Leach Field Vent Pipe

Septic Drain fields are also known as Soil Treatment Areas or Leach Fields. They are subsurface wastewater disposal systems that remove contaminants and impurities from liquids discharged by a system with septic tanks.

A “candycane” is a component you may see. The vent pipe that allows air to circulate in the leaching area is called a “candy cane”. Vent pipes can be used to vent the leaching fields.

The ventilation pipe’s purpose is to supply oxygen to the drain field, where aerobic bacteria lives. The field’s lower vent allows air to pass through the plumbing of the roof and into the house. The ventilation pipe at the other end of the field is not required to allow air to flow through the field.

Leach Field

A leach field, also known as a drain field, is a collection of rows of perforated pipe that are buried in gravel pits from 18 to 36 inches below grade. This allows air to pass through the pipes and allow bacteria to further purify the effluent. The distance from the surface to the soil may vary depending on the type of soil and the local codes.

Vent Pipe

Perforated pipe in gravel beds is not the best option for a durable, long-lasting septic system. Infiltrator chambers are superior to pipe-in gravel in all aspects: smaller leach fields due to optimal percolation; increased retention capacity for heavy loading days; root infiltration protection for long-term viability; resistance to traffic and more. The infiltrator chamber leach field chambers consist of high-density polyethylene arches which interlock to form continuous drainage areas with a greater storage volume than traditional pipe-in-gravel. The chamber fields have a 30 percent reduction in field size than pipe in gravel.

The Main Components Of The System Are:

  1. Inlet pipe: This directs waste from your home to the septic tanks
  2. Outlet pipe: This is where the separate effluent leaves the septic tank
  3. Leaching field: A set of drainage pipes that allows for the further filtration of liquid effluent into the environment’s groundwater.
  4. Septic tank: This is where the liquid effluent separates and the solid sludge.
  5. Distribution box: Distributes liquid effluent to the leaching lines

Increase The Vent Pipe’s Height

The ventilation pipe, as mentioned above, is responsible for venting the gases and air from the septic tank. The pipe’s height can be increased to allow the release of odors. This allows for the ventilation air to be blown over the structure by wind.

Perforated pipes are covered with gravel about 2 inches thick and topsoil approximately 18-24 inches deep. The topsoil is kept from getting clogged by the geotextile (or hay) in the olden days. Grass is typically planted above. The grass removes excess moisture from the soil and does not send down roots that could block the pipes.

Is A Vent Pipe Necessary For A Septic Tank?

Your septic system, and all sewage systems in general, require a venting system. This allows gases to escape the system, preventing dangerous buildups or airlocks. Three methods of pipe ventilation should be available for your septic system: Inlet & Outlet and Roof-Vent.

Alternatives To Leach Field

Another possible solution is bio-remediation. It is a special-formulated bacteria that we use to treat a problem area. After it is injected into the system, it eats up any bio-mat.

TERRALIFT – Terralift machines use this to lift the leach fields. A probe is inserted into the ground at 6 feet. The compressor then injects air and beads of polystyrene. This causes ground to fracture and allows water to leak back into it.
