GUWAHATI, July 13: Till the midst of summer, the city residents seem less troubled with rain water and its consequent artificial flood across Guwahati, at least in compare to the previous years. However, the phenomenon may turn quite souring in the days to come, as there are two more months to wrap the season.
There were at least three-four rounds of heavy shower that the city has experienced so far. However, except Jorabat, it did not lead to the kind that would have otherwise inundated the flood-prone areas of the city like Anil Nagar, Nabin Nagar, Rajgarh and Zoo Raod Tinali. Hence, the city is yet to register a flash flood of high magnitude.
For the little improvement manifested this year, the commissioning of the Noonmati drainage system and the desiltation drives undertaken by Guwahati Metropolitan Development Authority (GMDA), Guwahati Municipal Corporation (GMC) and Public Works Department (PWD) must be given due credit.
Earlier, the Nabin Nagar and Anil Nagar areas remained as natural basin during summer, as rain water from upland Jyotinagar and Sunsali Hills flowed in via Noonmati, Bamunimaidan and Zoo Road flooding these areas too. Eventually, the Bharalu River turned turbulent and the artificial flood wave reversed its course. Notably, the construction of Noonmati drain has diverted the usual flow of rainwater which has already been directly channeled into the Brahmaputra through Bonda Jan area.
The Noonmati drainage system that was proposed in 2013 is about 5 km long and was built in two phases. The width of the drain is 6 metres and the depth varies from 3 metres to 5.50 metres (including foundation depth).
The de-siltation works were jointly conducted by GMDA, GMC and PWD in different locations in and around Guwahati while the GMDA has dredged the major water canals like Seelsako, Pamohi and Barkhola.
However, the phenomenon has been shifted to Jorabat along the NH-37 for which departments concerned must step up measures to mitigate the problem.
