Septic Tank Riser Installation Process Explained

Septic tank risers are essential components of a septic system that provide easy access for routine maintenance and inspections. They are typically made of plastic or concrete and are installed to extend from the tank to the surface of the ground. This article will guide you through the process of installing a septic tank riser, highlighting the importance of each step and providing valuable insights to ensure a successful installation.

Understanding the Importance of Septic Tank Risers

Before delving into the installation process, it’s crucial to understand the role of septic tank risers. They serve as access points to the septic tank, making it easier for professionals to pump out the tank, conduct inspections, and perform necessary repairs. Without a riser, you would need to dig up the ground above the tank each time you need access, which can be time-consuming and costly.

Materials Needed for Septic Tank Riser Installation

Before starting the installation process, ensure you have all the necessary materials. These include:

  • Septic tank riser
  • Adhesive or sealant
  • Screws
  • Drill
  • Level
  • Measuring tape

Step-by-Step Guide to Septic Tank Riser Installation

Step 1: Locate and Uncover the Septic Tank

The first step in the installation process is to locate the septic tank. This can be done using a metal detector or probing rod. Once located, dig up the soil above the tank until the lid is exposed.

Step 2: Measure the Opening of the Septic Tank

Using a measuring tape, measure the diameter of the septic tank opening. This measurement is crucial as it will determine the size of the riser you need to purchase.

Step 3: Purchase the Right Riser

With the measurements in hand, purchase a septic tank riser that fits the opening of your tank. Risers come in various materials, but plastic ones are often preferred due to their durability and ease of installation.

Step 4: Attach the Riser to the Septic Tank

Apply adhesive or sealant to the bottom of the riser and place it on the opening of the septic tank. Ensure it’s level and then secure it with screws using a drill. Allow the adhesive to dry as per the manufacturer’s instructions.

Step 5: Install the Riser Lid

Once the adhesive has dried, place the lid on the riser and secure it with screws. Ensure the lid is tightly sealed to prevent any potential leaks or odors.

Benefits of Installing a Septic Tank Riser

Installing a septic tank riser offers several benefits. It simplifies the process of locating the tank, reduces the time and cost of maintenance, and improves the overall efficiency of the septic system. According to a study by the National Environmental Services Center, regular maintenance, facilitated by easy access through risers, can extend the life of a septic system by several years.

Professional Installation vs. DIY

While the process of installing a septic tank riser may seem straightforward, it requires precision and knowledge about septic systems. A poorly installed riser can lead to leaks, which can contaminate the surrounding soil and groundwater. Therefore, unless you have experience with such installations, it’s recommended to hire a professional. A case study by the Environmental Protection Agency highlighted a 60% decrease in septic system failures when professional installation was employed.


Septic tank risers play a crucial role in maintaining the efficiency and longevity of your septic system. While the installation process involves several steps, from locating the tank to securing the riser lid, the benefits it offers in terms of easy access and cost savings make it a worthwhile investment. However, due to the potential risks associated with improper installation, it’s often best to hire a professional to ensure the job is done correctly.
