Another important concept of mound design is absorption width, the width of original soil under the sand layer that is required for the treated effluent to infiltrate into the original soil. If this width is not provided the soil will not be able to absorb the effluent before it reaches the toe of the downslope dike, resulting in effluent surfacing.Total absorption area for the mound is the product of the length of the bed and the absorption width. Berms at each end of the mound are necessary to finish the mound and tie it into the landscape but are not
How Do You Determine Absorption Width?
For effluent to be absorbed in a mound system, you need to have a properly sized absorption width. Here’s how to do it.
