Tel 952-473-9625 Job Site; Above Address The present drainfield was determine by the City of Orono to be a failing system and has to be replaced. * See City of Orono f information for the details. The site that was tested had an average percolation rate of 11 . 1 min/in. and the depth to mottled soil was at 1 . 5-1 . 8 ft. , with standing water at 1 . 7-2. 0 ft. The current City of Orono Codes require that the minnimum depth to mottled soil and standing water musr be at 48 inches or deeper before a trench drainfield system can be installed. Therefore with the above information the only type of system that can be installed is a pressurized mound system and still be consider a standard drainfield system according th- to the current codes. The size of mound system needed for a 3 bedroom home would be the following size; Sizing Factors; PercolatiorrRate Range 46-60 min/in ( Clay Loam Soil ) Daily-Water Use; ; --450 gal/day • Land Slope; ;--2 % Overall.'Size of mound needed; ;--2952 sq. ft.

All pipes and associated fittings used for pressure distribution must be properly joined together. he pipe and connections must be able to withstand a pressure of at least 40 pounds per square inch. . The perforated pipe laterals should be connected to a 2-inch diameter 2" diameter manifold pipe and should have ends capped. The laterals should be manifold for all spaced no further than 40 inches on center and no further than 20 mounds inches from the edge of the rock. The manifold pipe should be connected to the supply pipe from the pump and should be sloped toward the supply pipe from the pump. At least 2 inches of rock should be placed over the distribution pipes. Perforated Laterals • Figure E-18 shows a layout of perforated laterals ou rovide 1pr tlure distribution of effluent over the rock layer of a g of the perforated lateral is measured from the point where the effluent enters to the end cap. All connections in the pressure distribution system must be tight in order to prevent leakage and to withstand pressure. 40 E LAYOUT OF DISTRIBUTIONTED PIPE LATERALS FOR IN MOUND PERFORATED PLASTIC PIPE -- .

Proper dosing tank construction, placement and sizing must be 4� 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 eery corrosive, so no metal parts or fittings should bk. used. The major difference between a septic tank and a dosing tank is that the dosing tank wil[ 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. ,-ire often used (see Figure E-16). • - Ensuring that the closing tank is watertight is also critical. In areas with a high seasonal or permanent water table, groundwater mai 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.
