Types of Septic Design

There are various types of septic design options available, and at D R Excavation, we offer expertise in each of them. Some of the common types of septic design include:

  • Conventional Septic System Design

    This is the traditional septic system design that consists of a septic tank and a drainfield. It is suitable for properties with sufficient space and soil conditions that allow for proper wastewater treatment.

  • Gravity Septic System Design

    This design relies on gravity to move wastewater from the septic tank to the drainfield. It is a cost-effective option that works well for properties with a slope that allows for natural flow.

  • Pressure Distribution System Design

    In this design, a pump is used to evenly distribute wastewater throughout the drainfield. It is suitable for properties with challenging topography or soil conditions that require enhanced distribution.

  • Mound Septic System Design

    This design is suitable for properties with high water tables or poor soil conditions. It involves constructing an elevated mound to accommodate the drainfield and ensure proper wastewater treatment.

  • Chamber Septic System Design

    This design utilizes chambers to distribute wastewater evenly in the drainfield. It offers increased efficiency and flexibility in design, making it suitable for various property types.

  • Aerobic Treatment Unit (ATU) Design

    An ATU design incorporates additional treatment processes to further purify wastewater. It is an ideal option for properties with specific requirements for water quality or where advanced treatment is necessary.

  • Drip Irrigation Septic System Design

    This design involves the controlled distribution of treated wastewater through drip irrigation lines. It is a suitable option for properties with limited space or soil conditions that require precise distribution.

  • Sand Filter Septic System Design

    This design utilizes sand filters to remove impurities from wastewater before it enters the drainfield. It is an effective option for properties with challenging soil conditions or where additional treatment is required.

  • Advanced Treatment System Design

    At D R Excavation, we offer advanced treatment system design options that incorporate innovative technologies for enhanced wastewater treatment. These systems are designed to meet specific property requirements and environmental considerations.
