The Kolkata Metropolitan Development Authority (KMDA), with the help of a Mumbai-based firm, is drawing up a plan to harvest storm water to recharge the groundwater table along the five-km stretch of EM bypass from Ultadanga to Chinrighat. Save it with the country’s government’s “Jal Dharo Jal Bharo” scheme to harvest rainwater, which can be used to artificially recharge the city’s depleting groundwater table.
According to KMDA officials, EM Bypass and its surrounding districts are the first to be considered for such rainfall harvesting and synthetic groundwater recharge schemes.
“Presently, there is no stormwater drainage point between the Jap drainage channel at Chingrighata and the Gol canal at Ultadanga. The accumulated stormwater of this five-kilometer-long bypass stretch is now flowing towards the canal through the drainage network system. The layout is to store stormwater and waste floor water that accumulates in this stretch and channel it underground to recharge the groundwater,” said an official.
The stored stormwater would be captured and drained via different channels, in accordance with officials. “The water will omit thru a filter medium earlier than it is channelized to the underground water at the level the place it may want to be recharged. It will just be a reverse system of the way groundwater is pulled up doing filtering. Not only may want the excess stormwater be right utilized and discharged to stop waterlogging but the groundwater would additionally get recharged. The corporation drawing up the diagram is additionally coming up with suggestions for the normal upgrade of the drainage community machine of Bypass,” stated a KMDA official.
