 As farming ceased to be a viable way of life, the Zabbaleen faced economic hardships which prompted them to migrate to Cairo in search of work.Henceforth, the Wahiya collaborated with the Zabbaleen, who purchased waste from the Wahiya for use as fodder for pig farming.Initially, the Zabbaleen settled in the Imbaba district of the Giza governorate, but were given a four-day eviction notice from the governor of Giza in 1970.
