Metal Maintenance is a lead supplier for maintenance and plant 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. It is owned by Seqwater and operated by Veolia. As of Summer, 2020/2021, the plant is operating at maximum production capacity.

Water supplies in south east Queensland reached very low levels during Australia’s ‘Millennium drought’, primarily from 2003 to 2009. The region’s major water storages reached around 50% of capacity in mid-2005 and 20% in mid-2007. In response to this worsening situation a range of water infrastructure projects were proposed to bolster supplies in south east 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. 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 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 is managed by WaterSecure is a key 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 south west 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 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 has the capacity to provide water to other industrial users, agricultural users and to 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 will 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.”
