Arid Lands Newsletter
An article entitled, “Making the most of a scarce resource: Solar disinfection of drinking water in the arid zone of western Rajasthan.” Rajasthan is the largest state in India, occupying just over 10 percent of the total area of the country. Exposure to waterborne infectious diseases is a significant issue in rural India, where almost three-quarters of the population lack access to a reliable source of safe water and where diarrhea and similar diseases linked to the consumption of water contaminated with pathogenic microbes represents a continuous threat to the local people. This is especially so in arid areas such as western Rajasthan, where treated water is a scarce resource.

Energy Industry
An article from Energy Resource entitled “Providing Solar, Water Filtration Technology for Clean-Water Initiative Launched by Dynoil.” GE is supplying its ecomagination-certified solar energy modules and water filtration technology for a new initiative launched by Dynoil aimed at increasing the availability of clean drinking water in rural areas of India and in other developing countries of Southeast Asia and Africa.

EnerSol
Currently, 23 percent of rural Hondurans and 22 percent of rural Dominicans do not have convenient access to a clean and reliable water source. As a result, many suffer from malnutrition, which blocks physical and intellectual development and makes them more susceptible to potentially fatal infectious diseases such as cholera or typhoid.
In 1995 Enersol implemented two pilot renewable energy-powered community water systems. Based upon this pilot model project, Enersol developed a total of 17 AguaSol Projects: 13 in the Dominican Republic followed by four in Honduras.

Faith In Action
Faith in Action International assists communities in educating, training, and improving their water supplies by capping springs, constructing rainwater reservoirs, installing solar water filters and construction and installation of bio-sand water filters.

Flutrackers
The Solar Water Disinfection (SODIS) process is a simple technology used to improve the microbiological quality of drinking water. SODIS uses solar radiation to destroy pathogenic microorganisms which cause waterborne diseases. This site has illustrated step-by-step guidelines for using SODIS.

IDRC
IDRC is a Canadian Crown corporation that works in close collaboration with researchers from the developing world in their search for the means to build healthier, more equitable, and more prosperous societies. This particular page is an article entitled “Water Disinfection Using Solar Radiation.”

Kenmar Foundation
A well-documented web site on SODIS. The web site is maintained as a public resource by The Kenmar Foundation. The foundation provides support to Canadian-based charities wanting to carry out solar water disinfection work in developing nations. Their mission is to eliminate suffering caused by the consumption of contaminated water. In particular, the foundation was formed to fund, design, promote, teach, and assist in the implementation and entrenchment of the practice of Solar Water Disinfection in disaffected regions of the world.
Their target is the poorest of the poor, the marginalized in any nation, and those often beyond the effective reach of government or charitable organizations. Their primary focus is the inhabitants of rural villages and city slums in the developing world.

Sandec
Sandec is the Department of Water and Sanitation in Developing Countries at the Swiss Federal Institute of Aquatic Science and Technology.
SEMID-EMWIS Euro-Mediterranean Information System
The study is entitled “Solar Water Disinfection—A Water Treatment Process Used at Household Level.”
The aim of the SODIS WATER project is to demonstrate that solar disinfection of drinking water is an effective intervention against a range of waterborne diarrheal diseases at household level and as emergency relief in the aftermath of natural or man-made disasters.

SODIS
This site is maintained by EAWAG (the Swiss Federal Institute for Environmental Science and Technology) and SANDEC (EAWAG’s Department of Water and Sanitation in Developing Countries). They have developed and tested the Solar Water Disinfection Process (SODIS). This is a simple, low-cost technology with a great potential to improve the health of those still without access to safe drinking water.

SODIS Africa Net
AQUACARE and its three partner organizations (Tam-Tam Mobile, Sarkan Zoumountsi and Groupe PESSAF) are implementing a Solar Water Disinfection (SODIS) project to introduce this simple, inexpensive and attractive household water treatment method in slum areas of Yaoundé, Cameroon, Central Africa. The main objective of this project is to improve the access of the poorest populations of Yaoundé to safe drinking water by integrating the method of SODIS in their daily activities.

Solar Liberty Foundation
Solar Liberty Foundation is dedicated to assisting people in rural areas of developing nations with renewable energy resources. The goal at Solar Liberty Foundation is to harness the power of the sun to provide people in need with solar electrification, solar water filtration, and solar cookers.
Survival Topics
This article details using SODIS, a water treatment system, using two readily available materials: sunlight and plastic PET bottles.

UNICEF
This study was originally published by UNICEF. Entitled, “Solar Disinfection of Drinking Water and Oral Rehydration Solutions—Guidelines for Household Application in Developing Countries,” it was produced by the Department of Environmental Health, Faculty of Health Science at the American University of Beirut.

Water Sch2ool
The science of the SODIS system is proven with over 20 years of research (www.sodis.ch). The water SCH2OOL has taken this technology and developed a successful and sustainable implementation program that operates through the women and children of target communities. The FAQ has many helpful questions and answers.
Water Secrets Blog
This is an article entitled, “Solar Water Disinfecting Tarpaulin Produces Potable Water.” Eric Olson, a San Francisco architect, has invented the Solar Water Disinfecting Tarp, which he believes could help eradicate the problem of polluted water, which the World Health Organization estimates claims over 1.5 million lives every year. Not only does it purify water, up to 20 liters, it also makes it more portable in large quantities.
