Installing A New Septic System

If you’re planning to install a new septic system, it’s important to follow the proper steps to ensure its effectiveness and longevity.

1. Perc Test: Ensuring Proper Soil Conditions

   The first step in installing a new septic system is to conduct a perc test, also known as a percolation test. This test determines the soil’s ability to absorb and filter wastewater from the septic system. It involves digging test holes in the proposed drain field area and measuring the rate at which water percolates into the soil.
   The results of the perc test will determine the size and design of the septic system that can be installed on the site. It’s crucial to ensure that the soil conditions are suitable for a septic system to function properly and prevent groundwater contamination.
2. Choosing the Septic Design: Customizing for Optimal Performance

   Once the perc test results are available, the next step is to choose the septic design that best fits the site’s conditions. A well-designed septic system should take into consideration factors such as soil type, slope, proximity to water sources, and local regulations. It’s essential to work with a professional septic designer or engineer to customize the system for optimal performance.
   The septic design should include the location of the septic tank, drain field, and other necessary components, as well as the layout of pipes and distribution lines. A properly designed septic system will ensure effective treatment of wastewater and prevent environmental hazards.

3. Applying for a Permit: Complying with Local Regulations

   Before starting the installation process, it’s important to obtain the necessary permits from the local regulatory authorities. The requirements for septic system permits vary depending on the location, and it’s crucial to comply with all local regulations. This may involve submitting the septic design plans, perc test results, and other relevant documentation to the local health department or building department for review and approval.
   It’s important to be aware of any zoning restrictions, setback requirements, or other regulations that may affect the installation of the septic system. Obtaining the necessary permits is a crucial step in ensuring that your septic system is installed legally and meets all regulatory requirements.

4. Excavating the Site: Preparing for Installation

   Once the necessary permits are obtained, the next step is to prepare the site for installation. This involves clearing the area of any vegetation, debris, or obstructions that may interfere with the installation process. The site should be leveled, and the area for the septic tank and drain field should be marked according to the septic design plans.
   Excavation equipment, such as a backhoe or excavator, may be used to dig the holes for the septic tank and drain field. It’s essential to follow the septic design plans carefully and ensure that the dimensions and depths of the holes are accurate to accommodate the septic system components.
5. Installing the Septic Tank: Proper Placement and Connection

   Once the excavation is complete, the septic tank can be installed according to the septic design plans. The septic tank should be carefully placed in the excavated hole, ensuring that it is level and stable.
   The inlet and outlet pipes of the septic tank should be properly connected to the house plumbing system. It’s important to ensure that the connections are secure and watertight to prevent leaks or sewer backups. The septic tank should also be vented to allow for proper airflow and gas release.

6. Installing a Drain Field: Proper Distribution of Wastewater

   The next step is to install the drain field. The size and layout of the drain field is determined by the septic design plans and the perc test results.

7. Backfilling the Site: Properly Refilling the Excavated Area

   Backfilling involves filling the excavated holes with the appropriate type of soil. This is typically the same soil that was removed during excavation. The soil should be carefully compacted in layers to prevent settling or shifting of the septic system components.
