Not rated — no significant reservoirs
Saint Kitts and Nevis is set aside from the ranking rather than graded. Having no significant reservoir storage is a geographic fact, not a transparency failure — so assigning an “F” would be misleading.
H1 2026 Evaluation
Saint Kitts and Nevis Reservoir Transparency
N/AWhy it's not rated
No storage reservoirs above the qualifying scale: surface intakes feed only small distribution tanks (20,000-1,000,000 gal).
Where its water comes from
~30% river surface intake and ~70% groundwater wells; a Basseterre desalination plant was commissioned in 2026.

Saint Kitts and Nevis has a functioning water supply infrastructure with genuine surface water intake from multiple rivers and distribution storage across the island, making it slightly more infrastructure-rich than the pure structural zeros in this evaluation group. The February 2026 commissioning of the Basseterre desalination plant — described by the government as 'historic' and providing water security to nearly 70% of the population — represents a significant shift in the country's water supply mix, reducing dependence on surface water and groundwater. Despite this infrastructure, the RTI score is near-zero because the Water Services Department (water.gov.kn) functions as a communications office rather than an operational data publisher. The department's website provides contact details, billing information, FAQs, and ad-hoc press statements, but no numerical data on river abstraction volumes, storage tank levels, or water production statistics. The Nevis Water Department operates independently for the island of Nevis and similarly publishes no operational data. With the new desalination plant shifting water supply toward a more industrial, metered-production model, there is a structural opportunity for the government to publish desalination output data — but as of the evaluation date, no such publication has been identified. The ongoing Rural Water Supply Network profiling (rural-water-supply.net) documents the country's water system at a planning level but is externally maintained.
