Understanding the Process of Septic System Installation

Posted on: 9 November 2023

Septic systems are designed to effectively handle waste disposal in areas where municipal sewage systems are not available. Whether you’re building a new home or you need to replace an aged septic system, it’s important to understand the basics of the installation process.

Here is a look at how septic system installation works.

Step One: Site Evaluation

Before any actual installation work can begin, a site evaluation must be conducted. Septic system professionals traditionally conduct site evaluations, which will determine the systems' location, size, and type. The evaluation also takes into account the soil and water table levels. The results of the site evaluation will enable the installer to determine the best type of system for the property.

Step Two: Permits & Paperwork

All required permits and paperwork should be obtained and completed before installation. All regulatory agencies should be aware of the system's design, location, and type and obtain the necessary permits before installation work can begin.

Step Three: Excavation & Preparation

The next phase of septic system installation begins with excavation and preparation. Depending on the system's size and capacity, the excavation phase can take a few days. All necessary soil testing will be conducted, and the site will be prepped for the installation work. Tank installation usually follows excavation, with the tank being installed into the ground, reinforced, and inspected.

Step Four: Drain Field Installation

Once the tank is in place, the drain field is installed and connected to the tank. The drain field is composed of trenches filled with gravel and soil and is typically installed after the tank. The drains are installed at a specific depth to allow for proper water flow and filter effluent at the most efficient rate.

Step Five: Final Inspection & System Summary

The final step in the installation process is the final inspection. The installer must inspect the system and ensure it's working correctly. They will also provide a detailed system summary to the homeowner. Typically, a septic system warranty includes annual septic tank and drain-field inspections to ensure they are working as intended.

Septic system installation is an extensive process that is not for the inexperienced. The professional installation team has the expertise, experience, and tools required to ensure that the system is installed in the correct manner. They will also evaluate your property to determine the appropriate system options, obtain all permits, and handle the installation from start to finish. Now, you can rest assured knowing that you understand the process of septic system installation, enabling you to make informed decisions on selecting the right system for your home and property.
