4. DISTRIBUTION MEDIA: ROCK A. Rock Media Depth Below Distribution Pipe E= in E= ft 5. DISTRIBUTION MEDIA: REGISTERED TREATMENT PRODUCTS: CHAMBERS AND EZFLOW A. Enter Dispersal Media: Arc 36 Low Profile (LP) or equivalent B. Enter the Component: Length: ft Width: 2.83 ft Depth: 0.67 ft C. Number of Components per Row = Bed Length divided by Component Length (Round up) 30 ft : ft = components/row D. Actual Bed Length = Number of Components/ row X Component Length: components X 5.0 ft = 30.0 ft E. Number of Rows = Bed Width divided by Component Width 1fl ft : ft = 3.5 rows Adjust width so this is an whole number. F. Total Number of Components = Number of Components per Row X Number of Rows X E::E::1 = 21 components 6. MOUND SIZING A. Calculate Clean Sand Lift: 3 feet minus Depth to Limiting Condition = Clean Sand Lift (1 ft minimum) 3.0 ft - 1.0 ft = 2.0 ft Design Sand Lift (optional): none ft B. Upslope Mound Height = Clean Sand Lift + Depth of Media + Depth of Cover (1 ft) 2,0 ft + 1.17 ft + 1.0 ft = 4.2 ft C. Berm Width = Upslope Mound Height (4.13) X 4 (4 is recommended, but could be 3-12) 4,2 ft X 0.2 ft = 0,8 ft D. Total Landscape Width = Berm Width + Dispersal Bed Width + Berm Width 0,8 ft + 10.0 ft + 0.8 ft = 11.7 ft E. Additional Berm Width necessary for absorption - Absorption Width - Total Landscape Width 15.0 ft - 11.7 ft = 3.33 ft if number is negative (<0), value is ZERO F. Final Berm Width = Additional Berm Width + Berm Width 3.33 ft + 0.8 ft = 4.2 ft G. Total Mound Width = Final Berm Width + Dispersal Bed Width + Final Berm Width 4.2 ft + 10.0 ft + 4.2 ft = 18.3 ft H. Total Mound Length = Final Berm Width + Dispersal Bed Length + Final Berm Width 4,2 ft + 30.0 ft + 4.2 ft = 38.3 ft I. Setbacks from the Bed: Absorption Width - Dispersal Bed Width divided by 2 ( 15.4 ft - 10.0 ) / 2 = 2.5 ft
