Avoid the area where the test hole was dug, it has been overly excavated and disturbed. There are many fruit trees in this area, some will need to be cut down and the stumps removed during the install process. Pressurized distribution systems are especially susceptible to root damage. Specific sizing and site placement details can be found on the attached Soil Notes Form, and Onsite Inspection Map The owner of a Pressurized Distribution System must maintain a service contract with a licensed and certified professional to service and maintain the onsite system. A service contract must be entered into before a certificate of satisfactory completion is issued and must be maintained until the system is decommissioned. 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. PRESSURIZED DISTRIBUTION systems are installed in soils with excessive amounts of sand and gravel in the soil profile. Pressurized distribution systems are limited to sites with residential strength wastewater. A minimum 5-foot squirt height is required at the remotest orifice, and no more than a 10% difference in squirt height is allowed from the nearest to the remotest orifice in each line. Based on the soil texture in the test pits, the required hole spacing in the pressure distribution piping will be 24 inches on center. This is not a permit, a permit will be issued when all required information has been submitted and approved Please contact me if you have any questions or concerns.
