Objective for the 2026 funding round
Put a ceramic or bio-sand filter in 1,500 homes and train each household to use and clean it, cutting diarrhoea among young children.
Who it reaches: Families who drink from rivers, ponds or unprotected wells and can't boil water every day.
Target$61,655
Funding for this cause closes in
From $80: household water filters for two families of six.
The need
Where boreholes are not possible yet, families drink what they can collect. A ceramic or bio-sand filter removes most bacteria and cuts diarrhoeal disease, a leading killer of young children.
Why give to this cause
- A household filter is one of the lowest-cost ways to make water safe to drink.
- Families are trained to use and clean their filters, and follow-up visits check they are still in use.
- Where a borehole is years away, a filter protects a family's health right now.

How we do it
- 1
Community health workers select households with young children and no safe source.
- 2
Families are trained to use and clean the filter, and sign for it.
- 3
Follow-up visits at one and six months check it is in use.
- 4
Diarrhoea cases at the local clinic are tracked before and after.
The impact your gift will have
- Families drink clean water every day from a filter in their own home.
- Fewer children fall ill with diarrhoea, one of the most common and preventable causes of child illness.
- Households spend less on medicine and on fuel for boiling water.

DonateQuestions donors ask
How much does it cost to build a water well in Africa?
A borehole costs several thousand dollars to drill, test and equip, depending on depth and ground conditions. You don't need to fund a whole well: every gift is pooled toward the next borehole, and the Wells and boreholes page shows what each amount buys.

How do you make sure water wells keep working?
Every water point has a trained local committee and a repair fund, and we check that it is still working 12 months after it is built.
