Actions doneModernisation of the water treatment facilities. First phase included construction of a additional water treatment station for water purification and start up of the facility in October 2011, the second stage consisted of construction of a pumping station, reagent facilities and a UV-disinfection facility with start-up in December 2012. These improvements have allowed the water to reach the hygienic criteria for drinking water. Modernisation of waste water treatment facilities, expected to be completed in 2019, will decrease the load of pollutants to the raw water source (Onego lake).
