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 />ft - ft = components/row <br />D. Actual Bed Length = Number of Components/ row X Component Length: <br />=components X =ft = C�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 />C ------J 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 - = ft = 2.0 ft Design Sand Lift (optional): =ft <br />B. Calculate Upslope Height: Clean Sand Lift + media depth + cover (1 ft.) = Upslope Height <br />2.0 ft + 0.5 ft + = ft = 3.5 ft <br />C.

Calculate Upslope Berm Width: Multiplier X Upslope Mound Height = Upslope Berm Width <br />3.57 ft X 3.5 ft = 12.0 ft <br />E. Calculate Drop in Elevation Under Bed: Bed Width X Land Slope - 100 = Drop (ft) <br />10.0 ft X L 4.0 % - 100 = 0.40 ft <br />F. Calculate Downslope Mound Height: Upslope Height + Drop in Elevation = Downslope Height <br />3.5 ft + 0.40 ft = 3.9 ft <br />G.

Calculate Downslope Berm Width: Multiplier X Downslope Height = Downslope Berm Width <br />4.76 x 3.9 ft = =ft <br />I. Calculate Minimum Berm to Cover Absorption Area: Downslope Absorption Width + 4 feet <br />16.0 ft + = ft = [=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 Endstope Berm X Downslope Mound Height = Endslope Berm Width <br />3.00 ft X 3.9 ft = =ft <br />M. Calculate Mound Width: Upslope Berm Width + Bed Width + Downslope Berm Width <br />12.0 ft + =ft + 20.0 ft =42.0 ft <br />N. Calculate Mound Length: Endslope Berm Width + Bed Length + Endslope Berm Width <br />12.0 ft + = ft + = ft = =ft <br />
