Water scarcity is a major issue in Australia's outback.
Most remote communities rely on groundwater for their daily needs - but groundwater often contains high levels of salinity, hardness, nitrates and other contaminants unsuitable for drinking. As such, governments spend $13.8 million annually trucking drinking water to remote Australian communities.

To combat this issue, engineering firms Aurecon and Ampcontrol have joined forces to create Project Gilghi – an innovative and practical drinking water solution for the Gillen Bore community in Australia’s Northern Territory.
Completely off-grid, the Project Gilghi water treatment plant uses photovoltaic (PV) solar panels and batteries to harness the power of the sun – an abundant, renewable resource in Australia’s outback.
The plant uses three well-established water treatment technologies to provide residents with up to 28 thousand litres of quality drinking water per day:
Multi-media filtration – to remove suspended materials from the water, such as dirt, sand, and organic matter
Reverse osmosis – to remove dissolved contaminants such as salinity and hardness
UV radiation – to ensure the water is sufficiently sanitised by killing any harmful bacteria and viruses
All three technologies are neatly housed inside a small shipping container that makes the plant simple to transport and install – a major advantage when delivering to remote locations.

The project has gained a lot of attention in 2020, winning several engineering awards for innovation, social impact, and design excellence.
Project Gilghi shows how innovative and practical engineering can not only benefit under-privileged communities, but also reduce costs to the Australian taxpayer and contribute to the uptake of renewable energy.
