Krishna pipeline linkage saves 18 MGD water during maintenance
The Hyderabad Metropolitan Water Supply & Sewerage Board successfully saved 18 million gallons of water during pipeline maintenance by using a new interconnection system. This technical upgrade reduced water wastage and cut maintenance time significantly, leading to operational cost savings.
Why it matters
Efficient water management infrastructure is vital for urban sustainability and resource conservation in rapidly growing metropolitan areas.
The Hyderabad Metropolitan Water Supply & Sewerage Board (HMWS&SB) on Tuesday said it successfully reduced wastage of treated drinking water and saved 18 million gallons per day (MGD) during maintenance of the Krishna drinking water supply network. This was possible by establishing an interconnection between the phase-I, phase-II and phase-III main pipelines at the Nasarlapally pumping station.
The new linkage system was put to use during a recent shutdown of the phase-II main pipeline. Of the nearly 23 MGD water available in the pipeline, around 18 MGD or 80% was diverted to the phase-III reservoir for public consumption. About 5 MGD had to be released through scouring.
Officials said the arrangement reduced the time required for scouring from nearly 20 hours to just eight hours, saving more than 12 hours of shutdown time. The shorter shutdown also resulted in an estimated saving of around ₹5 lakh in electricity costs.
