All dams falling under earthquake-prone zones require a study to be conducted before getting the no objection certificate from the Central Water Commission.
One of the Brihanmumbai Municipal Corporation's (BMC) most ambitious projects to take care of the city's ever-growing water needs, Gargai dam has been in the pipeline for years. Taking the project one step closer to reality, the civic body has appointed the Central Water and Power Research Station (CWPRS) to conduct a study of the proposed Gargai dam's construction area that falls in seismic zone 3. It has also appointed WAPCOS LTD to conduct flood related studies under the guidance of Central Design Organisation, Nashik.
All dams falling under earthquake-prone zones require a study to be conducted before getting the no objection certificate from the Central Water Commission. The proposed site of Gargai dam falls under earthquake seismic zone 3 which is classified as Moderate Damage Risk Zone. Thus, the civic body has appointed the institute to study the site. "CWPRS is a government institute and is the only body which can conduct such studies," said a BMC official. The proposal of sanctioning the appointment of the institute has been passed in the standing committee meeting on Tuesday. Cost of the study is expected to be around Rs 13.77 lakh. The BMC made a provision of Rs 122 crore for the project in 2019-20 budget.
The dam is expected to add 440 million litres daily to the city's water supply.
The city gets a supply of 3,800 MLD of water daily from seven dams. Gargai, Pinjal and Damanganga dams will give additional water supply of 2891 MLD water to the city by 2050. The primary work of Gargai, which will be on Vaitarna river in Palghar, has already started and the civic body submitted various reports of the dam to different bodies for permission.
Of the other projects that are behind the schedule is the Pinjal Project which is with the state government and the disputed Damanganga Pinjal River Link Project which has to be signed by Gujarat and Maharashtra governments.
