This project complements and completes the integrated management of urban sewage in Spetses, including collection, transport, treatment, and disposal. This need arose during the construction of the sewage pipeline in the area of the Ancient Baths, where antiquities were found, so the pipeline could not be constructed at the depths specified in the project study. Therefore, in the context of finding alternative solutions, taking into account the slopes of the area, the excavation depths, the limited space for work execution, and the possibility of draining adjacent properties, the Service deemed the construction of this network segment as a suction network as the most suitable solution.
The relevant construction works of the remaining network include the construction of gravity sewer pipes from structured wall plastic pipes in open trench, with a total length of 19,245.00 m; the construction of pressure sewer pipes from polyethylene segments in open trench, with a total length of 970.00 m; the construction of inspection chambers using precast concrete circular manholes, totaling 637 pieces; the construction of inspection chambers using precast synthetic material manholes, totaling 44 pieces; and the construction of a vacuum sewer network, including the preparation of its implementation study.
