Mauritius’s Central Water Authority injects water into a network that loses 60 percent of it before reaching consumers. That single statistic, delivered by CWA Chief Engineer Satyajay Mohungoo at a recent workshop on sustainable tourism practices, captures the operational challenge now pressing on the island’s entire hospitality sector.
The CWA serves more than 400,000 consumers, yet only 40 percent of the water it distributes actually arrives at its intended destination. Inside tourism facilities, the inefficiency compounds. Daily water use per guest runs between 150 and 300 liters, with roughly 35 percent of that volume flowing through toilets and bathrooms alone. Fuel, electricity, and water costs together can consume up to 55 percent of a hospitality establishment’s total operating expenses, making resource management not a peripheral concern but a core financial one.
The good news, according to the CWA, is that targeted infrastructure upgrades can reduce water consumption by up to 40 percent. Low-flow showerheads, dual-flush toilets, faucet aerators and sensors, and smart irrigation systems are the most straightforward interventions. Performance dishwashers can cut water use by half. These are not experimental technologies; they are available now and deployable at scale.
More advanced systems offer additional gains. Rainwater harvesting can collect, filter, and store water for use in toilets, landscaping, laundry, pool filling, and vehicle washing. Greywater reuse, capturing water from showers, sinks, and laundry while excluding toilet water, can recover between 50 and 80 percent of that volume after appropriate treatment. Singapore already treats and bottles greywater, demonstrating what full-cycle water management looks like in practice.
Leak detection is equally critical to the delivery picture. A single dripping faucet wastes approximately 5,500 liters annually. A faulty toilet can lose as much as 200,000 liters per year. The CWA plans to deploy drones in the near future to improve leak identification across its network, a step that could meaningfully close the gap between water injected and water delivered.
Meanwhile, the broader operational context is tightening. Niven Muneesamy, director of the Tourism Authority, told workshop participants that the sector now operates under pressure from geopolitical crises, climate change, and intensifying regional competition. Tourism contributes up to 25 percent of Mauritius’s GDP and supports substantial employment, but the traditional operating model is no longer adequate to those conditions.
Anabelle Savabaddy, the delegated minister for tourism, put it plainly: “doing things as before is no longer possible.” She called on accommodation managers to treat every conservation measure, whether cutting energy use, reducing water consumption, minimizing waste, preventing food spoilage, or sourcing local products, as a direct contribution to operational efficiency and competitive positioning. Travelers, she noted, increasingly evaluate properties on environmental management, not only amenities or location.
To support implementation, the Horizon.eco platform has been introduced to allow operators to measure performance across waste, water, and energy metrics and communicate those results to guests.

The infrastructure upgrades, monitoring tools, and reuse systems described at the workshop are not aspirational. They are the operational levers available to an industry whose cost structure and resource base are both under strain. Whether Mauritius’s accommodation sector can deploy them at sufficient scale, and fast enough to close the gap between current practice and what the market now demands, is the question the sector’s operators will have to answer.
