The Problematic of Sewage System Reconstruction in Urban Areas

Sewage systems are designed and constructed for a certain exploitation period, usually from 25 to 50 years. However they remain in use even after the end of that period, so to keep them effective it is usually necessary to make reconstructions of parts or the whole system. In this paper the problem of reconstruction of sewage systems is analyzed first by showing modern procedures of sewage reconstruction, rehabilitation and renovation and than by analysing changes in sewage system’ s characteristics during exploitation period that can affect the selection of the best procedure to use for sewage reconstruction. These changes in sewage characteristics are analysed on the example of Rijeka City sewage system (Croatia).
