5. Dralnfleld Rock Needed.
66.7 cubic yurda of rock la needed to have 12 Inches under
and 2 Inches over a 4 inch distribution pifc.
6. Septic Tanks.
2 tanks each of ut least 1000 gallons are needed along with*
a third pumping tank .uid a pump in order to deliver the ef
fluent to tije higher drainfield ..rca, An ..lurm device should
also be used to warn of any pump failure.
7*. Additional Information.
Since the druinfield area is on a higher area, probably no
extra measures are necessary in order to •divert runoff wat
er from the site. Another area equal in size to the prop
osed drainfield area must be left undisturbed in order to
alternate site should it ever be heeded for additional trenches. *
