‘We should not use groundwater for the next 15/20 years’

The depletion of groundwater table in Dhaka has made water crisis in the city acute, especially during the dry season. What are the reasons behind this? We have conducted many research studies in the last 15/20 years and have found that Dhaka's groundwater table has been gradually depleting at an average rate of one metre or 30/40 centimetres sometimes. Because of the rapid urbanisation of the city, the demand for groundwater has been increasing. In the multi-storied buildings and towers that are being constructed, high-powered pumps are used to extract water from underground. This contributes significantly to the lowering of the groundwater table. In Dhaka, there is no water in the shallow aquifers (50-70 feet deep). Presently, water is being extracted from the intermediate and deep aquifers, which are 600 to 800 feet deep.
