The owner of a Pressurized Distribution System must maintain a service contract <br /> with a licensed and certified professional to service and maintain the onsite <br /> system. A service contract must be entered into before a certificate of <br /> satisfactory completion is issued and must be maintained until the system is <br /> decommissioned. <br /> AN EFFLUENT LIFT PUMP WILL BE REQUIRED to install the septic system <br /> disposal field in the approved area and at the required depth. Detailed <br /> instructions for dosing tank/effluent pump installations are available in our office. <br /> The electrical wiring to the pump and alarm must be installed in accordance with <br /> the appropriate Electrical Code. The electrical work must be done under a Marion <br /> County Electrical Permit and must be inspected and approved by a Marion <br /> County Electrical Inspector. The work must be left uncovered and accessible for <br /> inspection. The electrical inspection includes the connections to the pump and <br /> alarm in the dosing tank, the wiring in the trench and the connections in the <br /> structure. <br /> PRESSURIZED DISTRIBUTION systems are installed in soils with excessive <br /> amounts of sand and gravel in the soil profile. Pressurized distribution systems <br /> are limited to sites with residential strength wastewater. A minimum 5-foot squirt <br /> height is required at the remotest orifice, and no more than a 10% difference in <br /> squirt height is allowed from the nearest to the remotest orifice in each line. <br /> Based on the soil texture in the test pits, the required hole spacing in the <br /> pressure distribution piping will be 24 inches on center. <br /> Specific sizing and site placement details can be found on the attached Soil <br /> Notes/Field Worksheet. <br /> Where to go from here: <br /> Please submit a detailed plot plan and materials list and an installation permit will <br /> be issued after review. A guide to pressurized distribution systems and an <br /> example schematic has been included for your convenience. <br /> This is not a permit, a permit will be issued when all required information <br /> has been submitted and approved <br /> Please contact me if you have any questions or concerns. <br /> Sincerely, <br /> Kimberlee A.
