Semmering, Austria

SMI Super Wizzard Snowmaker at Semmering, Austria

The flagship ski resort of eastern Austria and host of the Women's World Cup, Semmering needed to produce significantly more snow in shorter timeframes at marginal temperatures while navigating extreme warming trends, limited water supply, and lengthy permitting processes for a new reservoir and pumping system.

Objectives and Solutions

Considered the flagship ski resort of eastern Austria and located one hour outside the capital city Vienna, Semmering is a high-profile destination hosting some of the industry’s most popular races, including the Women’s World Cup.

Due to extremely warm temperatures in recent years, compounded by a limited water supply, Semmering faced the challenge of making more snow in a shorter period of time at marginal temperatures.

Timing was also a critical factor in getting a new lake and pump system in place while waiting through a lengthy permitting process. Resort managers needed not only a system with the water capacity for future expansions but also sufficient time for the reservoir to fill.

Careful planning and engineering by Wintertechnik Engineering (WTE) in collaboration with SMI resulted in an efficient and timely installation, allowing a very successful start-up this season.

Working in partnership with (WTE), SMI’s early detection of and immediate problem-solving response during early testing phases sealed the new relationship, and helped move the resort owner’s multi-year snowmaking investment plan one giant step forward with an improved reputation for “guaranteed snow.”
