Sensors track every drop and its supply path, also plugging leakages

With the installation of 39 water flow monitoring sensors at key offtake points from Tungabhadra Dam to each diversion canal on the High Level Canal (HLC) and Low Level Canal (LLC) for live monitoring under the Tungabhadra Board Canal Monitoring System, Anantapur district received its due quota last season, which was 6 tmcft more than the previous year.

Eyes on the water

Tungabhadra Dam Superintending Engineer (SE) K. Venkata Ramana while explaining the working of the system at Hospet said the system was installed at a cost of Rs.7 crore. Sensors at another eight locations was proposed this year, which would give the minutest detail of where the water has gone and who has utilised it. Last year due to the presence of the monitoring mechanism on the HLC about 6 tmcft additional water could be sent to Anantapur district compared to the previous year as all leakages could be effectively plugged, he said. “The board had identified 1 tmcft of additional drawing by the canal system in Karnataka, so they were booked for that quantity and this year too monitoring was on, which can be seen online by anyone at http://tbbliveflow.com/ ,” he explained. The amount water flow at a particular point, and total quantum of water flowing in 24 hours also gets recorded.

Assured for one crop

Due to the siltation of the Tungabhadra Dam, the capacity has reduced by 30 tmcft. Out of the 133 tmcft capacity, only about 105 tmcft was available now and for the entire season. The SE expects this year the yield to be 163 tmcft, while last year it was only 151 tmcft. Moreover, by July 25 last year 90 tmcft was available in the dam and water was released lifting the gates on July 20. The SE is confident of irrigating at least one crop this season, Kharif/Rabi, to the entire ayacut. This year, however, as on July 29, the total available water is 24.44 tmcft with an inflow of 14,683 cusecs against last year’s 54,380 on this day. The inflows on July 25 this year were 19,644 cusecs against 93,320 cusecs last year on that date. With inflows steadily increasing for four days last week, and remaining constant for some days, the engineers are hopeful of the dam filling up between mid-August and August-end.

Supply to Kurnool city

Inter-state project Tungabhadra Board Chairman D. Ranga Reddy took stock of the situation on Friday and Saturday and a decision will be taken on releasing water when the storage reaches 40 tmcft .

For Kurnool city, the board has decided to release water from the month-end following a request from District Collector G. Veerapandian.
