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, G3-only the reserve
area (check one) for Tax Map 55-26A 0 392 Blair Park Ridgy
Design Basis
Total length of available area: 65' Total width of available area: 30'
Estimated Pere. Rate: 65 at 24" in. (depth) Number of bedrooms (or GPD): 3
2
Conveyance Method : Pump Distribution method (specify): Pump
3c
Dispersal system basis AOSS regs LGMI required? No (Yes/No)
Effluent quality required: Advanced Secondary (TL 3) (Primary, Secondary, Advanced Secondary)
Square feet per bedroom: 183
LPD/trench
Linear Loading rate — 0.82 ag I/day/so.ft.
Area Calculations
Number of trenches 3
Width of trenches: 3'
Reserve required? this is reserve
Total width of absorption area required 23'
Total trench bottom area required: 549
Length of trenches: 65'
Center to center spacing: 10,
Percent reserve area required: 100
Total trench bottom area provided: 585
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.
* Butterfly trenches — 20' width required
