GO specialises in the design and construction of water treatment and pumping facilities.

Areas we work in:

  • Water Treatment 
  • Media and Membrane Filtration

  • Stormwater and Wastewater Reuse Schemes
  • Pumping Stations

We engage specialist design consultants for process and structural engineering, complementing this with our in-house detailed design and drafting team. We also engage specialist suppliers and subcontractors and our construction teams in the design process, providing robust design solutions that are innovative, cost effective and easily constructible.

We have in-house construction and commissioning teams who work solely on water projects, meaning that work proceeds smoothly and efficiently throughout construction, testing and commissioning. Our modern office and excellent working conditions mean that we have low staff turnover and avoid industrial and contractual disputes, minimising costs for our clients.

GO has extensive experience working through design & constructs as well as a range of relationship contracting models. We have delivered numerous projects through Early Contractor Involvement (ECI) as well as Alliance, Target Outturn Cost, Framework Agreements and panel arrangements. A number of projects have also been delivered through successful Joint Venture arrangements.


“GO demonstrated their commitment to this strategy which was paramount to its' success both in terms of preparedness to work collaboratively, commitment to achieving the required outcomes and objectives, open and honest communications and integration with the SA water project team.”
