Current excavations at Shringaverapura, in Uttar Pradesh, have brought to light a huge, well-preserved water tank about 800 feet long. At its widest point, the tank is about 60 feet wide and 12 feet deep. The entire complex in brick-lined and includes a large settling tank for water diverted from the River Ganga. During the dry season, additional water was supplied from a series of dug wells. This immense system of channels, walls, access stairways, etc. is about 2,000 years old.
