DISPERSAL MEDIA SIZING <br /> A. Calculate Required Dispersal Media Area: Design Flow (1.A) :Design Media Loading Rate (1.F)=ftZ <br /> 750 GPD: 1.20 GPD/ft2= 625.0 ft� <br /> If a larger dispersat media <br /> area is desired, enter size: 630.0 ftZ <br /> B. Calculate Medio Width: Contour Loading Rate (1.H):Design Media Loading Rate (1.F)=Medio Width <br /> 12.0 ft - 1.2 gpd/ftZ = 10.0 ft <br /> _ C. Calculate MediQ Length: Dispersa(Media Area (2.A):MediQ Width (2.B)=Media Length <br /> 630.0 ftZ : 10.0 ft = 63.0 ft <br /> D. Setect Dispersat Media: �Rock ❑Chambers <br /> ❑Other Approved Media <br /> 3. ABSORPTION AREA SIZING <br /> Note:Mound setbcicks are measured from the Absorption Area. <br /> A. Calculate Absorptron Width:Media Width (2.B)X Mound Absorption Ratio (1.D) =Absorption Width <br /> 10.0 ft X 1.5 = 15.4 ft <br /> B. For slopes from 0 to 1%, the Absorption Width is measured from the media equally in both directions. <br /> Calculate Absorption Width Beyond the Media: Absorption Width -Media Width -�2= Width beyond Media <br /> ( ft - ft) =� = ft <br /> C. For slopes>1%, the Absorption Width is measured downhill from the upslope edge of the Media. <br /> Calcutate Downs(ope Absorption Width:Absorption Width (3.A) -Media Width (2.6)=ft <br /> 15.4 ft - 10.0 ft = 5.4 ft <br /> 4.
