Comments Off on Tree branch water filter removes a surprising 99% of E.coli

Sometimes low-tech solutions make the most sense, particularly in developing countries with limited access to affordable technology. It often happens these same countries experience chronic water shortages, so MIT researchers designed a brilliant solution that relies on nature to clean up after itself. It turns out certain kinds of tree branches, when peeled, rival cilantro’s ability to scrub contaminated water clean of harmful bacteria. In an experiment, they found sapwood is capable of eliminating 99 percent of E.coli bacteria. The same properties that allow xylem tissue to transport sap from a tree’s roots to its crown traps bacteria and other particles over 20 nanometers in size.

Comments Off on ‘The Real Thing’ Machine Turns Coca-Cola Back Into Drinkable Water

These days it can seem like cola is absolutely everywhere, but drinkable water may not be. Helmut Smits wanted to take advantage of that contradiction with a machine he calls The Real Thing. The idea is to turn that unhealthy bottle of Coke back into clean, wholesome drinking water . The machine was featured at Dutch Design Week and Dezeen interviewed Smits to get the story behind the idea.

The Cloud Harvester Catches and Stores Fresh Water from Fog

Comments Off on The Cloud Harvester Catches and Stores Fresh Water from Fog

The Cloud Harvester is an ingenious device that is designed to catch and condense fog into water droplets which, in turn, run down a stainless steel mesh into a water storage container. The device represents a quantum leap in water collection efficiency, and it’s ideally suited for poor, rural, mountainous, coastal regions with little freshwater resources or infrastructure. It is almost as efficient as existing fog-harvesting devices that are currently on the market, but it is much smaller and more cost-efficient to produce and transport.

Berkey Water Filters Provide Clean, Fresh Drinking Water At Home and In Disaster Relief

Comments Off on Berkey Water Filters Provide Clean, Fresh Drinking Water At Home and In Disaster Relief

With bottled water and potable tap water both so readily available in developed countries, it’s easy to take clean drinking water for granted. But when natural disasters strike, one of the first things to sell out on store shelves is bottled water, and running water may be either turned off or compromised by pollutants. Domestic water purifying pitchers and faucet filters are perfectly fine for every day use, but most of them simply weren’t designed to filter untreated water like the kind you may need to drink in emergency situations. Unlike those other off-the-shelf, refrigerator-sized water filters, Big Berkey water filters were actually made to purify water from untreated sources like remote lakes, streams and stagnant ponds and are used by relief organizations such as UNICEF , the Peace Corps, and the Red Cross . They use a much more powerful filtration system that removes harmful pathogenic bacteria, cysts, parasites, and unhealthy chemical contaminants such as chlorine to levels higher than 99.99%, a capability that would be invaluable to your family in a disaster situation where you were unable to secure clean water. Big Berkey water filters can be a lifesaver in emergencies, but they’re also a smart, elegant and beautiful green product to use in your home on an everyday basis as a great alternative to bottled water or a refrigerator water filter because they filter water so powerfully, and the high-tech filters last for 3-5 years as opposed to a few months.

Comments Off on Drought-Stricken Texas Town Turns Urine Into Tap Water

Texas is in the midst of a drought so severe that local water management teams have decided to distribute reclaimed wastewater (aka urine). From toilet to tap, the treated wastewater will be mixed with reservoir remains for a refreshing and clean H2O cocktail.

The Bill and Melinda Gates Foundation Plans to Make a Waterless, More Sanitary Toilet

Comments Off on The Bill and Melinda Gates Foundation Plans to Make a Waterless, More Sanitary Toilet

The Bill and Melinda Gates Foundation is looking to reinvent the classic commode. Two and a half billion people in the world — about 40% of the population — don’t have access to a safe and sanitary way to dispose of their waste. The Gates Foundation realized that handing out water-guzzling porcelain bowls is probably not the answer, so they’ve partnered with the German government to support scientists that are working on the problem. The foundation envisions a water-free device that separates excrement from urine in order to dry them separately.

Water for People: Finding Better Ways to Deliver Water to People

Comments Off on Water for People: Finding Better Ways to Deliver Water to People

Water is an important issue globally, and with the world’s population hitting 7 billion this year and the impact of climate change growing, water will only grow in importance.  But the need for clean water and sanitation is not a new problem, and some wonder why the rate of progress seems so slow.  As the CEO of Water for People, and as someone who was worked globally on delivering clean water to people for many years, Ned Breslin is creating new solutions for this old problem. Image Credit: Water for People For decades now an aggregation of non-profits, foundations, government groups, and others have pursued a variety of tactics to deliver water, but the progress can seem frustratingly slow. “The effort is chaotic,” said Breslin, describing the efforts of the many parties involved in the global water challenge.  And the results are not always what they could be. Water for People works in 11 countries in Latin America, Asia, and Africa with the belief that everyone should have clean, safe water for drinking and sanitation.  It is a simple belief with the prospect to make a profound difference the lives of a great many people. One of the challenges with efforts to improve water supplies has been a tendency of groups to focus on the initial installation of projects and then move on.  After the initial pictures of water flowing and happy people, attention wanders off to the next project down the road. The result is often broken water projects, and wasted investments. “People come in, do a project, and then leave,” said Breslin.  Installing the project is only the first step though. “There are abandoned projects everywhere.  Keeping the water flowing takes money, work, and a continued presence.  The day the water first flows is only day one.” To solve this problem with the long-term performance of water projects, Water for People is measuring not just projects but outcomes, and to measure this they have incorporated long-term monitoring.  Independent monitors visit their projects once each year, usually at the end of the dry season when the water system is under its greatest stress, and the projects they install are to be tracked for 10 years to make sure they’re still working. “Technology helps to make this possible,” said Breslin. They have devised a system called FLOW in which data on water projects can be collected on phones, including GPS location. The data is uploaded to Google, and tracked on a map. With groups like Water for People leading the way, there will be more pressure for the field as a whole to show concrete results in the push for clean water. “Philanthropists are asking harder questions, pushing the move toward transparency,” said Breslin. The importance of water in the lives of people everywhere means that efforts to improve water won’t go away. Solutions are possible with better information, honest discussion, and measurement of outcomes like the work done by Breslin and Water for People.
