Access to safe drinking water in schools
Tanaff, Senegal
In the Tanaff 1 and 2 elementary schools, in southern Senegal, over a thousand children faced the lack of safe drinking water every day. The school taps were connected to an unstable and contaminated water network, supplied by a water tower that operated only for a few hours a day. Drinking that water meant exposing oneself to serious health risks, in a context where even a simple infection can become life-threatening.
The project rehabilitated the school wells with solar-powered systems, 1,000-liter tanks, and advanced reverse osmosis filtration, ensuring pure water every day for over 1,150 students. The new plants not only improve children's health but also provide a valuable resource for neighborhood families, especially pregnant women and newborns, thus helping reduce waterborne diseases, malnutrition, and child mortality.

In Tanaff, in southern Senegal, thousands of people face a daily lack of safe drinking water. The absence of reliable systems forced entire families to collect water from contaminated sources, posing serious health risks, especially for children and pregnant women. To address this emergency, Balouo Salo built an innovative water purification plant, fully powered by solar energy, capable of providing filtered, sterilized, and free water to over 5,000 people.
The project is a concrete response to water insecurity, but also a sign of hope and dignity. In addition to improving hygiene and public health, the infrastructure helps reduce the time women spend fetching water, thereby promoting education, productivity, and social participation. Resulting from strong collaboration between local authorities, international partners, and donors, the initiative fosters human and environmental development while integrating with local culture.
The system provides safe water to over 3,500 direct beneficiaries and about 5,000 indirect beneficiaries in surrounding villages, significantly helping to reduce the spread of waterborne diseases.
Where it is located
The Tanaff plant stands out for its sustainable, efficient, and replicable technological approach. The system is based on deep drilling that reaches a safe and stable aquifer. A 7m³/h submersible pump, powered by a 3kW photovoltaic system, allows continuous water extraction. Additionally, a second 10kW solar system (donated by La Solution Solaire) ensures power supply for treatment systems.
The purification systems
The water is filtered through a system , consisting of iron removal filters, carbon filters, microfilters, and UV sterilization. Up to 1,000 liters of drinking water are treated every hour, in line with WHO standards. . The filtered water is stored in tanks and distributed through 8 fountains placed in the most accessible locations for the population.
