a . t : � The soils at a depth of 12" have a percolation rate of 4.5 mpi. The existing tanks may be used if water tight and upon approvat from the local Inspector. A 6BR home requires 1-1250 & 1-1000 by the city of Orono. The existing tanks may be 2-1000 gallon capacity which wilt require another tank to be installed. 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 manhote 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. The existing weil on this site is 55' from the At-Grade System and 50' from the absoprtion area of the down slope toe of the future mound system wMich will require city approval. City oode is 75'. All other neighboring wells are greater than 100' away from the proposed treatment areas. Keep all heavy equipment off of the proposed treatment area before and af�er construction. The treatment ar�ea should be marked off bef�one constrvction. 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 human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tanks. Iron filters must be diverted out of the system. Garbage disposals are not recommended, due to adding more solids 8 fine solids passing through to the system. Exoessive amounts of soaps, anti-bacterial 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 certifted pumper every 2 years. Check with your pumper to set up a schedule. ��'�-�• C-�� Steven B. Schirmers 2
