The document discusses the water supply situation in Sri Lanka, noting that 40% of the population has organized access to water, while 59.4% relies on various alternative sources, including unprotected ones. It highlights common impurities in drinking water, the importance of purification methods, and outlines various filtration technologies and their effectiveness in removing contaminants like arsenic and bacteria. Additionally, it includes a proposed budget and schedule for the development of a domestic water purifier project.
