  • Austral Bricks
    Resource Recovery

    From Household Waste to Granny Flat – Providing Alternative Fuels from Waste

    In Australia, the brick industry is worth $2.8 billion to the economy and creates employment for 30,000 people nationwide in the manufacturing and installation of its product.

    In late 2012, Veolia, in collaboration with Austral Bricks, the construction materials company, set about an exciting new resource recovery project which could potentially provide a new fuel source for brick manufacturers across Australia.

    In Horsley Park, New South Wales, both Veolia and Austral Bricks have adjoining facilities: a landfill, and a brick production facility respectively.

    The methane, which is produced when waste decomposes, has been used as an alternative energy source at various Veolia facilities for many years, although never had Veolia become so involved in the end-product.

    The gas is captured and combusted, then transferred via specially designed pipes next door to Austral, which in turn, uses the gas to fire up the kiln to make bricks. The gas produced by dry-waste or the waste which is collected from construction sites and businesses right across Sydney is now being turned into a relatively cheap and very reliable new source of energy.

    The above partnership was the recipient of the Australian Business Award for Innovation.

  • Nyrstar
    Refractory Management & Chemical cleaning

    Since 2005, Veolia has been working with Nyrstar to improve the efficiency of its operations, safety management and asset management, leading to savings of $1.2 million.

    Nyrstar is an integrated mining and metals business, with market leading positions in zinc and lead. Nyrstar’s smelter in Port Pirie, South Australia, is a significant contributor to the State’s economy through the lead, zinc, silver and gold it produces and exports. In order to achieve optimal smelter performance necessary to meet critical production targets, Nyrstar required a refractory management specialist with a proven track record in safety, environmental management and asset management. 

    The strong relationship developed between Nyrstar and Veolia has delivered a world-class partnership that has set a benchmark for refractories performance through continuous improvement initiatives, smarter processes and technologies. 

    Veolia has already implemented the following improvements for the Nyrstar operation:

    • Audited and documented all refractory assets on site 
    • Established a baseline for future performance improvements
    • Introduced hydration testing for specialised mag chrome bricks used in refractory lining – to check if bricks were still usable
    • Improved the refractory lining for the short rotary furnace that has reduced operating times and the cost of production
    • Procured cost-effective and better performing refractory bricks. 

    A core component of Veolia’s refractories management capability is its approach to asset management. Veolia’s asset management model defines the most important factors involved in decision-making with respect to operational and managerial levels. The approach also involves deciding the remaining age value for critical repair items such as refractory lining of a smelter.

  • Australian Government - Department of Defence
    Department of Defence
    Commercial Waste

    In October 2014, Veolia signed a six-year agreement with the Commonwealth of Australia, represented by the Department of Defence for a total waste management solution.

    As a critical function of the Australian Government, the Department of Defence is responsible for defending Australia against armed attack. The Defence portfolio consists of a number of component organisations that together are responsible for supporting the defence of Australia and its national interests. Defence organisations include the Royal Australian Navy, the Army and the Royal Australian Air Force. In October 2014, Veolia signed a six-year agreement with the Commonwealth of Australia, represented by the Department of Defence for a total waste management solution.

    The contract awarded to Veolia will directly support the Department of Defence’s strategic environmental objectives including sustainable environmental management, resource efficiency and pollution prevention.

    During mobilisation of this contract 8,000 waste receptacles were issued to 377 Department of Defence sites. To service the supplied receptacles 11 dedicated waste collection vehicles were added to Veolia’s existing fleet. In addition to 10,000's of tonnes of waste, the Department of Defence can now ensure the sustainable disposal of more than 40,000 used vehicle tyres each year from their expansive fleet of more than 6,000 light, medium and heavy vehicles.

    Veolia is committed to working closely with local communities who are located near project locations and facilities to deliver regional employment. To do enable this Veolia will be actively engaged with local suppliers, potential employees and contractors. Importantly, this project will provide ongoing support for Veolia’s Reconciliation Action Plan which is aiming towards an Indigenous Australian employment target of 2.5% within their workforce over the next five years.

    With its vast operational presence across Australia, including many remote and regional areas, coupled with a focus on sustainable waste management, Veolia is helping the Department of Defence minimise its waste-related environmental impact through proven management processes and innovative waste treatment technologies.

  • Origin Energy
    Industrial Services

    As one of Australia’s leading energy companies, Origin Energy must undertake regular shutdown and maintenance of its gas plants to keep them in top working order. They needed an industrial service provider who could deliver large-scale onshore and offshore shutdown projects, while minimising maintenance downtime.

    Since 2009, Veolia and its alliance partner Dialog (a specialist in catalyst handling) have successfully delivered multiple shutdowns to Origin Energy’s Victorian assets: Otway Gas Plant and BassGas at Lang Lang.

    With our environmental focus, local expertise, experience and capabilities, and best-practice project planning and management in partnership with Dialog, we have completed all shutdown operations without safety or environmental incident and to tight timeframes. Crucially, we have helped minimise the disruption and downtime to Origin’s gas extraction and processing operations.

    2016 slug catcher cleaning
    During the 2016 shutdown at the Otway Gas Plant, Origin engaged Veolia to clean its slug catchers – the most dangerous, and most contaminated, part of the plant. Adding to the challenge, Veolia had only a three-week shutdown period to develop and deliver the cleaning operation before the plant was brought back online.

    Our industrial services team in Victoria consulted with local technicians and international experts to develop a tailor-made solution. Using a combination of chemical cleaning and other specialised equipment, we successfully emptied and cleaned the slug catchers well within the shutdown timeframe. And, with the slug catchers performing to their full capacity, Origin can now allow more time between shutdowns, meaning less downtime for the plant.

    QGC is a leading coal seam gas explorer and producer focused on establishing the world's first project to convert coal seam gas into liquefied natural gas - Queensland Curtis LNG (QCLNG). 

    QGC is wholly owned by BG Group, a leading player in the global energy market. Veolia works with QGC to provide a number of vital services: vegetation management; total waste management; and water treatment plant operations.

    Vegetation Management

    In December 2015, Veolia was awarded a contract to provide QGC with vegetation management services covering all their upstream assets. Veolia was chosen for its innovative approach to vegetation management that delivers cost efficiencies while meeting strict environmental compliance requirements.

    Due to the large area being serviced across the Surat Basin, Veolia employed a project management model where all manual field work was subcontracted. Subcontractors were engaged under commercial terms that ensured the seamless integration and compliance with the head contract conditions.

    The subcontractor model uses Veolia systems where live field data updates are available to Vegetation Management Advisors to monitor and regularly audit ongoing operations ensuring vegetation objectives and compliance are met.

    Total Waste Management

    QGC required a consolidated waste management solution for its numerous operations in the Surat Basin stretching from the south-west of Chinchilla through to the north-west of Wandoan.

    Since 2015, Veolia has provided QGC with a total waste management solution with an approach based on the following key characteristics:

    • Structured resource recovery program that focuses on each individual segregating waste at the disposal source. The program also includes the identification of reuse, recovery, recycling, treatment and disposal options locally and throughout QLD.
    • Standardised operational model applied across QGC’s entire upstream operations and service area.
    • Specialised regulated and liquid waste collection vehicles to support well engineering operations, and multi-skilled labour.
    • ​Tailored waste management services for the various operational requirements of both QGC’s fixed facility assets and well-engineering rigs and drill camps.
    • ​Veolia’s approach that takes into account the desirable steps of the waste management hierarchy for avoiding, reusing, recycling and recovering waste. The end goal of the process is to minimise waste going to landfill

    Water Treatment

    In April 2013, Veolia was awarded a 20-year contract to operate and maintain QGC’s three water treatment plants which treat groundwater produced alongside natural gas. Veolia was chosen for its unique expertise in managing the complete production water treatment cycle in the complex field of unconventional oil and gas.

    Utilising a highly skilled team of 55 employees including electricians, instrument technicians, plant operators and water engineers, Veolia operates and maintains the water treatment plants ultrafiltration, ion exchange, reverse osmosis and brine concentration equipment in addition to pump stations and electrical substations.

    The gas field operated by QGC spans 4,500 square kilometres. Plans call for drilling of 6,000 wells by 2030 and Veolia will treat the production water of each new well brought on stream. In all, close to 200,000 cubic metres will be treated per day (the volume of 80 Olympic swimming Pools) and a very high-quality end product will be guaranteed on a long-term basis. The production water, which is pumped up from the wells at the same time as the methane, has high salt content and must undergo complex treatment before it can be reused in industry or agriculture.

      Coliban Water
      Water Management

      In 1999, Coliban Water engaged Veolia to undertake the AQUA 2000 Project, which was a 25-year contract to build, own, operate and transfer water treatment plants and supporting infrastructure for Bendigo, Castlemaine and Kyneton. In 2010, Coliban Water and Central Highlands Water again contracted Veolia to operate and maintain the entire Goldfields Superpipe 160km pipeline. 

      Coliban Water is one of the larger Victorian Regional urban water corporations responsible for 35 reservoirs and water storage basins across North-Central Victoria.

      In the late 1990s, Australia began experiencing severe drought conditions that stretched on for well over a decade. During this period, Coliban Water required a partner who could deliver advanced water treatment infrastructure to guarantee water supplies to the towns of Bendigo, Castlemaine and Kyneton. 

      Since completing the construction, Veolia has continued to surpass expectations as the primary operations and maintenance contractor for the plants and supporting infrastructure. The main plant in Bendigo has a capacity of 126 megalitres per day and features submerged microfiltration technology while the Kyneton plant (eight megalitres per day) and Castlemaine plant (18 megalitres per day) use conventional microfiltration. 

      Veolia has introduced upgrades & initiatives including:

      Hunter Water
      Water Management

      Hunter Water is a State Owned Corporation (SOC) providing drinking water, wastewater, recycled water and some stormwater services to a population approaching 575,000 people across the Lower Hunter.

      In 2014, Hunter Water was acutely aware of the mining industry downturn which caused a spike in the number of families in the Hunter to experience financial hardship. With this in mind, Hunter Water required an outsourced asset management solution that would help ease this pressure and keep water bills low while ensuring the continued delivery of safe and reliable water and wastewater services. 

      In June 2014, Veolia was awarded a contract to operate and maintain Hunter Water's 25 treatment plants. The $279 million contract is the largest ever awarded by Hunter Water and comes after a 12-month tender process overseen by independent procurement specialists to ensure the integrity of the process. This contract has seen Veolia create 65 positions; further adding to an existing workforce of 270 Veolia employees across the Hunter region. Under the eight-year contract, Veolia is operating and maintaining the plants which supply potable water and wastewater treatment services to over half a million people in six local government areas.

      The area of operation covers 5,366km with a population close to 575,000 in the local government areas of Cessnock, Lake Macquarie, Maitland, Newcastle, Port Stephens, Dungog and small parts of Singleton.

      Desalination Plant

      Sydney is hugely reliant on dams and rainfall to provide its drinking water. With Sydney’s growing population and uncertain rainfall predictions due to climate change, the NSW State Government recognised a need for a new, non-rainfall dependent source of water to secure the city’s water supplies for the future.

      In June 2010, Veolia worked with John Holland in a joint venture to design and build Sydney’s Desalination Plant on behalf of Sydney Water. The plant is located on a 45 hectare site at Kurnell and includes a 15 hectare environmental conservation area. Essentially, seawater is treated using reverse osmosis which pushes seawater through membranes where salt and any other impurities are removed, producing freshwater.

      Veolia now operates and maintains the plant and intake/outlet structures under a 20 year contract, while ownership of the plant lies with Ontario Teacher’s Pension Plan (OTPP) and Hastings Fund Management (HFM).

      Sewerage Scheme

      The regional townships of Gerringong and Gerroa located on the NSW south coast required a reticulated sewerage system that would allow for water reuse. In 2002 Veolia pioneered an efficient treatment system on behalf of Sydney Water, designing and building a sewerage scheme – the first of its kind by the private sector within the Gerringong region.

      The scope of the project consists of a treatment plant, 50 kilometres of pipelines and 12 pumping stations. The scheme is designed to reuse 80% or more of the treated effluent for irrigation at a local dairy farm. There are also occasional discharges into adjacent sand dunes and into a nearby natural wetland in extreme wet weather conditions. The scheme’s 2.2ML/d capacity sewage treatment plant services a population of 8,000 and is located on Baileys Island, south of Gerroa and adjacent to the Crooked River.


      Water Treatment Plants

      In the early 1990s, Sydney Water needed to improve the quality of Sydney’s drinking water to meet the more stringent standards for drinking water introduced by the National Health and Medical Research Council. As a result, Veolia began a long-term partnership with Sydney Water in 1994 to build and operate the Illawarra and Woronora (Wyuna) Water Treatment Plants. The design, construction and commissioning components of the project cost approximately $AUD182 million.

      The Woronora Water Treatment Plant was constructed at Woronora Dam to filter water supplied from the Woronora Reservoir. This plant was designed with a maximum capacity of 160 megalitres per day; however the daily production rate varies due to a range of external factors affecting water demand. The Illawarra Water Treatment Plant was constructed to treat water from the Avon Dam, and produces up to 210 megalitres per day. A hydro-electric facility enables this plant to be entirely self-sufficient, exporting renewable energy back to the grid.

      Rosehill Recycled Water Scheme

      The NSW Government has a goal to increase the amount of water recycled in Sydney to 70 billion litres a year by 2015. The Rosehill Recycled Water Scheme is one water recycling project under the NSW Government's Metropolitan Water Plan that supports this commitment by encouraging industrial and irrigation customers to use recycled water instead of drinking water.

      AquaNet Sydney (part of the Jemena Ltd group) together with Veolia designed, built, own and operate the Rosehill Recycled Water Scheme. This project includes the Fairfield Recycled Water Plant with a capacity of 20 megalitres per day, two pump stations and three reservoirs connected by 20 kilometres of pipeline. Veolia was responsible for designing, building, financing the water recycling plant and is now operating and maintaining it under a long term contract.

      The plant produces 4.3 billion litres a year of highly treated recycled water for major industrial and commercial customers in Rosehill and Smithfield, reducing demands on drinking water supplies. The plant is specifically designed for future demand by being capable of producing an extra three billion litres of recycled water per year if required at a later date. Construction of the pilot plant commenced in early 2009, and the scheme was completed in mid-2011. This is Australia’s first private scheme for high grade recycled water.

    • Central Highlands Water
      Water Management

      Veolia has been involved in the design, build, operation and management of a variety of large scale water-related facilities in the Central Highlands region of Victoria. These projects have been carried out in partnership with Central Highlands Water, a state-owned water business and is focused on providing high-quality drinking water, sewerage, trade waste and recycled water around the city of Ballarat and nearby towns.

      Water Treatment Plants

      In the Central Highlands region of Victoria, Veolia is currently responsible for the operation and maintainance of seven water treatment plants, which are managed by the Victorian Veolia team.

      Avoca - The Avoca Water Treatment Plant consists of two streams which operate depending on the raw water source: from two surface water reservoirs; or alternatively, from a ground water source. In 2009, the plant was upgraded with the installation of Reverse-Osmosis (RO) membranes in order to enable treatment of underground brackish water. In 2012, Veolia took over operational control of the Avoca Water Treatment Plant.

      Veolia understands the importance of continuous improvement, and have put in various measures at the Avoca Plant related to reducing occupational health and safety risks. Veolia is also looking to trial new systems such as new bag filters to reduce the backwash water volumes found in the sand filter. This will allow the water to be recycled to the head of the plant or pumped to the Lead Reservoir.

      Ballarat - In April 1999, Central Highlands Water awarded Veolia a 25 year contract to operate and maintain two 65 megalitres per day water treatment plants, a pumping station and raw water pumping facilities. These provide water to the city of Ballarat and surrounding townships. The contract also covers facilities in the greater Ballarat region including the Ballarat North Water Reclamation Plant, two Dissolved Air Flotation Filtration plants and two ion exchange groundwater softening plants.
      With dedicated staff and a robust business management system, the plants continue to perform at optimal levels, producing 130 megalitres of water per day and serving a population of 100,000.

      Throughout the contract period optimal performance outcomes have been achieved through Veolia’s unique asset management approach. This consists of a complete and regular assessment of all assets that allows for accurate asset replacement planning and budgeting, enabling transparency and operational efficiency for Central Highlands water treatment assets.

      Water Reclamation Plant 

      In 2005, Central Highlands Water issued a brief for its Ballarat North Water Reclamation Project, which had the objective of increasing overall water availability to the region through an alternative and additional water supply.

      This contract commenced in 2006 and initially involved Veolia taking over the operations of an existing wastewater treatment plant. In 2007, construction commenced on the new Ballarat North Water Reclamation Plant which Veolia now operates under a 15 year contract.

      This plant was completed in 2008 and is capable of treating 8.4 megalitres of wastewater per day, while improving the quality of treated water discharged to the environment. It also includes a thermal sludge dryer which produces biosolids to a standard suitable for beneficial land-based reuse, such as fertiliser.

    • SEQWater
      Water Management

      In 2006, south-east Queensland was experiencing its worst water shortage in over 100 years, with over 60% of the area in drought.

      The combination of climate change impacts, well below average rainfall for the previous six years, and significant population growth, meant that the Queensland Government was looking for a reliable, long term water supply.

      The Government announced the South East Queensland Regional Water Strategy which included the A$9 billion Water Grid. This grid enables water to be transported from surplus areas to those in shortage. The Gold Coast Desalination Plant is a climate-independent source of water that ensures South East Queensland’s water security in time of drought and extreme weather.

      Veolia’s solution

      Veolia, in an alliance with John Holland, SKM and Cardno, was awarded the contract in November 2006 to deliver this plant. The alliance designed, constructed and commissioned the plant to achieve first water by November 2008 and commenced supply on 26 February 2009. Veolia now has sole responsibility for operating and maintaining the plant for a 10 year term, with the option for a further five years.

      The plant is able to provide an average of 125 megalitres per day of water to the network which is enough drinking water for more than 650,000 people.

      Throughout 2010, heavy rainfall filled the region’s dams to full capacity. In January 2011 significant flooding occurred in south-east Queensland. During this time the South East Queensland (SEQ) Water Grid (which includes both the Western Corridor Recycled Water Scheme and the Gold Coast Desalination Plant both operated by Veolia Water) was able to supply to more than 95 per cent of the affected region without interruption or degradation to quality, according to a study undertaken by the SEQ Water Grid Manager.

      In mid-2011, the Queensland Government placed the plant into hot standby mode – with capability to return to full production within 72 hours if needed to maintain water supply or quality across the Water Grid. The plant will return to full production if the region’s combined dam capacity drops to 60 per cent.

      • Mobile PFAS treatment
        As innovative approach to treating PFAS contaminated water

        The client required a solution to treat a large body of PFAS contaminated water which had the potential to overflow into other local water catchments for 9 months of the year due to high rainfall. A solution was needed to mitigate risk of the onsite dam overflowing, potentially causing environmental, financial and reputational impact for the client.  A mobile technical solution was needed to effectively treat large amounts of PFAS affected water, but also and have the capability to re-use that water to improve flora and fauna in the local area.
