First SlideWheel in the Western Hemisphere

Medusa’s Slidewheel

Wisconsin Dells, WI

Ramaker provided all required A&E services, including architectural design, aquatic engineering, civil engineering, geotechnical engineering, MEP engineering, surveying, and structural engineering services, for the installation of Medusa’s Slidewheel at Mt. Olympus Water & Theme Park in Wisconsin Dells, Wisconsin.

WhiteWater, a global leader in waterpark attraction design and manufacturing, supplied the groundbreaking water slide.

Medusa’s Slidewheel is the first rotating water slide in the United States. A feat of contemporary waterpark engineering, the slide is a raft-based four-person ride that combines the thrills produced by two classic attractions: a Ferris wheel and a water slide. The ride rotates like a Ferris wheel while riders are propelled forward by the water-generated propulsion of a slide.

Ramaker partnered with Holtz Builders for construction of Medusa’s Slidewheel. The slide received the 2022 Associated Builders and Contractors National Excellence in Construction’s Eagle Award, which honors innovative and high-quality construction projects.

Ramaker’s architecture and aquatic engineering teams have been involved with every feature installed at Mt. Olympus since 1998.

As a full-service architecture and engineering firm, Ramaker combines a variety of capabilities and experience in-house, allowing the firm to quickly and efficiently complete projects that require multidisciplinary expertise. Ramaker’s continued involvement with cutting-edge attractions has positioned the firm’s employee-owners as trusted aquatics consultants for waterpark design projects nationwide.
