On Zubaidah bint Ja`far ibn Mansur fifth pilgrimage to Mecca, she saw that a drought had devastated the population and reduced the Zamzam Well to a trickle of water. She ordered the well to be deepened and spent over 2 million dinars improving the water supply of Makkah and the surrounding province. This included the construction of an aqueduct from the spring of Hunayn, 95 kilometers to the east, as well as the famed "Spring of Zubayda" on the plain of Arafat, one of the ritual locations on the Hajj. When her engineers cautioned her about the expense, never mind the technical difficulties, she replied that she was determined to carry out the work "were every stroke of a pickax to cost a dinar", according to Ibn Khallikan. She also improved the pilgrim route across nine hundred miles of desert between Kufa and Mecca. The road was paved and cleared of boulders and she assembled water storages at intervals. The water tanks also caught the surplus rainwater from storms that occasionally drowned people.
