5. DISTRIBUTION MEDIA: REGISTERED TREATMENT PRODUCTS: CHAMBERS AND EZFLOW <br /> A. Enter Dispersal Media: <br /> B. Enter the Component: Length: ft Width: ft Depth: ft <br /> C. Number of Components per Row=Bed Length divided by Component Length (Round up) <br /> oft Q ft = components/row <br /> D. Actual Bed Length =Number of Components/row X Component Length: <br /> components X ft = ft <br /> E. Number of Rows= Bed Width divided by Component Width (Round up) <br /> 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 /> X _ =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 - 1.7 ft = 1.3 ft Design Sand Lift(optional): ft <br /> B. Calculate Upslope Height: Clean Sand Lift + media depth +cover(1 ft.) = Upslope Height <br /> 1.3 1 ft 0.8 ft + 1.0 ft= 3.1 ft <br /> C.

Calculate Upstope Berm Width: Multiplier X Upstope Mound Height =Upstope Berm Width <br /> 3.33 ft X 3.1 ft = 10.0 ft <br /> E. Calculate Drop in Elevation Under Bed: Bed Width X Land Slope ; 100=Drop (ft) <br /> 10.0 ft X 7.0 % _ 100= 0.70 ft <br /> F. Calculate Downslope Mound Height: Upslope Height+ Drop in Elevation = Downslope Height <br /> 3.1 ft + 0.70 ft = 3.8 ft <br /> G.

Calculate Downstope Berm Width: Multiplier X Downstope Height =Downslope Berm Width <br /> 5.56 . x 3.8 ft = 21.0 ft <br /> I. Calculate Minimum Berm to Cover Absorption Area: Downslope Absorption Width +4 feet <br /> 16.0 ft + ft = 20.0 ft <br /> J. Design Downslope Berm =greater of 4H and 41: 21.0 ft <br /> K. Select Endstope Berm Multiplier: 3.00 (usually 3.0 or 4.0) <br /> L. Calculate Endstope Berm X Downslope Mound Height =Endslope Berm Width <br /> 3.00 ft X 3.8 ft = 12.0 ft <br /> M. Calculate Mound Width: Upslope Berm Width + Bed Width + Downslope Berm Width <br /> 10.0 1 ft + 10.0 ft + 21.0 ft = 41.0 ft <br /> N. Calculate Mound Length: Endslope Berm Width + Bed Length + Endslope Berm Width <br /> 12.0 ft + 50.0 ft + 12.0 ft = 74.0 ft <br />
