Is Tap Water Safe to Drink in Seychelles?

The Public Utilities Corporation (PUC) sources water primarily from surface reservoirs including La Gogue Dam and Rochon Dam on Mahé, supplemented by increasing reliance on reverse-osmosis desalination plants to cope with seasonal shortages. Praslin and La Digue depend more heavily on desalination and smaller catchment reservoirs due to limited freshwater streams.

Water quality is generally well managed, though heavy rainfall events can cause temporary turbidity spikes in reservoir-fed supply, and older pipe sections on Mahé occasionally cause discoloration. Desalinated water on smaller islands is closely monitored and rarely poses contamination risk.

Mahé, home to the capital Victoria, has the most robust treatment infrastructure, while Praslin and La Digue's smaller systems can experience temporary shortages during dry periods (typically June to September) that lead to water rationing rather than quality issues.

Reservoir-sourced water on Mahé is relatively soft, around 30–70 mg/L, while desalinated water on Praslin and La Digue is typically very soft, often below 30 mg/L..

Most Seychellois drink tap water directly without treatment, and bottled water is purchased mainly for convenience or personal taste preference rather than safety concerns.

• •Tap water is safe to drink on all three main islands under normal conditions
• •During dry-season rationing, follow local guidance if desalination output is reduced
• •Bottled water is still widely available for personal preference
• •Reusable bottles are encouraged given the reliable tap supply

• •Follow PUC advisories during rare dry-season low-pressure periods
• •No special precautions are typically needed for visitors
