5. DISTRIBUTION MEDIA: REGISTERED TREATMENT PRODUCTS: CHAMBERS AND EZFLOW <br /> A. Enter Dispersal Media: <br /> B. Enter the Component: Length: I ft Width:I ft Depth: !ft <br /> C. Number of Components per Row= Bed Length divided by Component Length (Rouno up) <br /> ft _ ft = components/row <br /> D. Actual Bed Length = Number of Components/row X Component Length: <br /> It components X 1 ft = ft <br /> E. Number of Rows =Bed Width divided by Component Width (Round up) <br /> 1 ft; ft = rows Adjust width so this is on whole number. <br /> F. Total Number of Components=Number of Components per Row X Number of Rows <br /> IX = components <br /> 6. MOUND SIZING <br /> A. Calculate Minimum Clean Sand Lift:3 feet minus Depth to Limiting Condition = Clean Sand Lift <br /> 3.0 ft • 1.0 ft = 2.0 ft Design Sand Lift (optional): ft <br /> B. Calculate Upstope Height: Clean Sand Lift > media depth *cover(1 ft.) = Upslope Height <br /> 2.0 ft - 0.8 ft -t 1.0 ft= 3.8 ft <br /> C.

Calculate Upslope Berm Width: Multiplier X Upslope Mound Height =Upslope Berm Width <br /> 2.62 )ft X 3.8 ft = 9.8 ft <br /> E. Calculate Drop in Elevation Under Bed: Bed Width X Land Slope = 100= Drop(ft) <br /> 10.0 ft X 13.0 % : 100= 1.30 ft <br /> F. Calculate Downslope Mound Height: Upslope Height Drop in Elevation = Downslope Height <br /> 3.8 ft - 1.30 ft = 5.1 ft <br /> G.

Calculate Downslope Berm Width: Multiplier X Downslope Height =Downslope Berm Width <br /> 4.95 x 1 5.1 I ft = 25.0 ft <br /> I. Calculate Minimum Berm to Cover Absorption Area: Downslope Absorption Width - 4 feet <br /> 16.0 I ft 4 ft = 20.0 ft <br /> J. Design Downslope Berm = greater of 4H and 41: 25.0 ft <br /> K. Select Endslope Berm Multiplier: 3.00 (usually 3.0 or 4.0) <br /> L. Calculate Endslope Berm X Downslope Mound Height = Endslope Berm Width <br /> 3.00 ft X 5.1 ft =I 15.2 1ft <br /> M. Calculate Mound Width: Upslope Berm Width - Bed Width Downslope Berm Width <br /> 9.8 I ft - 10.0 ft * 25.0 ft = 44.8 ft <br /> N. Calculate Mound Length: Endslope Berm Width - Bed Length Endslope Berm Width <br /> I15.2 ft - 63.0 ft - 15.2 ft =1 93,3 Ift <br />
