r � Due to the system being sized for 1.27sq.ft. (perc rate 10.4) low water use facilities wiil need to be installed in all three properties. If water softners are used, they must be diverted either to the ground surface (not the lake) or install approximately 50 lin.ft. of gravelless trench. The new tanks may be plastic but must be heavy duty due to the high water table, see the site plan for the location. A pumping chamber will need to be installed to lift the septic effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A waming device must be installed with a light and sound device, this is in case of a pump failure. An exterior device will need to be installed. All neighboring wells are located greater than 100' away from the proposed treatment area and 50' away on this site (deep well). Approval will be needed to be 50' away from a well with a tank at the Robb cabin. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid & the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than gray water (laundry, showers, etc.) should be disposed of into the septic tanks. Garbage disposals are not recommended, due to adding more solids & fine solids passing through to the system. Excessive amounts of soaps, cleaning agents & chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend to pump & clean your tanks through the manhole by a certified pumper every 2 years. Check with your pumper to set up a schedule. � n �� ,� Steven B. Schirmers 2
