' 5. DISTRIBUTION MEDIA: REGISTERED TREATMENT PRODUCTS: CHAMBERS AND EZFLOW <br /> A. Enter Dispersal Media: <br /> B. Enter the Component Length: ft Enter the Component Width: ft <br /> C. Number of Components per Row= Bed Length divided by Component Length (Round up) <br /> ft : 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 an 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 - 2.2 ft = 1.0 ft Design Sand Lift (optional): ft <br /> B. Calculate Upslope Height: Clean Sand Lift + media depth + cover(1 ft.) = Upslope Height <br /> 1.0 ft + 1.0 ft + 1.0 ft = 3.0 ft <br /> C.

Calculate Upslope Berm Width: Multiplier X Upslope Mound Height = Upslope Berm Width <br /> 3.85 ft X 3.0 ft = 11.6 ft <br /> E. Calculate Drop in Elevation Under Bed: Bed Width X Land Slope : 100 = Drop (ft) <br /> 10.0 ft X 6.0 % : 100 = 0.60 ft <br /> F. Calculate Downslope Mound Height: Upslope Height + Drop in Elevation = Downslope Height <br /> 3.0 ft + 0.60 ft = 3.6 ft <br /> G.

Calculate Downslope Berm Width: Multiplier X Downslope Height = Downslope Berm Width <br /> 5.26 x 3.6 ft = 18.9 ft <br /> I. Calculate Minimum Berm to Cover Absorption Area: Downslope Absorption Width + 4 feet <br /> 16.0 ft + 4 ft = 20.0 ft <br /> J. Design Downslope Berm =greater of 4H and 41: 20.0 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 3.6 ft = 10.8 ft <br /> M. Calculate Mound Width: Upslope Berm Width + Bed Width + Downslope Berm Width <br /> 11.6 ft + 10.0 ft + 20.0 ft = 41.6 ft <br /> N. Calculate Mound Length: Endslope Berm Width + Bed Length + Endslope Berm Width <br /> 10.8 ft + 63.0 ft + 10.8 ft = 84.6 ft <br />
