The excellent relationship forged between our Swiss branch, headed by Peter Widmer, and the Engadin St. Moritz Mountains AG ski area has been further strengthened by a project to build an artificial lake at Lej Alv.

With a capacity of 400,000 m³, the lake is the largest of its kind in Switzerland. As well as building the lake, the teams on our sites have worked also for other projects at St. Moritz, to ensure the upcoming season on the peaks of the Engandin gets off to the perfect start.

Two years ago DEMACLENKO built a pumping station for St. Moritz Mountains AG equipped with 14 pumps, seven of which had a total power of 2,500 kW, plus four 220 kW vacuum pumps and three 225 l/s capacity pumps for the cooling towers. In addition, two 60 kW bubbling system compressors were installed.
