Water & Wastewater

GPA have significant experience and expertise delivering engineering design and operational support services across the Water and Wastewater industry.

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

GPA have capabilities in modelling water networks across a wide range of applications including steady state and transient flow arrangements, with established detailed models of hydraulic systems for design validation, optimisation and debottlenecking purposes.

Water engineering services also extend to GPA’s specialist functional safety, risk assessment and hazardous area compliance offerings.

Extensive water engineering experience resulted in GPA performing hazardous area upgrades at two major wastewater treatment plant sites: Glenelg WWTP and Bolivar WWTP. GPA ensured each site was hazardous area compliant to the applicable standards by providing full turnkey upgrades. GPA was responsible for detailed design, procurement of materials, and contracting and management of multiple installation contractors to perform the identified upgrade works.

GPA’s water networks modelling capabilities reach across a wide range of applications including steady state and transient flow arrangements. We also have established detailed models of hydraulic systems for design validation, optimisation and debottlenecking purposes. Modelling applications allow for ongoing water engineering analysis of the network, including fouling, network isolations or water source cessation.
