Centuries old aflaj irrigation system in Oman

Oman's ancient aflaj irrigation systems, some dating back 2500 years, remain highly efficient and integral to village life despite modern advancements. These systems tap groundwater near mountains, channeling it through a network of mother wells, access shafts, underground tunnels, and surface channels—supported by structures like aqueducts and siphons—to create oases. With an estimated 3000 active networks, aflaj play a significant social role, maintained by village cooperatives with historically rich water rights and distribution practices. Recognizing their cultural and engineering significance, UNESCO designated five key aflaj as World Heritage Sites in 2006.
