Septic Treatment Systems

  • Field
  • Mound
  • LFH at grade
  • Open discharge

Field System

Conventional Field

  • The most traditional type of septic system.
  • Wastewater flows from the septic tank into a series of perforated pipes buried in trenches filled with gravel. The soil filters the wastewater before it reaches the groundwater.
Conventional Septic System

Chamber Field

  • Similar to a conventional system, but instead of gravel-filled trenches, the drainfield has open-bottomed plastic chambers.
  • Offers increased surface area for soil treatment and requires less space than a conventional system.

Drip Distribution Field

  • Uses a network of small-diameter tubing buried in a shallow drainfield.
  • Controlled doses of wastewater are pumped through the tubing, allowing for even distribution and better filtration.
  • Useful in areas with limited space or challenging soil conditions.

Mound System

Mound Systems

  • Used when the natural soil is unsuitable for a traditional drainfield (e.g., too shallow or too much clay).
  • A raised mound of sand and gravel is constructed above the natural ground level to create a suitable drainfield area.

LFH At Grade

Forest Floor Utilization:

  • Designed specifically for forested areas.
  • Relies on the existing LFH (Leaf Forest Humus) layer for wastewater treatment. This layer is the decomposed organic material on the forest floor.

System Design:

  • Requires an Advanced Treatment Unit (ATU) to pre-treat wastewater.
  • Uses pressure distribution and specialized chambers to disperse effluent.
  • Chambers are covered with wood chips, blending with the natural environment.


  • Excellent treatment quality.
  • Minimal disruption to the forest, avoiding tree removal.
LFH At Grade

Open Discharge

  • Environmental and Health Hazards: Open discharge systems release untreated or minimally treated wastewater directly into the environment. This poses severe risks to public health and water quality, contaminating soil and groundwater sources.
  • Legality: These systems are illegal in most developed countries due to the significant environmental and health risks they pose.
  • Ethical Considerations: Promoting open discharge systems could be harmful as they go directly against modern sanitation practices and environmental regulations.

Available Upgrades

Aerobic Treatment Unit (ATU)

  • An advanced system that uses oxygen and bacteria to speed up the natural decomposition process of wastewater.
  • More complex than traditional systems, but produces higher quality effluent.
  • Good option for sites with poor soil conditions or limited space.

Evapotranspiration Systems

  • Used in arid climates with suitable soil conditions.
  • Wastewater flows into a lined bed where it evaporates into the air. Water doesn't reach the groundwater.

Recirculating Sand Filter System

  • Can be constructed above or below ground.
  • Wastewater travels from the septic tank to a pump chamber, then gets pumped into the sand filter.
  • The filter is typically a PVC-lined or concrete box filled with sand.

Sand Filter System

  • Mimics treatment processes found in natural wetlands.
  • Wastewater flows from the septic tank into a constructed wetland cell.
  • Cell contains a liner, gravel, sand, and specially selected wetland plants.

Recirculating Sand Filter System

Recirculating Sand Filter System

  • A type of decentralized wastewater system with common ownership.
  • Serves multiple homes or buildings (often found in rural subdivisions).

Choosing the Right System

The best type of septic system for your property depends on several factors, including:

  • Soil conditions: The type of soil you have will determine how well wastewater can be treated.
  • Space limitations: Some septic systems have smaller footprints than others.
  • Local regulations: Specific regulations may apply to different types of systems.
  • Budget: More advanced systems tend to be more expensive to install.

It's always advisable to consult a professional septic installer or a Registered Onsite Wastewater Practitioner (ROWP) to determine the most appropriate system for your needs.
