Derek Gee installations installed over 17 kilometres of GRP pipework onsite at the Binningup Stage 2 Desalination Plant, located near Bunbury, Western Australia, commencing work on February 7th, 2012 and finishing in June 2013.

Employing up to 70 people onsite, we were responsible for all the GRP pipe installation, and joint laminations. Including the complete hydro/pneumatic testing of all pipework and tanks, membrane loading, strainer spooling modifications for stage 1 and 2, miscellaneous mechanical works and site commissioning.

Over 2800 joints were completed with no remedial work, with over 100,000 man hours with no lost time injuries, as a result of the strong site safety discipline applied, and procedures adopted on site.

In 2018, DGI provided a large crew of Trades Assistants and Fitters to Evoqua Water Technologies to load 960 x L20N UF membranes modules on the Southern Seawater Desalination site, along with providing crews for site shut downs.

Project Background

The plant was designed to be constructed in two stages – both capable of producing 50 gigalitres (GL) of water a year.

The second stage doubled the plant's capacity to 100 GL. With the output of the Perth Seawater Desalination Plant, almost half of Perth’s water needs are supplied by desalination.

Major upgrades were made to the southern section of the Integrated Water Supply Scheme to deliver the water into the system and on to customers. This included additional pipelines and construction of a new pumping station.
