Mauritius Water Crisis: 50 Years of Plans, Same Old Problems

Mauritius has been drawing up water management plans for more than half a century. Yet the island keeps returning to the same crisis point — rationing, leaking pipes, drought-hit reservoirs, and frustrated households. So what has gone wrong? **A long history of planning, short on delivery** Since independence, Mauritius has commissioned multiple national water strategies, feasibility studies, and infrastructure masterplans. International donors, government agencies, and consultants have all weighed in over the decades. The Central Water Authority (CWA), the state body responsible for water production and distribution, has been at the centre of these efforts — but critics argue that implementation has repeatedly fallen short of ambition. The core problems have remained stubbornly consistent: an ageing pipe network that loses an estimated 40–50% of treated water through leaks before it ever reaches a tap; uneven distribution across the island, with the north and west traditionally underserved; and a heavy dependence on rainfall to fill reservoirs, leaving supply vulnerable to dry spells. **The reservoir warning sign** The stress on the system is visible in real time. Mare-aux-Vacoas, the island's largest reservoir and the backbone of domestic water supply in the central and southern regions, recently dropped to just 36.6% capacity — compared to 89.6% at the same point a year earlier. That kind of year-on-year swing illustrates exactly how exposed Mauritius remains to rainfall variability, even after 50-plus years of planning. **Why do the crises keep coming back?** Experts and civil society groups point to several structural reasons. First, capital investment in replacing old pipes has been chronically underfunded relative to the scale of the problem. Second, water tariffs have historically been kept low for political reasons, limiting the CWA's ability to generate revenue for reinvestment. Third, climate change is making rainfall patterns less predictable, stretching a system already running close to its limits. There is also the question of institutional continuity. With each change of government, water policy priorities can shift, long-term projects lose momentum, and freshly commissioned studies effectively restart the clock. **What is being proposed now?** Current discussions include accelerating desalination capacity — an option long resisted due to high energy costs but increasingly seen as unavoidable — alongside leak-reduction programmes and the construction of additional storage infrastructure. The government has also flagged the need for better demand management and public awareness around water use. **What this means for residents** For ordinary Mauritians, the practical consequence is continued intermittent supply, particularly in drier months or during extended dry spells. Businesses, hotels, and agriculture — all major water consumers — also face uncertainty. Until the structural gap between plan and implementation is closed, the cycle of crisis, report, and repeat looks set to continue. Source: Le Defi Media
