we need to install a collection tank for the raw water available. Install filters ranging from primary sand filter, magna sand filter, Softener filter and an activated carbon filter. In the case of the softener we use raisin and this is activated using common salt so as to reduce the hardness. The Activated carbon filter provides a large surface area for filtration thus giving rise to clear potable water. As a mechanical ...more »
The Lifestraw is a small cigar-shaped tube packed with some truly innovative engineering. This clever design purifies water from potential pathogens like typhoid, cholera, dysentery and diarrhea – all before they reach your lips. The Lifestraw is an inexpensive way to deliver potable water to those in need, and it is considered an icon of humanitarian product design – it was included in Cooper Hewitt’s Design for the ...more »
Water Sources in Africa and particularly in Uganda are; 1. Clear flowing water and 2. Lakes, ponds and rivers Clear flowing water coming from somewhere without people, manmade things or an obvious sign of pollution is best. Lakes, ponds and rivers are less ideal. The first two are stagnant, which may mean increased levels of bacteria and other gross things, while large rivers are typically full of pollution. Not forgetting ...more »
Using nature's genius and systems thinking to achieve zero waste within informal settlements. We have used the principles and genius of nature to develop an effective solution that addresses the impacts of stormwater and solid waste from informal settlements; piloted in two projects for the Berg River Improvement Plan in the Western Cape. The end goal is to achieve a zero-waste scenario, ...more »

considering the economy , environment and availability of water and other resources in south Africa this process will be the most suitable method of filtering water in almost all the areas of Africa
Slow Sand Filtration (SSF) technology has been used to treat the drinking water of many European and American cities over the last 200 years. Introduction of slow sand filtration to American cities in the early 20th century was the primary factor responsible for the massive declines in infant mortality and waterborne disease. The HydrAid Biosand Water Filter is the inspiration that is the solution. Performance, life saving ...more »
Slow sand filtration Slow sand filtration has the advantage of working on an entire community's water source, not just individual households. Practical Action put together a technical manual for slow sand filtration systems, a complete guide to their construction and maintenance. Follow the link above to see the manual. A slow sand filtration system is a combination of several parts: water storage tanks, an aerator, ...more »
Reeds and water plants etc are good filtrators of river water, fence areas around the catchment areas to prevent animals polluting the water and collect filtered water in tanks.
