Presby Enviro Septic is a type of absorption and secondary treatment system that uses 12"-diameter perforated pipes wrapped with a special fabric that promotes and hosts bacterial growth. Once established, this "controlled bio-mat" cleans the effluent as it passes through the fabric.
Benefits of on-site wastewater treatment include:
Localization of treatment and dispersal--eliminating long distance transport of wastewater to treatment plants and purified water back to point of origin
Recycling of wastewater, recharging groundwater within the watershed
Reduction of water consumption and wastewater discharge
