HYDERABAD: Researchers of the city-based National Geophysical Research Institute (NGRI) have come out with a plausible reason for the recent gushing of groundwater in Bagh Amberpet and Nallakunta regions in the twin cities.

The researchers, who collected water samples from several colonies in Nallakunta and Bagh Amberpet, felt that introduction of round-the-clock water supply by Hyderabad Metropolitan Water Supply and Sewerage Board (HMWS&SB) could be the key reason for the strange phenomenon.

Phenomenon to recur

The preliminary report prepared by the researchers also point out that there is a possibility of the phenomenon to recur next year during rainy season and advocated proper utilisation of ground water resources in this region to avoid such situations.

It may be recalled that in September, several cellars of old and new apartments in the region were inundated with groundwater. This had also led to a brief halt in the construction activity of new apartments here. "At present the oozing has stopped to some extent although not fully. We have concluded that with the introduction of 24-hour water supply, people had stopped using the groundwater and as a result, the water table went up considerably," explained NGRI Geologist D.V. Reddy.

The researchers drew parallels of this phenomenon with oozing of groundwater in Jodhpur, Rajasthan. "There was a similar situation in Jodhpur also. The Government had introduced Indira Gandhi Canal till Jodhpur that brought ample water to the region. The locals stopped using groundwater because of this," Mr. Reddy told The Hindu . NGRI experts also found groundwater oozing up to ground level in Paamula Basthi near Amberpet confirming that residents here had reduced usage of groundwater due to 24-hour water supply.
