It shouldn’t be news to anybody that disposable plastic water bottles and the water that fills them are a bane to our planet. Some 38 billion plastic water bottles end up in landfills each year, and filling a one liter bottle takes three times that amount of water to produce.
So it really ought to be a no-brainer that we should be using refillable water bottles for our own personal use. However, if you’re concerned about the quality of water you use to fill yours, perhaps it’s time to consider a personal water filter bottle – and not just any one, but one that will also help to fund the fight against the global water crisis by supporting sustainable water projects.

Billions of people lack access to clean drinking water and researchers are constantly searching for cost-effective ways to purify water for rural villages and developing areas. A team of researchers has come up with just such a possible solution using “super sand,” or sand coated in an oxide of graphite.
Using sand to purify water is already an old strategy, but researchers from Rice University in Texas think that by coating it with graphite, the “super sand” will purify water more quickly and effectively than ever before. The BBC reports that coarse sand doesn’t purify as well as fine sand, but fine sand purifies very slowly as water percolates through. The new process could harness the best qualities of both.

Solar water disinfection (SODIS) relies on the freely available ultraviolet and infrared rays of the sun, which can disinfect by killing pathogens that contaminate water. The process is as easy as leaving a clear plastic bottle of water out in the sun for six hours.
If clean water is that easy, why are so many people, especially young children, dying from diseases contracted by drinking unclean water? There is a major obstacle to effective use of SODIS: if the water is muddy or murky, pathogens can hide in the shadows of the particulates, avoiding the death-rays of the sun. Read more
There’s a lot to know about the world’s water crisis–as you can tell from the month of posts we’ve been doing on just this one topic. But if you’re new to the discussion, catch up in one weekend with these five documentaries. From in-depth background on the political, social, and economic factors that are causing the crisis to personal stories from people affected by it, you’ll understand the problem in a whole new way.
This seven-episode set (don’t worry: each is only about 22 minutes) highlights the way the water crisis affects everyday life in Bangladesh, Cambodia, Fiji, India, Kiribati, Philippines, Thailand, and Tonga. Watch as a community joins together to rescue a coral reef in Fiji, as women in India fight shortages by finding new ways to transport water, and as a handful of other men, women, and children stand up to claim enough clean, safe water for themselves and their neighbors.

Our ever-increasing population is stretching our ability to provide clean water for our needs, from agriculture and manufacturing to the most basic one of all: drinking water. But recent innovations in water technology may have some answers on tap to that problem.
1. Smart Water Metering:
Smart water meters go above and beyond the capabilities of the basic meter on the side of your house, enabling users to monitor their water usage more accurately (and only pay for the water they’ve actually used), and help water suppliers to identify leaks and thefts, as well as see where and when water usage is highest (and to charge accordingly).
