A soil scientist is someone who is licensed in the practice of soil evaluation. Licensed Soil Scientists have to pass professional exams and meet experience and continuing education requirements.
Request a copy of your septic permit from the local health department and it will show where the tank is approximately located. Probe rods and ground-penetrating radar (GPR) can be used to search underground for the tank lid.
Septic drain fields that are sited upslope of the septic tank require a pump to deliver the wastewater to the drain field. Pressure-distribution systems also require a pump. These systems include low-pressure pipe, drip dispersal, and systems utilizing a pressure manifold to deliver wastewater to a complex drain field layout.
An engineered septic system is required when the soil and site conditions are severely limited. These engineered systems are designed to overcome the complex site constraints with multiple pumps, pre-treatment hydraulic units, and a variety of innovative features. Three Oaks does not currently provide septic system engineering; however, we can put you in contact with a reputable engineer.
A conventional septic system is the most basic on-site subsurface wastewater system. It involves a septic tank, a distribution box, and a drain field consisting of either gravel drain lines or manufactured gravel-less drain lines. Conventional systems require the deepest usable soils (>30″) in order to be installed.
The type of septic system required varies by site and is determined based upon usable soil depth, available space for the drain field, topography, type and amount of wastewater, and other site features that may impact the wastewater system.
