The Yanbu-4 IWP project is a 450,000 m³/day seawater desalination plant

It is located near the town of Ar Rayyis, on the Red Sea coast and will use a reverse osmosis process and technology to supply potable water to the cities of Makkah and Medina


Work under the project consists of:

  • analyzing background information (marine climate, bathymetric and geotechnical marine survey data, sea-bed data, etc.),
  • conducting preliminary metocean studies and a study to determine the best technical solution for the plant (seawater intake and brine outfall location, diffuser type, seawater pumping, etc), including far-field dilution modelling using TELEMAC-3D,
  • designing intake towers and pipes, anchors, ditches and ballast,
  • making calculations (pipes, flotation and stability, seawater pumping and discharge chambers) and preparing the Bill of Quantities related to marine works.
