A diagonally running retention wall crossing the N-S oriented wadi is just barely made out in the stereoscopic aerial image, though hardly in the field. The wall served to collect water in a cistern, preserved in the form of a large hole to the N of the Hafir. When the cistern was full, the overspill flowed into the Hafir with its two, different-sized basins. One also recognises an inlet at the outside of the southern Hafir wall. Water was thus probably stored as follows: The northern basin and the cistern were filled with water derived by the retention wall of the main wadi, while the southern basin bordering on it was filled with rainwater from the side wadi through the inlet on the eastern side of the compound.
Occasional, still occurring floods today follow the same course as can be told by the sludge deposits inside and outside the compound. The size of the reservoir points to the enormous needs for water engendered by the wadiworkings. Indeed, almost all wadi courses in the district of Umm Garaiyat exhibit visible traces from intensive wadiworkings (Fig. 5.258).
