Mauritius Reservoirs at 49.6% Capacity as Suppliers Demand Subsidy Review
Mauritius's main water reservoirs stood at just 49.6% full on 5 November 2026, with Mare-aux-Vacoas at 33% and La Nicolière at 43.7%.
Mauritius is facing a concerning water storage situation, with the island's principal reservoirs collectively filled to only 49.6% of their total capacity as of 5 November 2026, according to figures noted by the Cabinet of Ministers at its weekly meeting on Friday.
The two most significant reservoirs on the island are showing particularly low levels. Mare-aux-Vacoas, located in the central highlands and historically the largest reservoir in Mauritius, stood at just 33%. La Nicolière, situated in the north of the island and a key water source for a large portion of the population, was at 43.7%. Both figures are well below what would be considered comfortable for this period of the year.
The Ministry of Energy and Public Utilities, the government body responsible for overseeing water management and supply infrastructure in Mauritius, is said to be closely monitoring the situation.
Alongside the low reservoir levels, water suppliers are pressing the government for a revision of the subsidy framework that governs the sector. The current subsidy structure affects how water services are priced and funded, and suppliers appear to be arguing that existing arrangements no longer reflect the operational costs of maintaining and distributing water across the island.
What this means: For everyday Mauritians, low reservoir levels in early November raise questions about water availability heading into the summer months, when demand typically rises alongside higher temperatures. If levels do not recover sufficiently before the dry season ends, authorities may be forced to introduce water rationing measures or restrictions in certain areas. The push by suppliers for a subsidy revision also hints at potential changes to how water services are financed, which could ultimately affect household bills or the level of government spending directed at the sector. Residents and businesses that rely on consistent water supply, particularly in the northern and central regions served by La Nicolière and Mare-aux-Vacoas, should follow updates from the Central Water Authority, the public body that manages water distribution in Mauritius.
The Cabinet's acknowledgement of the reservoir situation suggests the issue is being treated as a matter of national importance, though no emergency measures have been announced at this stage.
