What is desalinated water? The desalination process separates dissolved salts and other minerals from seawater to produce drinking water. It uses an advanced technology called reverse osmosis to remove the salt. The water produced is called permeate and is similar to distilled water. Permeate is then re-mineralised so it can be blended with other treated water or directly distributed to homes, businesses and industries in the region. Unlike the majority of drinking water produced in South East Queensland, desalination does not rely on rainfall and is a critical, climate-resilient water source during drought and flood. Why do we need desalinated water? Water is a precious resource, with less than 2% of the world’s water available for drinking. Currently, the majority of water provided to more than three million South East Queenslanders is dependent on rain. We live in a climate of extremes, and with a growing population, desalination offers an alternative source of drinking water in times of flood and drought. Desalinated water can be pumped to the Robina Reservoir at Clover Hill, where it is mixed with treated water from Hinze Dam or Little Nerang Dam. The blended water is distributed to many areas of the Gold Coast and can also be pumped north to Brisbane through the Southern Regional Water Pipeline. Is desalinated water safe to drink? Yes. Desalinated water meets public health regulation standards and the Australian Drinking Water Guidelines 2011. It is regularly tested to ensure it is clean and safe. The plant can produce between 44 and 133 million litres of desalinated water a day. As at 2015, there were more than 90 desalination schemes across Australia with the capacity to produce 879,461 million litres of desalinated water each year. Fact sheet About the Gold Coast Desalination Plant August 2017 The Gold Coast Desalination Plant turns sea water into drinking water for the Gold Coast, Logan and Brisbane. The plant is a climate-independent source of water that can be used in times of extreme weather and if our conventional water treatment plants need to be offline. Fast facts • The plant produces up to 133 million litres of pure drinking water a day - equivalent to 50 Olympic-sized swimming pools. • It generally operates in standby mode (33%) and, if required, can reach 100% capacity in 72 hours to supply up to 600,000 people with drinking water • The plant uses energy recovery devices to improve the energy efficiency of producing drinking water.
