After the public protest against laying of boulders to prevent rapid soil erosion along the four-kilometre-long seacoast in central Mumbai spanning from Prabhadevi to Mahim, the civic body is set to put into action another technology to save the stretch.
To be inaugurated by senior Shiv Sena leader Manohar Joshi on Wednesday, the project entails placing geo-tubes on the beach. They are said to be an eco-friendly solution to prevent erosion along the beachfront.
The move was announced in August after the Brihanmumbai Municipal Corporation (BMC) faced severe flak from the residents of Shivaji Park for using boulders for the beach nourishment plan.
To begin with, the BMC will start soil testing at 30 places along the coast to gauge the porosity and the quality of soil below the sand. This task will be completed within three months.
Tenders will be floated after the study to place geo-tubes along the coast. The tubes, which are eco-friendly and do not create pollution, will be submerged along the beach with the help of sand-filled gunny bags.
Over time, a bay will form and marine life will grow on the tubes, creating a reef-like structure. This will also attract fish.
This technology, which was used at INS Hamla in Malad, uses thick synthetic permeable geo-textile with uniquely designed retention properties to reduce soil erosion.
“We have assessed various technologies and have concluded that this is by far the best in the world which has worked on similar coasts,” said civic standing committee chairman Rahul Shewale.
The civic body has estimated the project cost at Rs12.6 crore, which has been given a go-ahead in the 13th finance plan, and has also got a nod from the maritime board.
