Towards Integrated River Basin Management The 55 th Anniversary of the Founding of the Water Research Institute THE IMPLEMENTATION OF EWFD/WFD IN THE REGION OF VOJVODINA WITHIN JOINT SLOVAK-SERBIA SERBIA PROJECTS Milorad Miloradov, Steva Prohaska, Djula Fabian, Mirjana Vojinović-Miloradov Academy of Science and Arts of Vojvodina, University of Novi Sad, Serbia
JOINT PROJECTS The Slovak ODA granted two joint Projects to Serbia-Vojvodina for study and experimentally implementation of Water Framework Directives: 1. Integrated management of selected river basin complying with the European Water Framework Directive 2. Institutional support of integrated water pollution control and management in Vojvodina region in compliance with EU directives
Partners in realisation of Projects: Water Research Institute, Bratislava Slovak Hydrometerological Institute, Bratislava Academy of Sciences and Arts of Vojvodina University of Novi Sad, Faculty of Technical Sciences
PILOT UNITS IN VOJVODINA Palic Lake and its entire catchments The Nadela river basin, are selecting as the pilot units and they can serve as an example for elaborating and implementation the EWFD/WFD.
For implementation of EU WFD four steps are apply: 1. Translation all documents, and understand new terminology; 2. Study and analyzed experience of European countries - Slovak ; 3. Preparation of new Serbian law is in progress 4. Experimental implementation of the Water Framework Directives;
1.STEP 1. Translation all documents and understand new terminology Ministry for agriculture, forestry and Water resources management, Directorate for water organized integrated translation of main important documents
Understanding a new terminology Water bodies (Water resources) Pressures and impacts Modified water bodies Heavy modified water bodies Artificial water bodies Ecoregions (Water resources management regions) Good status (water classifications and river categorizations) Risk to achieve the good status of water
2.STEP Study and analyzed experiences of European countries Two activities are going on: A. Presentation and analysis of the Slovakian experiences; B. Analyses and Experiences of other European countries through activity of ISPDR;
Obtaining and analyzing the corresponding documents of the EU WFD B. Through cooperation with ISPDR Serbia realized activities; 1. Identify Surface Water bodies; 2. Identify Ground Water bodies; 3. Modified water bodies 4. Heavy modified water bodies 5. Artificial water bodies
3.STEP Preparation of new Serbian law In Institute of Jaroslav Cerni- Working Group for the preparation of the first proposals was established; Directorate for the waters formed the Commission of the Experts for the evaluation of the first Proposals
NEW SERBIAN LOW Draft Proposal of the new Serbian Low is given to ISPDR lawyer experts for evaluation with WFD The ISPDR lawyer experts gave the positive judgment to the Draft Proposals!
4.STEP Experimental implementation of the Water Framework Directives in two river basins: PALIC LAKE BASIN, and NADELA RIVER BASIN
Palić lake
Location: The Pannonian Lowlands, Serbia Province of Vojvodina -Latitude -Longitude Origin: filling up lowlands by groundwater and precipitation The highest point is in the North-West, 132.6 m referred to the Adriatic, while the average water level of the lake is 102.0 m.
Brief history The lake was mentioned first time as Paligo Palus in 1690. 19th century (Ladies( Bath,, Grand Terrace, Hydro-tower).
an ecological collapse in 1971 was happened due to the deposited silt of high organic content, introduced into the lake by untreated wastewater from Subotica.
The lake has been drained and de silted, divided in 4 sectors by 3 cross- dams.
In 1975 a wastewater treatment plant has been installed in order to control the inflow water quality (cca.. 30 000 m 3 wastewater / day)
The sub basin boundaries before the revitalization of the lake started in 1972.. Period of high water level oscillations. during the revitalization from 1972 until 1977 the bed of the lake is excavated, and subsequent the reconstruction works, the water level is fixed at 102.00m.
The overland boundaries of the Palic watershed (based on topology)
The overland catchment boundaries are partly natural (South-East) partly artificial (North-West) due to the vicinity of Subotica.. In determining the watershed the municipal sewer system had to be taken in consideration since treated wastewater is the main resource of water for the lake.
The surface water The water surface of the lake is 7.5% of total drainage area, while the surface of the city makes 17.5% of the overland catchment area. The overland boundaries of the Palic watershed are likely to change by time continuously due to the forthcoming urbanization.
The sub basin boundaries with high groundwater levels, the first aquifer The main direction of groundwater flow is from North- West to South- East, towards the lake.
The sub basin of groundwater can be generally divided into 3 layers. The upper unconfined layer spreads down to about 60 m. It is made of Pliocene sands. Due to human activities this layer is polluted. This resource is used for watering. Rough estimate is that there are several thousands of wells exploiting this resource. The second layer 60 to 200 m below the surface is the most used for municipal purposes (water supply, industry, agriculture, recreation, etc.). The third layer below 200 m. Several wells exploit thermomineral waters from depths of 400 to 500 m having temperature about 38 43 o C.
RECHARGE OF MAIN AQUIFER
Pedology The North-West part of the catchment is covered by antropic and eolic sands, on the South-East part chernozem on loess plateau is dominating.

Pressure and impacts to the water bodies
Anthropogenic impacts on the water bodies Land use, urban, industrial, agriculture and other facilities Point source pollution with substance from the ANEXU VIII, from the urban, industrial, agriculture and other facilities and human activities. Diffuse source of pollution
The lake has been serving for two functions: it used to be recipient of municipal wastewater (later industrial as well) from city of Subotica on one end, and served recreation (bathing, water sports ) ) on the other
Area covered by municipal sewer system, the brown dot is the WWTP
The plan of urbanization
Influence of anthropogenic activities on the first aquifer layer The localities of sampling
Public water supply, official municipal exploitation fields and wells Total discharge: 12 million m3/year
Besides of institutional exploitation wells there are other industrial point source pollution: Meat industry»29 November«,, 4 wells Diary industry»mlekara«factory of fertilizers,»zorka«,, several wells Crop industry,»fidelinka«industry of soft drinks,»next«,»sinalco«,, more wells Wine industry»podrum«, Palic,, more wells Veterinary Station, Subotica Electrotechnical industry»sever«, Subotica The Yugoslav Railways Chocolate industry»pionir«, Chemical industry»chemos«, Shoe factory»solid«, And others...
Point source of pollution Unofficial industrial wells exploit nearly the same amount of water as official municipal wells.
The future activities: Solutions and measures: To improve ecological status of water body, and Estimate the investment cost to achieve the good ecological status;
