Ambatale flood protection embankment undergoing repairs after seepage concerns

June 12, 2026 at 7:24 PM

Repair work is underway at the Ambatale flood protection embankment following seepage observed during recent flooding along the Kelani River.

The embankment serves as a key flood mitigation structure designed to prevent river water from overtopping into surrounding areas during periods of high water levels and to reduce flood risks for nearby communities.

During the recent flood situation, rising water levels in the Kelani River led to seepage being detected at one section of the embankment. While officials determined there was no immediate risk of a structural breach, the high water pressure had caused water to pass through soil layers within the embankment.

The incident raised concerns among residents in the area. The Disaster Management Centre advised people to move to safer locations, although some residents initially remained in their homes.

Minister of Transport, Highways and Urban Development Bimal Rathnayake and Deputy Minister Eranga Gunasekara later visited the site, met affected residents and assured them that a permanent technical solution would be implemented. Following those assurances, residents were relocated to safer locations.

Subsequently, the Sri Lanka Land Development Corporation (SLLDC) conducted preliminary engineering assessments and geological studies before referring the matter to the National Building Research Organisation (NBRO) for technical recommendations.

Following field inspections and technical evaluations, the NBRO recommended a series of remedial measures, including the installation of Reno mattresses, geotextile materials and improved drainage systems to protect the lower slope of the embankment and strengthen its stability.

The recommended rehabilitation work is now being carried out with the aim of preventing future seepage, improving the structural integrity of the embankment and enhancing protection for nearby communities during periods of high river levels.

The project is expected to strengthen flood resilience in the area and reduce risks to lives and property along the Kelani River basin. (Newswire)
