We have the highest safety standards and decisions are made promptly with a minimum of fuss.

Narambeen pump Stations

The MS Extension supplies the town of Narembeen and surrounding farmlands with drinking water from the Goldfields and Agricultural Water Supply. This project involved the construction of new pipelines and 2 new potable water booster pump stations, including all electrical and telecommunication works for three sites. GO performed the upgrade and refurbishment of the pump stations including the Belka booster pump station, the West Narembeen booster pump station, the replacement of discharge pipework and valves, electromagnetic flowmeters, switchboards at Belka PS, West Narembeen PS and Wadderin Tank and the electrical and control systems. GO identified design faults prior to construction and incorporated safe construction methodologies during the works.

Merbein irrigation pump station upgrade

This contract formed part of the Sunraysia Modernisation Project, which received funding from the Federal Government through the Water for the Future program. GO was contracted to design and construct the upgrade to the main irrigation pump station at Merbein while maintaining water supply during construction. A building refurbishment included concrete and steel work repairs, painting, air conditioning and insulation repairs. GO removed and replaced access platforms, ladders, stairs and handrails to provide safe and convenient access for operation and maintenance, with significant modifications also made to existing plinths. New pumps, motors and variable speed drives were installed, a temperature controlled office complete with ClearSCADA workstation, new pipework, valving and instrumentation, motor control and power supply switchboards and other electrical work.

Clapham & Wattle Park Pump Stations

These two pump stations form part of SA Waters' North South Interconnector System Project (NSISP) that transfers water from the Adelaide Desalination Plant to the northern suburbs. Both were constructed in residential areas on congested sites where multiple contractors were working. The projects involved excavation and detailed earthworks, stormwater detention systems, MSCL Pipe work and valve installations on the pump station site, soundproof Pump Station buildings and architectural treatments, pavements, stonework, landscaping, irrigation and storm water infrastructure, high pressure pumps, pipework and valving, ventilation and air conditioning, instrumentation and systems. Construction required close consultation with network operators during tie-ins and with local residents throughout the project to minimise concern surrounding the noise and traffic impact from construction work. The pump stations were completed safely and ahead of schedule allowing water to be accepted from the new desalination plan.

Bolivar WWTP main pump station upgrade

The Bolivar Main Pump Station was constructed in 1964 and houses the Adelaide and Salisbury pumps, which pump 60% of Adelaide's wastewater into the Bolivar WWTP. The project was delivered via Early Contractor Involvement followed by a lump sum contract for the detailed design and construction work. The scope included refurbishment of a 50-year-old building, replacement of all pumps, pipework and valves, as well as the replacement of all electrical, control and SCADA systems. During the ECI process GO proposed an alternative pump and pipework layout that avoided the need for existing structural floors to be removed. This meant that the risk to the structural integrity of the building was removed, safety risk was reduced and SA Water saved $1.5 million. GO built a new electrical and control system independent of the existing one, allowing the old system to remain operational so that wastewater flows were not interrupted during the work.

“The alliance/relationship style contracts of which Guidera O'Connor have been a part, have resulted in successful projects delivered for SA Water. They have allowed designs to be modified to suit stakeholders, kept costs to a minimum and contributed to the development of a large pool of ECI experience in the South Australian Water Industry.”

Ravenswood pump station

This pump station was built to ensure effective and efficient distribution of water from WA's Southern Seawater Desalination Plant at Binningup to the Perth metropolitan water storages. It included separate pumping systems for the Tamworth and Dandalup regions. GO completed the detailed design, construction, testing and commissioning of all mechanical and electrical works which included 3 x 3400kW and 3 x 1600kW Pump Sets and associated high pressure pipework, valves, cooling water and electrical systems. The Water Corporation subsequently decided to expand the capacity of the pump station to cater for increased flows from the desalination plant and directly engaged GO to undertake the upgrade work. This involved the replacement of pumps, pipe manifolds, valves, motors, transformers and VSDs for four of the existing pump sets. All work was safely completed within the designated shutdown periods.
