Water Board Diverts 18 MGD During Krishna Pipeline Shutdown
During maintenance, water usually has to be removed from the Krishna Phase-II pipeline.
The water board found a way to send most of that water to a reservoir instead of letting it go to waste.
About 18 million gallons a day went to the Phase-III reservoir.
Only about 5 million gallons a day had to be released through scouring.
This helped workers empty the pipeline in eight hours instead of about 20.
The shorter process saved more than 12 hours and about ₹5 lakh in power costs.
Workers also replaced 48 air valves during the shutdown.
The board is looking at whether it can use similar connections at other pumping stations.
HMWS&SB diverted about 18 million gallons a day from the Krishna Phase-II pipeline to a Phase-III reservoir during a recent shutdown.
The diversion reused nearly 80% of the water held in the pipeline; about 5 MGD was released through scouring.
The arrangement reduced the time needed to empty the pipeline from around 20 hours to eight hours.
Officials said the shorter shutdown saved more than 12 hours and about ₹5 lakh in power expenditure.
The board is considering similar interconnections at Godakondla, Kodandapur and other suitable pumping stations.
