Towards climate resilience
As WA continues to experience the effects of a drying climate, planning for water services to meet future demand is ever more important. In 2009, Water Corporation released its 50-year plan, Water Forever: Towards Climate Resilience. The principle of becoming more climate resilient is now applied to all planning for water services across the state.
Water Forever provides a portfolio of options to manage water demand and supply to 2060 by:
- reducing water use by 25%
- increasing water recycling to 60%
- developing up to 100 billion litres of new water sources.
The effects of Perth’s changing climate
In Perth the changing climate has become more noticeable in the past 10 years, presenting new challenges. Reduced rainfall, and changes in rainfall timing, have greatly reduced runoff into dams and dramatically reduced their role in our drinking water supplies. Water Corporation plans to sustainably drought-proof Perth by:
- transferring groundwater abstraction to deeper aquifers to protect the groundwater environment and secure groundwater supplies
- replenishing deep aquifers with recycled water through a groundwater replenishment scheme
- expanding seawater desalination capacity to offset the declining inflow to our dams
- continuing to make gains in water use efficiency
- using wastewater recycling as a resource for industry, public open spaces and agriculture.
Delivering sustainable water & wastewater services
Water Corporation will continue to deliver sustainable water and wastewater services to the state by ensuring the following:
- In the South West, the Bridgetown Regional Water Supply Scheme is supplemented with groundwater from the Yarragadee aquifer and will be expanded to progressively connect other towns.
- Through planned investment the Great Southern Region's climate resilience will be increased by working towards interconnecting more schemes and exploring new water sources.
- In the Goldfields Agricultural Region, the Goldfields and Agricultural Water Supply Scheme will be maintained. Expected population growth in Esperance will also be supported.
- In the Mid-West, a staged approach will see expansion of the borefield supplying the Geraldton Regional Water Supply Scheme.
- For the fast-growing North West, the priority is to deliver more water and wastewater services while working with the community to reduce the region's high water use. We are making major investments in the investigation and development of new water sources and upgrading existing schemes.
- Across the state, we are committed to increasing recycling of wastewater from 13.5% to 30% by 2030.
