Veli Artificial Breakwater project to prevent Trivandrum’s water-logging problem

Currently the authorities in-charge of Operation Anantha are focusing on removing blocks in drains before May 20.

In view of the high tide during monsoon season, the Trivandrum district administration is planning to revive the breakwater facility at Veli Lake, a project that was proposed a long time ago.  Now the project is reconsidered under the long-term plan of Operation Anantha which aims to prevent waterlogging in the city.

The Veli Artificial Breakwater project is expected to reduce the waterlogging problem at Thampanoor.

Water from Ulloor, Pattom and Amayizhanchan canals converge at Kannammoola and is discharged into Veli backwaters through Akkulam. Sandbars are formed naturally between the backwaters and the sea and during high tide, water is forced back and it surges in the reverse direction. This in turn causes waterlogging at Thampanoor and East Fort.

The project prepared by harbour engineering department consist of construction of an artificial breakwater chain that would prevent deposit of sand and formation of sand bars. The project is expected to reduce the waterlogging problem at Thampanoor.

According to the officials the results of Operation Anantha might not be visible this monsoon.

According to the officials who are in-charge of Operation Anantha, the results of eviction drive and clearing of canals at Thampanoor and East Fort might not be visible this monsoon. This is because a parallel canal beneath the railway lines should be built to divert the rain water to Pazhavangadi. Since it involves Railway lines, push-through technology should be used which will take at least 3 months to complete.

Only available solution is to clean the existing canal. However there is still a chance of rails getting flooded since most of the nearby drains have been cleared and water flow would be stronger. Currently the authorities are focusing on removing blocks in drains before May 20.
