Materials and Tools Needed

Before we delve into the details, let’s gather all the necessary materials and tools. Here’s what you’ll need:


  1. Concrete riser ring
  2. Concrete mix
  3. Reinforcement mesh
  4. Gravel
  5. PVC pipe (for ventilation)
  6. Septic tank lid


  1. Shovel
  2. Level
  3. Tape measure
  4. Trowel
  5. Wheelbarrow
  6. Safety gear (gloves, safety glasses, and a mask)

Step-by-Step Guide

1. Choose the Location

  • Select a suitable location near your septic tank for the riser installation. Ensure it is easily accessible and not obstructed by any structures.

2. Measure and Dig

  • Use a tape measure to determine the required depth for the riser. Typically, it should be level with the ground. Dig a hole accordingly, making sure it’s wide enough to accommodate the concrete ring.

3. Create a Base

  • Place a layer of gravel at the bottom of the hole for proper drainage and stability. Use a level to ensure the gravel is evenly spread.

4. Set the Concrete Ring

  • Lower the concrete riser ring into the hole. Make sure it sits level with the ground surface. Adjust the gravel base if necessary.

5. Mix and Pour Concrete

  • Follow the instructions on the concrete mix bag to prepare the concrete. Pour it into the riser ring, filling it to the top. Use a trowel to smooth the surface and ensure it’s level.

6. Add Reinforcement Mesh

  • Place a reinforcement mesh inside the concrete to strengthen it. This will prevent cracking over time. Ensure the mesh is centered within the concrete.

7. Install PVC Ventilation Pipe

  • Insert a PVC pipe into the concrete before it dries. This pipe will provide ventilation for the septic tank, preventing unpleasant odors.

8. Let it Cure

  • Allow the concrete to cure for the recommended time mentioned on the concrete mix bag. This typically takes a few days.

9. Attach the Septic Tank Lid

  • Once the concrete is fully cured, attach the septic tank lid securely to the riser. Make sure it’s sealed properly to prevent any leaks.

10. Backfill and Finish

  • Fill the remaining gap around the riser with soil. Tamp it down firmly to ensure stability. The riser should now be level with the surrounding ground.

Protect the Riser

  • Be cautious when mowing your lawn or performing any other activities near the septic tank riser. Avoid heavy equipment or vehicles driving over it, as this can cause damage.

Consult a Professional

  • If you’re unsure about any step in the installation process or encounter any issues, don’t hesitate to consult a professional septic system technician. They can provide expert guidance and ensure the job is done correctly.

Keep Records

  • Maintain records of all maintenance and inspection activities related to your septic tank riser. This documentation can be valuable for future reference and potential home sales.

Consider Local Regulations

  • Check with your local authorities and regulatory agencies to ensure that your septic tank riser installation complies with any specific codes or regulations in your area. Compliance is crucial to avoid legal issues in the future.

Maintaining Your Septic Tank Riser

Now that you have successfully installed your septic tank riser, it’s essential to understand how to keep it in excellent condition. Proper maintenance is crucial to ensure it continues to serve its purpose effectively.

Inspection Schedule

  • Establish a routine inspection schedule for your septic tank riser. Check it at least once a year, but more frequent inspections, especially during heavy usage periods, can be beneficial.

Remove Debris

  • Regularly remove leaves, dirt, and other debris from the area around the riser and the lid. This prevents clogs and ensures easy access when needed.

Monitor for Leaks

  • Keep an eye out for any signs of leakage around the riser or lid. If you notice any, it’s essential to address the issue promptly to prevent contamination.

Check the Ventilation Pipe

  • Ensure that the PVC ventilation pipe remains unobstructed. Blocked pipes can lead to unpleasant odors and poor septic system performance.

Sealing Gaskets

  • Periodically inspect the sealing gaskets on the septic tank lid to ensure they are in good condition. Replace them if they show signs of wear or damage.

The Benefits of a Septic Tank Riser


  • Having a septic tank riser means you no longer have to dig up your yard to access the tank. Routine maintenance, inspections, and pumping become much easier and less labor-intensive.


  • While there is an initial cost associated with installation, a septic tank riser can save you money in the long run by reducing the time and effort required for maintenance.

Environmental Protection

  • A well-maintained septic system with a riser is less likely to experience leaks or failures, minimizing the risk of groundwater contamination and environmental damage.

Increased Property Value

  • If you decide to sell your property, a septic tank riser can be an attractive feature for potential buyers, as it demonstrates responsible septic system management.


Congratulations! You have successfully created a septic tank riser, enhancing the accessibility and functionality of your septic system. Regular maintenance and inspection are essential for the longevity of your septic tank, and with this riser in place, the process becomes much simpler.
