pump well (Figure 9.1). Wastewater is treated as it moves through the sand mound, then further treated and disposed of in the soil underneath the mound. Figure 9.1 Components of a Wisconsin sand mound system A level area is best for building Wisconsin sand mounds, but a gently sloping site will also work.
On-lot sewage treatment and disposal may be the only means of disposing of the wastewater flowing from toilets, sinks, and appliances within your home. An on-lot sewage system is a two-stage treatment system consisting of a treatment tank (most commonly a septic tank) and a soil absorption area. In short, the treatment tank removes most of the
F 164 Elevated Sand Mounds for On-Lot Wastewater Treatment
Elevated Sand Mounds for On-Lot Wastewater Treatment Albert R. Jarrett, Professor of Agricultural Engineering Raymond W. Regan, Professor of Environmental Engineering T he purpose of this fact sheet is to explain what an elevated sand mound is and how, on sites requiring sand mound absorption areas smaller than 2500 square feet, they should be con-
To provide for on-lot treatment of wastewater in soils with between 20 and 60 inches of suitable soil available above the limiting zone, Pennsylvania has approved the use of elevated sand mounds. The elevated sand mound, a constructed mound of sandy fill material placed on top of the 20 to 60 inches of natural or prevailing soil, has been shown

areas. For elevated sand mounds, a Perc Rate between 3-180 minutes per inch is required. For absorption areas that require a Perc Test, the absorption area is sized by taking into account the site’s Perc Rate and the home’s maximum expected wastewater flow, which is based on the number of bedrooms. For example, a three-bedroom home may

Simply because in both cases for the waves as well as for the run-up the 2%-values are used. Practically it gives problems.
