Seacliff Desalination Facility

Adelaide, South Australia

Gilkes were selected as the preferred supplier for the mini-hydro equipment within the Seacliff facility as part of SA Water’s North South Interconnection System Project (NSISP). The Project was understood from the very beginning to be challenging, both from a technical and schedule point of view. The Gilkes scope of supply included the design and manufacture of the mechanical and electrical equipment, operating and maintenance documentation, installation supervision and commissioning, including integration into the existing network.

The challenging technical requirements of the project were managed directly with the Customer, with there also being numerous requirements specific to the customer and Australia. The water hydraulic requirements necessitated a relatively high speed machine running at a relatively high pressure for this type of Francis turbine, and also required a large flywheel. The pressurised downstream pipework fed directly in to the consumer network of South Adelaide. The small facility was positioned within a residential suburb of Adelaide, therefore requiring a compact design with strict noise targets.

The turbine was designed, built and pressure tested at our factory in the UK before being airfreighted to site in Adelaide. The technicians who assembled the turbine at our factory also supervised the safe and successful installation of the Gilkes equipment in Australia.
