Vaasan Vesi was established in 1915 and we still proudly provide our customers with water supply services, of which the most important is to purify and deliver a high-quality drinking water, as well as manage and treat wastewater. We also build and maintain the water pipe and sewer networks and provide customers with planning consultation and expert advice. In the Vaasa region there is significant cooperation across municipalities when it comes to water supply and wastewater treatment. All in all, we serve over 70 000 inhabitants. Vaasan Vesi supplies parts of Korsholm with clean water, and receives sewage from parts of both Korsholm and Malax. The sewage sludge is turned into biogas at Stormossen waste treatment plant in Korsholm and it will be upgraded to run 12 of the city busses by the end of 2016.
