?°(.7 <br /> 1TPEST111G, <br /> INC. Steven B. Schirmers — MPCA Cert. No. 627 <br /> 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 <br /> September 15 , 1993 <br /> Jeff Martineau <br /> 480 Orchard Park Rd. <br /> Orono, Henn. Co. , MN <br /> This site has an existing failing On-Site Sewage Treatment System <br /> . with effluent surface discharging. This site has very limited <br /> space for a new treatment system. Soil Borings indicate mottled <br /> soil at 36" to 38" below the ground surface . Due to the seasonally <br /> high water table (mottled soil ) this site would require a Pressurized <br /> Mound System. There is no area available for a mound . With the <br /> mottled soil at 36" below the ground surface, an At Grade System <br /> could be installed which is classified as an alternative system. <br /> Due to this site being very limited, an at grade system with a <br /> loading factor at 4gpd/sq.ft. would be adequate for only 172 <br /> gal/day. By using pretreatment, the loading factor is 6gpd/sq.ft, <br /> the area available would be adequate for 256 gal/day. A normal <br /> 2BR home is Designed for 300 gal/day. Low water use facilities k' <br /> would need to be installed, 1.5 gal .flush toilets , low flow <br /> shower heads , water softner with recharge tank with no discharge <br /> etc. to reduce the water use. An Alternative system will require <br /> a variance from the City of Orono. The Multi-Flo Waste Water <br /> Aerobic Treatment System is an NSF approved Class 1 aerobic <br /> system. The system requires to be serviced 2 times a year which <br /> will be done by Schirmers Wastewater Treatment System, Inc. A <br /> 2 year service contract comes with the purchase of the unit. After <br /> the 2 year period, the homeowner is required to carry a service <br /> ; ,contract at a cost of $100 .00yr. (1993. price) . A report will be <br /> ' sent to the City, MPCA, Multi-Flo & the homeowner. .The Multi-Flo <br /> unit will be model F+B 0 . 5 , 500 gal/day. This system treats the <br /> • <br /> BOD & TSS with a removal of 96% to .98%&.._virus removal is greater <br /> than 99% . To install the Multi-Flo unit, a 500 gallon septic tank • <br /> 'twill need to be installed as- a trash trap ahead of the unit. <br /> • The pumping chamber will be a 1500 gallon capacity to allow for <br /> '' additional reserve storage if needed. 'A water meter will need to <br /> be installed to monitor daily water use. If the water use exceeds. <br /> 256 gal/day, the effluent will need'to.be-i'delivered by ,a.-timeri <br /> '. 4fonly•allowing 256 gal/day. A high water alarm would signal to the <br /> homeowner to conserve on water or have the reserve storage pumped <br /> & hauled off site . <br /> • CONT' D <br /> t Lo D <br /> RU <br />
