The Hon. Arkam Ilyas
Hon. Arkam Ilyas seconded the Adjournment Motion on recurrent flooding in the Nilwala River basin, noting severe impacts on several Matara District divisional areas, paddy lands, public property, and towns. He questioned the effectiveness of the downstream salinity barrier and past incomplete river development projects, and proposed an expert committee including state agencies, engineers, and affected communities to identify solutions. He also suggested short-term relief measures such as partial removal of sheet piles near the salinity barrier and widening a temporary canal, while calling for speedy and sustainable flood, drinking water, and irrigation solutions.
Verbatim record (translated)
Machine-translated from Sinhala / Tamil / English¶ 01 Hon. Speaker, I second the Adjournment Motion moved by Hon. (Prof.) L.M. Abeywickrama.
¶ 02 People in Matara District have suffered for decades due to flood conditions associated with the Nilwala River. In particular, the Divisional Secretary’s Divisions of Matara, Akuressa, Athuraliya, Malimbada, Thihagoda and Kamburupitiya face recurrent floods several times a year. Around 20,000 acres of paddy fields, large amounts of public property, and several towns are repeatedly affected.
¶ 03 Many residents and farmers allege that the salinity barrier constructed downstream is a major cause. Nearly Rs. 3 billion was spent, but we question whether it delivers intended outcomes. Therefore, with an expert committee’s assistance, we should find solutions and determine how to manage the situation.
¶ 04 Past projects on Nilwala have failed. A French company’s multi-phase development plan only implemented one phase, worsening matters. The plan envisaged multiple reservoirs in the upper Nilwala, but for 35–40 years we have not implemented it. If implemented, it could address floods, provide drinking water, ensure irrigation during dry seasons, and supply water to water-scarce areas like Hambantota District.
¶ 05 We propose a committee comprising the Presidential Secretary’s committee, the Water Board, the Department of Irrigation, IESL, and representatives of affected farmers and residents to arrive at prompt, appropriate decisions. Several senior Sri Lankan engineers with international experience are willing to contribute, including Dr. Wasantha Lal, with around 30 years’ experience with the U.S. Army Corps of Engineers on rivers and water resources.
¶ 06 As a short-term measure, since urgent relief is needed, we believe partial removal of sheet piles on both sides of the salinity barrier and widening the temporary canal across the river could help. We request speedy, sustainable solutions.
¶ 07 Thank you.
