Since time immemorial, there have been two valleys that bestow abundant water on the people of the Fenja in agriculture and all forms of life, and they are still flowing and feeding the people and farms. One of the valleys is called the eastern falaj, and the other falaj is a western falaj. About 4 years ago, Oman'' visited Fenja and stood at the stations of the eastern falaj, which takes its visitors to a mountaintop, marching with the falaj to the point of the “ummah” which is the source of the falaj.
