Water & Wastewater

We have significant experience and expertise delivering engineering design and operational support services across a range of industries.

We have worked across  water, mining, oil & gas industries in the areas of management, transport & treatment of water, wastewater, and water related requirements. We offer design services for pumping, storage, pipelines, treatment, RO, hazardous area, automation, SCADA and telemetry systems.

  • Pipeline assessment
  • Water network modelling and transient analysis
  • Sludge treatment plants
  • Hazardous area compliance

GPA performed hazardous area upgrades at two major wastewater treatment plant sites: Glenelg WWTP and Bolivar WWTP. The scope of each project was to ensure that the sites were fully hazardous area compliant to the applicable standards. We provided a full turnkey upgrade that included: detailed design, procurement of materials, and contracting and management of multiple installation contractors to perform the identified upgrade works.

We have capabilities in modelling water networks across a wide range of applications including steady state and transient flow arrangements. GPA has established detailed models of hydraulic systems for design validation, optimisation and debottlenecking purposes. The modelling software allows for ongoing analysis of the effects due to expansion to, or changes in, the existing network. This includes: fouling, network isolations or water source cessation.
