GUWAHATI, May 5: A great relief to the city dwellers, particularly to those who are residing in the artificial flood-prone areas of Guwahati, as the Guwahati Metropolitan Development Authority (GMDA) has been materializing a proposal to divert storm water. In an official communiqué shared to the media on Saturday, the authority said that the occasional water logging problem in the Zoo Road area due to torrential rains during monsoon season has been a great matter of concern for Guwahati Development Department, and thus for GMDA as well.
GMDA to divert storm water
The authority expressed that due to the geographical condition, the rain water of Jyotinagar Hill Catchment Area starting from Bamunimaidum to Sunsali Hill, including Guwahati Refinery Complex, flows towards Bharalu via Zoo Road and creates havoc in areas like Anil Nagar, Nabin Nagar etc.
“To mitigate the problem of water logging in these places, GMDA has proposed to divert the storm water of these catchment areas towards Bonda Jan and then to Brahmaputra River. GMDA has constructed a drain from Bamunimaidum to Noonmati to prevent existing flow of water towards Zoo Road. Pumps have also been installed to divert water through this Noonmati Drainage system”, said the communiqué.
According to the communiqué, the project cost is Rs. 26.00 crore for Phase – I. The total length of the drain already constructed is 1700 metres. The width of the drain is 6 metres and the depth varies from 3 metres to 5.50 metres (including foundation depth). The drain has been constructed with RCC framed structure as per requirement of railway department as it is constructed on railway land. The pump’s capacity is 4000 litres per second which is likely to be increased in due course.
It is expected that at least 25% of the water level of R.G. Baruah Road will be reduced due to diversion of this storm water using this proposed prevention method, the communiqué added.
