Residents and businesses across the Galle Municipal Council area should prepare for a significant disruption to their water supply tomorrow, 10 June 2026, as the National Water Supply and Drainage Board (NWSDB) has announced a 14-hour water cut to facilitate essential maintenance work. The prolonged interruption will affect thousands of households and commercial establishments in Sri Lanka's southern coastal city.

The water cut in Galle tomorrow is scheduled to begin early in the morning and continue through the evening hours, requiring residents to make advance preparations for their daily water needs. The NWSDB has emphasised that the extended disruption is necessary to carry out critical infrastructure maintenance that cannot be postponed.

Areas Affected by the Water Supply Disruption

The water supply interruption will impact the entire Galle Municipal Council jurisdiction, one of the Southern Province's most densely populated urban centres. Galle serves as a vital commercial and tourism hub, with the historic Galle Fort area attracting visitors year-round. The timing of the maintenance work may cause inconvenience to the hospitality sector, which has been experiencing growth as Sri Lanka Tourism Crosses 900,000 Arrivals in 2026, Rs. 4 Billion Global Campaign Planned.

Local authorities have urged hotels, guesthouses, restaurants, and hospitals in the affected areas to store adequate water supplies in advance. Domestic consumers have been advised to fill storage tanks and containers before the scheduled commencement of the maintenance work.

Essential Maintenance Work Details

While the NWSDB has not disclosed specific technical details about the maintenance activities, such extended water cuts typically involve major pipeline repairs, valve replacements, or reservoir cleaning operations. The 14-hour duration suggests substantial work that requires complete drainage of distribution systems to ensure worker safety and repair quality.

Water infrastructure maintenance is crucial for preventing larger-scale failures that could result in even longer disruptions. The National Water Supply and Drainage Board regularly schedules such interventions to maintain service reliability across Sri Lanka's water distribution networks.

Preparation Guidelines for Residents

The NWSDB has issued several recommendations for consumers to minimise inconvenience during tomorrow's water supply disruption. Households should store sufficient water for drinking, cooking, and essential hygiene needs well before the cut begins. Residents are advised to fill bathtubs, large containers, and all available storage vessels.

Commercial establishments, particularly those in the food service and healthcare sectors, should verify their backup water storage capacity and consider postponing non-essential water-intensive operations until normal supply resumes. Schools and educational institutions within the municipal limits may need to adjust their schedules if the disruption extends beyond anticipated timelines.

Water Supply Restoration Timeline

According to the announcement from the National Water Supply and Drainage Board, normal water supply is expected to resume after the completion of the 14-hour maintenance window. However, consumers should note that full pressure restoration across the distribution network may take additional time as the system is gradually refilled and air pockets are cleared from pipelines.

Some areas, particularly those at higher elevations or at the periphery of the distribution network, may experience lower pressure or intermittent supply for several hours after the official restoration time. The NWSDB typically monitors pressure levels across the network and makes adjustments to ensure equitable distribution during the recovery period.

Contact Information for Emergencies

Residents experiencing extended disruptions beyond the announced period or facing emergency situations during the water cut should contact the NWSDB hotline for assistance. The water board maintains emergency response teams to address critical situations, particularly those affecting hospitals, care facilities, and other essential services.

The Galle Municipal Council area has experienced similar scheduled maintenance disruptions in the past, though 14-hour cuts remain relatively uncommon and indicate the scale of work being undertaken. Cooperation from consumers during such planned interventions helps ensure the long-term reliability of water supply infrastructure serving the historic southern city.
