Secure water supply for Mecca
The Makkah Al Moghammas Strategic Reservoir Supply project aims to provide sufficient drinking water for the city of Makkah by collecting water from two different conveyance systems into a strategically located reservoir. It consists of 72 water tanks, each with a capacity of 170,000 m³, for a total storage capacity of 12 million m³.
The two main conveyance systems to the reservoir are
- Rabigh-Jeddah/Makkah WTS: 2 x 88" gravity lines from the High Point Reservoir with a flow capacity of 1,220,000 m3 per day.
- Shoaiba-Mina WTS: 2 x 80" pressure lines with a maximum flow capacity of 1,300,000 m3 per day.
The supply of potable water from the Moghammas reservoir to the Mecca distribution network is ensured by main distribution pipelines:
- Mecca city network north: 100" line to N1, N2 and N3 stations
- Mecca City Network East: two 100" lines to the supply stations E1 and to E2, E3 and E4 through a junction station.
