Pressure Distribution Septic Fields

In pressure distribution fields the effluent is pumped out of the Dose Tank and through an inline filter system using a high capacity pump. The effluent flows through PVC piping system to the excavated field area. In the field area trenches are excavated laterally to a maximum depth of 36” and a maximum length of 65’. In these trenches (called laterals) we install smaller diameter PVC pipes which are held off the ground by pipe stands. These pipes are drilled every 36” to create orifices which simulate an underground sprinkler system. Then we cover the pipes over with the plastic chamber components which create the long hollow void space. Once the system is energized by the septic pump then the entire surface area of the whole septic field is watered evenly and consistently.


  • The entire surface area of the septic field receives an equal dosage of effluent which, compared to conventional gravity fed septic systems, eliminates overloading the first section of any lateral. Pressure distribution septic fields are more efficient in processing the effluent due to the consistent effluent distribution which allows the bacteria to decompose nutrients and the soil structure to drain and filter the wastewater.


  • The pressurized lines will become contaminated with mineral residue over time and will start to plug the spray holes. These lateral distribution lines require periodic flushing and maintenance depending on the minerals and contaminants within the household water and sewage. The life span will be lengthened substantially by cleaning the inline filter bi-annually.
