Navi Mumbai civic body installs gabion wall in 17 out of 23 lakes to prevent them from getting polluted during visarjan

Keeping in mind the poor response it received from residents, who refused to use artificial ponds for visarjan, the Navi Mumbai Municipal Corporation (NMMC) this year installed gabion walls inside the lakes to prevent them from getting polluted.

Deputy Municipal Comm-issioner Jagannath Sinnarkar said, “We had constructed artificial ponds to save the natural ones from the chemicals that are released by the PoP idols after visarjan, but got a poor response from the people.

Because we have to protect the lakes from getting polluted, we decided to use the Italian concept of installing a gabion wall. We experimented with the process three years ago. After getting a good response in our jurisdiction, as many 17 out of 23 lakes at important locations now have a gabion wall in them.”

Resident speak
Vashi resident Kiran Bhave said, “The concept of constructing a wall in the lake is beneficial, as we get to immerse the idols in natural water without polluting the entire water body.”

How it works
NMMC officials said the process involves splitting the lake in two parts by constructing a wall in the middle. A gabion wall is a retaining wall made of stones filled in gabion rings, tied together using metal wires.

Once the wall is constructed, only one half of the lake can be utilised for immersion and is cleaned after a few months. A gabion wall prevents harmful chemicals, used in making idols, from polluting the entire water body.
