Possibly the “narrow well” with the “steaning wall” only 11 inches thick, in Mound F trench A (e), which Sahni reported from the lowest excavated strata, and which he inferred was connected to the “reservoir” excavated in 1923-24:

“In mound F which rises about 25' above the plain level, a large area (Ae) has been dug along the Western edge of the site. The structural remains exposed range themselves in four distinct strata. The uppermost stratum yielded, besides a number of fragmentary walls, a well preserved sepulchre constructed with burnt bricks of the usual size and lying cast to West. … The fragmentary brick walls that came to light on the second stratum call for no special remarks. … On the next lower stratum special interest attaches to a solidly built corner of a dwelling house …To the north of this structure the excavations revealed another funeral structure …The next or the lowest stratum reached in this area (Ae) lies at the depth of 8' below the surface, and is occupied by a very narrow well with the inner diameter of 2' 2'', the steaning wall being only 11" thick. It was cleared to a depth of 8' and though it has so far yielded no objects of interest, it is now evident that the brick reservoir with its drain which was brought to light near this spot in 1923-24 must have belonged to this well and been used for the storage of water for ablutions, etc. The portable antiquities found in this trench included a conch spoon (Plate XXVII, e) which may have been used for pouring out libations to the manes, a tiny corroded copper disc (Ae. 33a) which might have been a coin, a small headless figure (Ae. 6) seated on a chair in the fashion of a Sumerian king and a bone awl or needle (Ae. 253), 5 ½” long.

Vats described the well to be “small”, 1 ft 10 inches, and noted:

“The Illrd stratum [in trench Ae] is represented in the northern portion by a small well 1 ft. 10 in. in diameter with brick-on-edge steening, by a fine pavement of chiselled and well-rubbed bricks, and by a drain which pours itself on the west into a 2 ft. 4 in. square paved sink for the storage of used up water (PI. X, b). In the central portion may be noticed a fairly well built corner of a large room with a covered drain, another broken drain to its west, and, to its south, two more walls in squares H 10/7 and H 10/12. In the southern portion there is a covered drain in square H 10/3.”
