The project includes the extension and reconstruction of the sewage treatment plant in Sulęcin, the modernisation of the sewerage system, including the distribution of general drainage into sanitary and rain drainage, the reconstruction and renovation of the water supply network and the extension of the SUW in Sulęcin. The capacity of the treatment plant is unchanged and will continue to be 14 234 RLM. On the other hand, solutions will be implemented to remove nitrogen and phosphorus to the parameters required by law. Standards in this area are now being exceeded. In addition, the use of sewage sludge for agricultural use will be improved. On the treatment plant will be made, among others: transport sewage sink, raw sewage pumping plant, blow and moss station. cleaning, chemical phosphorus precipitation station, 2 biological blocks, moss dehydration building, lime tank, dehydrated sediment warehouses, oxygen stabilisation tank, moss thickener. sediment. In view of the planned unbundling of the sewage system, the treatment plant will be rebuilt with a view to the acceptance of rainwater. The modernisation of the sewer system also includes the renovation of sections in poor technical condition and the exclusion from operation of worn sections. In the area of water supply, works will concern the construction of new sections of the network, renovation of sections in poor technical condition and extension of the SUW (2 techn. buildings and 2 clean water tanks). Output indicators will be implemented: Number of reconstructed waste water treatment plants – 1 units; Number of waste water treatment plants supported by the treatment/management of sewage sludge – 1 units; Length of the remodeled sanitary sanitary system – 2,05 km; Length of the refurbished sanitary sanitary system – 3,91 km; Length of the water network built.– 4,20 km; Length of the reconstructed water network – 1,27 km; Length of the refurbished water network – 1,26 km; Number of water treatment stations supported by 1 units; Results indicators will be implemented: Number of additives. persons benefiting from improved purification
