Water Conservation

Recycling almost all your shower water and half of what you use in your washing machine, Hydraloop lets you re-use about 85% of your domestic water, significantly dropping your water usage for a unit cost of around US$4,000.

Given the current worldwide push for water conservation, it's certainly ironic that people are still flushing great quantities of the stuff down their toilets. They may soon be using much less, however, thanks to a slippery new toilet bowl coating.

A new sensor system is designed to catch polluters, by sampling and analyzing water within the sewer line.
-
ScienceOrdinarily, city officials only know about leaks in municipal water pipes once those leaks have become quite large and troublesome. A new artificial intelligence-based system, however, could catch such leaks much earlier – by listening for them.
-
When it rains heavily, even in arid places where water is scarce, the stormwater typically just runs off the streets and down the sewer drains. Thanks to a new "engineered sand," though, that road-polluted liquid could soon be cleaned up and used for drinking water.

Three years ago, the city of Los Angeles covered the surface of the LA Basin with 96 million shade-providing floating balls, in order to keep the water beneath from evaporating. Now, a new study suggests that the making of the plastic balls may have have used up more water than they saved.

A desalination project proposed for California’s central coast would draw water from one of the world's deepest submarine canyons, making it potentially less harmful to ocean life. The Deep Water Desal facility would require substantially less energy to operate than typical desalination plants.

ScienceEngineers at the Washington University in St. Louis (WUSTL) have developed graphene-based biofoam sheets that can be laid on dirty or salty dams and ponds to produce clean drinking water, using the power of the sun.
-
In the average distribution system, as much as 30 percent of treated water is lost due to leaks, but the problems can be hard to pinpoint. Now, researchers have developed a technique that could have a big impact on the problem, using “noise logger” devices to spot underground leaks.
-
Many parts of the world are facing unprecedented shortages of water. A design team based in drought-ridden California has come up with a new device to help people consume less water. Droppler taps into the human mind to trigger behavioral change.
-
A new initiative by the Los Angeles Department of Water and Power (LADWP) has taken a surprisingly low-tech approach to water conservation, by covering the LA Reservoir in 96 million black "shade balls." It's an attempt to combat water loss through evaporation, and to heighten water quality.

If you're enjoying a serene natural area, you might not appreciate seeing a very techy-looking pollution-hunting robot putting along the surface. That's why scientists have developed an alternative – water-quality-monitoring robots that look like swans.
