The Water and Sewerage Company Inc. (WASCO) of Saint Lucia has opened a formal investigation into unauthorized tampering with a retired valve on the main transmission line that feeds the Delcer Water Treatment Plant, an incident that worsened existing water supply challenges in the island’s southern region. The utility company announced in an official statement that its combined production, treatment and water quality inspection team first detected unusual operational irregularities at the valve site located in Unionville on August 12.
Upon preliminary inspection, teams confirmed that the decommissioned valve, positioned along the critical water corridor between the source intake and the Delcer processing facility, had been deliberately interfered with. This tampering act intentionally restricted the volume of water flowing into the plant, cutting its operational output at a time when the southern water network was already strained by severe drought conditions. Quick-responding WASCO technicians were dispatched immediately to the site to repair and secure the valve, successfully restoring the treatment plant to its full working capacity within a short timeframe.
As the investigation into the unauthorized interference moves forward, WASCO has already rolled out new proactive measures to beef up physical security for all its critical infrastructure across the Unionville area and surrounding southern districts. The company also issued a public reminder that willful tampering with or destruction of public water infrastructure is classified as a criminal offense under Section 90 of the island’s Water and Sewerage Act, carrying legal consequences for perpetrators.
Beyond the infrastructure tampering incident, WASCO confirmed that Delcer and several other southern water distribution networks are already grappling with persistent low water flows, driven by months of below-average rainfall that has cut water output at all of the island’s water abstraction points. Data from the Saint Lucia Meteorological Services shows that by the end of July, the southern rainfall monitoring station had recorded a total cumulative deficit of nearly 45% compared to historical averages. Current long-term forecasts call for continued drier-than-normal conditions across the region through the end of November, meaning water supply constraints are likely to persist for months.
To manage the ongoing drought situation, WASCO says it will maintain daily round-the-clock monitoring of water intake conditions at all key facilities, and will conduct targeted desilting work whenever conditions require it to maintain maximum output. The utility is also calling on all residential customers across the affected southern regions to cut back on non-essential water use, reserving available supplies only for critical household needs until natural water flows recover. It has encouraged consumers to tap into harvested rainwater supplies for all non-drinking uses such as gardening, cleaning and outdoor washing to reduce pressure on the public network.
In closing, WASCO reminded the public that all updated, accurate information about water supply status and infrastructure developments will be released exclusively through its official communication channels, urging residents to avoid spreading or relying on unconfirmed information from unofficial sources.
