank, and the tank should be kept completely filled at all times.
  • The level of the water is often a good sign of potential problems.
  • Additionally, it might suggest a clogged intake line, which could be caused by roots, a damaged pipe, or a loose joint.
  • If there has been a lot of rain, the earth may get saturated, making it impossible for any additional water to seep through the soil to the surface.
  • If your tank has allowed particles to enter the field lines, this might cause the openings in the corrugated pipe to get clogged, preventing water from percolating through the soil as effectively as it should be.

An output filter may be placed to prevent particulates from entering the field lines, but it would need to be cleaned on an annual basis to ensure that this does not happen. Nonetheless, it is far less expensive than rebuilding field lines.
