Hedland Water Supply improvements

Water Corporation engaged GO for the design and construction of the Hedland South Fluoridation Plant and Water Supply Upgrade involving 4 separable packages in Brownfields sites. Work included a Fluorosilicic Acid (FSA) storage and dosing facility in a prefabricated modular building, switchboards, flowmeters, gate valves, dosing and sampling lines, pitometer tapping points and electrical and communications conduits. GO constructed concrete aprons and slabs, a waste holding tank, pipework, a valve pit, a soak well, infiltration bed and undertook gate modifications. The project also included roadworks, security fencing, concrete footpaths and gravel to the surrounds of buildings. The GO design included modifications minimising impact to the switchboard operators and ensuring ongoing water supplies throughout.

Hope Valley EL170 Tank enabling works

GO isolated the 136ML Hope Valley EL170 tank and replaced the roof while maintaining supply. This was achieved by installing a new sleeve discharge valve in a valve chamber next to the existing sleeve discharge valve. GO identified a number of construction and operational risks associated with locating the valve underground and proposed an innovative solution to bring the valve above ground inside a soundproof building. This solution minimised the cost of excavating rock and provided a safe working environment for operators. The project included tie-ins to the existing buried MSCL pipework and the upgrade of an existing Hydraulically Operated Control Valve (HOCV) station, replacing existing pipework, pressure control valves and electrical and control systems.

Geraldton water scheme flow monitoring

With different requirements at 11 sites, GO was selected to design, supply, install, and construct works across the Geraldton Water Scheme. The shutdown work, which affected 10,000 customers, was completed four weeks ahead of schedule and included design, supply and install of flowmeters, pressure transmitters, pipe stools, instrumentation and telemetry cubicles. GO also undertook excavation, backfill, asbestos handling, restoration and reinstatement works assisting the early completion of the project.

Sundrop Farms

Located at Port Augusta in South Australia, Sundrop Farms uses technology that integrates solar power, electricity generation, freshwater production and hydroponics to produce high-quality fresh food. Their innovative system turns seawater and sunlight into energy and water.

During construction of the facility Guidera O’Connor was engaged to design and build pump stations and GRP pipe lines to transport the seawater to the site and move water around the site. The GO team also constructed the desalination, pumping and piping systems throughout the plant.

Skye network upgrade

The objective of this project was to provide approximately 150 properties in the Skye area with a potable water supply from the SA Water network.  A number of changes to the existing network were required including new pipes, isolation valves and pressure reducing valves. GO completed Early Contractor Involvement services followed by a design and construct contract that included Potable water rising mains, 2 pump stations, 150 customer connections to the rising main and decommissioning of redundant valves and pipework. The work required pipe laying along quiet residential streets and the local traffic flow was not interrupted, meeting all of councils' requirements and the project schedule.

“It was a very challenging exercise to meet the Council's expectations and requirements. The credit goes to whole team for managing it so well… It is very satisfying to be aware of the fact that we have a very satisfied customer.”

SA Water safe access and tank roof replacement programs

GO delivered a range of safe access and tank roof replacement programs throughout regional South Australia. Work across 20 sites typically included the removal of existing structures, concrete repair and provision of new access stairways, access hatches guardrails, roof beams and roof sheeting. GO has developed innovative methods of installing access hatches and beams without the need to drain the tanks and in some cases without needing to enter the tanks. These processes have reduced safety risk and avoided the cost, time impact and environmental harm associated with draining tanks.

“Communications between SA Water and your PM and site Supervisor was exceptional. Your team completed the work 3 weeks earlier than planned after a request from the local SA Water Operations that the tank be ready for service by the September school holidays. GO’s team worked additional hours to ensure that the updated milestone request was delivered. Engineering expertise was great with engineering options provided.”
