The City of Wanneroo relies primarily on groundwater to irrigate public open spaces, ensuring parks and reserves remain green and welcoming for the community. Our commitment is to use water efficiently, balancing sustainability with community expectations for healthy, vibrant spaces.
About groundwater
Groundwater is water stored beneath the Earth's surface in the spaces and cracks within soil, sand and porous rocks. It is primarily replenished by rainfall.
Why groundwater matters
Groundwater is a critical resource for the region, supporting:
- Public irrigation for parks and recreational areas.
- Natural ecosystems, including lakes, wetlands, and bushlands.
- Drinking water supply, managed by the Water Corporation.
The Gnangara groundwater system
The City draws water from the Gnangara groundwater system, one of Western Australia’s most important water sources. This system sustains local biodiversity and provides water for multiple users:
- Water Corporation for Perth’s drinking water.
- Licensed commercial users.
- Domestic bore owners.
All groundwater extraction is regulated by the Department of Water and Environmental Regulation (DWER) to ensure sustainable use and protect this vital resource for future generations.
