Gabal el-Asfar, also known as the 'Yellow Mountain,' is a prominent elevation located northeast of Cairo at the edge of the Nile Delta. Today, the region is primarily known for its extensive wastewater treatment infrastructure, hosting one of the largest sewage treatment plants in Africa and the Middle East. Historically, the area was a barren desert landscape with shifting sand dunes that gave the mountain its name. Due to the availability of reclaimed water, large portions of the surrounding land have been reclaimed since the early 20th century for forestry experiments and agricultural projects. This has led to the creation of woodlands and plantations in the middle of the desert, serving as a green lung for the expanding Cairo metropolitan area. Geologically, the hill consists of Tertiary sediments and sandstones. Despite the industrial nature of the treatment facilities, Gabal el-Asfar remains an intriguing example of the transformation of desert land into productive green space through modern engineering.
