Mapping and Hydraulic Modelling of Gaziantep Water Supply Network

Financing : Equity Capital
Service : Reducing Non-Revenue Water
Employer : General Directorate of Gaziantep Water and Sewerage Administration - GASKİ
Project Duration : 2011 - 2016

Services are being provided for;

Identification and mapping of pipes and armatures for 2300 km water supply network with diameters ranging from Ø1400 mm toØ80 mm
GIS establishment within GASKI, transferring of network map to GIS environment
Calibrated Hydraulic modeling with the help of SCADA system records and 'pilot' area studies
Identification of pressure zones and creating DMAs for loss/leakage reduction, and identification of priority investments
After hydraulic modeling works, with respect to resulting outcomes of the DMA’s 300km. detailed design of water supply network rehabilitation projects are prepared for GASKİ.
Pipes on the field are detected with utility locators and Geo radars.
Detected pipes are digitized accurately and mapped in accordance with the GIS of the administration.
With the data collected from the field, pressure zones are rehabilitated.
With the digitized GIS data, hydraulic models of the network are formed and DMAs are defined for the whole network
DMAs are defined according to the newest legal regulations that aim to minimize leakage
Pressure and flow measurements are carried out on various locations of the network to perform a basic calibration study.
SCADA measurements and customer database are integrated to calculate an annual water budget according to the AWWA Standards.
