Water and culture
Water and culture is the theme of this year's World Water Day (March 22). Invariably, all old temples, big or small, have tanks in the city. Though there is a religious purpose, the tanks are among the earliest rainwater harvesting structures. Over the years, some of them went into disuse. Because of acute water shortage, steps were taken by authorities to make temple tanks serve the purpose of RWH. Tanks of the Marundeeswarar temple, Thiruvanmiyur, and the Dhandeeswarar temple, Velachery, were among those that were renovated.
As Thiruvanmiyur is a sandy area, the tank does not appear to have water. But, the picture is different in the case of the Dhandeeswarar temple tank, which has water. The main reason is Velachery is a hard rock area.
However, as the tanks were renovated, they have contributed to the improvement in groundwater table in the two areas.
