Everything You Need to Know About Septic Tank Riser Installation

A properly functioning septic system is crucial for maintaining the hygiene and sanitation of any property not connected to a municipal sewage system. While septic tanks are buried underground, accessing them for maintenance or repairs can be challenging without proper infrastructure. This is where Septic Tank Riser Installation comes into play.

What is a Septic Tank Riser?

A septic tank riser is a vertical pipe or extension that connects to the access point of a septic tank, allowing easier access to the tank’s interior. Typically made of durable materials like PVC or concrete, risers rise from ground level to the lid of the septic tank, enabling homeowners and technicians to reach the tank without excavating the soil covering it.

Importance of Septic Tank Risers

Installing a septic tank riser offers several benefits, making it an essential addition to any septic system:

Easy Access for Maintenance:

With a riser in place, accessing the septic tank for routine pumping, inspections, or repairs becomes significantly easier and less time-consuming. This accessibility saves homeowners and technicians effort and reduces the disruption to the surrounding landscape.


While initially an investment, installing a septic tank riser can save money in the long run. It eliminates the need for repeated excavation each time the tank requires servicing, reducing labor costs and potential damage to the yard.

Preventative Maintenance:

Regular maintenance is crucial for the longevity and efficiency of a septic system. With a riser installed, homeowners are more likely to adhere to maintenance schedules, as the process is simplified and less intrusive.

Enhanced Safety:

Without a riser, accessing a septic tank involves digging, which poses safety risks such as cave-ins or injuries from tools. Risers eliminate these hazards by providing a safe and stable access point to the tank.

Steps for Septic Tank Riser Installation


Before installation, assess the location and condition of the septic tank to determine the appropriate size and type of riser needed.

Gather Materials:

Acquire the necessary materials, including riser sections, adapters, sealant, and tools such as a saw and drill.


Dig around the access point of the septic tank to expose the lid and create space for the riser.


Assemble the riser sections according to the manufacturer’s instructions, ensuring a secure fit. Use sealant and adapters to connect the riser to the tank.


Place the assembled riser over the access point and secure it in place. Backfill soil around the riser to stabilize it.


Perform a visual inspection and test the integrity of the installation to ensure proper sealing and stability.
