Community at the Heart of Water Access – Ouled Ahmed, Tunisia

Every morning in the village of Ouled Ahmed, in Tunisia’s Kasserine Governorate, clean drinking water now flows directly into family homes. For one young boy, it means something simple yet transformative: turning on a tap and drinking safe water without fear. What was once a daily struggle has become a quiet certainty, reshaping everyday life in this rural, drought-prone region.

WASH Emergency Response – Matthew Hurricane – Haiti

When Hurricane Matthew struck Haiti in 2016, it left entire communities in the Port-Salut region facing severe disruption, particularly in access to clean water and sanitation. In the immediate aftermath of the disaster, time was critical. Rapid action was needed to prevent further hardship and protect public health. Thanks to swift cross-border coordination, emergency WASH support was rapidly deployed from the Dominican Republic. Spare parts, essential equipment, and a wide range of technical materials were mobilized and delivered to affected areas, enabling the quick repair and installation of water and sanitation systems. This logistical lifeline played a decisive role in

Hydrogeological Support – Rural Water Programme – Tunisia

15.06.2026

The engagement began with an evaluation of the project in 2013, which led to the recommendation for a complete strategic realignment. Following this assessment, comprehensive managerial and technical support was provided over a five-year period (2013–2017) to support the restructured programme. A backstopping mandate was awarded to DROPSTONE to ensure the technical and institutional support of the “Projet Eau Kasserine” (PEK). This included the implementation of 15 large-scale rural drinking water and irrigation projects, supported by specialized hydrogeological expertise for groundwater monitoring and the sustainable use of natural resources. The programme also placed strong emphasis on capacity building, with training
