From the coast to the interior

The Shuquaiq Phase 3 project will implement five water conveyance systems to transport drinking water from the new desalination plant at Baysh Dam to the areas of Abha, Samta and Jizan, and along the route to Mahayil and Majardah. Following design and planning from 2018 to 2020, the project will be launched in 2020.These five pipelines include:

  • 328 km of steel pipelines (ø 12" to ø 80") with a total flow of 7.5 m3/s, a cumulative head of more than 4000 m and a maximum elevation of 2330 m ASL.
  • 140 km of 48" to 64" gravity fed pipes
  • 4 tunnels lines laid in the existing tunnel (Shuqaiq Phase 2)
  • 9 new pumping stations (with fixed and/or variable speed pumps)
  • 4 storage stations with a capacity of up to 3 x 140,000 m3
  • 9 branches to tank truck filling stations
  • Staff accommodation for all stations
  • Maintenance centres and service buildings at the pumping stations
  • Control and automation

The whole system is controlled by a modern remote monitoring system, which allows automatic and centralised operation.

Pipelines, pumping and storage stations are often built in difficult, steep terrain, requiring special construction and stabilisation measures. Without appropriate precautions, rare but extreme flash floods can also cause severe damage.

 

Preparation of the execution phase (final design)

In close cooperation with the construction consortium, HOLINGER carried out the following tasks:

  • Hydraulic analysis and wall thickness determination reports
  • Operational concept
  • Process and instrumentation diagrams
  • General plans for pumping and storage stations
  • Construction drawings for pump houses, surge tanks, electrical buildings, etc.
  • Construction planning for all buildings and structures
  • Reviewing the mechanical, electrical, control and hydraulic systems
  • Evaluation of the connection to the existing Kheyalah pipeline
  • Evaluation of the connection to the existing Baha pipeline

Evaluation of a return flow scenario from PSA1 to the Arafat-Al Moghamas reservoirs
