(Refer to Table VI) LONG TERM APPLICATION (R_a)
*GALLONS PER ABSORPTIVE AREA (SF) PER DAY

Ib 0.38
II 0.25
III 0.20
IV 0.1

The absorptive area consists of the bottom area of the excavation PLUS one foot of sidewall area around the full perimeter of the excavation.

The required absorptive area shall be calculated by the following formula:

ABSORPTIVE AREA = Q/R_a, Where Q is the wastewater usage rate in gallons per day (see Table III, Relating to Wastewater Usage Rate).
