DISPERSAL MEDIA SIZING <br />A.Calculate Dispersal Bed Area: Design Flow ÷ Design Media Loading Rate <br />GPD/ft2 =ft2 <br />ft2 <br />B.Enter Dispersal Bed Width: ft Can not exceed 10 feet <br />C.Calculate Contour Loading Rate: Bed Width X Design Media Loading Rate <br />ft2 X GPD/ft <br />2 =gal/ft Can not exceed Table 1 <br />D.Calculate Minimum Dispersal Bed Length: Dispersal Bed Area ÷ Bed Width <br />ft2 ÷ ft = ft <br />3. ABSORPTION AREA SIZING <br />A.Calculate Absorption Width: Bed Width X Mound Absorption Ratio <br />ft X = ft <br />B.For slopes >1%, the Absorption Width is measured downhill from the upslope edge of the Bed. <br />Calculate Downslope Absorption Width: Absorption Width - Bed Width <br />ft - ft = ft <br />4.
