Hyderabad’s water supply is expected to be restored gradually by 10 am on Tuesday after the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWS&SB) completes shutdown works on a major Krishna Drinking Water Supply Project pipeline.
The works are being carried out on the 2,375-mm-diameter mild steel pumping main between Nasarlapally and Godakondla under the Krishna Drinking Water Supply Project (KDWSP) Phase-II. HMWS&SB said the remaining work was expected to be completed by 9 pm on Monday, after which the pipeline would be charged in phases from 10 pm.
The shutdown includes the replacement of air valve tees at 45 locations and the rectification of leakage from a scour valve at Kurmed village. Air valves help release trapped air from pressurised pipelines, while scour valves are used to drain or flush sections of a water main. Faults at these points can affect the safe and reliable operation of large transmission systems.
“Water supply to the affected areas is expected to be restored gradually by 10 am on Tuesday,” the board said. The statement did not specify the individual neighbourhoods or the volume of supply affected by the shutdown.
The phased charging of the pipeline means supply restoration may not occur simultaneously across all affected locations. Water availability can return at different times depending on the sequence in which sections of the network are brought back into operation and the time required for the system to stabilise. HMWS&SB’s stated timeline refers to expected restoration rather than an immediate return to normal supply in every area.
The Krishna Drinking Water Supply Project is part of Hyderabad’s bulk water infrastructure, linking large-diameter transmission mains with the metropolitan distribution network. Maintenance on such mains requires planned shutdowns because repairs and valve replacement must be undertaken on depressurised sections of the system. The work also illustrates how faults at specific pipeline components can require coordinated intervention across a wider urban water network.
Alongside the shutdown update, HMWS&SB warned consumers about cyber fraud attempts involving people impersonating the water board. According to the board, callers or messages may seek payments or bill-related updates by claiming that a connection will be disconnected or that a water bill must be updated.
Consumers have been advised not to click links or download APK files received from unknown numbers. The board also cautioned against installing applications, enabling screen sharing or providing remote access to devices in response to such requests. It said consumers should not share one-time passwords, UPI PINs, debit or credit card details, CVVs, passwords or bank account information.
HMWS&SB advised residents to check and pay water bills only through its official channels. Anyone who notices a suspicious transaction should immediately contact their bank, secure the relevant account or card and report the incident to cybercrime authorities. The board also asked consumers to preserve SMS messages, phone numbers, links and transaction details as evidence.
The immediate operational milestone remains the completion of the repairs by 9 pm on Monday, followed by phased pipeline charging from 10 pm and the expected gradual restoration of water supply by 10 am on Tuesday.
