Drought in Mauritius: Mare-aux-Vacoas Reservoir Hits Worrying Lows

Mauritius is in the grip of a prolonged drought, and nowhere is the impact more visible than at Mare-aux-Vacoas, the island's largest reservoir, located in the central highlands near Vacoas-Phoenix. Water levels there have fallen to worrying lows after months of below-average rainfall, raising serious concerns among authorities and residents alike.

Several parts of the island are already experiencing rationed water distribution, with households and businesses facing reduced or intermittent supply. The situation reflects a broader pattern of insufficient rainfall that has stretched over recent months, leaving the country's water storage infrastructure under considerable strain.

To compensate for the shortfall, the authorities have stepped up the activation of additional boreholes, which draw groundwater to supplement the supply from surface reservoirs. While this provides some relief, it is not a long-term substitute for sustained rainfall replenishing the island's main water stores.

Forecasts do point to heavier showers in the coming period, which would be welcome news. However, water management experts caution that a few isolated bouts of rain are unlikely to be enough to fully restore reservoir levels after such an extended dry spell. Meaningful recovery will require consistent and significant rainfall over a sustained period.

In the meantime, the public is being urged to use water carefully and responsibly. Simple actions can make a real difference at times like this: fixing household leaks promptly, avoiding unnecessary garden watering, cutting back on car washing, and being mindful of water use in kitchens and bathrooms.

Mare-aux-Vacoas has a total capacity of around 27 million cubic metres and is the cornerstone of Mauritius's drinking water supply, managed by the Central Water Authority (CWA). It serves a large portion of the population, which makes its current state a matter of national concern rather than a local inconvenience.

What this means: If you live in Mauritius, you may already be experiencing scheduled cuts or reduced water pressure in your area. The situation at Mare-aux-Vacoas signals that restrictions could continue or even intensify if rainfall does not arrive in meaningful quantities soon. Residents are encouraged to store water sensibly during periods when supply is available, repair any leaks without delay, and avoid all non-essential uses until the reservoir recovers. Businesses, hotels and agricultural operations that rely on large volumes of water should also review their consumption practices in light of the current shortage.
