Dhaka's dependence on groundwater has long been an unsustainable practice, but the latest findings on the capital's rapidly falling water table make it clear that what was once a looming concern has become an urgent crisis.
With around three-quarters of the city's water still being drawn from underground sources -- despite years of plans to shift towards treated surface water -- the warning signs can no longer be ignored.
Experts have cautioned that continued over-extraction threatens the city's long-term water security, and could leave future generations facing severe shortages.
The problem extends far beyond water supply alone: A steadily declining groundwater table increases the cost of extraction, places additional strain on infrastructure, and leaves the city increasingly vulnerable to the effects of climate change and rapid urbanization.
At the same time, the unchecked expansion of concrete across Dhaka has dramatically reduced the amount of open land through which rainwater can naturally replenish underground aquifers. Adding to the challenge is the significant amount of water lost every day through leakage, waste, and inefficient consumption.
This is why immediate action is imperative.
Accelerating the construction of surface water treatment plants must become a national priority, while stricter regulation of private deep tube wells is essential to curb excessive groundwater extraction.
Rainwater harvesting should be made commonplace in both residential and commercial developments, and investments in artificial groundwater recharge should no longer remain confined to discussion.
At the same time, reducing system losses through improved infrastructure and encouraging responsible water use among consumers can significantly ease pressure on existing supplies.
Dhaka's groundwater is a finite resource, not an inexhaustible reserve. Continuing to rely on it as the city's primary source of water is simply postponing a crisis that will become far more difficult and costly to resolve.
The authorities must act with urgency before the city runs even deeper into trouble.
