Bio-sand water filter, Uganda


Over 9 million men, women and children in Uganda do not have access to clean, safe drinking water. Children die every day from preventable diseases caused by contaminated water and improper sanitation and hygiene. You can help provide the gift of clean water today by purchasing a bio-sand water filter for a family in need. These filters remove up to 99% of pathogens and parasites without the need for chemical treatment or boiling, reducing water-borne diseases. The reduced charcoal use also means that families have more money to spend on other essentials and, with fewer trees needing to be cut down, habitats are protected.


Across Uganda, approximately 25% of the population still lacks access to clean, safe drinking-water[1]. This means that every day, around 9 million people are risking their lives and health by drinking from contaminated water sources. Bio-sand water filters (BSFs) provide a cheap and simple solution and can have dramatic health, economic and social benefits. By passing water through layers of sand and sediment, they are able to remove up to 100% of worms and protozoa, up to 98.5% of bacteria and 70-99% of viruses.

Previous BSF recipients report a reduction in infectious diseases such as cholera, dysentery and diarrhoea, fewer work days lost due to illness and caring for the sick, and less time lost in fetching and boiling water. Many previously spent an hour each day on boiling their water (15 days per year), which they can now use more productively on other activities. Mothers have also noticed a positive impact in the area of education – children learn better when they go to school properly hydrated.

Each filter can be shared by several households. One BSF therefore provides clean water for around 12 people per day and saves the community an estimated £200 in charcoal costs and medical fees. The reduced fuel use also means that fewer trees need to be cut down, which protects habitats and keeps carbon locked up.

A Rocha Uganda has been implementing the bio-sand water filter programme since 2008, in both urban and rural communities. Every BSF is carefully monitored on an annual basis, to gather feedback and ensure that they are being correctly used and maintained.
