Report : Pipeline transport of solid waste in the Grand Holy Mosque in Makkah

摘要

The Grand Holy Mosque, located in the Holy City of Makkah in Saudi Arabia, attracts millions of Muslim visitors from all over the world, especially during the pilgrimage season. The daily amount of refuse generated in the Grand Holy Mosque and surrounding plazas reached a maximum value of 192.8 tons/day in 1998. Collection and transport of the solid waste generated during the peak times present a challenge to the Makkan authorities. The congested streets and high population density in the Holy Mosque and its surrounding plazas make the traditional methods of collecting and transporting solid waste impractical. This paper presents an alternative system for the collection and transport of solid waste generated in and around the Grand Holy Mosque in Makkah. The proposed system is based on a pneumatic transport technique, by which the waste is collected and transported in underground pipelines. A conceptual layout of the proposed system in the Mosque area is presented, and the merits of the suggested system are discussed.
