Southern Seawater Desalination Plant

Southern Seawater Desalination Plant 
ML/day seawater desalination plant
Office: Perth 
Customer: Water Corporation 
Location: Binningup, Western Australia 
Timeframe: 2009 – ongoing 
The Southern Seawater Desalination Project involved the delivery and design of a 320 ML/day seawater desalination plant.

Particular features of this plant were the high focus on operational aspects and sustainability. 

Project services

The project was delivered in an Alliance framework. WorleyParsons provided all engineering disciplines required to deliver the design and was extensively involved in plant construction and commissioning.


  • Micro-tunnelling for the seawater inlet and brine discharge pipes.
  • Membrane filtration as the method for pre-treatment.
  • Split-hybrid membrane loading configurations - reduced operating pressure of the first pass reverse osmosis system.
  • Reverse osmosis racks designed from scratch - eliminating all fabrication and operational (leaking) issues.
  • Unique reverse osmosis building and piping layout - specifically developed to limit pump noise in the membrane area

Key Achievements

Awarded ‘International Desalination Plant of the Year - 2012’ by the International Desalination Association

Delivered the first large plant in the world to use membrane filtration as a method of pre-treatment
