Editorial<\/u><\/span><\/p>\n

Climate change is making rainfall less predictable, while population needs, economic activity and the demand for reliable services continue to place pressure on our water resources. These are real challenges. But nature alone cannot explain why so much treated water is lost before reaching consumers, why essential infrastructure projects take so long to materialise, or why the country repeatedly appears unprepared when reservoirs fall to worrying levels.<\/span><\/p>\n

Singapore offers valuable lessons. Despite its limited land area and scarce natural water resources, it has developed one of the world’s most carefully planned water-management systems. Mauritius cannot simply reproduce the Singaporean model: the two countries differ in geography, population, economic structure and available resources. However, Singapore demonstrates that water security is not merely a question of rainfall. It is also a question of political vision, institutional coordination, investment, technology and public accountability.<\/span><\/p>\n

A crisis that exposes deeper weaknesses<\/strong><\/span><\/p>\n

The current situation illustrates the scale of the challenge. On 8 October 2026, the Government reported that the country\u2019s main reservoirs were only 57.1% full, compared with 87.4% at the same time in 2025. Mare-aux-Vacoas, a critical source of supply for the Plaines Wilhems region, stood at just 35.7%. Production at the La Marie Water Treatment Plant had fallen from approximately 110,000 to 56,000 cubic metres a day. Emergency measures, including additional boreholes, river filtration units and water tankers, were being deployed to address the shortfall.<\/span><\/p>\n

These interventions are necessary, but they are responses to an immediate emergency. The more important question is why a country with considerable water resources continues to face recurring shortages. Although drought is certainly a factor, it may not fully account for the entire situation.<\/span><\/p>\n

The National Audit Office\u2019s December 2025 performance audit on sustainable water resources management provides a sobering assessment. In 2024, non-revenue water averaged around 60% nationally, with considerable variation between supply zones. This means that a substantial proportion of the water entering the distribution system generated no revenue for the Central Water Authority (CWA). The category includes physical leakage, as well as water that is delivered but not billed and other accounting losses; it should not be interpreted as meaning that every litre is leaking from a pipe.<\/span><\/p>\n

Nevertheless, the figures are alarming. In the 2024\u201325 financial year, approximately 195 million cubic metres of water were classified as non-revenue water. The audit estimated that defective pipelines contributed to around Rs 3.6 billion in combined unrecovered production and distribution costs and notional revenue losses during that year. According to the audit report, ageing pipes, inadequate maintenance, delays in replacement programmes and weaknesses in implementation have all contributed to the problem. This is not merely a technical failure. It represents a failure to protect a valuable public resource. Every cubic metre lost through a leaking pipe is water that has been treated, often at considerable cost, but may never reach a household, school, hospital or business.<\/span><\/p>\n

The audit also raises concerns about the pace of infrastructure renewal and the effectiveness of capital spending. Mauritius has discussed water shortages and the need for better infrastructure for decades. Yet successive plans have not eliminated the underlying weaknesses. Announcing another committee, plan or emergency intervention will not be enough unless there is a clear timetable, adequate technical capacity and public reporting on results.<\/span><\/p>\n

Singapore\u2019s Four National Taps<\/strong><\/span><\/p>\n

Singapore\u2019s experience, as documented in numerous research papers online, is instructive precisely because it began from a position of severe vulnerability. With limited land to collect and store rainwater, the city-state could not rely on natural resources alone. Instead, it developed a long-term strategy built around what it calls the \u201cFour National Taps\u201d: water collected from local catchments, imported water, recycled water known as NEWater, and desalinated seawater.<\/span><\/p>\n

Today, around two-thirds of Singapore\u2019s land surface serves as a water catchment. Rainwater is channelled through an extensive network of drains and canals into 17 reservoirs before being treated. The country has also invested in advanced wastewater treatment, operating five desalination plants alongside its NEWater factories\u2014specialized water-reclamation facilities managed by Singapore\u2019s national water agency, PUB. These sources reduce its dependence on rainfall and provide greater resilience when dry conditions persist.<\/span><\/p>\n

The lesson here is not that Mauritius should adopt Singapore\u2019s model wholesale. Singapore\u2019s dense urban landscape, industrial demand, financial resources and water constraints differ from ours. Nor is its system without challenges: desalination is energy-intensive, and growing demand requires continued investment. The deeper lesson is that Singapore treats water security as a national priority requiring sustained action across generations. It does not wait for reservoirs to fall before thinking about the next decade. Infrastructure, technology, conservation, research and public education form part of a continuing strategy rather than a series of disconnected emergency responses.<\/span><\/p>\n

Mauritius needs that same discipline. Political leaders must recognise that water infrastructure cannot be planned around electoral cycles. Reservoirs, treatment plants and distribution networks take years to develop, and their benefits may be enjoyed by governments that did not initiate them. That should encourage continuity, not discourage investment.<\/span><\/p>\n

Fix the leaks before chasing every new source<\/strong><\/span><\/p>\n

The first priority for Mauritius should be to reduce losses from the existing network. It makes little sense to invest heavily in producing additional water while a large proportion of treated supplies fails to generate revenue or reach intended users.<\/span><\/p>\n

A national programme should establish measurable annual targets for reducing non-revenue water, supported by district-level data and independent verification. Singapore\u2019s reported non-revenue water level of around 4% in the 2018 international comparison cited by Mauritius\u2019s National Audit Office shows what disciplined network management can achieve, although differences in systems and measurement must be taken into account.<\/span><\/p>\n

The second priority is to capture and store more of the rainfall that the country receives. Better catchment management, protection of watersheds, restoration of degraded areas and investment in storage could improve resilience. The possibility of connecting reservoirs or transferring water between supply zones should also be assessed where technically, environmentally and financially feasible. Emergency planning must account for the fact that rainfall does not necessarily occur where and when it is most needed.<\/span><\/p>\n

The third priority is to diversify supply. Singapore\u2019s experience with recycled water and desalination deserves serious study. Mauritius could expand the use of treated wastewater for irrigation, landscaping and suitable industrial purposes, reducing competition for drinking-quality water. Desalination could provide an additional source in locations where it is justified, particularly during prolonged droughts.<\/span><\/p>\n

But neither technology should be presented as a magic solution. Desalination requires substantial energy and investment, while wastewater reuse demands rigorous treatment, monitoring and public confidence. Each proposal needs a transparent assessment of cost, environmental impact and long-term value. Experts are of the view that reducing leakage and improving efficiency may offer better returns than immediately committing to expensive new supply infrastructure.<\/span><\/p>\n

Water security requires public accountability<\/strong><\/span><\/p>\n

Singapore also demonstrates the value of integrated management. Its national water agency, PUB, oversees water supply, used-water reclamation and stormwater management within a coordinated framework. Mauritius should examine whether its own institutional arrangements allow the CWA, the Wastewater Management Authority, the relevant ministries and other agencies to plan and act effectively together.<\/span><\/p>\n

This does not automatically mean merging institutions. It means clarifying responsibilities, improving data-sharing and ensuring that one authority is accountable for delivering an agreed national water-security plan. Major projects should have published milestones, realistic budgets and explanations whenever deadlines are missed.<\/span><\/p>\n

The public, too, has a role. Water conservation should become part of everyday life, supported by public education, efficient appliances, rainwater harvesting where appropriate and incentives for businesses to recycle water. But citizens cannot be expected to shoulder the burden alone. Appeals to save water ring hollow when households experience prolonged interruptions while basic infrastructure problems remain unresolved.<\/span><\/p>\n

Tariffs and subsidies also require careful consideration. Water must be financially sustainable, but access to an essential resource must remain affordable. Any changes to pricing should be accompanied by clear service improvements and safeguards for vulnerable households.<\/span><\/p>\n

From recurring crisis to lasting reform<\/strong><\/span><\/p>\n

Mauritius does not lack water alone; it lacks sufficient resilience in the way water is collected, stored, treated, distributed and managed. Climate change makes reform more urgent. Singapore\u2019s achievement was not built in a year, nor can Mauritius replicate it overnight. But the principles are transferable: plan for the long term, diversify supply, invest in technology, conserve resources, maintain infrastructure and measure performance openly. A country that aspires to higher living standards and a more productive economy cannot afford to treat reliable water supply as an occasional emergency.<\/span><\/p>\n

The next rainy season may replenish our reservoirs. It will not, by itself, repair ageing pipes, resolve institutional weaknesses or guarantee that the next drought will be less disruptive. The real test for the Government is whether it can turn the present crisis into a sustained programme of reform\u2014one that survives changes of administration and delivers measurable improvements.<\/span><\/p>\n
