The Building of The Hydraulic System in Madrid (Spain) in The Middle Ages

At the end of the Middle Ages, the city of Madrid had a perfect system of water supply to the population formed by a wide network of “qanats” or “viajes de agua” (water trips). This network improved and spread as the same time as the city and its needs. The city subterranean water sources proved to be insufficient and it was necessary to look for new ones more distant and remote. New “water trips” were, therefore, needed. This water supply system was in constant renewal, and it was still until today, where the actual system is the descendant of the primitive constructions. The original construction basis of the primitive system has been maintained, taking always account of the innovation of the building techniques, the current water needs and the care of environment.
