Tamil Nadu faces critical water shortages as reservoirs and groundwater levels drop

Tamil Nadu is facing a severe water crisis as reservoir storage levels and groundwater tables drop significantly due to rainfall deficits. Data from the Water Resources Department indicates that 63 of the state’s 90 reservoirs are currently holding less than 25% of their capacity. The combined storage across all reservoirs stands at approximately 33.17%, a sharp decline from the 80.94% recorded during the same period last year.

In the Chennai region, the situation is compounded by depleting groundwater in suburban areas such as Pallavaram, Chromepet, and Velachery. While core city areas maintain relatively healthy groundwater levels due to piped water supplies, suburban residents relying on deep borewells are seeing water tables fall between 300 and 700 feet. This depletion is attributed to high demand from multi-storey apartments and domestic usage.

The state is now heavily dependent on the upcoming northeast monsoon to replenish reservoirs and meet drinking and irrigation needs. Officials noted that the shortage is particularly acute in western Tamil Nadu and the Coimbatore region, where most reservoirs are below 40% capacity.
