Mauritius Water Crisis: Up to 65% Lost in Leaking Pipes, Says Reform Party

Mauritius is grappling with a serious water crisis, and the opposition Reform Party is pointing to a startling statistic at the heart of the problem: up to 65 percent of treated water is being lost before it ever reaches a household tap, due to leaks and failures in the island's ageing pipe network.

The Reform Party raised this figure publicly, arguing that the water shortage affecting thousands of Mauritian households is not simply a matter of insufficient rainfall or reservoir levels. According to the party, the infrastructure used to distribute water across the island is so degraded that a significant majority of what is treated and pumped into the system simply never arrives at its destination.

This is a striking claim. For context, the Central Water Authority, known as the CWA, is the state body responsible for water production, treatment and distribution in Mauritius. Water losses in distribution networks, often called non-revenue water in the industry, are a known problem in many countries, but a figure approaching 65 percent would place Mauritius among the worst-performing systems in the world. The international benchmark for a well-managed utility is typically below 20 percent.

The Reform Party has used these figures to call for urgent investment in pipe replacement and infrastructure modernisation, arguing that no amount of new water sources will solve the crisis if the distribution system continues to haemorrhage supply at this rate.

The water crisis in Mauritius has been building for some time. Residents in many parts of the island have faced intermittent supply, with some areas receiving water for only a few hours a day or on rotating schedules. The government has already announced plans to requisition between 15 and 20 new boreholes to boost supply, but critics argue that tackling demand-side shortfalls without fixing the distribution network is treating symptoms rather than causes.

Pipe infrastructure in Mauritius includes sections that are decades old, and the cost of replacing them across a national network is substantial. The Reform Party's intervention brings renewed political pressure on the government and the CWA to prioritise this work.

What this means for residents and the broader debate: if the 65 percent loss figure is accurate or even close to accurate, it means Mauritius is spending significant public resources treating water that never benefits anyone. Every litre lost to leaking pipes represents money spent on energy, chemicals and labour that produces no return. Fixing the pipes would, in theory, dramatically increase effective water availability without needing to find a single additional drop of raw water. For households currently receiving rationed supply, that argument carries considerable weight.

The government has not yet publicly responded to the Reform Party's specific figures. The CWA has acknowledged infrastructure challenges in the past but has not confirmed the 65 percent loss rate.
