The implementation of the project called Expansion of the Economic Activity Zone in Wolbrom aims to develop the potential of the areas lying in the Economic Activity Zone by expanding the existing water and sanitary sewage system within the SAG and the construction of a new water supply system enabling the required quantities of water to be delivered to the SAG area. Task A: Construction of a water supply network with a diameter of 160 made of PE100 SDR11 RC PN16 with a length of approx.1171 m, connecting the water supply dn100 located on the side of ul.Zacisze on plot 964 with water supply fi 90 on plot 4970551 on the south side of Miechowska Street in the existing Economic Activity Zone. Task B: Construction of a water supply network with a diameter of 125 made of PE100 SDR11 RC PN16 with a length of approx. 309 m, in a road lane on plot 4970585 located in the central part of the existing Economic Activity Zone. The water supply will begin by entering the existing water supply system fi 125 on plot 4970582 and ending with a hydrant on plot 4970585 at the SAG border on the west side. Task C: Construction of a 271 m long sanitary sewage system dn200 from stone pipes, an extension of the existing sanitary sewerage network located in the road lane on plot 4970585 in the western part of the existing Economic Activity Zone. The network ends at the height of plot 4970575. Due to the unfavourable terrain that prevents the gravitational discharge of sewage on the network route, the construction of a sewage pumping plant is envisaged.The above tasks include the execution of all research, inventory, measurement, design work in the area of the necessary industries, earth, construction, installation and finishing works necessary to carry out these investments. It is also the subject of the contract to obtain all permits and arrangements necessary for the design, execution and delivery of the facilities.
