No 627 - State License #394 - Phone 763-497-3566 - Fax 763.497-5011 www.sptesting.wastewater(-@comcast.net- schirmerswastewater.com June 3, 2024 Brian O'Connell -- Lynne Rasmussen 1285 French Creek Dr. Orono, MN A Compliance inspection was completed for the existing on-site sewage treatment system located on this property for the sale of the home. The system consists of a Type IV, Performance system with 1 - 1000 gallon trash trap tank, 1-1000 gallon pump tank (pump #1) pumping 15.6 gallons every 30 minutes to a 1000 gallon Multi - Flo Unit then flowing to another 1000 gallon pump tank (pump #2) that pumps to a 1200sq.ft. trench system. The Multi -Flo was added to the existing system in 2003 to rehab the existing trenches that were hydraulically overloaded. Soil probing in to the trench system found no ponding or hydraulic overloading on 5-23-24. Soil borings into the system found the bottom of the rock at 42" below existing grade. 10" to 12" of fill soil was found between the trenches. This leaves the bottom of the trenches at 30" to 32" below the original soil. Soil boring #1 found mottled soil (redox features) at 70" below grade & the bottom of the trench at 32" below grade leaving a 38" separation. Soil boring #2 found mottled soil at fib" below original grade & the bottom of the trench at 32" below grade leaving a 36" separation from the bottom of the rock & redox features. This system meets the required separation as designed & is classified as in compliance with Minnesota Chapter 7080 rules. Annual monitoring of the seepage bed has found no hydraulic overloading or ponding. The Multi -Flo has been serviced by Schirmers Wastewater Treatment Systems since it was installed. Monitoring of the trenches have found the trenches dry. No indication of hydraulic overloading. The Multi -Flo Unit requires to be serviced 2 times a year at a cost of $275.00 a year (2024 price). The trenches have to be monitored 1 time a year at a cost of $50.00 a year (2024 price). These prices are subject to change.
