At the end of the year 1970 and at the beginning of the year 1980, the objects for the sewage treatment and 56 km of sewerage system constructed. Together with these the main collectors anticipated by the project solutions were constructed, except for two collectors in the streets Đura Jakšić and Svetozar Marković, so that about 50% of the secondary waterworks from the nearby streets do not have the conditions to connect to the main collector network. Therefore the appropriate priority should be given to the construction of the collectors in the above- mentioned streets.
Besides above-mentioned, in order to finish the program of the sewerage system in our town, it is necessary to construct another 50 km of the collector primary and secondary sewerage system. The importance of these capital investments in the construction of incomplete sewerage system lies in the need to stop the further pollution of the subterranean waters that our town uses for water supply.
Five objects for the overpumping of the sewage have been constructed in the sewerage system. The main sewage suction station as the collecting system overpumps the sewage under the DTD canal to the waste water treatment plant. In the town that lies on 4 flowing areas there are 4 suction stations constructed, but there are also 3 flowing areas where appropriate suction stations have not been constructed yet, which means that sewerage system has not been developed in these locations so far.
Current problems
- complete construction area has not been comprised by the preliminary design
- not all of main sewerage collectors have been built
- more than 50% of secondary sewerage network has not been built
- the construction of the lacking sewerage network creates the conditions for the rebuilding of the existing absorbing wells and septic pits in order to protect the subterranean waters from pollution
- lack of high pressure auto cistern for the maintenance of sewerage network
- it is necessary to reconstruct the main collecting suction station and to replace the depreciated centrifugal pumps
- lack of automatic device for the solid waste removal on the main suction station
- it is necessary to replace the sinking fecal pumps on the other suction stations
Elements of development
- construction of main collector from “Zivinopromet” to “Fadip” and in S. Markovic street, 400-300mm in diameter
- construction of main collector in S. Kojic street and Dura Jaksic street, 350-300mm in diameter
- construction of secondary Sewerage network 250mm in diameter
- construction of tertiary Sewerage network 200mm in diameter
- acquisition of high pressure auto cistern for the maintenance of stromwatwer network and sewerage network
- acquisition of centrifugal pump for suction stations Q=10-15 l/s, H=7m
- construction of sedimentation device and spiral grid on two suction stations
- reconstruction of main suction station (rough grid, centrifugal pump Q=200l/s, H=13m
