The water-distribution system in Syria is important for the region's success as a centre of civilisation. The availability of running water nourishing both private houses and public buildings is tribute to the ancient Damascene heritage of irrigation and underwater canals that survives to this day. One of Damascus's most famous neighbourhoods is known as 'Hayy al-Qanawat' after the Roman water canals that supplied it, and which were well maintained under Islamic rule.
During the period of prolific construction begun by Nur al-Din Mahmud bin al-Zangi (d. AH 569 / AD 1174) Damascus was renowned for its luxurious bathhouses (hammams), its public drinking fountains(sabils), andthe accessibility of running water within its mosques, madrasas and hospitals (bimaristans).The water fountain and running stream attached to the courtyard basin at the Madrasa Nuriyya, built in AH 563 / AD 1167–8, is an example of the Nuri creativity in water provision, for this visible abundance of water was a mark of good governance.
The Barada River is the main water source, springing from the Anti-Lebanon Mountains near the Zabadani district at an altitude of 1100 m. Water reaches Damascus via six main channels, although the total tributaries are around 40. The underwater canals of Syria have been ingeniously used throughout history to transform a dry and desert-like region into a green one.
There is a system of water distribution in the city called a tali', which distributres a share of water to each neighbourhood based on a unit known as a qirat. The qirat is a unit of measurement equalling 1 out of 24. The total water supply in a tali'' is therefore 24 qirats and, as stated in the lease of any given property, each building has the right to a ratio of this water allocated by the tali system and measured as a number of qirats. This system of water distribution withan an urban setting was the hallmark of Atabeg and Ayyubid Damascus. Hammam Nur al-Din, for example, was constructed adjacent to its tali' and the Madrasa Adiliyya is located near Hayy al-Sabi' Tawali', a neighbourhood named after the seven tali's supplying it.
The official controller who oversees the distribution process is known as al-faradi, an aqua-specific counterpart to the muhtasib who ensures that water distribution is fair and legal. As a result of this tali' system, water from the Barada River reaches every home; the Demascene home, unlike any other, is known to this day for its central courtyard basin and sprinkling fountain, the sight and sound of water always symbolic of good living.
Similarly, in Aleppo, there is an important system of channelled water distribution known as al-qastal. The Madrasa al-Shu'aybiyya, built by Nur al-Din in AH 545 / AD 1150 was erected next to the Qastal al-Shuaybiyy which still carries his inscription and marks the extent of his work in water distribution. Also, the city of Hama is famous for its waterwheels or norias, a number of which were built during Nur al-Din's reign.

View Short Description

The supply of water for the city of Damascus relies on the River Barada, which springs from the Anti-Lebanon mountain range and reaches Damascus via six main channels and numerous minor ones. The expert manipulation of these precious waters to ensure water supply for every public institution and private house of the city was the hallmark of the rule of Nur al-Din Mahmud bin Zangi (d. AH 569 / AD 1174). Each neigbourhood was equipped with a tali' through which water was measured and distributed to the surrounding properties.
