WHAT ARE WE GOING TO DO IN MUKONO?

In our latest project ‘Water for Mukono' we will realize access to clean drinking water for approximately 3.300 people. This will be achieved through rainwater harvesting and the construction of biosand water filters.
In areas where there is no surface water, where groundwater is too deep or inaccessible due to hard surface conditions, or where it is too salty, acidic or otherwise unpleasant or unfit to drink, another source must be found. In areas that have regular rainfall, the most appropriate alternative is the collection of rainwater, called ‘rainwater harvesting’.
Rainwater can be collected from most roofs, tiled roofs (or roofs sheeted with steel) are preferable, since they are the easiest to use and give the cleanest water. The gutters drain through a down-pipe, which discharges into a storage tank.
In addition to the rainwater tanks, 32 biosand water filters will be constructed. Due to their effectiveness, ease of use, and lack of recurring costs, biosand filters are often considered appropriate technology in developing countries.
A biosand filter (BSF) is a point-of-use water treatment system adapted from traditional slow sand filters. Biosand filters remove pathogens and suspended solids from water through a combination of biological and physical processes that take place in a sand column covered with a biofilm.
