Two tanks attached to the Sri Trivikrama temple in Tirukkoilur in Kallakurichi district used to brim with storage even in the heights of summer and helped in recharging the ground water level in the area. The tanks served as the venue for the annual float festival but now they have fallen into disuse.
The temple has two tanks, one near the main entrance and the other situated close to the Raja Gopuram. The tanks received continuous supply of water from the nearby Santhapettai lake, thanks to an underground canal.
The underground canal submerged in the lake, believed to be built during the Nayak period, is supported on all sides with granite slabs. The 1-km long canal was an ancient method of water management and was equipped with a constant supply of fresh water from the lake to the two tanks.
