The need to build a supplementary water supply network in this area results from the lack of adequate pressure in the existing water supply system, which causes frequent disruptions in the water supply for the residents of Nowe Jaroszowice. This project was scheduled for completion in the first half of this year by a contractor selected through a restricted tender organized for companies specializing in the construction of water supply systems. The purpose of the tender was to select the most advantageous offer, including the completion date, the amount of the lump-sum remuneration and the warranty period.
