This task was carried out as part of the „Water supply and sewage treatment in Jelenia Góra – sewage and waterworks systems construction” project.
The main contractor responsible for the whole investment was the “POL-AQUA” S.A. Engineering Works Company. The drift dug by the company was indispensable for laying the treated water pipelines from one side of the Chmielnik Mountain to the other side, where the spare and pressure-equalizing tanks were located. Thanks to this contract Sebeka has strengthened its position on the growing market of specialist works, linked to environmental engineering.
