DIY Septic Tank Riser Installation Guide

Septic tank risers are essential components of a septic system that provide easy access for routine maintenance and inspections. They are typically installed at ground level, making it easier to locate and access the septic tank. This article provides a comprehensive guide on how to install septic tank risers yourself, saving you the cost of professional installation.

Understanding Septic Tank Risers

Before diving into the installation process, it’s crucial to understand what septic tank risers are and their role in a septic system. A septic tank riser is a pipe connected to the septic tank to create an above-ground access point. They are usually made from PVC, polyethylene, or concrete, and come in various sizes to fit different septic tanks.

Benefits of Installing Septic Tank Risers

Installing septic tank risers offers several benefits:

  • Easy access for maintenance and inspection
  • Reduced need for digging
  • Time and cost savings
  • Prevention of accidental damage to the septic tank

Materials Needed for Septic Tank Riser Installation

Before starting the installation process, ensure you have the following materials:

  • Septic tank riser and lid
  • Butyl rope sealant
  • Stainless steel screws
  • Power drill
  • Shovel
  • Level

Steps to Install a Septic Tank Riser

1. Locate the Septic Tank

The first step is to locate your septic tank. This can be done using a metal detector or probing rod. Once located, mark the area for digging.

2. Dig to Expose the Septic Tank Lid

Using a shovel, dig down to the septic tank lid. Be careful not to damage any pipes or the tank itself. Once the lid is exposed, remove it.

3. Prepare the Riser

Apply the butyl rope sealant around the base of the riser. This helps create a watertight seal between the riser and the septic tank.

4. Attach the Riser to the Septic Tank

Place the riser over the opening of the septic tank. Ensure it’s level before securing it with stainless steel screws using a power drill.

5. Install the Lid

Once the riser is securely attached, install the lid. Make sure it fits snugly and securely.

6. Backfill the Area

Finally, backfill the area around the riser with soil, being careful not to damage the riser or lid.

Considerations When Installing Septic Tank Risers

While installing a septic tank riser can be a straightforward DIY project, there are a few considerations to keep in mind:

  • Ensure you have the correct size riser for your septic tank.
  • Always check local regulations as some areas may require professional installation.
  • Consider safety precautions when digging, such as wearing gloves and protective eyewear.
  • Ensure the riser is level to prevent potential leakage.


Installing a septic tank riser can be a cost-effective and practical DIY project for homeowners. It provides easy access for routine maintenance and inspections, saving time and money in the long run. With the right materials and a bit of patience, you can successfully install a septic tank riser yourself. However, always remember to check local regulations and consider safety precautions when undertaking this project.
