  "account": "The Jaffna Peninsula of Sri Lanka has long faced water scarcity issues due to its reliance on an underground freshwater lens and a lack of major perennial rivers. Recently, a significant shift in water management has taken place with the construction of the Thalaiyadi Seawater Reverse Osmosis (SWRO) Plant. V. Vijayakanth, Chief Engineer of the Jaffna Kilinochchi Water Supply and Sanitation Project, explained the challenges and innovations behind this project. Building a large-scale desalination plant on an open coastline required extensive investigations and complex marine operations, including laying over 1,300 meters of large-diameter pipeline buried two meters beneath the seabed in up to 12 meters of water depth. To address the high electricity demand of reverse osmosis technology, the plant employs energy recovery systems that capture and reuse hydraulic energy from high-pressure brine, reducing power requirements by around 95%. Environmental concerns were addressed through an offshore outfall equipped with specialized diffusers positioned more than 500 meters from the shore, ensuring rapid mixing and protecting local marine life. The Thalaiyadi plant, producing water that meets national quality standards, provides drinking water to about 1,600 households in the Karaveddi Zone, which stretches from Kodikamam and Jaffna City down to island communities like Delft, Kayts, and Punguduthivu. Currently, the plant meets nearly half of the region's daily drinking water demand, with a capacity of 24,000 cubic meters per day. Looking ahead, as the projected potable water requirements are expected to rise from 95,000 cubic meters per day in 2025 to 175,000 by 2065, the Thalaiyadi plant serves as a blueprint for a diversified water-security strategy in Sri Lanka, combining desalination with surface-water preservation and rainwater harvesting.",
  "summary": "Sri Lanka should adopt a diversified water-security strategy, says chief engineer By Sanath Nanayakkare For generations, the Jaffna Peninsula has relied almost entirely on an underground freshwater lens. With no major perennial rivers to lean on, the region has long walked a tightrope between water scarcity, seasonal droughts, and a creeping groundwater salinity that has […]",
