Groundwater levels in and around Hyderabad plummet by one metre in one month

“Metres below ground level,” or m bgl, measures the vertical distance from the land surface down to the groundwater level. A smaller number means water is closer to the surface. A larger number means it is deeper underground and harder to reach.

In September, the average groundwater level across the three municipal corporations was 11.58 m bgl. In October, it was 12.59 m bgl. Although the article describes this as groundwater falling, the measurement increased because the water table moved downward by 1.01 metres.

This matters because existing borewells may no longer reach water as easily. Pumps may need to operate from greater depths, and new borewells may need to be drilled deeper. The change followed a 34% rainfall deficit from June through October, while illegal extraction also raised concerns.

Across GHMC, CMC and MMC, groundwater levels moved from 11.58 m bgl in September to 12.59 m bgl in October. That is a 1.01-metre decline in one month. The figures show that groundwater conditions varied sharply between locations rather than changing uniformly.

Kukatpally recorded the deepest level, at 22.88 m bgl. Shaikpet recorded the shallowest, at 2.35 m bgl. The difference between them was 20.53 metres. The Telangana Ground Water Department collected these readings through 107 piezometers, instruments used to monitor groundwater levels.

Deeper water levels of more than 20 m bgl covered nearly 12% of the corporations. The affected areas included parts of Hyderabad, Medchal-Malkajgiri and Rangareddy districts. These measurements point to particularly difficult groundwater access in several urban and peri-urban zones.

When groundwater lies deeper, a borewell may no longer reach it efficiently. Pumps must lift water from a greater depth, and some wells may need deepening or replacement. That can increase costs and energy use, although the article does not quantify either change.

Households depending on borewells could experience reduced access or greater uncertainty, especially where levels are already more than 20 m bgl. Tanker operators may also struggle to find nearby legal sources. The article reports complaints about borewells extracting water 600 to 1,000 metres near waterbodies.

Following a protest and meeting with HYDRAA, Hyderabad’s Water Tankers Association agreed to collect borewell water from the Peri Urban Region outside the Outer Ring Road, after obtaining required permission. This may shift tanker collection away from stressed urban waterbodies, while conservation remains important.

Groundwater is replenished when part of the rain that falls on the land filters downward through soil and rock. Below-normal rainfall means less water is available for this natural recharge. If dry conditions continue, groundwater levels can fall as people keep using stored underground water.

The article reports 484 mm of rain from June 1 to October 31, compared with a normal 729 mm. That was a 34% deficit. Six of the 46 mandals within the urban limits received normal rainfall, while 40 recorded deficits between 21% and 51%.

Extraction can deepen the problem when wells remove water faster than rainfall replaces it. The article links concerns to illegal borewells near waterbodies and to possible shortages in coming months. It also notes concern about the impact of El Nino weather phenomena, making conservation and controlled pumping more important.

The Telangana Ground Water Department monitors groundwater across GHMC, CMC and MMC. Its October report used readings from 107 piezometers. The report identified a monthly decline and mapped areas with especially deep groundwater, giving officials evidence about changing water conditions.

HYDRAA removed borewells near waterbodies, including Sunnam Cheruvu and Fox Sagar lake. It also received complaints about illegal borewells extracting water near waterbodies. After a protest and meeting with HYDRAA Commissioner A.V. Ranganath, the Water Tankers Association agreed to collect permitted borewell water from the Peri Urban Region outside the Outer Ring Road.

HMWSSB acted against people attaching motors illegally to drinking-water pipelines. It warned of penalties for washing vehicles, floors or otherwise wasting drinking water. Its PAANI app lets people register as water warriors and report water wastage. The Board also promotes reuse and conservation practices.

Cities can reduce pressure on illegal or increasingly deep borewells by using permitted sources, preventing waste and reusing suitable water. The article directly points to regulated tanker collection from the Peri Urban Region outside the Outer Ring Road, rather than unchecked extraction near waterbodies.

It also gives a household example: a water warrior collected water discharged after reverse-osmosis purification and reused it for cleaning utensils and mopping floors. HMWSSB promotes such conservation and penalises wasteful uses, including washing vehicles and floors with drinking water. These steps reduce demand on drinking-water supplies.

Broader measures such as rainwater harvesting, restoring recharge areas, treated-water reuse and fixing leaks are established urban-water options, but the article does not describe local programmes for them. Their value would be to capture more water, reduce fresh demand and slow pressure on aquifers.

Groundwater is water held below the land surface in openings and cracks within soil, sand, gravel and rock. An aquifer is an underground formation that stores and allows groundwater to move. Wells and borewells access this stored water for homes, tankers and other uses.

Rainfall can replenish an aquifer when water does not run off or evaporate. It seeps into the ground through soil and permeable rock, moving downward until it reaches the saturated underground zone. This process is called recharge. The amount and speed of recharge depend on rainfall, land surfaces and underground materials.

The article connects the Hyderabad decline with a 34% rainfall deficit and concerns about extraction. It does not explain aquifer structure or recharge mechanics directly, so this explanation uses established groundwater science. In the reported area, less rainfall meant less water available to replace withdrawals.
