ABSTRACT:
Liquid waste material passes from a septic tank to a holding tank prior to being pumped into a tiled drain field. The liquid waste material is only pumped into the drain field when the liquid saturation of the soil in and around the drain field is below a predetermined level. The saturation level is determined by RF admittance sensing probes which extend into the soil in the area of the drain field.
