The 'used water' that flows from our showers, dishwashers and toilets isn't a waste to engineers – it contains valuable materials. The challenge is recovering them and turning them into products.
Cities relied entirely on conserving and recycling water to get through the last big drought. We now have desalination plants, but getting the most out of our water reserves still makes sense.
Sydney and Melbourne are bringing desalination plants back on stream and Adelaide plans to increase its plant's output. Perth depends on desalination. But is it the best way to achieve water security?
Water supply systems weren't designed to deal with altering weather patterns brought about by climate change. This needs to change.
Water and power cuts prompted by reduced rainfall and drought in Southern Africa have caused major problems for business.
In the fight against cholera, new research in the DRC suggests that the rehabilitation of water networks would be more sustainable than other interventions whose effectiveness is debatable.
Logging in the Thomson Catchment could reduce water supply by the equivalent of 600,000 people by 2050.
South Africa is a water stressed country but crisis point can be avoided.
Energy-efficient water supply is a wicked problem – and we might have found a way to solve it.
Governing parties and officials need to take note of the frustration being expressed by ordinary South Africans.
Governments and private companies have been seeding clouds to create snow for decades, without proof that it actually works. A recent study peered into clouds in search of answers.
There are measures in place to manage Day Zero and beyond. Models show that these will not work.
Australian cities have turned to some very costly solutions when water is scarce. But as the world's second-highest users of water per person, more efficient use and recycling are key.
We know the tides affect the oceans, but it also affects groundwater. If we can understand how, then we can better protect this precious resource.
A five-year project announced today will implement an innovative water-sensitive approach tailored to informal settlements. The goal is to revitalise 24 communities in Fiji and Indonesia.
The invasive mesquite tree has a negative impact on everything from biodiversity to human health. Management programmes are crucial.
Can we predict where in the world will be water-stressed? Using a more fine-tuned model, researchers find there is no global water crisis, just local ones.
Despite its long idle, Melbourne's desalination plant plays a vital role in providing water in a drying climate.
