Hyderabad: As the monsoon begins to withdraw, it leaves in its wake some very satisfied citizens of Greater Hyderabad.
Groundwater levels have gone up in the city. The average groundwater level was 6.27 metres on October 2 last year, which is 5.94 metres now.
The groundwater table has risen across the city — from the IT corridor of Hitec City and Gachibowli to Darulshifa and Chandrayangutta in the old city, Maredpally and Secunderabad in the new city and Uppal and Qutbullapur in the surrounding municipal circles. Urban areas of Ranga Reddy district have also benefited.
Hyderabad district recorded 15 per cent excess rainfall between June and September this year. Experts also attribute the rise in water table to construction of rainwater pits by many colony and apartments associations, and individuals besides government agencies like the GHMC and the Water Board.
The increase in ground water levels is crucial keeping in mind the lack of inflows in Osman-sagar and Himayatsagar this year.
Due to encroachments in its catchment area and the rainfall being normal there, the two reservoirs have just enough water to supply the city for four months.
If the two reservoirs do not receive further inflows hereafter, they will go dry after four months, leaving a drinking water deficit of 45 million gallons a day.
The city gets 345 MGD of water daily with 180 MGD being drawn from Krishna Phase-I and Phase-II and another 120 MGD from Singur and Manjira. About 45 MGD is drawn from Osman-sagar and Himayatsagar.
“About 80-100 MGD ground water is used by the city every day during summer. Even if Osman-sagar and Himayatsagar go dry by February, the shortage may not be felt that much due to the availability of groundwater,” said a senior official in the Water Board.
