An ancient Water supply system of 2000 year old was unearthed on 25 May 2015 in the city of Jerusalem, Israel.
According to the Israel Antiquities Authority, a section of Jerusalem's Lower Aqueduct, which conveyed water to the city more than 2000 years ago, was exposed in the Umm Tuba quarter. The supply system was unearthed during the construction of a sewer line.
The aqueduct begins at the En 'Eitam spring, near Solomon's Pools, south of Bethlehem, and is approximately 21 kilometres long. Despite its length, it flows along a very gentle downward slope whereby the water level falls just one meter per kilometre of distance.
At first, the water was conveyed inside an open channel and about 500 years ago, during the Ottoman period, a terra cotta pipe was installed inside the channel in order to better protect the water. The aqueduct's route was built in open areas in the past, but with the expansion of Jerusalem in the modern era, it now runs through a number of neighbourhoods: Umm Tuba, Sur Bahar, East Talpiot and Abu Tor.
Since this is one of Jerusalem's principal sources of water, the city's rulers took care to preserve it for some two thousand years, until it was replaced about a century ago by a modern electrically operated system.
Due to its historical and archaeological importance, the Israel Antiquities Authority is taking steps to prevent any damage to the aqueduct, and is working to expose sections of its remains, study them and make them accessible to the general public.
