Faced with water shortage, residents of the semi-arid Kerio Valley in Elgeyo Marakwet devised an igneous way to draw water up the highlands passing through the rugged terrain down to their homes in furrows.
The furrows drop down the escarpment to the valley, supplying water to farms. The art has stood the test of time and defied modernity. Some furrows are claimed to have been constructed centuries ago.
