TAQA Water Solutions operates over 250 pumping stations in the Emirate of Abu Dhabi. We have conducted a hydraulic assessment of the existing collection system for Abu Dhabi, Al Ain and Al Dhafra regions. The physical data for pumping stations has been collected through geospatial systems, while dynamic data, including flows, is gathered from SCADA. Both data sets are used for system calibration in the new hydraulic model.
