As part of its long-term masterplan to strengthen Abu Dhabi’s water transmission network, Abu Dhabi Transmission & Dispatch Company (TAQA Transmission) initiated a major infrastructure upgrade for the development of a state-of-the art water transmission scheme in the capital.
The project was a strategic infrastructure of the Unit III Water Transmission Scheme aiming to increase the water pumping capacity by 48 MIGD and ensure seamless interconnectivity between transmission lines across Units III, IV, and V.
Key components included construction of DN1200 mm pipelines with integrated Fiber Optic Cable (FOC), upgrades to interface points, and integration with SCADA systems – all demanding robust and reliable valve solutions.

Customer requirement and scope of work
The customer’s key requirement for the success of this scheme was the supply of large-size Manual and Motorized Butterfly Valves, ranging from DN600 to DN1800 with extremely tight lead times due to the strategic importance of the commissioning schedule. Lead time was critical, given the large valve sizes and the pressure to meet demanding project milestones.
AVK’s district offering and competitive edge
The project drew strong attention from several international suppliers, each eager to secure a foothold in the district network. However, AVK’s long-established collaboration with its local partner, Dutco Tennant, proved decisive. With a deep understanding of the client’s expectations and working practices, Dutco Tennant was instrumental in reinforcing AVK’s position, ultimately narrowing the field and removing competing bids from consideration.
AVK’s ability to deliver was further underpinned by the strength of AVK Anhui’s advanced manufacturing facility in China. Specialised in the production of large-diameter valves, the facility provided a clear advantage in both capability and control. By owning and operating our own casting and foundry processes, AVK maintained full oversight of metallurgy, surface finishing, and quality consistency. This vertical integration translated into shorter and more dependable lead times, giving the client confidence in programme certainty and supply chain resilience.
The proven design and long-life performance of AVK Butterfly Valves under critical service conditions further strengthened our position. What stood out most was our local presence and technical responsiveness. From design discussions to execution, the AVK team remained closely engaged with the client throughout the project, addressing queries, validating requirements, and adapting quickly to evolving site conditions. This proactive, hands-on approach positioned AVK not just as a supplier, but as a trusted partner, one deeply invested in the project's successful and timely delivery.
