Why don't you collect stormwater?

Perth is characterised by predominantly sandy soils, which enable a lot of the stormwater to infiltrate into the ground.

Doesn't desalination use a lot of energy?

Yes, desalination does use more energy than sourcing water using traditional methods such as gravity feeding water out of a dam.

However, the energy used to provide enough desalinated water for the daily use for a family of 4 is the same amount of energy needed to run an air conditioner for just 1 hr.

Why don't you build more dams?

As we respond to the impact of climate change, we are refocusing our efforts to find a variety of sustainable solutions for the future. While dams continue to play an important role in WA’s water supply, they aren’t a secure solution when we look to the future. We’re focused on developing water sources that aren’t dependent on rainfall, such as desalination, groundwater replenishment and water recycling.

What happens to the salt from seawater during desalination - is it harming the environment?

Our desalination plants meet stringent environmental protection criteria and are designed to have minimal impact on the surrounding environment.

We have 2 plants, both located near the open ocean. Due to the high energy swell, the concentrated seawater discharged during the process mixes very quickly with the surrounding seawater. The offshore discharge and intake pipelines are designed and located to minimise any effects on sensitive marine habitats, such as seagrasses and reef systems.
