Six months after the British occupied Jerusalem, following the Battle of Jerusalem in December 1917, work started on the building a water supply system from the Al-Arroub springs, a 4-inch pipe was laid to a water pool in Romema in West Jerusalem. The company started working on the Ein Farah Waterworks project in April 1926. But the amount of water supplied was not sufficient for the needs of the growing city. In February 1926 the British company Sir John Jackson Ltd. acquired the concession to supply water and electricity to the city from Euripide Mavrommatis.
