Abbreviated Design Form
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, ❑ only the primary area, fly the reserve
area(check one)for Parcel A —A Division of TM 29-8K(Property ID).
Design Basis
Total length of available area: 60' Total width of available area: 80'
Estimated Pere.Rate: 55 at 36" in.(depth) Number of bedrooms(or GPD): 3

Conveyance Method : Gra_viV Distribution method (specify): Gravity

Dispersal system basis Table 5.4 LGMI required? No(Yes/No)
Effluent quality required: Primary _(Primary, Secondary,Advanced Secondary)
Square feet per bedroom: 412 Total trench bottom area required:_1236
Area Calculations
Number of trenches 7 Length of trenches: 60'
Width of trenches: 3' Center to center spacing: 9'
Reserve required?_This is the reserve_ Percent reserve area required: 100
Total width of absorption area required 57' Total trench bottom area provided: 1260
tree required width is calculated by multiplying the center-to-center spacing by one less than the number
of trenches and adding 1 french 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.
