As a devastating prolonged drought continues to deepen across St. Vincent and the Grenadines (SVG), the state-owned Central Water and Sewerage Authority (CWSA) has rolled out expanded alternating day-and-night water rationing for most populated areas of the main island, while stepping up emergency water deliveries to the chronically water-scarce Grenadines islands.
The new restrictions, announced Sunday, cover large swathes of southern St. Vincent — which hosts the majority of the main island’s total population. Under the updated rules, these communities will face total water cuts from 10 a.m. to 4 p.m. daily, adding to existing overnight rationing that already shuts off supply from 10 p.m. to 5 a.m. The supply disruptions stem from critically low river flows feeding the island’s key Dalaway Water System, one of three major water sources strained by months of below-average rainfall.
The situation is far more dire in the Grenadines, an archipelago with no natural rivers or streams and no centralized municipal water network, where declining rainfall has left most residential cisterns completely dry. On Saturday, one day before the rationing announcement, CWSA deployed a local ferry to transport emergency water supplies to the Southern Grenadines, using truck-mounted tanks and pumps to refill private residential storage tanks and cisterns directly. Ahead of the Easter travel season, which draws thousands of visitors to the Grenadines annually, CWSA has already urged all travelers to bring their own sufficient personal water supplies to reduce strain on the islands’ limited existing reserves.
This escalating crisis is not unforeseen: as early as mid-January, CWSA warned the public that the 2025 rainy season had delivered only 50% of the average rainfall recorded over the prior four years. Official data shows just 687.1 millimeters of rain fell during the 2025 wet season, compared to an average of more than 1,450 millimeters in preceding years. With both surface reserves and underground aquifers left under-replenished, the Caribbean Climate Outlook Forum (CARICOF) forecast short-term drought lasting through March and long-term dry conditions extending through May 2026 — an outlook that has since been officially reconfirmed, placing SVG under a formal long-term drought watch.
CWSA first implemented targeted rationing in February, ramping up restrictions for communities served by the Montreal water system to twice-daily cuts by mid-month. By March 2, the Montreal and Mamoon water systems remained at the agency’s highest “Level Red” alert, meaning severe supply risk requiring mandatory strict conservation. At Level Red, all non-essential water use, including car washing and power washing, must be halted completely. Dalaway, previously at the lower “Level Yellow” advisory risk status, has now also moved into critical stress as drought conditions have worsened.
Affected areas now span from Vermont Valley to Calliaqua — including Largo Height, Green Hill, and Lodge Village — as well as the Marriaqua Valley and surrounding communities. CWSA is urging all residents in impacted zones to immediately activate personal home water storage systems, a step the agency first recommended back in January. The authority also advised customers to monitor its official Facebook page and local radio broadcasts for the latest updates to rationing schedules and drought conditions, noting that supply disruptions will remain in place until rainfall levels rebound enough to replenish stressed water sources. CWSA has reaffirmed its commitment to delivering safe, affordable water services and will continue updating the public as conditions evolve.
