The Dolliver Memorial State Park provides its visitors with many activities like hiking trails, fishing, and boating. It also has campgrounds and rental cabins that overlook the Des Moines River. At this park, Romtec was asked by the Iowa Department of Natural Resources (DNR) to design and supply a waterless restroom building that was durable, as the park experienced occasional flooding. The restroom also needed to meet the DNR’s design standard, which include a timber post roof extension, slat siding, and a short stone wainscot. The finished project gave the Iowa DNR a restroom that not only fulfilled the durability that the park wanted but also was able match the look of the buildings that were around it.
