Frequent Rain Improves Groundwater Level in Chennai

The frequent rain since June has improved the groundwater level in the city. Barring Ambattur, the groundwater table has improved across the city in August when compared to the previous month. As per Metrowater’s groundwater table data, there is a positive overall increase of 0.62 meters. The Met Department data shows that the city has received 544.7 mm since June, a 66% excess, according to a Metrowater official.

Thiru-Vi-Ka Nagar recorded the highest increase of ground water table, which is at 1.74m. This is followed by Kodambakkam, which recorded 1.41 meters. Ambattur area saw a dip in water table by 0.70m. In July, water was available at 6.31m. This has gone down to 7.01m in August. It is a shallow area and a little drawing of water can also prevent recharging. Sustained supply of piped water could be another reason for the better groundwater table level. Metrowater had scaled up its daily supply, to 1,038 mld this year.

With the completion of trial runs in a few added areas, Metrowater had started the regular supply in the suburbs located between Alandur and Tambaram. Many residential localities in the added areas were dependent on groundwater. Now, with Metrowater providing piped supply every day, those dependent on groundwater are not drawing it. According to hydrogeologist J Saravanan, who is a consultant for digging bore wells, companies are not getting many calls since June. “Groundwater table will be good in Chennai for the next two years,” he said.
