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 /> i <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 - 1.8 ft = 1.2 ft Design Sand Lift(optional): ft <br /> B. Calculate Upslope Height: Clean Sand Lift +media depth +cover(1 ft.)=Upslope Height <br /> 1.2 ft + 1.0 ft + 1.0 ft= 3.2 ft <br /> C.

Calculate Upslope Berm Width:Multiplier X Upslope Mound Height =Upslope Berm Width <br /> 3.45 ft X 3.2 ft = 11.0 ft <br /> E. Calculate Drop in Elevation Under Bed: Bed Width X Land Slope=100=Drop (ft) <br /> 10.0 ft X 3.0 % : 100= 0.30 ft <br /> F. Calculate Downslope Mound Height: Upslope Height+Drop in Elevation =Downslope Height <br /> 3.2 ft + 0.30 ft = 3.5 ft <br /> G.

Calculate Downslope Berm Width: Multiplier X Downslope Height = Downslope Berm Width <br /> 4.54 x 3.5 ft 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: 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 3.5 ft = 11.0 ft <br /> M. Calculate Mound Width: Upslope Berm Width +Bed Width +Downslope Bene Width <br /> 11.0 ft + 10.0 ft + 20.0 ft = 41.0 ft <br /> N. Calculate Mound Length: Endstope Berm Width + Bed Length +Endstope Berm Width <br /> 11.0 J ft + 63.0 ft + 11.0 ft = 85.0 ft <br />
