Electric pumps are used to draw water from the well, replacing the ropes and buckets of the olden days. No visitor is allowed to enter the Zamzam Well room and surroundings. Outside this room, there was a service area, where cold Zamzam water fountains and dispensing containers were provided for drinking purposes. Recently, the Al-Haram Tawaf area has been extended to cover the entrance to this area and it is no more accessible to pilgrims. Instead, cold Zamzam water fountains and dispensing containers are now placed at the periphery of Tawaf area and within the Grand Mosque, and open piazzas or Al-Sahat surrounding the Al-Haram building Moreover, a bottling plant and public distribution Sabeel have been established at Kudai, south of Al-Haram for the visitors who want to carry Zamzam home.
The upper 13.5 m of the well is excavated in the sandy alluvium of the Wadi Ibrahim, and the lower 17.0 m in the underlying diorite bedrock. In between lies a 0.5 m thick highly permeable weathered rock. Most of the alluvial section of the well is lined with stone masonry except for the uppermost 1 m, which has a reinforced concrete collar. The weathered rock section is lined with stone and it is this section that provides the main water entry into the well.
