Mound System Design Example

Step 15. Overall Mound System Length and Width.

Overall Length = (Distribution area length) + (2)*(End slope length)

Overall Width = (Distribution area width) + (Upslope width) + (Downslope width)

Overall Length and Width:

Overall Length	= (Distribution area length) + (2)*(End slope length)
	= (90 ft) + (2)*(11.5 ft)
	= 113 ft
Overall Width	= (Distribution area width) + (Upslope width) + (Downslope width)
	= (4 ft) + (6.7 5 ft) + (16.75 ft)
	= 27.5 ft

The overall dimensions of this mound system (27.5 ft * 113 ft) fit within the proposed site area (50 ft * 160 ft).
