The water from various valleys is collected in the Zervreila reservoir above Vals near the Rheinwaldhorn, and used to generate electricity in three stages and in three stations. The annual production is sufficient to supply some 110,000 households with electricity. Thanks to the reservoir, 55% of the electricity can be generated during the high-demand winter months.
