Kendrapara, September 4 (LocalWire): The district authorities have sought help of experts from the IIT Chennai to repair 15 gabbon boxes of the geo-synthetic sea wall near village Pentha in Rajnagar block of Kendrapara district.
According to reports, portion of the geo-synthetic tube, that was used as a protective wall against sea erosion, was gutted in a mysterious fire on Saturday night.
“We have temporarily repaired the sea wall by placing sand bags.
We will be fixing it with the help of the experts from IIT Chennai,” Aul Saline Embankment Division executive engineer Purnachandra Rath said.
“We held deliberations with the district administration and police regarding the safety of the geo-tubes and they have assured us to guard the sea-wall,” the officer added.
The geo–synthetic tube based sea wall in Pentha was built by Pune-based Garaware Rope Limited in 2016.
“During Titili cyclone a year ago, a portion of the geo-tube was washed away and the company had repaired it in consultation with IIT Chennai,” Rath said.
The state government had built the 600-meter geo-synthetic sea wall in 2016 as part of its Integrated Coastal Zone Management (ICZM) programme at the cost of Rs 39 crore, with technical support from IIT Chennai.
The 505-metre-long wall consisting of 241 geo-tubes was installed to tackle sea erosion along the coast at Pentha in Brahmansahi gram panchayat in Kendrapara district.
“Earlier, the experts from IIT Chennai advised us to plant casuarinas in front of the geo-tubes to save the tubes from the tidal waves. However, due to lack of space on the beach, we shelved off the casuarinas plantation work and built the armory stone protection barrier,” Rath informed.
“This is the state’s first geo-synthetic tube wall project. The tube is made of a spun-bond polyester fabric sewn together to form a custom diameter tube.
The tube is interconnected along the sea water edge, and a small pump is used to fill the tube with the same sand and organic material that has been eroding into the sea,” the officer explained.
Locals alleged that while a large number of tourists visit Pentha every day, the authorities have not put in place adequate security measures for them and the sea wall.
They allege that miscreants from outside may have set fire to the geo-synthetic tube wall.
