2. SLUDGE ACCUMULATION
Sludge accumulates at the rate of 0.080 cu. ft. per year
per pound of STEADY STATE LIVE WEIGHT in swine.
Years of sludge accumulation in design? 0.0
Sludge Volume = 0.0 cubic feet
3. REQUIRED LIQUID VOLUME OF LAGOON
Design for 1.0 cu. ft. per pound SSLW
Total Volume = (SSLW * Design factor) + Sludge Volume
Total Volume = 378000.0 cubic feet
4. NORMAL LAGOON LIQUID LEVEL
Maintain normal lagoon liquid level at elevation 44.4 feet
Construct lagoon bottom elevation 38.4 feet
Lagoon size for normal lagoon liquid volume using prismodial formula

VOLUME OF LAGOON AT NORMAL LAGOON LIQUID LEVEL=34888.0 CU. FT.
VOLUME NEEDED = 378000.0 CU. FT.
THE SURFACE DIMENSIONS OF THE LAGOON AT NORMAL LIQUID LEVEL
ARE 578.0 FEET LONG BY 177.0 FEET WIDE
5. DIKE

Place spoil as a continuous dike to elevation
48.2 feet.
6. TEMPORARY STORAGE REQUIRED

Additional Drainage Area
0 square feet
TOTAL DA 119560 square feet
Pumping cycle to be 180 days.
6A.
Volume of waste produced
Volume = 378000 SSLW * 0.0101481 gallon/lb.
SSLW/day
in the pumping cycle / 7.48 gallons per cu. ft.
Volume = 92309.7 cubic feet
6B.
Volume of wash water
This is the amount of fresh water used for washing
floors or
volume fresh water used for a flush system. Flush
systems that
recycle the lagoon water are accounted for in 6A.
Volume = 0 gallons/day * 180 days in the pumping
cycle divided by 7.48 gallons per cu. ft.
Volume = 0.0 cubic feet
6C.
Volume of rainfall in excess of evaporation
Use period of time when rainfall exceeds evaporation by largest
amount.
Excess rainfall (difference) = 12.4 inches
Volume = 12.4 inches * DA / 12 inches per
foot
Volume = 123545.2 cubic feet
6D.
Volume of 25 year - 24 hour storm
Volume = 7.5 inches * DA / 12 inches per
foot
Volume = 74724.9 cubic feet
TOTAL REQUIRED TEMPORARY STORAGE
6A. 92309.7 cubic feet
6B. 0.0 cubic feet
6C. 123545.2 cubic feet
6D. 74724.9 cubic feet
TOTAL TEMPORARY STORAGE 290579.8 cubic feet
7. DEPTH OF STORAGE REQUIRED (ABOVE NORMAL LIQUID ELEVATION OF LAGOON)

Depth required = Volume of temporary storage divided by surface
area of lagoon.
Depth required =
Depth required =
290580 cu.ft. / 102306 sq. ft.
2.8 feet
Normal lagoon liquid elevation = 44.4 feet
Depth required = 2.8 feet
Freeboard = 1.0 feet
Top of Dam = 48.2 feet
THE DIMENSIONS OF THE INSIDE EDGE OF THE DAM AT ELEVATION 48.2
ARE 600.2 FEET BY 199.2 FEET

area of lagoon at normal water level.
Depth required = 215854.9 cu.ft. / 102306.0 sq. ft.
Depth required = 2.1 feet
