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 challenged communities across the North. Today, however, a monumental shift is underway along the windswept Vadamaradchi coast.

To understand how Sri Lanka is rewriting its water security playbook, one need only look to the Thalaiyadi Seawater Reverse Osmosis (SWRO) Plant.

V. Vijayakanth, Chief Engineer of the Jaffna Kilinochchi Water Supply and Sanitation Project (JKWSSP), recently explained the engineering marvels, environmental safeguards, and long-term vision driving this landmark infrastructure project.

“Building a multi-million-gallon desalination plant on an open, deep-sea coastline facing the Indian Ocean was no small feat,” he said.

Vijayakanth noted that the project required extensive marine, geotechnical, and ecological investigations before a single pipe was laid.

“The scale of the marine installation was striking: an intake and outfall system featuring roughly 1,300 metres of large-diameter pipeline, buried two metres beneath the seabed in water depths reaching up to 12 metres. Because ocean work is strictly dictated by nature, the team had to mobilise an excavator-mounted barge from India and execute a complex offshore operation within a very tight window before the onset of the monsoon.”

“One of the greatest historical hurdles of reverse osmosis technology has been its heavy appetite for electricity. To keep operational costs in check, the Thalaiyady plant integrates state-of-the-art isobaric pressure-exchanger energy recovery systems. These devices capture hydraulic energy from the high-pressure brine reject stream and transfer it directly back to the incoming seawater feed – recovering roughly 95% of available energy and slashing power requirements.”

“Environmental stewardship was equally central to the design. To prevent high-salinity discharge from harming the marine ecosystem, the plant utilizes an offshore outfall equipped with specialized diffusers positioned more than 500 metres from the shore. This ensures rapid mixing within a tightly monitored zone, safeguarding local marine life,” he said.

Karaveddi Water Supply Scheme

The impact of the plant is already tangible on the ground. Producing water that meets rigorous national quality standards (SLS 614:2013), the facility feeds into a vast transmission network linked to elevated service reservoirs. These tanks regulate hydraulic pressure across sprawling distribution routes, bringing relief to areas historically plagued by hard, brackish water.

Currently, about 1,600 households in the Karaveddi Zone are actively connected to the desalinated supply, with water flowing across a regional network stretching from Kodikamam and Jaffna City down to distant island communities like Delft, Kayts and Punguduthivu.

The peninsula’s total daily drinking water demand hovers around 50,000 cubic metres for a population of roughly 600,000. Operating at full capacity, the Thalaiyadi plant yields 24,000 cubic metres per day – meeting nearly half of the region’s current needs.

Yet, planners are already looking decades ahead. Driven by economic development, tourism, and proposed industrial zones like Kankesanthurai, projected potable water requirements for domestic, commercial, and industrial needs are expected to climb from 95,000 cubic metres per day in 2025 to 135,000 by 2045, and 175,000 by 2065. Meeting this future trajectory will require a diversified national strategy combining desalination with surface-water preservation and rainwater harvesting.

When asked whether Sri Lanka should lean exclusively on seawater conversion amid intensifying climate volatility, Vijayakanth emphasised the need for a balanced approach: “Sri Lanka should adopt a diversified water-security strategy, prioritising sustainable surface-water development, groundwater protection, rainwater harvesting, water conservation, treated wastewater reuse and catchment protection. Desalination can complement these sources as a valuable climate-resilient and drought-proof option where appropriate.”

Backed by financial and technical collaboration from the Asian Development Bank (ADB), the project has given the National Water Supply and Drainage Board (NWSDB) invaluable expertise in advanced desalination management. Crucially, a two-year hands-on training program is ensuring that local technical staff master everything from membrane upkeep to preventive maintenance.

As climate variability accelerates, Thalaiyadi serves as a vital proof-of-concept. While energy-intensive desalination cannot replace conventional freshwater sources everywhere, Vijayakanth emphasises that it stands as an indispensable, drought-proof shield for Sri Lanka’s vulnerable dry zones – turning the ocean itself into a secure foundation for the nation’s future.

NSB Group delivers Rs.22.5bn operating profit in 1H 2026 as lending and core income strengthen

Published

Dr. Harsha Cabral / Rohana Bandara Weerakoon

National Savings Bank Group (NSB) recorded resilient core banking performance during the first six months of 2026, supported by stronger net interest income, a notable expansion in fee-based earnings and continued growth in loans and advances. The results demonstrate the Bank’s capacity to maintain business momentum while navigating cost pressures and volatility in market-related income.

The Bank reported total operating income of Rs. 45.8 billion for the period, an increase of 3.1% compared with Rs. 44.5 billion in the corresponding period of 2025. Net operating income increased by 2.3% to Rs. 49.1 billion from Rs. 48 billion reported a year ago, providing a stable foundation for the Bank’s operations and customer-focused growth agenda.

Net interest income rose by 5.5% year-on-year to Rs. 44.2 billion, compared with Rs. 41.9 billion in the first half of 2025. This improvement was supported by a 4.7% reduction in interest expenses to Rs. 54.5 billion, despite a marginal moderation in interest income to Rs. 98.6 billion. The result reflects disciplined balance-sheet management and the Bank’s continued focus on maintaining a sustainable funding and asset mix.

The Bank also achieved substantial growth in fee-based earnings. Net fee and commission income increased by 37.0% to Rs. 1.40 billion, from Rs. 1.02 billion a year earlier. The increase underlines the growing contribution from transaction-led services and the Bank’s ongoing efforts to broaden non-interest revenue through customer-centric and digitally enabled banking solutions.

Profit before Tax (PBT) amounted to Rs. 22.6 billion, compared with Rs. 24.1 billion in the first half of 2025, while profit after tax stood at Rs. 13.4 billion, compared with Rs. 14.7 billion. The moderation in profitability principally reflected higher operating costs and the lower contribution from trading and derecognition gains. Personnel expenses increased to Rs. 13.8 billion from Rs. 11.5 billion, while other operating expenses rose to Rs. 4.3 billion from Rs. 4.1 billion.

Despite these pressures, the Bank preserved a substantial earnings base and continued to invest in the people, systems and service capabilities required to improve operational resilience and the customer experience. Income tax for the period amounted to Rs. 9.14 billion, while VAT and the Social Security Contribution Levy on financial services together exceeded Rs. 7.29 billion. In addition, the Bank declared a dividend of Rs. 7.4 billion to the Government as its sole shareholder. Accordingly, NSB’s total contribution to the Government through dividends, taxes and levies amounted to Rs. 23.8 billion, underscoring the Bank’s significant contribution to public finances and national development.

Commenting on the results, National Savings Bank Chairman Dr. Harsha Cabral PC said: “The first-half results reflect the resilience of NSB’s core business model and the enduring confidence placed in the Bank by generations of Sri Lankans. Our priority remains the prudent stewardship of public savings while supporting productive economic activity, financial inclusion and sustainable national development.”

NSB’s total assets increased by 2.1% during the first six months of the year to Rs. 1.87 trillion, from Rs. 1.83 trillion at end-December 2025. Loans and advances recorded a strong 9.1% expansion to Rs. 601.01 billion from Rs. 550.83 billion, demonstrating the Bank’s continued support for the financing needs of individuals, households and eligible institutional customers within its mandate.

Deposits, the principal source of funding for NSB, increased by 1.5% to Rs. 1.63 trillion from Rs. 1.61 trillion. The sustained growth in the deposit base reflects continued public confidence in the Bank and provides a stable platform for its savings-led business model. The Bank’s financial position remained sound, with total shareholders’ equity increasing by 4.1% to Rs. 123.91 billion from Rs. 119.05 billion. Retained earnings rose by 12.4% to Rs. 52.34 billion, further strengthening the Bank’s capacity to support future growth and absorb potential shocks.

Acting General Manager/CEO of National Savings Bank, Mr. Rohana Bandara Weerakoon, said: “Our focus is on translating the Bank’s trusted savings franchise into sustainable customer value. The growth achieved in lending, fee income and shareholder’s equity is encouraging. We will continue to strengthen digital access, service quality, cost discipline and risk management while delivering on NSB’s national mandate.”

The Bank’s profitability indicators continued to reflect the strength of its core banking activities, although higher operating expenses moderated overall returns. The net interest margin improved to 4.81% from 4.74% at the end of 2025, demonstrating an improvement in the Bank’s core interest spread. Return on assets before tax remained broadly stable at 2.46%, compared with 2.48%, while return on equity stood at 22.30%, compared with 25.08% at the end of 2025.

Asset quality improved during the first half of 2026. The net Stage 3 loans ratio declined to 2.05% from 2.52% at the end of 2025, indicating a reduction in net impaired credit exposures relative to the loan portfolio. At the same time, the Stage 3 impairment coverage ratio strengthened to 59.77% from 58.54%, reflecting improved impairment coverage against Stage 3 loans.

NSB maintained capital buffers comfortably above the applicable regulatory minimum requirements. The Tier 1 capital ratio stood at 19.72%, compared with the regulatory minimum of 8.5%, while the total capital ratio stood at 21.1%, well above the minimum requirement of 12.5%. These ratios demonstrate the Bank’s capacity to absorb potential risks while supporting continued business growth.

The Bank also maintained a strong liquidity and stable funding position. The all-currency liquidity coverage ratio stood at 311.88%, substantially above the statutory minimum of 100%, reflecting the availability of sufficient high-quality liquid assets to meet short-term liquidity requirements. The net stable funding ratio stood at 196.17%, also comfortably above the regulatory minimum of 100%, demonstrating the stability of the Bank’s longer-term funding profile.
