Boabat Alnoor is delivering an integrated Groundwater Dewatering System for the Hammar Mishrif DGS-1 and N-DGS facilities in the Al-Zubair Oil Field, Basra, Iraq, for ZFOD / Eni Iraq B.V. The project is designed to control groundwater around existing buildings and facilities, protecting foundations, electrical systems and sensitive instrumentation from groundwater-related damage.
Boabat Alnoor's scope covers the complete EPC cycle — engineering, procurement, construction, installation, testing and commissioning — integrating civil, mechanical, electrical, instrumentation and automation works into one complete dewatering solution.
Groundwater extracted from the wells is conveyed through a network of HDPE pipes to an external collection pit. The pit is equipped with water level sensors, pressure transmitters and two submersible pumps operating according to a predefined control scenario to maintain the required water level and prevent overflow.
The system also measures the quantity of extracted groundwater and records the total volume in cubic metres. Collected water is then pumped through HDPE piping to an external discharge pit located outside the buildings for final discharge in accordance with project and site requirements.
The electrical and instrumentation package provides the power, measurement and field control infrastructure required for automatic operation of the dewatering system. The works include:
All field instruments are integrated with a centralized PLC control system that receives and processes real-time data from the wells and collection pit. Based on measured groundwater levels and predefined operating parameters, the system automatically starts and stops the submersible pumps through the Remote Control Units.
A centralized HMI provides operators with real-time visibility of water levels, pressure, pump status, pump faults, alarms and the total volume of groundwater extracted. This gives the control room continuous visibility of system and site operating conditions.
The integrated system provides continuous groundwater control, automatic pump operation and real-time monitoring while protecting buildings, foundations and electrical equipment. The solution is designed to support safe and stable operation of the Hammar Mishrif DGS-1 and N-DGS facilities.
