Legal Description 210 Big Island; Lake Minnetonka; City of Orono; Hennepin County ' B. Site Conditions The property is located on an island of Lake Minnetonka. From the lake the property slopes up a � 10%— 12%incline with mature maple and oak trees. C. Soil Conditions ! t The Hennepin County soil survey mapped the azea as the Lester Series. The Lester Series is the j Minnesota state soil and is very common in Des Moines Lobe glacial till deposits of central ! Minnesota, specifically Wright and Hennepin Counties. j � The soil survey indicates the soils in the Lester Series are very deep, well drained loamy soils � formed in glacial till. Six soil borings were completed in the general area of the proposed and � alternate drain field areas, see Fig. 1. i I The results of the soil borings indicate that the potential for seasonal saturation exists at 31-34" i below the surface in the azea investigated. This is evidenced by the presence of distinct I redoximorphic features. Redoximorphic features in a higher landscape position such as this are i likely the result of a stalled wetting front within the fine texture soils and will likely only occur I sporadically; however the site cannot support a standard subsurface drain field without achieving ' additional vertical separation distance reductions prior to dispersal. Percolation tests completed indicates the underlying soil has an average percolation rate of 7.5 minutes per inch at the depths tested. � D. Selection and Sizing of Treatment Svstem ' The existing residence is a small two bedroom seasonal cabin without a well. To accommodate ' possible future construction the Onsite Wastewater System (OWS) will be designed to accommodate 1 a three bedroom, Type II single family dwelling with an estimated daily flow from the residence of 300 gallons per day. To allow for the shallow subsurface drain field with a vertical separation distance of I foot from the bottom of the drain field trenches to redoximorphic features, peat filters with a 2 foot depth will need to be installed to pre-treat the effluent prior to drain field dispersal. This type of system is commonly referred to as a "2 + 1" and is allowed in Minnesota Rules Chapter 7080 as an Other System. E. Description of Treatment Process • Primary Treatment - Sewage is gravity discharged from the house to a septic tank. Natural biological activities taking place inside of the septic tank will separate solids and suspended particles. Solids are reduced to some extent through this process. • Secondary Treatment — Effluent from the septic tank gravity flows into the pumping chamber. Effluent is pumped to a distribution manifold in the Puraflo Peat Biofilter on a timed basis. Effluent percolates down through the peat media and drains out the bottom of the filter pod. The treated effluent flows out of the filter pod to the pumping chamber directed to the drain field. Anticipated treatment levels are expected to exceed a 90% reduction of BOD, TSS, total coliforms, and pathogens. • Final Treatment — Effluent is directed to a new 204 square foot drain field. As the effluent trickles down into the soil biochemical processes remove the few remaining viruses and bacteria. F. Descriudon of Treatment Svstem (See figures, design sheets, and manufacturer sheets for additional detail.) • Septic Tank — (1) 1,500 gallon fiberglass septic tank. Install septic tank per manufacturer's recommendations. • Pump Tank — 1,000 gallon two comparhnent fiberglass septic tank, two 500 gallon compartments. T'he first compartment will contain an efIluent that will deliver effluent on a timed basis to the peat filter pods. The second compartment will contain an efIIuent pump that will dischazge to the first drop box in the drain field on a demand basis. Install septic tank per manufacturer's recommendations. • Septic Tank Risers — 24" diameter heavy corrugated PVC pipe. A watertight seal must be created between top of tank and the each riser. • Septic Tank Riser Cover — 24" diameter fiberglass cover with gasket. Tank riser covers should include insulation. Do not bury riser cover. • Pumps — Effluent pump to be selected to deliver a minimum of 20 gallons per minute with 20 feet of head to the peat filters. Effluent pump to be selected to deliver a minimum of 10 gallons per 2 � � � � ; ; minute with 30 feet of head to the drain field. The control panel selected should be capable of controlling both pumps with alarms. • Peat Filer—(2) Puraflo Peat Biofilter pods. Install according to manufacturer's detail. • Drain Field—Excavate the drain field trenches as depicted on Figure 2 when the soil is less than the plastic limit to prevent smearing and compacting. Installer is responsible for determining if the soil is below the plastic limit prior to excavation. Depth of excavation shall be to the elevations given on Figure 2, scarified and leveled. Place Quick4 High Capacity Infiltrator Gravelless Chambers in the trench bottom connected by gravity drop boxes. • Grading - Back fill with native soil, seed for cover, and mulch for erosion control ASAP after installation. Create positive drainage away from the septic tank and drain field, allow for soil settling. Do not allow channeled runoff over the drain field; create drainage swales along the outer edges of the drain field to prevent excess runoff on the drain field. G. Maintenance and Monitoring Requirements The owners of the system must be aware that site constraints have prompted the installation of an Other System. State and Local codes require Other Systems to have maintenance and monitoring agreements and mitigation plans to be in effect for the life of the system (see Appendix B and C for the Maintenance and Monitoring Plan, and Mitigation Plan for details). The owner will need to contract with a licensed service provider to provide the maintenance and monitoring of the system H. Limitations Our investigation, layout, design, and recommendations aze based on data submitted. If conditions considerably different from those described in this report are encountered, we must be notified. If proposed construction is changed, we must be norified to evaluate the effect of the changes on the wastewater system. Any changes to the design must be approved by the designer and will be assessed additional design costs. If changes are made to the design without the knowledge and approval of the designer the design shall be void. All construction is to be in accordance with the ISTS regulations. Pipe type and size, installation requirements, sepdc tank construction, and other specifications not depicted in our report are to conform to ISTS regulations. The installer of the ! system is to be licensed by the Minnesota Pollution Control Agency. I certify that this plan, document or report was prepared by me or under my direct supervision and that I am a duly licensed Professional Soil Scientist and Designer 1 under the laws of the State of Minnesota.

The system will consist of 1,500 gallons sepric tank capacity, two 500 gallon pumping charnbers, two Puraflo Peat Biolfilter units, and a 204 square foot drain field with 17 Quick4 Infiltrator High Capacity chambers. O�eration Description: Septic tank effluent will be dischazged out of the pumping chamber to the peat filters. A control panel will dose the filter on a timed basis via a lateral network, distributing the septic tank effluent evenly over the filter where 80-90% of necessary treatment will take place. An under drain in the peat filters will drain the filter effluent to the second pump chamber with a second pump to the drain field on a demand basis. A gravity fed drop box system will distribute the filter effluent into shallow drain field trenches.
