Sydney Water needed to improve the resilience of its wastewater network during wet weather events while optimising infrastructure investments. Traditional asset-based planning approaches were proving inefficient in managing overflows and environmental impacts.

Aurecon partnered with Sydney Water to develop an integrated system-wide strategy that leveraged advanced network modelling, digital tools, and predictive analytics. The approach enabled Sydney Water to prioritise investments, optimise existing assets, and enhance overflow management under different climate scenarios.

By adopting a data-driven, system-based planning approach, Sydney Water improved decision-making, reduced unnecessary capital expenditure, and strengthened service resilience – demonstrating the value of modernised planning systems in complex water networks.
