Why Are My Septic Tank Risers Wrapped In Plastic? (TOP 5 Tips)

  • Our septic tank risers and lids are made of high density polyethylene plastic which gives them strength for direct burial and foot traffic, but also makes them lightweight for easy handling during installation and removal of the lid. The Polylok risers and lids are available in 12”, 20”, and 24” diameter.

Should septic tank lids be covered?

The lid covers should fit tightly — if they don’t, a company that specializes in septic repairs should be called to fix them. A septic tank stores the solids from drains and needs to be pumped out about every two years, so it’s not a good idea to cover the area — you need to always be sure where to find the tank.

Do septic tanks need to be airtight?

Septic tanks need to be watertight. The riser should be sealed to the top of the tank and the riser cover should be sealed to the riser with butyl rubber or some other flexible sealant. No liquid should enter or leave the tank.

What is the purpose of septic tank riser?

A septic tank riser is a pipe made of either plastic, fiberglass, or concrete. It creates a vertical portal at the ground surface for easy access to the septic tank for inspection and pumping out. The lid is then either left exposed or with a very thin layer of soil and grass over it.

How do you insulate a septic tank riser?

How to Insulate Septic Tank Risers

  1. Remove soil around the septic tank riser with the excavator.
  2. Measure the circumference of the riser and cut the insulation to this measurement with a sharp knife.
  3. Apply the adhesive to the insulation to the insulation and to the riser material.
  4. Wrap the insulation around the riser.

How are septic tank lids measured?

Dig a 30” diameter hole down to the inlet chamber lid. Open the lid and look for the end wall where the 4” sewer pipe comes into the tank from the house. Once you determine where the inlet is, measure the distance from the center of the inlet lid towards the opposite end of the tank to locate the outlet lid.

Are all septic tank lids round?

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

Should septic tank riser be above ground?

Landscaping Around Septic Tank Risers However, septic tank risers should never be buried. Instead, they should be 2 inches above final grade to prevent groundwater from entering the system.

Are septic tank risers safe?

Fortunately, lids and risers in today’s onsite market can help prevent these unfortunate incidents. These innovative products ensure septic tank covers are secure and prohibit unauthorized tank access. Polyethylene septic tank covers from Hedstrom Plastics fit standard 18- and 24-inch double-wall corrugated pipe.

Can you cover septic tank lids?

If you have a traditional septic system, the tank should be pumped every 3-5 years. That means that the septic lids should be accessible every 3-5 years. You can use almost any temporary, movable objects to cover your lids, like: Mulch (but not landscaping)

Should a septic tank have a breather?

The tank and its plumbing system are sealed, which means the air inside is trapped. This is why proper venting of a septic tank and the system are crucial. All of the gases are to be vented back through the house and out of the vents in the roof.

Do septic tanks need an air vent?

The bacteria active in a septic tank are anaerobic. Anaerobic means the bacteria operate without oxygen from the air. There is not a great deal of gas generated in a septic tank, but the gas must be released so pressure does not build up in the tank. If the septic tank has inlet and outlet baffles, they must be vented.

Can I cut my septic vent pipe in yard?

They shouldn’t be removed but they can be cut down, level with the ground. Other white pipes may be standing above your septic tank, pump tank or close to your foundation. Those are available for maintenance, if needed, and shouldn’t be removed. Again, they can all be cut down close to the ground surface and recapped.

What You Should Know About Septic Tank Risers

Septic tank risers are an important part of any septic system, and they should be installed in every property. This article will provide you an overview of septic tank risers and how they may help your septic system. What Is the Function of a Septic Tank Riser? A septic tank riser is a conduit that connects your home’s surface drainage system to your septic tank beneath the ground level. An access port or the pump-out ports on the septic tank are where the riser connects to the tank. Septic tank risers are equipped with lids that can be quickly removed to allow you to check or pump your septic tank without having to dig up your yard.

These structures are often made of materials that disintegrate slowly over time, such as plastic or concrete.

What Are the Advantages of Using Risers?

Normally, this entails digging up your yard before the pump is installed and reburying the tank once it has been installed.

  1. The use of a septic tank riser can help to minimize the amount of time spent pumping your septic tank.
  2. The fact that the riser is visible above the surface of your yard makes it an ideal signal for locating your septic tank the first time you need to discover one in your yard.
  3. For those who want to stay in their house for several years, septic tank risers are not only handy, but they are also cost-effective.
  4. Concrete risers are more durable, but they are also more expensive, and the price will be determined by the quote you receive from the contractor who will be installing them.
  5. Because labor expenses account for a large amount of the fees that contractors charge for septic system inspection and pumping, installing a riser may possibly reduce the future cost of septic service by as much as 50 percent.
  6. Each and every property can profit from the installation of a septic tank riser, but this does not imply that you should do so immediately.
  7. This allows for the installation of the pump and riser to be completed in a single step.
  8. Because a riser should be considered a long-term investment, you should be certain that your tank is in good functioning shape before installing one.
  9. A septic tank riser is a straightforward concept that may save you a significant amount of money and pain when it comes to septic system maintenance and repair.

Making Septic Tank Access Easier

Because of this, I don’t believe I’ll cut the culvert at an angle in the future. I believe that having a level lid simply looks better! When I initially noticed how near my access lids were to the tank’s exterior walls, I was a little concerned, but it turns out that was by design. The fact that a round riser would not fit exactly against the concrete top of the tank made me understand that a section of the round riser would have to extend out beyond the outer wall of the septic tank, with just earth beneath it, was something I had overlooked.

  • Sorry, but the tape measurements are a little difficult to read.
  • This is one of the reasons I’m waiting doing anything as I think about it more thoroughly.
  • However, I’d forego using the concrete anchor bolts since I’m concerned about damaging the concrete septic tank cover.
  • As far as I can see, getting rid of the concrete lids has the advantage of requiring far less muscle to remove the plastic riser lid.

For this reason, filling the two holes with shipping popcorn or multiple layers of foam boards cut into 2′ x 2′ squares, and then covering with a decorative large diameter patio paver over each to mark the location and an inch or two of dirt or mulch (just sufficient to cover the foam), with the concrete tank lids still in place, is more appealing to me.

I believe it is intended for the purpose of filling gaps around windows and doors, rather than sealing concrete lids.

I agree with you that rain will not significantly increase the burden.

It is my intention to develop comparable instruments and to measure the scumsludge levels by removing simply the outlet lid (after all, it is closer to grade level and weights a lot less), so that I can determine whether the layers accumulate at the pace that requires my tank to be pumped on a regular basis (almost 6 years for a 1000 gallon tank and a household of 2 people).

  1. In addition, I have a filter on my washing machine that captures the majority of the lint from the machine’s waste water, preventing it from entering the septic tank.
  2. I need to create a compost pile in order to redirect the majority of our organic waste away from the drain; unfortunately, the majority of this garbage does not go down the drain but instead into the trash can.
  3. That had to be snipped out of the roof’s air stack with a snake!
  4. The fact that it was examined is a good thing, otherwise I can only picture the type of plumbing backlog that may have occurred.
  5. You might say that was part of the “new system”: a new tank, along with a new finger system.
  6. My system appears to be functioning normally in the absence of it.
  7. Isn’t it possible that the majority of the toilet paper and other “floaties” would accumulate in the baffle and cause the incoming stream to back up?
  8. Due to the fact that I had identified and dug up both of the pumpers, it only took 45 minutes for them to pump out my tank!

Thank you very much for all of your comments and suggestions! I’ll publish some photos of whatever it is that I decide to undertake ” (“official” riser, culvert and lid, bags of shipping popcorn or layers of 1″ foam board crowned with pretty patio pavers). Regards, Cuz.

Receive articles, stories, and videos about septic tanks delivered directly to your email! Now is the time to sign up. Septic Tanks and More Receive Notifications We receive a constant stream of queries concerning how to install risers and, by extension, how to install the lids on those risers. One of the most prevalent themes we hear when it comes to system installation is that systems must be built with monitoring and maintenance in mind. This implies that all components must be fitted in a way that allows them to be readily reached by experts and that allows them to be repaired or replaced when necessary.

As a result, offering cost-effective service is dependent on providing quick access.

This makes the task of the service provider or inspector while examining the state of the tank, as well as the duty of the pumping contractor when the tank is full, a whole lot easier to do.


There are several different types of rims and lids available, including concrete, polyethylene, polypropylene, polyvinyl chloride, and fiberglass. No matter what material is used, the riser and the connection to the tank or additional risers must be waterproof and resistant to root intrusion. If roots are able to get through, the structure is not waterproof! Risers should also be structurally stable, so that they do not lose their form after backfilling with concrete. In the case of concrete tanks, a riser is frequently cast into the tank during the manufacturing process.

  • If you live in a cold area, you will benefit from using cast-in-place risers since they are less susceptible to frost heave, which causes risers linked with joints to split over the winter and impairs watertightness.
  • The majority of what we’ve seen so far includes casting an adapter ring into the tank hole, which is advantageous because having risers cast in place might interfere with setting the tank and being in the way when the system is fitted.
  • It is critical to follow the manufacturer’s directions while applying sealants to guarantee that the building is waterproof.
  • Watertightness is achieved by the use of mastic and other sealants.
  • This is the standard layout for tanks that are newly constructed.

As an installation or service provider, on the other hand, you are frequently confronted with older concrete tanks that do not have a built-in riser. As a result, an upgrade is required to bring a riser to the surface for future service convenience.


Making these connections completely waterproof is a difficult task. We frequently encounter a riser that is somewhat bigger or of a different shape than the current aperture (round versus square), mostly because it is the most readily available option on the market. It is then placed over the top of the tank lid in an attempt to mortar them into place, before being removed. They are readily loosened, and when the tank is opened, it is discovered that water and soil have been introduced into the tank through this connector.

  1. The good news is that new items to assist with this issue are being accessible all of the time, which is encouraging.
  2. Most polyethylene and fiberglass tanks will have risers incorporated into them at the time of production, unless otherwise specified.
  3. To keep children and animals out, lids must be built of sturdy materials with connections that are both water- and air-tight, and they must be kept closed when not in use.
  4. Homeowners may also object to lids that are visible on the surface of the water.
  5. Service providers can utilize a metal detector to find the tank entry point in a short amount of time.

We believe it is preferable to have the lids raised a couple of inches above the surface of the water to make it easier for the service provider to reach the water. It is critical, however, that the lid is secured with nonstandard bolts or screws to ensure that minors, in particular, are unable to open it. Every year, we receive a number of instances of youngsters falling into septic tanks and being gravely hurt or killed because the lid has not been properly affixed to the riser, as is often the case.

These devices are available for purchase separately.

Purchasing this insurance coverage and upgrading their system may prove to be a wise investment.

In most cases, this results in riser deformation and a lack of watertightness, as well as the creation of a dangerous access problem.

It is expected that following these principles would make tank entry and servicing easier, resulting in better maintenance for septic systems and a longer service life for them.

Clean Looking Septic Systems

You are not required to have an unsightly septic system! The majority of septic systems are composed of three components: the pretreatment tanks, which are often septic tanks or aerobic treatment plants, the distribution system (which may be either gravity or pumped), and the absorption system (which can be either gravity or pumped). Each component can be handled in a somewhat different manner than the others. Let’s take a look at each of the components one by one. When concrete lids are on or above grade, septic tanks can be ugly due to the weight of the concrete.

  1. The installation of suitable risers on septic tanks as well as green plastic covers that are fastened down can help to clean them up and make them more robust while also being more visually pleasant to the eye.
  2. They must be at grade in the event that the septic tank’s components need to be replaced or repaired.
  3. Absorption zones or drain fields that have been pressure dosed may have lateral cleanouts that are above ground level.
  4. This can not only be unattractive to look at, but it can also be a health threat if untreated sewage is allowed to seep to the top of the water table.
  5. This will enable for maintenance access while also being able to be mowed over without disrupting the septic system.
