The project concerns the construction of a new external water supply network in the settlements of Sideras and Liberes and includes the construction of a water supply network from HDPE pipelines of 12.5 atm and 16 atm of various diameters with a total length of 4,922.922.00 m, as well as the construction of the necessary isolation, control, branching, evacuation and airway wells for the smooth operation of the network. This project definitively resolves the operational problems of the external network and addresses the limited supply of drinking water in the two settlements by upgrading the quality and quantity of water supply.
