Case Study

Since the 1970s, the South-West of Perth has been struggling with impacts of the drying effects of climate change. This long term change in weather patterns has made it difficult to managing water resources.

One of the main problems Perth is facing is how to manage water supply systems like reservoirs and self-supply water systems, such as rain water tanks and dams.

To ensure future water security the region needs to continue to be proactive in their planning and resource management.
