Today Vodokanal LLC is the main provider of cold water supply and wastewater disposal services to the population and industries in Novokuznetsk. In the 1990s, the conditions of the networks and the economic situation in the country required the search for advanced time-effective construction and repair technologies at minimum use of resources and finance for the most efficient performance of work.
