Preparatory Survey on the Sewerage System Improvement Project for the City of Belgrade in Serbia

Japan International Cooperation Agency (JICA)
Term of Project
2012 - 2013


The Republic of Serbia is a landlocked country located in middle-western part of the Balkan Peninsula. Belgrade City, the capital of Serbia, is located at the confluence of the Sava and Danube rivers. Most of all the cities have sewerage systems and about 20 sewage treatment plants are in operation all over the country. However, there is no sewage treatment plant in Belgrade City, and as a result untreated sewage has been released into the Sava and Danube rivers.
Without improvement of said unpleasant sanitary condition, the source of water supply in Belgrade including surface water and underground water will deteriorate,leading to health risk for the residents. In Addition, Serbia has made EU accession as top priority of their policy. For EU accession, Serbia must comply the EU regulations including installation of advanced sewage treatment facilities.

We conducted this comprehensive survey, supplementing with the past survey carried out by the city of Belgrade, to propose the optimal implementation plan of sewerage system for accelerating Serbia's EU accession.

Project Summary

In the first phase, we carried out the survey on the current situation and preparation of outline design of the implementation plan of sewerage system in Belgrade.

We carried out survey on the current situation on the sewerage sector of Belgrade, analyses on water environment related issues and its causes, issues against improvement and management of sewerage system, related law structure, and forecasted environmental and social impacts.
In addition, we invited the 10 members from the counterpart to Japan to improve their knowledge necessary for technical consideration, to introduce various Japanese treatment facilities and technologies, including biogas power generation technology, sludge-to-fuel technology, industrial wastewater treatment technology, and advanced treatment technology.

In the second phase, we carried out consideration on the optimal implementation plan and checked project impact.
We conducted the basic design, cost estimation, economic and financial analysis, studies on environmental and social impact, operation and maintenance system, and capacity of the executing agency. Finally we compiled above into a final report.
