With water levels falling by the day, the Water Board is making arrangements to install pumpsets at Osmansagar and Himayatsagar reservoirs by month-end. Though authorities are confident of drawing water by gravity till May-end, nevertheless it is decided to put in place measures to take up emergency pumping.

Presently the Board is drawing 23 mgd from Osmansgar and 16.80 mgd from Himayatsagar. This quantum is expected to last another month. But as part of the contingency plan, at least four heavy pumps will be installed at Osmansagar and one at Himayatsagar so that they can be operated at a moment's notice, it is said.

The depleting ground water is a cause for worry as the demand on piped supply has gone up. Consequently the number of tanker trips to tail-end areas has increased but this is not considered a solution.

“Diverting water through tankers is not going to solve the problem. There is need to maintain balance between piped water supply and supply through water tankers”, said Adhar Sinha, Managing Director, HMWSSB.

The piezometers installed by the Ground Water Department shows that the water-level has fallen in all the 12 locations of Ameerpet, Asifnagar, Bandlaguda, Charminar, Marredpally, Nampally, Shaikpet, Himayathnagar, Musheerabad and Saidabad mandals.

Deficit rainfall

On account of the deficit rainfall of 27 per cent during the current water year, the net fall of district average water-level from March 2011 to March 2012 is -2.08m. Besides the run off due to concretisation has led to less percolation of rainwater, it is said.

The situation is no better in the neighbouring Ranga Reddy district.

Close monitoring of the ground water regime through a network of 37 piezometers installed here show the water fall ranging from 0.44 m to 10.72 m.

During 2011-12 Ranga Reddy received 32.84 per cent deficit rainfall and this clearly reflected in all the piezometers recordings.

The fall in water levels at Ghatkesar, Keesara is (-5.60 m), Medchal (-3.64 m), Manchal (-3.95 m), Moinabad (-8.14 m), Malkajgiri (-10.76 m), Shahbad (-6.88 m), Pargi (-6.32 m), Shamshabad (-4.61 m), Vikarabad (-9.16 m), Nawabpet (-3.79 m), Bantawaram (-6.96 m).
