North Point Recreation Area

South Dakota Game, Fish & Parks; near Pickstown, South Dakota The North Point Recreation Area is a popular campground on the shores of Lake Francis Case just upstream of Fort Randall Dam in southeastern South Dakota. The recreation amenities include camping, boating, and fishing facilities managed by the South Dakota Game Fish and Parks. In recent years, the park has experienced problems with the septic tank waste disposal system stemming from two major causes, increased usage of the park, which generates more wastewater, and fluctuating groundwater (and sometimes floodwater) caused by the rise and fall of the reservoir. The drain fields used for wastewater disposal have, at times, been rendered useless by floodwaters or high groundwater levels. During these times, use of the park has been restricted, and thus plans for further development of the campground were put on hold. Further complicating the situation was the recent discovery of Native American cultural artifacts and ancestral burial grounds located in various areas of the park. The engineering solution to the waste treatment problem needed to take the cultural and archaeological conditions into account and make as small an impact on the park as possible. Several alternatives were explored as viable solutions. They included: an evaporative lagoon, pumping the wastewater to a nearby municipal wastewater lagoon, and a mechanical treatment package plant. Ultimately the most cost effective solution proved to be the use of high capacity leaching chambers installed in a centralized drain field outside of the floodplain. The leach field was designed so that wastewater flows are uniformly and automatically dispersed by specially designed distribution control structures into two groups of interconnected cells. The North Point leach field, the largest application of this technology in the State of South Dakota, eliminated odor concerns, is invisible to the users of the park, was located in a culturally cleared site, and was constructed at 30% to 40% less than the cost of conventional alternatives. As a result of their innovative and cost effective design, Eisenbraun and Associates was awarded the “Grand Honor Award” in the 2006 Engineering Excellence Awards Competition sponsored by the South Dakota Chapter of the American Council of Engineering Companies.
