What does a city with IWM look like?

Greener

Cooler

Secure water supply

Healthier environments

Resilient

Liveable and effective places

Impacts of stormwater on the environment

Natural Urban

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Our challenge: rebalance the urban water cycle

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Constructed Wetlands

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Bioretention (rain gardens)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Passively irrigated urban streetscapes

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Passive irrigation really works!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Porous Pavement

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Waterway protection and naturalisation

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Harvesting and reuse - rainwater

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Harvesting and reuse - stormwater

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - �

Which options? And where?

Planning in an uncertain climate future

A changing climate will bring a range of challenges for water management in the future, including:

• More frequent heat waves
• Reduced potable water availability
• Hotter, drier landscapes means we need to deliver:
• Diversified, resilient water supplies
• Greener and cooler urban environments
• More frequent heavy storm events means we need to:
• Plan for and mitigate more extreme flooding
• Address declining water quality
