Our Work

Western Irrigation Network (WIN) – Greater Western Water.

​Sequana played a pivotal role in the Western Irrigation Network (WIN), a significant recycled water irrigation scheme in the Parwan-Balliang agricultural district.

Responsibilities ranged from preparing inputs for the business case to project management throughout detailed design, approvals, procurement, and construction phases. Sequana’s team led the development of an implementation strategy, ensuring approval for Commonwealth funding and identifying fit-for-purpose assets.

We oversaw the construction of a new 1.1-GL recycled water storage and facilitated the contract award for the interconnector pipeline. With ongoing work packages tracking on time and on budget, WIN continues to progress as a result of Sequana’s comprehensive oversight and strategic guidance.
