The Presby Enviro-Septic system design selected handles the 1,720 gpd design flow from the 16-unit motel. The system includes two, 1,500-gallon septic tanks with a Presby Maze installed in one tank to increase efficiency by lengthening the flow path and further trap suspended solids. During ground preparation for the replacement system, three-feet of silty clay on top of the old system that was contributing to the perched water table was removed. The new system was installed in two phases. Approximately two feet of clean sandy loam fill was placed below the proposed disposal system and once the first section of the system was installed and inspected, the existing disposal system was disconnected. Then, the new 1,500-gallon septic tank with the Presby Maze and a new septic tank and pump station were installed and connected to the replacement disposal system. Once complete and functional, the second section of the system was completed, connected, loamed, and seeded as required by code.
