City faces extreme groundwater depletion with abysmal levels recorded in Bachupally and Ameerpet

Bachupally and Ameerpet show the most severe groundwater depletion in the city. Bachupally, in Medchal-Malkajgiri district, has the State’s lowest reported GWDI score, at -2.7. Ameerpet follows at -1.7. Both fall far below the threshold for extreme drought, which is a GWDI below -0.6.

The crisis extends across many city mandals. Saidabad, Golconda, Rajendranagar, Asifnagar, Secunderabad, Bandlaguda, Bahadurpura, Amberpet, Ghatkesar, Medipally, Kukatpally and Hayatnagar are also classified as extreme drought areas. Their GWDI scores range from -0.64 to -1.15.

Five more mandals—Khairatabad, Balanagar, Qutbullahpur, Gandipet and Abdullapurmet—are in the severe drought category. These figures show that the problem is not limited to one locality. Four months before summer, much of the Core Urban Region is already experiencing unusually deep groundwater levels.

The Groundwater Drought Index, or GWDI, classifies mandals by comparing their current groundwater depth with historical groundwater behavior. It places areas in five categories: normal, mild drought, moderate drought, severe drought and extreme drought. This helps officials identify where groundwater conditions have deteriorated most sharply.

The calculation uses the difference between the historical mean depth and the current month’s depth, divided by the historical maximum depth for that month. A score above -0.15 is normal. Scores from -0.16 to -0.3 indicate mild drought, while scores below -0.6 indicate extreme drought.

A very negative score signals that groundwater is much deeper below the surface than usual. Bachupally’s -2.7 and Ameerpet’s -1.7 therefore indicate exceptional depletion. The index matters because it compares places against their own historical patterns, rather than relying only on one month’s water-table measurement.

Ameerpet recorded the State’s deepest groundwater level in September 2026, at 32.07 metres below ground level. That was more than twice its previous September maximum of 13.36 metres, measured across the preceding ten years. The comparison shows how far the water table had fallen beyond its earlier range.

Bachupally recorded groundwater at 30 metres below ground level in the same month. Its previous September maximum was 9.06 metres. The 2026 depth was therefore more than three times that historical maximum. This extreme difference helps explain Bachupally’s exceptionally low GWDI of -2.7.

These measurements describe depth below the land surface, not the total volume of water underground. Greater depth means wells must reach farther to access groundwater. With summer still four months away when the figures were reported, the unusually deep levels indicated a serious warning for water availability in both mandals.

The groundwater crisis is widespread across Hyderabad’s Core Urban Region. At least fourteen mandals were classified as facing extreme drought based on groundwater depth. Five additional mandals were placed in the severe drought category. Together, these figures show that the problem reaches well beyond Bachupally and Ameerpet.

The fourteen extreme-drought mandals include Bachupally, Ameerpet, Saidabad, Golconda, Rajendranagar, Asifnagar, Secunderabad, Bandlaguda, Bahadurpura, Amberpet, Ghatkesar, Medipally, Kukatpally and Hayatnagar. The five severe-drought mandals are Khairatabad, Balanagar, Qutbullahpur, Gandipet and Abdullapurmet.

Across the whole State, 33 mandals had GWDI scores below -0.6, meeting the definition of extreme drought. The Ground Water department tracks conditions through 1,771 monitoring stations across 621 mandals in 33 districts. This network provides the measurements used to assess the crisis at both city and State levels.

If groundwater continues falling before summer, residents may find that shallow wells and borewells no longer provide dependable water. Deeper water tables can also make pumping more expensive because equipment must lift water farther. In areas already facing unusually deep levels, households may experience interruptions or need alternative supplies.

Farms could face reduced irrigation, especially where groundwater is a main source during dry periods. Less available water can limit planting, lower yields and increase competition among users. These consequences are general implications of continued depletion; the article itself reports groundwater levels and drought classifications, not specific crop or household impacts.

Cities may face wider shortages if demand rises while local aquifers recover slowly. Public agencies could need to bring water from other sources, restrict use or expand monitoring. The report’s timing is significant: it describes acute groundwater stress four months before summer, when pressure on available water may increase.

Groundwater depletion is measured by recording the depth from the land surface down to the groundwater table. The Ground Water department collects these readings monthly through 1,771 monitoring stations, called piezometers. The network covers 621 mandals in all 33 districts and includes different geological settings and aquifers.

The GWDI compares the current month’s depth with historical values for that same month. Its formula uses the historical mean depth, the current depth and the historical maximum depth. The department calculates the historical figures from the previous ten years. This creates a local baseline rather than treating one depth as equally severe everywhere.

That comparison matters because groundwater depth naturally varies between places and seasons. A reading that is ordinary in one mandal may be alarming in another. In September 2026, Ameerpet reached 32.07 metres below ground level, compared with a previous September maximum of 13.36 metres. The index captures that unusual change.

The source article does not describe how groundwater moves through aquifers or how recharge occurs. In general, aquifers are underground layers of permeable soil, sediment or rock that store and transmit water. Groundwater usually moves slowly through connected pores and fractures, following pressure and elevation gradients toward springs, rivers, wells or the coast.

Recharge happens when water from rain, rivers or other surface sources infiltrates the ground and reaches the aquifer. Cities can withdraw water faster than natural recharge when pumping for homes, businesses and farms exceeds the amount entering underground storage. Paved surfaces can also reduce infiltration by carrying rainwater away, while drought or intense development can limit replenishment.

When withdrawals remain higher than recharge, the water table falls and wells must reach deeper. The article reports this pattern in Hyderabad, including depths of 30 metres in Bachupally and 32.07 metres in Ameerpet during September 2026. Those readings show severe depletion, although the source does not identify its exact causes.
