Sand spear technology developed to draw water from the Gascoyne River bed for growers

The WA Department of Agriculture and Food has commissioned a new design of "sand spear" to capture water in the Gascoyne River bed sands, before it flows out to sea.

Sand spears are a form of engineered pump, sunk beneath the ground.

This new design has been produced with input from local growers, hydrologists and following research into similar technology in Israel.

Gascoyne Food Bowl project manager, Tony Della Bosca, said the project is a step towards drought-proofing the region.

On Sunday United Utilities lifted the “boil water notice” on properties in Chorley, Preston and South Ribble. This follows the first phase of restrictions to be lifted last Thursday in other areas including Blackpool.

China is having a hard time stopping pollution of its scarce water resources

China published a water pollution prevention action plan in April, promising to improve water supplies in the world's most populous country and second largest economy after years of heavy pollution caused by industrial development.

One-third of major Chinese river basins and 60 percent of its underground water is contaminated.

Speaking at a meeting to discuss the country's efforts so far, Wang said preventing water pollution remained a "formidable task".

11 Tips for Conserving Water

Taking a long hot shower is something many of us take for granted, just like turning on the tap when we need to drink, bathe or cook. But for the 750 million people around the world who lack access to clean and safe water, finding enough to cook, clean, or bathe with is a harrowing daily ordeal.

'Bug-killing book' that cleans up to 100 litres of murky water passes field trials

A book with pages that can be used to filter murky drinking water has seen success in its first field trials.

The so-called "drinkable book" features treated paper which can be torn out and used to kill bacteria in water, as well as printed information on the importance of filtering drinking water.

The pages contain nano-particles of silver or copper which wipe out dangerous bacteria as they pass through the water.

Water-saving Nebia shower attracts $1.3 million in Kickstarter funding

A shower system produced by the startup Nebia raised more than $1.3 million in two days on Kickstarter after raising initial funds from such backers as AppleAAPL, +0.70%  Chief Executive Tim Cook and Google GOOG, +0.10% Chairman Eric Schmidt’s family foundation.

How to water the grass without guilt

Californians tempted to report Steven Sockolov at Twitter’s #DroughtShaming should first take note: The lush landscaping at his Mill Valley, Calif., home is quenched with recycled water.

Sockolov and his wife, Susan Snyder, bought their home in 2013 for $2.8 million -- and its gray-water system was a major selling point. The system captures and filters water drained from bathroom sinks and showers and repurposes it to irrigate their lawn.

96m water-saving shade balls released into LA reservoir

. The LA water and power department began pouring the balls into the water two months ago, as can be seen in the first clip, and the final balls are introduced this week

The idea was conceived in 2007 in an effort to prevent the reservoir becoming contaminated with bromate, a substance formed when chemicals in the water react with sunlight. The balls are a relatively low-cost solution, at $34.5m, and are expected to save about $250m over 10 years, and prevent 300m gallons of water evaporating

Send A Signal When Water Gets Polluted

It’s called FRED, for Field-Ready Electrochemical Detector, and it involves genetically engineered bacteria capable of sensing a variety of water-borne contaminants and in response, emitting an electric signal that indicates the level of contaminant.
