Requirements including ieems not specf�caUy noted in tW�t�rlar, pRON4 CQPY KE6P THiS PLAN 68T OAI SiTB AT ALi.TiM W This on-site sewage treatment system is designed for a Type 1, five bedroom home, in �cc�rdance vNith the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. OR4N0 C43PY The soils on i:his site are a clay loam. The periodically saturated soils were located at 32" to 3�" (re�iox features). Due to the seasonally saturated soils, a Pres�urized Mound Systern will need to be installed to treat septic effluent. The bottom of the rock must be located at least 3' above the saturated soils. The soils at a depth of 12" have a percolation rate of 14.1 mpi. A pumping chamber will need to be installed to lift the 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 warning device must be installed with a light and sound d�vice, this is in case of a purnp failure. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are c�lean.. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. If the tanks have I�ss than 2' of cover, the lids, risers 8� maintenance hole covers must be insulated to a value of R10. ORONO COPY �� DR�18. l�f�tt�EAS�'�� 1R�Q1�t[�tl��. Cleanouts for each later must be installed & be accessibie from finish grade in an irrigation box with a ba{t valve. All neighboring wells are located greater than 100' away from the proposed treatment area, If a garbage dispoSal is used, an effluent screen will be needed in the 2nd tank. Keep ail 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. MANAGEMENT PIJ�NS: The tanks ne�d to be pumped every 2 years. Check with your pumper to set up a �chedule. System inspe�cted for wet areas by owner & or Inspector as d�termined by the local unit of government. Any other requirements as determined by the local unit of government With proper installation and maintenance, this system should have no problem in treating septic effl�aent effectively. Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. shou{d be di�°,posed of into the septic tanks. Recommend Iron filters be diverted out of the system. �ecommend to divert the water sof�ner also if the iron filter is diverted. Garbage disposal� are not recommended, due to adding more solids &fine solids passing throi�gh ta the system. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower cleaners used every shower & chlor�ine agents may kill the bacteria ne�ded to treat septic effluent. Additives are not recommended. Recommend lauridering b�� limified to 3 to 4 loads per day. Steven B.
