A septic riser is a system component that helps people to get into the tank. This is like most stairs or steps that go down to your wastewater treatment systems, allowing for easier inspection and cleaning. Here are various types of septic risers and their pros and cons.

Types of Septic Risers

Types of Septic Tank Risers

  1. Concrete Septic Tank Risers

These powerful cinder blocks allow you to access your septic tank easily. They are solid; thus, they can last long without breaking. Therefore, you do not have to replace them frequently, which is advantageous because you save money in the long run.  However, concrete risers tend to be slightly more expensive initially than other kinds.

Advantages of Concrete Septic Tank Risers

Strong and Durable

Concrete risers are rigid but can last for a while without breaking. This means less frequent replacements, hence cost savings over time.

Stable Support

They offer a stable platform where one can reach their septic tank, making maintenance easier and thereby reducing potential safety risks.

Weather Resistant

Unlike other materials, concrete risers can withstand different weather conditions and remain reliable as time goes by.

Disadvantages of Concrete Septic Tank Risers

Initial Cost

Compared to other materials, these may be costly initially, especially when installed as new units, and therefore, may not favour people with insufficient funds.

Heavy to Handle 

Due to their weightiness, transporting concrete risers may involve lifting them high above the ground level before positioning them correctly.

Potential for Cracks 

As time moves on, this kind of material develops cracks. Such structural issues only come if they are not properly maintained.

  1. Polyethylene Septic Risers 

They are made of lightweight material that can be easily handled and are available in different sizes to suit various septic tank arrangements. They are long-lasting plastics that can withstand the pressures of being part of a septic system.



Polyethylene risers are lighter than other materials, such as concrete. As a result, they can be easily handled during installation without requiring assistance from heavy machinery or the workforce.

Versatile Sizes

Various septic tank setups will fit these risers since they come in different heights. This makes it possible to install them according to specific requirements.

Ease of Maintenance

Maintenance of polyethylene risers is straightforward. These require far little attention compared to heavier ones, while durability ensures fewer efforts for their lifespan.


Limited Strength

Materials such as concrete may be more robust than polyethylene risers, exposing them to damage through heavy objects or pressure.

Durability Concerns

These materials may not last as long as more robust options, needing more frequent replacements.

Aesthetic Considerations

The appearance of polyethylene and PVC risers may not appeal to all people. Compared with other types, the friendly nature affects the outlook on the structure design of a septic system when made using this material (Koontz & Hayslip, 2016).

  1. Polyvinyl Chloride (PVC) Septic Risers

Polyvinyl chloride is a durable plastic used to make PVC septic risers. Being lightweight and coming in various sizes helps them fit into different configurations for septic tanks. They make it easier to access the septic system for maintenance and inspection purposes.

Advantages of PVC Septic Risers


PVC risers are lightweight, making them easy to manipulate and install. Thus, they are helpful in DIY projects or where you do not want to lift heavy materials.


The integrity of PVC risers is maintained through their corrosion-resistant properties. Environmental factors cannot easily damage them.

Versatile Sizes

Different heights and diameters characterize PVC risers. They can, therefore, be adjusted for different septic tanks and any specific installation demands.

Cons of PVC Septic Risers

Limited Strength

Compared with materials such as concrete, PVC might not have much strength. This means it may get damaged by heavy objects or pressure more easily.

Durability Concerns

PVC can last long but not as long as some other strong materials. Because of this, one may need to replace them more frequently due to wear and tear.

  1. Fiberglass Risers:

Fibreglass risers are made from a rigid material called fibreglass. It has resistance against corrosion and harsh weather conditions. These risers weigh little and are conveniently handled during their installation process. They contribute to assured access to the septic tanks throughout a very long period.

Advantages of Fiberglass Risers


Because of their corrosion-resistant properties, fibreglass risers will stay strong over time, even in harsh environments.


The ease with which fibreglass risers can be transported and installed is attributed to their lightweight, reducing the efforts needed to set up and maintain them.

Disadvantages of Fiberglass Risers

Higher Cost

Purchasing fibreglass riser panels may have higher initial costs than other materials. However, people on tighter budgets may find this limiting factor discouraging since it sometimes means going for cheaper alternatives rather than these primarily.

Careful Handling Needed

Fibreglass risers could require more careful handling when put into position during the installation process. This maintains the setup process by avoiding any damage experienced and adds an element of caution.


Knowing the different kinds of septic tank risers and their advantages and disadvantages may help you make informed choices. Each material has pros and cons, whether concrete, plastic or fibreglass riser pans. Please approach us if you need advice on septic tank risers or consultation.
