Definition
Aflaj (singular: falaj) are traditional irrigation channels that have been used in Oman for thousands of years to transport water from underground sources or mountain springs to farms and settlements through gravity-fed channels. The system requires no mechanical pumping and is considered one of the most sophisticated ancient water management technologies in the world. In 2006, five aflaj systems in Oman were inscribed as a UNESCO World Heritage Site under the title Aflaj Irrigation Systems of Oman.
Context in Oman
Oman has more than 4,000 documented aflaj, of which roughly 3,000 are still in use. The three main types are dawoodi (underground tunnel falaj that taps the water table), ghaili (surface channel falaj that diverts wadi flow), and aini (spring-fed falaj). The longest aflaj can extend over 12 kilometres. Management of each falaj is governed by centuries-old customary law, with a wakil al-falaj (falaj manager) responsible for water allocation, maintenance, and dispute resolution among farmer-shareholders. The aflaj represent not just engineering but an entire social and legal system for communal water governance.

Vision 2040 Connection
Vision 2040 environment pillar emphasises sustainable water resource management. While modern desalination and dam infrastructure handle urban and industrial needs, the aflaj remain vital for traditional agriculture and represent living cultural heritage. The strategy supports aflaj preservation and restoration as part of both agricultural sustainability and cultural tourism development.
