Solaqua draws on the sun to provide safe drinking water. June 3, 2009 While clean, safe water is in short supply in much of Africa, there's no shortage of sun. The Solaqua is a nifty portable device that uses the sun's rays to purify contaminated water. Through innovative use of readily available materials, it carries, disinfects and stores water, providing a safe, environmentally sustainable source of water for rural communities. Millions of deaths each year from water-borne and water-related pathogens could be prevented with clean water, sanitation and hygiene. Diseases such as cholera, typhoid, dysentery, and malaria are rife in sub-Saharan Africa where two in five people lack safe water for drinking and washing hands, food and utensils. Access to uncontaminated water would help to reduce the incidence of diseases. Solar water disinfection (SODIS) is a simple, low-cost way of improving the microbiological quality of water: heat and UV radiation work together to inactivate the pathogens that cause disease.
Karen Sprey. SODIS METHOD. Water can be disinfected and in this way made drinkable using the rays of the sun. "Solar water disinfection" - SODIS for short - thus offers a solution for preventing diarrhoea, one of the most common causes of death among people in developing countries. Clean drinking water in 6 hours The SODIS method is ideal for treating water for drinking in developing countries. All it requires is sunlight and PET bottles.
How does it work? People can use the SODIS method to treat their drinking water themselves. Research Many scientific studies confirmed the effectiveness of the SODIS method. International recognition The World Health Organisation (WHO), UNICEF, and the Red Cross therefore recommend the SODIS method as a way to treat drinking water in developing countries. “Solar disinfection is an example of another measure with proven health impact that requires little capital investment on the part of end-users, and is thus appropriate for the very poor.” Student-designed Solarball creates drinkable water. The Solarball is a student-designed device that creates clean drinking water through evaporation and condensation (All photos courtesy Monash University) Image Gallery (3 images) When he set out on a trip to Cambodia in 2008, Industrial Design student Jonathan Liow had no idea it was going to be a life-changing experience.
Upon seeing the poverty and poor living conditions in that country, however, he decided that he wanted to build things that could help people. After hearing about the need for cheap and effective water purification in Africa, he proceeded to create the Solarball for his graduate project at Australia's Monash University. Users start by pouring dirty water into the Solarball. Liow – who has since graduated from Monash – said that one of the main challenges in the design was "to make the device more efficient than other products available, without making it too complicated, expensive, or technical.

Currently on display in the ROCA Gallery, London Water. It’s something we often take for granted. However, 1 in 8 people in our world don’t have access to clean, drinkable water. This is the cause of nearly 80% of all sickness and disease in third world regions. The Solarball is a personal and portable water purification device, capable of producing potable water out of contaminated water.
The lower half of the Solarball is insulated by a pocket of air - allowing the dirty water inside to absorb and retain heat more efficiently.

The effect of soap distribution on diarrhoea: Nyamithuthu Refugee Camp. Communicable diseases in complex emergencies: impact and challenges : The Lancet.
Communicable diseases, alone or in combination with malnutrition, account for most deaths in complex emergencies. Factors promoting disease transmission interact synergistically leading to high incidence rates of diarrhoea, respiratory infection, malaria, and measles. This excess morbidity and mortality is avoidable as effective interventions are available. Adequate shelter, water, food, and sanitation linked to effective case management, immunisation, health education, and disease surveillance are crucial.
However, delivery mechanisms are often compromised by loss of health staff, damage to infrastructure, insecurity, and poor co-ordination. Copyright © 2004 Elsevier Ltd.

Recycled Plastic Bottle House Built in Nigeria. © Andreas Froese/ECOTEC Thousands of pieces of trash that would otherwise be clogging waterways and landfills in Nigeria have been turned into sturdy, and surprisingly attractive, construction materials in the village of Yelwa, where the country's first plastic-bottle house is drawing curious visitors and plenty of press.
"Hundreds of people -- including government officials and traditional leaders -- have been coming to see how the [house's] walls are built in the round architectural shape popular in northern Nigeria," the BBC reported this week. Stronger Than Conventional ConstructionThe bottles are actually filled with dry soil or construction waste, not sand (an "unnecessary expense"), John Haley of ECOTEC, the firm that is training local masons in the technique, told TreeHugger.com in an email.
They are then laid in rows like bricks and bound together with mud, producing a sturdy, well-insulated, and inexpensive three-room structure that is resistant to both bullets and earthquakes. Quenching the Thirst - How Packaged Drinking Water Has Become Big Business in Africa. Why is drinking water such a big deal? If drinking water seems ‘ordinary’ or ‘common’ to you, it is likely you may have been taking this precious resource for granted. For starters, water makes up nearly 70 percent of the human body. Everything inside us – blood, muscles, organs and bones – contain water and will not function at all in its absence.
In fact, a human being may last a whole month without any food, but without water, it would be a miracle if you last beyond a week. Of all our daily needs – food, shelter, electricity and health – safe drinking water is arguably the most important. Water is indeed a ‘drink or die’ affair. Before we explore the interesting business opportunities in the rest of this article, it is important that you understand exactly what we mean by ‘safe drinking water’. You may have noticed that water is very abundant on our planet; in fact, it makes up roughly 70 percent of the earth’s surface. 1. 2. 3. 4. 5. (photo credit: United Nations Environment Program) Plastic Bottles Trash Generates 26 000 Jobs. Plastic Bottles Trash Generates 26 000 Jobs Recycling PET, the plastic used to manufacture beverage bottles as well as many food containers, has helped generate almost 26 000 indirect jobs, and the plastics recycling industry can reduce poverty across South Africa and contribute to GDP growth.
This is the upbeat message from the CEO of PETCO, Cheri Scholtz, on the second day of the South African National Bottled Water Association’s Conference in Midrand, Gauteng. PETCO is the industry organisation responsible for PET recycling in South Africa. In a presentation entitled “PET Recycling in South Africa – Plastic Bottles are not Trash”, Scholtz informed delegates that PETCO and its recycling initiatives have become a global benchmark for extended producer responsibility because of its success to bale-by-bale, year-by-year, reduce the volume of post-consumer PET plastic in the waste stream.

Recycling heralded as the way to eliminate plastic waste ACCRA, 21 July 2004 (IRIN) - Drinking water in Ghana comes in plastic bags not bottles.
And these bags are the bane of Korkor Ocansey's life. Ocansey owns a fabric store in the business district of the capital Accra, and has had enough of the discarded plastic sachets which clog her gutters. "The water sachets are a menace," she told IRIN on Wednesday. "Even the slightest bit of rain directs the flow of water into the store. I have lost goods as a result of these choking sachets. The sooner we contain the situation, the better. " Luckily for Ocansey, help is at hand. This month the Ghanaian government launched a US$1.5 million war on the 270 tonnes of plastic waste generated each day by the capital's three million inhabitants.
Over the years plastics have replaced leaves, glass and metal as a cheaper, and more efficient means of packaging. Adjei-Darko painted a stark picture of what would happen without proper recycling. Rethinking plastics: Role of policies in resolving East Africa’s waste - Special Reports. At the Kampala Capital City Authority’s refuse dumpsite in Kiteezi, some 14 kilometres north of the CBD, men and women pick through the garbage alongside the ubiquitous marabou storks.
They are gathering plastic waste to sell to recyclers. Called “scavengers” in the local plastics industry, these men and women make Ush150 ($0.561) per kilogramme of plastic waste they sell to contract collectors. The collectors earn Ush700 ($0.262) for every kilogramme they deliver to recyclers. This business chain also includes washers and transporters.
This scene is replicated around the region, creating an industry that employs thousands of people. Estimates put the number at about 80,000 in the more than 260 plastics manufacturing industries in Kenya, Uganda and Tanzania as well as hundreds more who work in underground operations. But while this waste is a source of livelihood to some, to activists it is an environmental and health hazard. “The plastic used for water bottles is not easily recyclable. Search. Public Health in Emergencies. Oxfam is widely known for its public health work in emergencies. The rapid supply of clean water to populations displaced from their own homes is vital, and Oxfam has particular expertise in this area. For more on Oxfam's water, sanitation and hygiene promotion (WASH) work in both emergencies and long-term development please visit our WASH page.
Oxfam's role During emergencies, Oxfam's Public Health Engineers (PHEs) and Public Health Promoters (PHPs) work with communities to create an environment in which public health risks are reduced and the safety and dignity of emergency-affected communities is enhanced. Oxfam's public health humanitarian work focuses on: The provision of clean water Improved sanitation and vector control The promotion of activities essential for promoting health and a healthy environment The distribution of items essential for health and hygiene Oxfam adheres firmly to the minimum standards set out in the SPHERE charter.
What we do What we don't do. WASH. Oxfam aims to address the disparity in water and sanitation coverage that exists - nearly 800 million people lack access to water and 2.5 billion to sanitation. In 35 countries we are working on projects that integrate sustainable and local innovation to meet the needs of the poorest. Oxfam believes everyone including the most marginalised have a right to safe water and sanitation as a basic essential service, and advocates for development of pro-poor policies that eliminate inequality that underlie the water management policies that exacerbate water scarcity. Oxfam's approach to WASH In Oxfam terms, Water, Sanitation, and Hygiene Promotion (WASH) incorporates: Water: water supply for human consumption and household needs, as well as for crops and livestock needs where appropriate.
In addition to its disaster response mandate, Oxfam prioritises a preventative approach to public health, improving WASH conditions and consequentially addressing poverty reduction and quality of life. Latrine leaders in Dadaab refugee camp. At a camp in Haiti, families long for a new start – and land to call their own. For the 89 families crowded into tents on a strip of land in Gressier, an hour’s drive outside of Haiti’s capital of Port-au-Prince, uncertainty has become the daily constant in their lives.
Will they be forced off this rocky plot? Will they have to move again—for the fourth time since a massive earthquake destroyed their homes? Where else could they possibly go? “The biggest problem is the land,” says Clairin Webert, a sea of white tents billowing behind him. “Some people wake up at night crying because they don’t know what they’re going to do, where they’ll go.” 89 families live in tents at Merger camp, in Gressiers. As more than a million people remain homeless a year after the seven magnitude earthquake ravaged the capital and surrounding communities, access to land on which families can build new homes and start new lives—or even continue to camp in makeshift shelters—has become one of the most difficult challenges they face.
But for people like Yolande Chery, options are few. Emergencysanitationproject.wikispaces. Oxfam calls for innovative new ideas in toilet challenge | Press releases. Oxfam is challenging designers, manufacturers and inventors to develop new, innovative ideas for toilets that can be used in emergency situations and save lives in disasters across the world. The charity is offering the chance to get involved in their 'Design a Bog Day' in Oxford on 13 September and create the emergency sanitation kit of the future with grants totalling £80,000 available to further develop ideas after the event. Over 70 years, Oxfam has become a world authority on emergency water and sanitation. When disasters hit, toilets and taps help prevent the spread of disease and can save lives, fast. Oxfam needs simple sanitation structures which can be flat-packed and flown across the world quickly and easily. But right now there's a real shortage of this functional, low-cost equipment.
Angus McBride, Oxfam's Emergency Sanitation Researcher said: "Oxfam need brilliant ideas and industry expertise for our 'Design a Bog Day'. Oxfam are looking for innovative designs in four areas: Tippy Tap, a cheaper, more hygienic, more durable hand washing station. | Peace Corps Burkina Faso. Handwash Habits. BC-Overview. Handwashing.
