SITS EWAi UATION REPORT
FOR DM(NIS F. KUMLIN IN
LOT 20 BLOCK 10 FO)CdOOD
November 9, 1978
As requested, and according to the city of Orono regulations,
six percolation tests and three soil borings were taken on Nov-
ember 6-8, 1978.
Percolation ho:tes were dug to a depth of 42 inches being 6
inches in diameter. The soil borings wero 3 inch diameter holes
to an 8 foot depth. b_ Dayton model 22014C auger and a hand auger
were used to dig the holes.
The avorage percolation rate for the 6 holes was 41.3 minutes
per inch. The soil was more suitable for a drainfield in the area
of holes 1-3 as wall as the ground water conditions there. Holes
4-6 were approaching a small drainage swa'e, and thus contained
some heavier soils and a higher water table. The propomed area
for a standard drainfield system is shown on the attached drawing.
The field should be kept as far to the east as possible and up the
hill as far as possible. There is an area up to 25 feet east of
holes 1-2 which can be utilized. Any area farther to the east
yields a grade greater than the allowable 12%. Installation of
such a system must adhere to the requirements of the Orono on -site
:Wage -treatment manual.
Sinrgrely,

The average percolation rate for the six ho1e3 was 41.3 !:in-
utes per inch. r'or the proposed four bodroon house, 1200 squnre
feet of drainfield trea is required.
Because of the poorer soil : o the west, it is that
trenches ')e f-J f,-� 3t in Length and kept to the east as far a: poss-
ible. Fiva trenches of three feet in width would yield the rea-
uired 1 OJ ,;uarc feet of drainfiold apes. lith a ninimum spacing
of 7.'-, feet center to •enter the total width would be thirty feet.
•i nce there is not a greR t einount of fall from the top of the
hill to th-. -?reinfl old .area, it apr oars a pump will be required to
serve the basement bathrooms should a full death basement be con-
structec. Thus, it r p=p is naeued, thi drain'_'; eld trenches should
bo kert i� tho hi' 1 towr rd th.- house as 1'ar as oossible.
:'.ao 10:0 gallon septic tanks are reconxinnded for tho rouse. In
actditi )n, a 7" gallon p .mpiniz tank will be needed if an effluent
ou. is used. Another alternrttive is to `.n^tall an ejector purr in
the :lasemon' 411 ,!hich car the pum-,ing tank is not reouir3.'.
