Abbreviated Design Form Page 5 of 5
This form is for use with gravity,pump to gravity,enhanced flow,and low pressure distribution(LPD)sewage system designs and
when applying for a certification letter or subdivision approval.
This abbreviated design covers the primary and reserve area for TM 130-35A,Hilton Patterson
Design Basis
Total length of available area: 75 Total width of available area: 67
Estimated Perc.Rate 70 at 18 in.(depth) Number of bedrooms 3
Conveyance Method: Pump Distribution method(specify): D-Box
Dispersal system basis Table 1 AOSS Regs. LGMI required? No
Effluent quality required: Primary-TL-3 Reserve-TL-3
Square feet per bedroom: 300 Total trench bottom area required: 900
Square feet per bedroom reserve 300 Total area for reserve 900
Area Calculations
Number of trenches 4 (Note if a pad is used) Length of pad or trenches: 75
Width of pad or trenches: 3 Center to center spacing: 9
Reserve required? Yes Percent reserve area required: 100%
Total width of absorption area required 67 Total trench bottom area provided: 900
4 Ditches 75' Long Reserve
The required width is calculated by multiplying the center-to-center spacing by one less than the number of
trenches and adding 1 trench width plus any required reserve area. If the topography is not uniform across the
length of the site the trenches will need to flare apart on one end to maintain contour. When this occurs it is
necessary to use a center-to-center spacing that accounts for the flair or the installer will not be able to fit the
system within the approved area. It is perfectly acceptable to have more area available, especially up and
down the slope, than is required.
