EPC Project of Utility System of Desalination (SWRO)

The object of this project is to develop a utility system to support sea water desalination plant (Sea Water Reverse Osmosis, SWRO) at the Sea Water Intake System (SWIS) in AMNT.

Scope :

  • Fresh water storage tank with capacity 2,500 MT
  • Pumping system, including electric power supply & instrumentation
  • 12” and 14” HDPE pipelines for sea water, brine and fresh water
  • Civil concrete structure, containment, and drainage system
  • Electrical panels & cable trays
  • Lighting system

This project functions to supply sea water to the desalination plant located at the SWIS area. It also transfers fresh/product water to a freshwater storage tank and discharges brine water to the sea wall connected to the tailing line. The pumping station is equipped with a redundancy configuration and is installed within SWIS desalination plant area.
