The conditions observed during this site evaluation indicate that the area around the evaluated test holes is NOT CAPABLE of supporting a STANDARD SEPTIC SYSTEM due to high shrink swell soils and a high temporary water table. Under these conditions,a SAND FILTER SYSTEM is required by Department of Environmental Quality(DEQ)rules. Please refer to the signed approved site plan dated September 26,2005. This property is approved for the installation of a SAND FILTER septic system in the area of the approved test holes. Sand filter systems are installed where soil,drainage,or space limitations do not allow for a standard system installation.The sand filter unit pre-treats the septic tank effluent before it is - discharged into the ground.Detailed plans are required for the sand filter system prior to the issuance of the sand filter permit. See the attached"Sand Filter System Requirements for Plans".Two sets of plans for the system must be submitted at the time of application for the installation permit. AN EFFLUENT LIFT PUMP WILL BE REQUIRED to install the septic system disposal field in the approved area and at the required depth.Detailed instructions for dosing tank/effluent pump installations are available in our office.The electrical wiring to the pump and alarm must be installed in accordance with the appropriate Electrical Code.The electrical work must be done under a Marion County Electrical Permit and must be inspected and approved by a Marion County Electrical Inspector.The work must be left uncovered and accessible for inspection. The electrical inspection includes the connections to the pump and alarm in the dosing tank,the wiring in the trench and the connections in the structure.
