Basal Area Calculations:
Base Design Criteria: 360 gpd design flow,soil type 4(0.6 gpd/ft2),flat site(<5%slope)
Basal area required=daily design flow+soil loading rate
360 gpd+0.6 gpd/ft2=600 sq.ft.
Coil length=8 coils @ 5'diameter(8 x 5'=40')with 6"coil spacing 7 x 6"=3.5'=43.5'
Minimum shoulder width @ 6"(2 x 6"=1')=1'
Minimum side slopes at I : 1 slope @ 6" (2 x 6" =1')=1'
Minimum basal area length=coil length+shoulder widths+side slopes=43.5'+1'+1'=45.5'
Basal area width=required basal area+minimum basal length=600 sq.ft.a 45.5'=13.19'or 13.5'.
