2. RISE CHINA: ORGANIZATIONAL PROFILE Affiliated with Tsinghua University, School of Environment Over 20 members International and Chinese Student collaboration Majority of members are graduate students from School of Environmental Engineering Goal : Apply our knowledge and skills for sustainable development in rural areas Method of knowledge and technology transfer (training)

3. FIRST PROJECT: WATER SAFETY IN RURAL CHINA Did you know that in rural areas of China: 40% of potable water was stated to be unhealthy? over 300 million rural Chinese residents still have no access to safe drinking water? drinking water contaminated with levels of animal and human excreta can exceed maximum permissible levels by as much as 86%? There are technologies available which are SIMPLE and AFFORDABLE!

4. BIOSAND FILTERS (BSF): THE ALTERNATIVE Centre for Affordable Water and Sanitation Technologies (CAWST) <www.cawst.org Manz Water Info

5. OUR APPROACH: TRAINING THE TRAINERS 1 st Develop a comprehensive training program for trainers BSF construction and maintenance Basic skills of how to manage an enterprise/project 2 nd Train students and NPOs (project dissemination) We do not just SUGGEST them a Solution, We COACH them how to make it! This promotes self-sustainability!
