The current drainfield system was determine to be a failing system according to the current City of Orono Codes. * See the City of Orono records for the details. ORONO Copy A site was tested in the front yard area to determine what type of drainfield could be installed and still comply with the current codes. In the arca that was tested the average percolation rate was 39. 1 min/in. and the depth to mottled soil was at 1 . 8-2. 0 ft. ( 21 -24 inches. Wh-- * Mottled soil is consider the high seasonal saturated soil level that exist during the wet seasons (Spring and Fall ) . The current Orono codes state that when mottled soil is encounter between 12-42 inches then an above ground pressurize mound must be installed, therefore with the above information the only system that can be installed in this area is a pressurized mound system, this system is consider to be a standard system. The size of system needed for a 6 bedroom home would be the following size; Sizing Factors; Daily water use; ; --900 gal/day Perc. Rate Range 46-60 min/in.

Note the upslope can be located on the Soil boring # 1 area due to the fact that the effluent will flow donslope due to the 4 5 slope. However the rock bed area must be located in the S. B. # 2, 3 and 6 area due to the fact that this area is original soil and no fill material was encounter. Soil boring also were done at a lower area of this lot ( SB # 4 & 5 ) these boring indicate mottled soil at 7 and 8 inches with standing water at 11 and 8 inches If a mound system would be located in this area it would be consider to be an OTHER SYSTEM AND WOULD REQUIRE TO BE MONITOR. it Evaluator 11-1-�Wu Robert A.

Proper dosing tank construction, placement and sizing must be considered to ensure reliable system operation. The dosing tank construction requirements are the same as for sewage tanks. The tank must be durable and watertight and must withstand the soil loads, which tend to push in on the walls. The environment in the tanks is very corrosive, so no metal parts or fittings should be used. The major difference between a septic tank and a dosing tank is that the dosing tank will be emptied on a daily basis. Since the tank will be emptied every day, anchoring it against flotation is critical in areas with a high seasonal or permanent water table, where mound systems, which require pressure distribution, are often used (see Figure E-16). Ensuring that the dosing tank is watertight is also critical. In areas with a high seasonal or permanent water table, groundwater may leak into the dosing tank and overload the system. The seals around the pipes that enter and exit the dosing tank are especially vulnerable to leaks. If the pump is running more than the few minutes a day it takes to pump out the accumulated septic tank effluent, groundwater may be leaking into the septic tank or dosing tank. N Ito 1, cr .
