Percent Lnnd Slope: �2•� Measured Texture - derived Contour <br /> Perc Rate mound absorption ratio Loading <br /> F. Design Media Loading Rate: 1.2 GPD/ftZ Rate: <br /> G. Mound Absorption Ratio (1.F:1.6): 1.54 <i20 mpi . 1.0, 1.3, 2.0> 2.4, 2.6 si2 <br /> OR <br /> H. Design Contourlooding Rate: 12.0 GPD/ft �120 mpi � 5.0 s6 <br /> (From table i) <br /> 2. DISPERSAL MEDIA SIZING <br /> A. Calculate Required Dispersa(Media Area: Design F(ow (1.A):Design Media Loading Rate (1.F) = ftZ <br /> 750 GPD : 1.20 GPD/ft2= 625.0 ftz <br /> If a targer dispersal media <br /> area is desired, enter size: ftz <br /> B. Calculate Media Width: Contour Loading Rate (1.H)=Design Media Loading Rate (1.F) =Media Width <br /> 12.0 ft - 1.2 gpd/ftZ = 10.0 ft <br /> C. Calculate Medio Length: Dispersal Media Area (2.A):Media Width (2.6)=Media Length <br /> 625.0 ftZ : C 10.0 ft = 62.5 ft <br /> D. Select Dispersat Media: �Rock ❑Chambers <br /> ❑Other Approved Media <br /> 3• ABSORPTtON AREA SIZING <br /> Note:Mound setbacks are measured from the Absorption Area. <br /> A. Calcutate Absorption 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 stopes 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 -Medin Width =2= Width beyond Media <br /> ( ft - ft) T� = ft <br /> C. For slopes>1%, the Absorption Width is measured downhill from the upstope edge of the Media. <br /> Calculate 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.
