Metrowater concerned over indiscriminate digging of borewells

By Our Staff Reporter

CHENNAI, APRIL 14. Concerned over indiscriminate digging of deep borewells all over the city, Metrowater has recommended the maximum depth for new borewells in different parts of the city.

Based on lithological formation, the agency has categorised the entire city into five regions. The regions are southern coastal aquifer belt, areas with alluvial/sandy formation adjacent the coast, areas with clay formation, areas with clay and sand mixed formation, and areas with hard rock formation.

The recommended levels for the five areas are mentioned as follows. Metrowater, in a press release issued on Thursday, appealed to the residents to keep new borewells less than the suggested levels to safeguard the precious groundwater resources.

Acknowledging that the groundwater table depleted at a faster rate due to the failure of two successive north-east monsoons, the water agency said the average summer water level during the normal period ranged from 9 ft to 15 ft. Now, it stood at 20 ft.to 40 ft.
