The scope of extension of mine KWB Adamów S.A. included the designing and construction of water drainage from open pit „Koźminˮ. It was also necessary to construct a road above the open canal discharging storm water from the mine for the transport of heavy technological equipment and thus the need to use the culverts transmitting substantial load. For the purpose of the project the Uponor Infra culverts were selected, which were made from Weholite DN 1600 mm pipes of the length of 15 m with slopes 1:1. They were delivered to the construction site as elements ready for installation, which significantly reduced the construction time.
