In many African countries, children are expected to bring water to school for cooking, cleaning and drinking. Collecting this water steals hours from every child’s school day. Sometimes, during periods of drought, collecting water might take a whole day. This means days of school missed and long distances travelled in the midday heat.

That's why Excellent Development supports self-help groups to build water tanks at their local schools.

Making water available at schools means children can spend more time learning. Having a free and available water supply also keeps children hydrated - helping them to make the most out of each school day.

Water tanks store rainwater collected from school roofs. They last at least 25 years and require little maintenance. Each one provides enough water and opportunity for generations of children.
