D. ROCK LAYER DIMENSIONS
1. Multiply average design flow(A)by 0.83 to obtain required area of rock tayer.Item A x 0.83=
375 �d x 0.83 f1�/c�d= 320 ft2
2. Determine rock layer width =0.83 fY`lgpd x Linear Loading Rate(LLR)(see LLR chart)

320.0 X 1_0 ft= 320.0 ft3
2. Divide ft3 by 27 ft3/yd3 to get cubic yards
320_0 ft3 / 27 = 11.9 yd3
3. Multiply cubic yards by 1.4 to get weight of rock in tons;
11.9 yd3 X 1.4 tordyd3 = 16.6 tons

G. MOUND SLOPE WIDTH 8�LENGTH(Greater than 1%)
1. Downslope absaption width=absorption width minus rock layer width

2. Cakulate gallons per inch
There are 7.5 gallons per cubic foot of volume,therefore muitipiy the area(1 A,B or C)
times the conversion fador and divide by 12 inches per foot to calculate gallon per inch.
Surface area x 7.5112= 0 tl� x 7.5 1 12inlft = 2p.0 gallon per inch Legal Tank:

3. Caiculate totallank volume 100°k the dai{y flow
A. Depth from bottom of inlet pipe to tank bottom = �;n or Alternating Pumps
B. Total tank volume=depth from bottom of inlet pipe to tank bottom(3A)x gaVin(2)
= 50 in x 20.0 gaVin = 1000.0 gallons
4. Calculate gallons to cover pump(with 2-3 inches of water covering pump)
(Pump and blodc height+2 inches)x gailon per inch
