Summary of Information for the Municipal High Priority Hot Spots

Technical Reports Part C: Water Quality, Annexes 193 Name of the Hot Spot: City of Belgrade (Central Sewage System) Name of the receiving water : Danube River River km of the effluent discharge : 1165 Critical Emissions Discharge (m 3 /y) 146,000,000 BOD 5 (t/y) 35,040 Tot N (tn/y) 5,840 Tot P (tp/y) 1,314 Susp. Solids (t/y) 28,850 The CDF-critical dilution factor (Q 95 :Q effl ), is rather high (i.e. 450-500) accounting at whole river flow but in the mixing zone after bank outlet of sewage, CDF is around 80-120. The emission affects water quality but doesn t change it dramatically even in the mixing zone. Seasonal Variations There is no Municipal WWTP. Actually, there are Immediate Causes of Emissions several sewage outlets distributed along 5 km river stretch. It is planned to connect all of its to main collector (i.e. Interceptor). Root Causes of Water Quality Problems The emission of pollution from a large Metropolitan area located on the riverbank. The lack of money for investment. Receiving Waters Direct outflow in the Danube River (right bank) The impoundment of surface water for the Small Water Treatment Plant (capacity ~ 5000 m 3 /d) supplying the southern suburban area of the City is Nearby Downstream Uses located 10 km kilometers downstream of the planned sewage outflow. Also, there is a large recreational area downstream of sewage outlet. There is no direct transboundary implications (the beginning of the stretch making the State border with Romania is 100 km downstream of Belgrade) but Transboundary Implications rather indirect ones because of large emission of pollution.
