Water scarcity intensifies in Tunisia and Mauritius

Tunisia and Mauritius are facing severe water security challenges driven by aging infrastructure and persistent drought conditions.

In Tunisia, the national water distribution network is under significant strain. Approximately 62% of the pipes managed by the Société Nationale d’Exploitation et de Distribution des Eaux (SONEDE) are outdated, with some sections exceeding 70 years of age. This deterioration leads to massive resource loss, with network efficiency stagnating at 75%, meaning roughly 25% of potable water is lost to leaks. Some expert assessments suggest losses could reach as high as 50%, resulting in frequent service interruptions.

In Mauritius, the Mare-Aux-Vacoas reservoir has dropped to 40% capacity, a sharp decline from over 80% during the same period last year. The Central Water Authority (ACE) has described the situation as ‘very alarming.’ The depletion is attributed to persistent drought and the transition from La Niña to El Niño. Consequently, strict conservation measures are in place, including bans on vehicle washing and limited agricultural irrigation. Some regions are already experiencing scheduled water cuts, limiting household supply to specific daily windows.
