Metal Maintenance is a lead supplier for maintenance and plants support to Veolia Water Australia with long term contracts for maintenance, cleaning and painting.

The company maintains the plant in “hot–standby” for the Gold Coast Desalination Plant as required by the Qld Government.

“The Gold Coast Desalination Plant is a 125 ML/d (46 gigalitres per year) reverse osmosis, water desalination plant located in Bilinga, a seaside suburb of the Gold Coast, in Queensland, Australia. It supplies water to the South East Queensland region via the South East Queensland Water Grid.

The plant first supplied water to the grid in February 2009. Seqwater owns the plant and is operated by Veolia. As of Summer 2020/2021, the plant is operating at maximum production capacity.

Water supplies in southeast Queensland reached very low levels during Australia’s ‘Millennium drought’, primarily from 2003 to 2009. The region’s major water storage reached around 50% of capacity in mid-2005 and 20% in mid-2007. In response to this worsening situation, we proposed a range of water infrastructure projects to bolster supplies in southeast Queensland.

The Gold Coast City Council initially developed a plan for a 55 ML/day desalination plant during 2005., which was anticipated to cost around $260 million. However, due to worsening drought conditions, in 2006, the Queensland Government joined with the Gold Coast to expand the plan to a 133 ML/day plant that could share the output with the entire region. The Queensland Government contributed $869 million to the expanded project, which was to be developed through a 50:50 joint venture.”

“The Western Corridor Recycled Water Scheme, a recycled water project, is located in the South East region of Queensland in Australia. The scheme that WaterSecure manages is a crucial part of the SEQ Water Grid constructed by the Queensland Government in response to population growth, climate change and severe drought. The A$2.5 billion project is reported as the largest recycled water project in Australia.

The Western Corridor is the area from Brisbane’s southwest suburbs towards the city of Ipswich. For many years the corridor has experienced significant population growth with the development of the suburb of Springfield and the resultant extension of the Centenary Highway and the upgrade to the Ipswich Motorway.

The scheme involved the construction of three advanced water treatment plants constructed at Bundamba, Luggage Point and Gibson Island, which draw water from six existing wastewater treatment plants in the region to produce up to 232 megalitres of purified recycled water daily. The water is distributed via a network of pipelines measuring more than 200 kilometres in length. Construction began on the Recycled Water Project in 2006 and was completed in late 2008. A$408 million of funding was provided by the Australian Government via its Water Smart Australia Program.

In Stage 1 of the project, the scheme has provided an alternative water source for Swanbank Power Station and both Tarong Power Station and Tarong North Power Station. Supplies to Swanbank started in 2007, and supplies to Tarong and Tarong North started in June 2008.

The system can provide water to other industrial users and agricultural users and supplement drinking water supplies in Wivenhoe Dam. Testing of the pipeline to Wivenhoe Dam has been conducted, however in November 2008, Premier Anna Bligh declared that recycled water would not enter the dam unless levels drop to below 40%. As of May 2009, the three power stations are the main customers of the recycled water, consuming 112 megalitres per day.

Since coming online in August 2007, through to July 2010, the Western Corridor Recycled Water Scheme has supplied more than 37 thousand megalitres of water into the SEQ Water Grid.”

Water Treatment Plant Maintenance Projects

Winch and Trash Screens Installation at Dam

Supply, installation and commissioning of an electric chain hoist and all lifting accessories. Installation of new trash screens and guide rails and operator training on the new winch system.

Water Treatment Plants Vermin Proofing

Existing Vermin Proofing (shade cloth) and screens under the whirly birds at water treatment plants were failing and non-compliant.
In addition all the fascia and cross bracing needed replacing.

Switchboard Roof Structure at a WTP

Works included the fabrication and installation a new roof over an existing switchboard to provide weather protection during maintenance tasks for the electrical switchboard, without affecting switchboard operation.

Sulphuric Acid Skid Pipe Upgrade and Pressure Test

Part of the recommissioning works of the Luggage Point Advanced Wastewater Treatment Plant, the sulphuric acid system had been identified as high risk of failure due to the age of the plastic piping.

Protective Coatings Site Painting of GRP Tank

The original coating was degrading and would have reduced the tank life. Scaffolding was erected around the entire tank, abrade the surface to relevant standards and recoated the tank with epoxy paints.

Refurbishment of Intake Screen at a WPS

The refurbishment of these 2 intake screens will allow the plant to continue to meet the required performance to provide a reliable and long-term system for effectively collecting debris in the raw water intake tunnels.

Temporary Storage Water Tanks at a WTP

Scope of works was the supply and install three water tanks and associated piping for temporary storage while work was carried out on the roof on the main storage reservoir at the water treatment plant.

Laser Alignment of Rotating Equipment

Metal Maintenance can perform alignment checks completed to client or manufacturer specifications, regular alignment checks will reduce equipment wear and vibrations and increase equipment life.

High Pressure Pump Overhaul at GC WTP

Metal Maintenance was required to dismantle, conduct durability inspections, reports, reassemble and then the commissioning of the high-pressure pumps at the Gold Coast Desalination Plant.

Water Reservoirs Roof Gutters and Stormwater

Metal Maintenance designed and constructed roof gutters and stormwater systems for 2 water reservoirs. Also included in the scope of works was flooring replacement at the adjacent water pump station.

Wolleebee Creek Northern WTP Heat Exchanger Clean

Metal Maintenance used high pressure jet rod to descale the vent condenser at the Woleebee Creek Northern WTP. The vent condenser on the brine concentrator becomes blocked and results in reduced flows.

Gravity Thickener Refurbishment at WWTP

Metal Maintenance were contracted by Veolia Water to dismantle and refurbish the gravity thickener, this included the servicing the drive gearbox at Luggage Point Advanced Wastewater Treatment Plant.

Installation of Fluoride Hopper Shut Off Valves

Concept design of gate valves that eliminates the requirement of manual handling associated with a manually operated valve. The fluoride powder sits in the valve slide and makes them difficult to fully close.

Repair Filter Outlet Assemblies at a WTP

The filter outlet pipework assembly and isolation valve spindles at a water treatment plant required replacement. There was varying levels of corrosion and some surfaces are not coated to prevent corrosion.

Membrane Loading Installation/Replacement

Metal Maintenance recently used an innovative system and methodology to replaced over 3,400 2nd pass, and over 13,300 1st pass Reverse Osmosis Membranes at the Gold Coast Desalination Plant.

Installation of Chemical Dosing Skid Cabinets

Metal Maintenance designed, fabricated and installed custom-made safety cabinets on all of the chemical dosing skids at the Central and Relocatable Water Treatment Plants in Chinchilla.

Maintenance Shade Sails and Posts at a WTP

Scope of works included the fabrication and installation new hot dipped galvanised posts from Practical Engineering`s design, that supported the shade sail covers at a water treatment plant.

WTP Centrifuge Overhaul and Service

Metal Maintenance was contracted by Veolia Water to undertake the 6000hr Service and miscellaneous maintenance of their Andritz Centrifuge at the Luggage Point Advanced Water Treatment Plant.

New Transfer Pump Bypass at Bundamba WPS

The objective of the project was to undertake the recommended pipework changes ensuring the ongoing supply of PRW to Swanbank Power Station, as the existing pipework was not designed for long term use.

Treated Water Reservoir Vermin Proofing

Scope of works included fabrication and maintenance works associated with the vermin proofing to the treated water reservoir roofing and associated structures and fittings at a Water Treatment Plant.
