1. Development of Geographical Information System (GIS) for water and sewerage networks in East Sarajevo Dejan Romić, PUC „Vodovod i kanalizacija“ j.sc E. Sarajevo Vienna, May 7th

2. Introduce WSS East Sarajevo PUC „Vodovod i kanalizacija“ jsc from East Sarajevo General data: –provides service for 32 000 residents with 10 500 water connections –3 main water sources are: Tilava (180 l/s), Grabski mlini (25l/s) and Ljustra (30l/s) –Water supply system length 190km and 70km of sewer system

3. Why GIS? The main priorities indetified in WSS Study by MDGF:  Developing GIS  Development of water supply system's hydraulic model  SCADA remote control system  Network research and defect repair in water supply system

4. Development of GIS Project of developing of GIS in East Sarajevo apllied to DWP on Call for Competitive Grants in September 2013 Project approved and started in February 2014 Costs of project: IAWD provides 42.500,00€ PUC „ViK“ E.Sarajevo provides 16.000,00€ 58.500,00€ Procurement carried out by rules of the World Bank

5. Development of GIS Before main activities on project has started we had to procure: -Consultant/GIS expert -Server -Geodesic equipment (GPS) -Software for GIS -Renting car for field work

6. Development of GIS Phases on project activities: -Gathering all previously used data in.dwg,.shp, and other formats and converting to.tab files (MapInfo format) -Making new layers with attribute structure compatible with hydraulic systems and models -Collecting data on field with geodesic equimpment -Training for GIS staff to work on GIS data

7. Collecting data from field

8. Development of GIS -Installing of SQL server with GIS database -Identification of all consumers into MapInfo and making link with economic information system -Making queries in MapInfo adjusted for many purposes -Making procedures for easier access to all kind of relevant data

9. Working space in GIS software Attributes for consumer Attributes for water pipes

10. Mix of queries for pipe system

11. Conclusion DEVELOPING OF GIS FOR WATER AND SEWER NETWORKS ENABLED: Optimization Of Water Supply And Sewer Systems Efficient Management Systems Hydraulic Modeling Detection Of Illegal Consumers
