A Non-Stationary Climate reduces the reliability of historical baselines for water planning. Sydney Water is strengthening System Flexibility and expanding Rainfall-Independent Supply through Purified Recycled Water, Desalination, and Nature-Based Solutions to improve resilience to drought and flood risk.
| Resilience Strategy | Mechanism / Project | Adaptive Outcome |
|---|---|---|
| Supply Diversification | Desalination & Purified Recycled Water schemes | Targeting 60% rainfall-independent supply for the region. |
| Stormwater Adaptation | Blue-Green Infrastructure in Mamre Road & Aerotropolis | Replacement of concrete channels to mitigate Urban Heat Island effects. |
| Decentralization | Upper South Creek Advanced Water Recycling Centre | Integrated treatment and environmental restoration for growth. |
| Landscape Retention | WSUD | Enhanced waterway health and natural biological filtration. |
How does System Flexibility address Non-Stationary Climate risk?
Traditional build-and-expand models become less effective when hydrological variability increases. System Flexibility prioritizes modular and hybrid infrastructure that supports adaptive responses across drought and flood conditions.
What are Sydney Water’s Adaptive Infrastructure pathways?
Sydney Water is decentralizing its network and disrupting traditional west-to-east flows through the Resilient and Reliable Water Supply program. Key components include:
- Rainfall-Independent Supply: Investment in Desalination and Purified Recycled Water.
- Regional Stormwater Authority: Managing growth precincts like Mamre Road and the Aerotropolis with blue-green assets.
- Advanced Recycling: The Upper South Creek Advanced Water Recycling Centre combines advanced treatment with local environmental restoration.
Frequently Asked Questions
What is Rainfall-Independent Supply?
It refers to water sources like Desalination and Purified Recycled Water that do not rely on precipitation patterns to support urban water security.
How does Sydney Water manage Non-Stationary Climate risks?
By diversifying water origins and strengthening System Flexibility through modular infrastructure and Nature-Based Solutions.
What is the role of Blue-Green Infrastructure in Sydney?
In growth precincts like Mamre Road, it supports heat mitigation and improves waterway health by prioritizing natural and hybrid water systems over concrete channels.
