Sharjah Municipality faced increasing irrigation demand in Al Qarayen. The existing treated sewage effluent (TSE) pumping station and reservoir could no longer handle peak loads or future expansion needs. At the same time, the system had to remain operational during the upgrade, meaning any downtime had to be minimal.
Gulf Water Treatment was entrusted with designing and executing a comprehensive upgrade to modernize the pumping station and construct a new TSE reservoir.
The upgraded station was designed to deliver a daily capacity of 60,000 m³, integrating advanced pumping, electrical, and automation systems. Four high-capacity pumps were installed in a duty/assist/standby configuration, ensuring resilience while allowing efficient operation under variable demand.
A new compressor-type surge vessel was introduced to protect the network against pressure shocks, and the station’s electrical and automation backbone was completely renewed. A modern MCC and PLC system was constructed to meet utility requirements, equipped with UPS backup and integrated into Sharjah’s central SCADA network for real-time monitoring and remote control.
Civil works were carefully planned to avoid prolonged service interruptions, with temporary bypass arrangements and phased construction. This included new foundations, selective reservoir modifications, and dedicated transformer and MCC rooms. The project strengthened connectivity to Sharjah’s irrigation network through integration of existing and new pipelines, providing a flexible backbone for future expansion.
To achieve the ultrapure quality required for sour gas treatment, the RO system was paired with advanced electrodeionization (EDI) technology. Unlike conventional mixed-bed demineralizers, the EDI process eliminates the need for chemical regeneration, providing continuous production of water with conductivity below 0.2 µS/cm. This innovation not only enhanced operational reliability but also aligned with the client’s sustainability goals by reducing chemical handling and waste.
The entire system was delivered in a containerized, modular format, pre-assembled within two high-cube containers. This approach minimized the need for extensive on-site civil works, shortened the construction timeline, and allowed for rapid deployment in a remote oilfield setting. Each container was internally equipped with marine-grade coatings, waterproof flooring, and environmental controls to ensure the equipment’s long-term durability under extreme conditions.
By combining proven water treatment technologies with modular execution, GWT provided the client with a future-ready asset that integrates seamlessly into existing operations while offering flexibility for expansion or adaptation in the years ahead.
