| Summary: | Today 1 billion people in the world lack safe drinking water and 2.6 billion people do not have access to basic sanitation (WSP, 2006). This causes large health- and contamination problems, especially in urban areas. Due to UN Habitat (2003) the world’s urban population will increase from 3 to 5 billions within 20 years. Many developing countries do not have an adequate municipal drinking-water service and it is common that the water is provided by small water communities. The work is often carried out by non-professionals and control of the drinking-water quality is uncommon. To simplify the work with drinking water control WHO has developed guidelines for water monitoring adapted to small water communities. Since the early 1990’s the Swedish International Development Agency (SIDA) has been working with the concept of ecological sanitation (eco-san) to advance in the development of safe, robust and economical sanitary solutions. The challenge is to create systems that consume little or no water, minimize the contamination risk and allows recycling of nutrients to agriculture. In Bolivia, South America’s second poorest country, diseases caused by lack of safe drinking water and proper sanitation are common. The health situation has improved the last 30 years as more people have gained access to improved drinking water (85%) and sanitation (46%). The Bolivian company Agua Tuya has been working with drinking water systems in peri-urban areas of Cochabamba, Bolivia, for 15 years. During the last years the demand for sanitation has increased and to meet that demand cooperation with the research organization EcoSanRes has been established. In a pilot project 20 urine-diverting toilets will be built in Challacaba, Cochabamba. Agua Tuya also plans to open a Resource Center that among other things will offer a monitoring program for small-scale water distribution. This Master’s thesis at Luleå University of Technology will contribute with tools to improved drinking water monitoring and sanitation in peri-urban areas. It ...
