BANGKOK, 20 May 2013 – The Bangkok Metropolitan Administration (BMA) is dredging canals and reducing the water levels in various “monkey-cheek” water retention areas in preparation for the rainy season this year.
Deputy Governor of Bangkok Amorn Kitchawengkul said on Monday that the Department of Drainage and Sewerage was sending its mobile units to install water pumps on main roads and dredge canals and sewers of a combined length of 6,090 kilometers. The dredging work is expected to finish in July this year. In the meantime, Mr Amorn added that the department was also decreasing the water volumes in monkey-cheek reservoirs to have enough storage space for the rainfall this year.
The BMA has forecast that this year’s rainfall will be no less than last year’s and, with a precipitation rate of 60 millimeters per hour, it will take no more than three hours to drain the water after the rain stops.
