So far there are only two pieces of evidences for water transport - one on a seal and another a potsherd. This is a trapezoidal brick structure measuring 710' × 124'. It is rivetted on all four sides with a continuous dry masonry burnt-brick wall, 4 courses wide, which at its greatest extant depth reaches to 14 ft, (but might have been originally much higher). The structure was stratigraphically connected to the old river-bed of Sabarmati.
