Width of trenches: 3' Center to center spacing: 9'
Reserve required? Yes Percent reserve area required: 100
Total width of absorption area required 39' Total trench bottom area provided: 1500
The required width is calculated by multiplying the center-to-center spacing by one less than the number
0.f_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.
