HMWSSB has opened floodgates at Osmansagar, Himayatsagar and Manjeera Barrage following heavy inflows from monsoon rains. Officials said inflows were recorded earlier than usual, while Hussain Sagar also received high inflows. Water levels in all reservoirs are nearing full capacity

Hyderabad: The Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) has opened the floodgates of Osmansagar, Himayatsagar and Manjeera Barrage after about 45 mm of rainfall was recorded in nearly 20 per cent of the catchment areas.

Usually, September is the month when the Water Board releases water, but this year the heavy inflows began a month earlier.
