A severe rainfall deficit of nearly 48% and unchecked borewell extraction have caused Visakhapatnam's water table to drop significantly, with several villages crossing the 20-metre depth mark.
- Groundwater level dropped from 7.65m (Aug 2025) to 11.51m (Aug 2026).
- District recorded a massive 47.89% rainfall deficit.
- 6 villages have groundwater depths exceeding 20 metres.
- Urban concrete cover is blocking natural recharge of aquifers.
The water table in the Visakhapatnam district has witnessed a sharp decline of 3.86 metres within a single year. According to data from the District Ground Water and Water Audit Department, the average depth increased from 7.65 metres below ground in August 2025 to 11.51 metres in August 2026.
District Ground Water Officer K. Pushpalatha attributed this precipitous fall to an acute deficit in rainfall. During a training programme organized by the Central Ground Water Board (CGWB) and the GITAM School of Science, it was revealed that the district recorded only 92.39 mm of rain against a seasonal normal of 177.3 mm—a deficit of 47.89%.
Why This Matters
BozokMedia analysis suggests that Visakhapatnam is facing a systemic failure in water management. The synergy of climate-induced rainfall deficits (linked to El Niño) and anthropogenic factors—such as the proliferation of concrete surfaces in urban wards—has created a scenario where water cannot penetrate the soil. This 'urban sealing' effect, combined with aggressive borewell pumping for industrial and domestic use, is depleting the aquifers faster than they can recover.
"El Niño’s influence on the monsoon led to below-average rainfall across India, causing poor groundwater recharge across several parts of Visakhapatnam district this year." - P. Kiran Kumar, CGWB Scientist.
The severity of the situation is highlighted by real-time data from 31 piezometers and eight observation wells. The report indicates that six villages have now hit a critical depth of over 20 metres. Furthermore, 135 habitations, including 96 rural villages and 39 urban wards, are struggling with water levels between 6 and 20 metres.
Environmental experts, including those from GITAM, have raised alarms regarding seawater intrusion. In coastal cities like Visakhapatnam, as the freshwater pressure in aquifers drops, saline water from the ocean begins to seep inland, potentially contaminating the remaining potable groundwater sources permanently.

Frequently Asked Questions
1. What are the primary causes of the groundwater drop in Visakhapatnam?
The drop is caused by a significant rainfall deficit (approx. 48%), excessive extraction via borewells, and urban concrete cover preventing rainwater from recharging the soil.
2. How does seawater intrusion happen?
When freshwater levels in coastal aquifers drop, the hydraulic balance is disrupted, allowing denser saltwater from the sea to migrate into the freshwater zones.
