System Design
1 • Percolation Hate. Tvr.e of System.
1.75 minutes rer inch. Stanaerd System.
Pporosed Plow Rate.
75C a.P.D.
3. Soil Treatment Areci Required.
0.03 percolation factor x 75^ G.P.D. is 6A‘^ So. Ft. minimum.
4. Size and Fumber of trenches.
4 trenenes 65 feet lon£^ x 3 feet wide is 76C So. Ft. These
trenches i%culd be rc.-.ced 7,5 feet apart center to center,
ind be L-3 feet deep in tne iij-tiral soil.
5. Drainficid rock Heoili-ecJ.
43.5 cubic yds. of rock is needed to have Ic inches jnder
end e. Inches ever a )+ inch distribution pipe.
6. Septic Trunks.
2 seotic tanks each of 1000 g-allons are recominendcd. In ada-
Itlcn, a third pumping tank with a pumr or else a pumping
ccmpartirient in the second tank is needed to reach the higher
drainfield area. Another ootlon is to run gravity from the
first floor end use an e;5ector pump from the basement bath-
roo:r.s.
7. Additional Information.
Since the drinfield arte is rartly in an area thj-.t v.'-s not
tested, if soils ether than sand are encountered, then i'.tre
drainfield area will be needed.
Sincerely,
FERCCR, INC.
