The low-level aqueduct which, though out of repair, can still be followed along its whole course, conveyed water from three great pools in the Wady ?Artas, 7 miles South of Jerusalem. They are usually called "Solomon's pools," in reference perhaps partly to
Ec 2:6: "I made me pools o water, to water therefrom the forest where trees were reared," but as any mighty work in Palestine is apt to be referred to the wise king of Israel, much stress cannot be laid on the name. These three storage reservoirs are constructed across the breadth of the valley, the lowest and largest being 582 ft. long by 177 ft. broad and, at the lowest end, 50 ft. deep. Although the overflow waters of ?Ain es Saleh, commonly known as the "sealed fountain" (compare
So 4:12), reach the pools, the chief function was probably to collect the flood waters from the winter rains, and the water was passed from tank to tank after purification. There are in all four springs in this valley which supply the aqueduct which still conveys water to Bethlehem, where it passes through the hill by means of a tunnel and then, after running, winding along the sides of the hill, it enters another tunnel now converted into a storage tank for Jerusalem; from this it runs along the mountain sides and along the southern slopes of the site of Jerusalem to the Charam. The total length of this aqueduct is nearly 12 miles, but at a later date the supply was increased by the construction of a long extension of the conduit for a further 28 miles to Wady ?Arrub on the road to Hebron, another 5 miles directly South of the pools. Here, too, there is a reservoir, the Birket el ?Arrub, for the collection of the flood-water, and also several small springs, which are conducted in a number of underground rock-cut channels to the aqueduct. The total length of the low-level aqueduct is about 40 miles, and the fall in level from Birket el ?Arrub (2,645 ft. above sea-level) at its far end to el Kas, the termination in the Charam Jerusalem (2,410 ft. above sea-level), is 235 ft.
