Development of Geographical Information System (GIS) for water and sewerage networks in East Sarajevo
Dejan Romić, PUC „Vodovod i kanalizacija“ j.sc E. SarajevoVienna, May 7th
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
Why GIS?
The main priorities indetified in WSS Study by MDGF:Developing GISDevelopment of water supply system's hydraulic modelSCADA remote control system Network research and defect repair in water supply system
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
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
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
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
