Krishna pipeline linkage saves 18 MGD water during maintenance
The Hyderabad Metropolitan Water Supply & Sewerage Board (HMWS&SB) said it saved 18 million gallons per day (MGD) of treated drinking water during maintenance of the Krishna supply network by linking phase-I, phase-II and phase-III pipelines at the Nasarlapally pumping station. During a shutdown of the phase-II main pipeline, around 18 MGD out of 23 MGD available was diverted to the phase-III reservoir for public use, while 5 MGD was released through scouring.
Officials said the new arrangement cut scouring time from nearly 20 hours to eight hours, saving over 12 hours of shutdown and about Rs 5 lakh in electricity costs. The board also replaced 48 air valves on the main pipeline during the shutdown. It is now considering similar linkage systems at Godakondla, Kodandapur and other pumping stations to reduce water losses during future maintenance.
Indian Opinion Analysis
The saved 18 MGD represents 80% of the water that would have been wasted, directly benefiting Hyderabad's public supply during maintenance. The 12-hour reduction in shutdown time and Rs 5 lakh in electricity savings show the operational efficiency gained. The board's plan to replicate the linkage at Godakondla and Kodandapur suggests this is not a one-off fix but a template for future network upgrades. The unresolved question is the condition of the ageing 24-km Nasarlapally-Godakondla stretch, where several scouring arrangements are either old or inaccessible.
