Aqueduct in Xemxija Malta
In 1839, the British built an aqueduct allowing the transportation of water. The water travelled from an underground aqueduct in an area in Wardija, known as tal-Ballut, that extends to an above ground aqueduct and then to a reservoir both in Xemxija. The conservation of water was needed for the British military and their horses, who surveilled the area from the nearby defence posts (Wikipedia)
