With the Brihanmumbai Municipal Corporation (BMC) initiating the proposal to study the feasibility of laying an underground tunnel between Pinjal and Mumbai, the city can hope for an extra 865 million litres of water daily (MLD). The project, which was envisaged by the BMC following the Chitale committee report, is a part of the Gargai-Pinjal-Damanganga Project.
The civic body has decided to carry out a study at a cost of Rs2.29 crore. The study will include geological survey, contour-mapping, preparing maps and designs of a 65km-long underground tunnel and its various connections.
The study will also analyse the level of underground water table. It is expected that consultants would suggest ways to carry out work and coordinate with all departments concerned.
As per the project plan, a dam will be built across the Pinjal river in Jawahar taluka of Thane district, and two others across the Damanganga river, which flows across the borders of Gujarat and Maharashtra. Water from these dams will be supplied to Mumbai using a tunnel. Total amount of water to be drawn from the project will be approximately 1,586MLD.
The tunnel which will be laid from Pinjal to Gundavali (Andheri) will be joined to Bhandup Complex, where purification of water would be done.
