� ', <br /> contaminants that cause the progressive failure of conventional systems. The unit will <br /> be a 500 gal/day. A 500 gallon trash trap is installed in front of the Mutti-Flo. The unit <br /> requires to be serviced 2 times a year which will be done by Schirmers Wastewater <br /> Treatment Systems, Inc. A 2 year service & parts warranty comes with the purchase of <br /> the unit. After that time, the homeowner is required to carry a Service Contract at <br /> $100.00 a year(1999 price). A report is sent to the homeowner, city, MPCA& Multi-Flo <br /> yearly. The trash trap, Multi-Flo and pumping chamber will need to be pumped when the <br /> setable solids reach 50%. This will be determined at the time of the services. <br /> A new 1000 gallon lift station will need to be installed. <br /> A pumping chamber will need to be installed to lift the effluer�t to the treatment area. <br /> The power supply and switches must be located outside the manhole and pumping <br /> chamber in a weather proof enclosure. A waming device must be installed with a light <br /> and sound device, this is in case of a pump faiture. <br /> The manifold and suppty line pipe must have back drainage to the pumping chamber. <br /> The distribution pipes shall have their ends capped. Be sure the rock and sand fill <br /> material are clean. The sod layer below the entire mounded area must be tumed over, <br /> just break up the sod, be sure not to over work. <br /> Keep all heavy equipment off of the proposed treatment area before and after <br /> construction. The treatment area should be marked off before construction. This <br /> Design is not valid &the system wil! need to be relocated if failure to protect the areas <br /> proposed for On-Site Sewage Treatment occurs. <br /> With proper installation and maintenance, this system should have no problem in <br /> treating septic effluent effectively. <br /> Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. <br /> should be disposed of into the septic tanks. Iron filters must be diverted out of the <br /> system. Garbage disposals are not recommended, due to adding more solids &fine <br /> solids passing through to the system. Excessive amounts of soaps, anti-bacterial <br /> soaps, cleaning agents & chlorine agents may kill the bacteria needed to treat septic <br /> effluent. Additives are not recommended. Recommend to pump 8� clean your tanks <br /> through the manhole by a certified pumper every 2 years. Check with your pumper to <br /> set up a schedule. <br /> C J" _ �• <br /> Steven B.
