The SA Water Pumps projects involved the replacement of eight water pump station substations at various locations across South Australia. These substations are essential to provide electricity supply to SA Water pumping stations, which enable water to be supplied from the River Murray to Adelaide and surrounding areas and Whyalla and its northern towns.
132/3.3 kV substations are located in the Riverland and mid-north regions of the SA transmission network. These four substations are essential to provide electricity supply to SA Water pumping stations, which enable water to be supplied from the River Murray to.
132/3.3 kV substations are located in the eastern hills region of the SA transmission network. Project Summary
The design and construction of the substations included: site drainage, foundations, transformer oil containment, fire consequence, lightning protection, insulation co-ordination, a very complex earthing study due to pipeline influences, secondary systems integration with SA Water and remote end substations, control buildings and overhead line cut-ins.
We constructed new substation benches, foundations, high voltage plant and control systems within and adjacent to live assets while maintaining availability of critical electrical and water infrastructure for the state.
We conducted outage works to bring new substation equipment into service with minimal disruption to consumers. Upgrade work at the remote end substations. Installation of new overhead line structures and completed alterations to existing overhead line structures.
We replaced and upgraded protection and metering systems.
The fully equipped control buildings were subject to off-site factory testing to ensure they met IEC61850 standards.
We conducted the on-site commissioning of plant, energisation of the equipment and loading of the new transformers with SA Water pump loads.
