Soil-based Septic System Decisions

The decisions relating to the type of septic system permitted for installation in an area depend on one or both of the following information: 1) observed soil profile properties and 2) an estimate of the degree of water flow through the soil profile. Septic system installation in Oklahoma is regulated by DEQ and the type of septic system permitted is largely based on observed soil properties –mainly soil texture of the porous material as well as soil color and the presence of restricting layers.
