Tolly’s Nullah Revival Study by INTACH and Industry Body
Tolly’s Nullah in Kolkata is a polluted channel that has been neglected for years.
A study by INTACH and the Bengal Chamber of Commerce and Industry suggests reviving it to make it a heritage waterfront with walkways, parks, and improved ghats.
The channel could also be used for water transport.
The Kolkata Municipal Corporation (KMC) is working on a World Bank-funded project to reduce pollution by treating sewage before it enters the nullah.
The study identified four ghats that could be restored to support the revival.
The project aims to reduce pollution in Tolly’s Nullah and the Hooghly River, which the Bidyadhari eventually merges with.
