124 Neb. Admin. Code, ch. 1, § 055 - "Mound system"
"Mound system" means an onsite wastewater treatment system that includes a septic tank for primary treatment, an effluent pumping system, and a soil absorption system that includes a pressurized effluent distribution system within a prescribed layer of rock or acceptable treatment media that is elevated above the original ground surface by a layer of clean sand. The distribution system is pressure dosed to provide uniform distribution of effluent over the entire layer of treatment media, and treatment media is capped by a protective layer of geotextile fabric (to prevent fine material intrusion from the soil), soil, and grass.
