01Site Evaluation

  • Before installing a septic system, it's essential to evaluate the site thoroughly. This evaluation helps determine the suitability and capacity of the soil to treat and dispose of wastewater.
  • Engage the services of a professional soil scientist or engineer to conduct a site evaluation. They will assess factors such as soil type, depth to water table, slope, and available space for the drainfield.
  • A perk test, or soil evaluation test, is typically performed to determine the absorption rate of the soil. This test helps determine the required size of the drainfield.
  • Ensure compliance with local regulations and obtain any necessary permits before proceeding with the installation process.

02System Design

  • Based on the site evaluation, a septic system design should be created. This design takes into account the soil conditions, site layout, and estimated wastewater flow.
  • Design considerations include determining the appropriate size of the septic tank, the type of drainfield system, and the overall layout of the system.
  • Engage a licensed designer or engineer experienced in septic system design to create an efficient and compliant system design.
  • Review the design with local health department officials or regulatory agencies to ensure compliance with local regulations.

03Excavation and Tank Installation

  • The first step in the installation process is excavating the area for the septic tank and drainfield. Follow the design specifications and local regulations for the required depth and size of the excavated area.
  • Excavate the area carefully, taking into account any nearby structures or trees that could interfere with the system's operation.
  • Install the septic tank in the excavated area, ensuring it is level and properly supported. The tank should be positioned according to the design specifications and adequately sealed to prevent leaks.
  • Connect the septic tank to the building's plumbing system, ensuring a secure and watertight connection.

04Drainfield Installation

  • After the septic tank is installed, the drainfield can be constructed. The drainfield, also known as the leach field, is responsible for distributing clarified wastewater into the soil for further treatment and disposal.
  • Follow the design specifications for the layout and size of the drainfield trenches. Excavate the trenches accordingly, ensuring the proper depth and spacing.
  • Install the necessary distribution pipes and gravel in the trenches. These pipes evenly distribute the wastewater into the soil to promote efficient absorption and treatment.
  • Cover the drainfield trenches with soil, taking care not to compact it excessively. This allows for adequate oxygen flow and promotes microbial activity in the soil.
  • Install inspection ports or risers for easy access to the drainfield for maintenance and monitoring purposes.

05Final Connections and Testing

  • Once the septic tank and drainfield are installed, make the necessary final connections to complete the system.
  • Connect the outlet pipe from the septic tank to the inlet of the drainfield distribution pipe system. Ensure all connections are watertight and properly sealed.
  • Perform pressure tests or dye tests to check for any leaks or blockages in the system. Address any issues before finalizing the installation.
  • Schedule a final inspection with the local health department or regulatory agency to ensure compliance with all regulations and standards.
