On 1 July 2011 Allwater commenced a 10 year services alliance contract with SA Water to operate and maintain metropolitan Adelaide’s water, wastewater and recycled water systems.

SA Water chose an alliance model contract to allow it and its alliance partner to work more flexibly together in the delivery of water services to SA Water’s metropolitan customers.

As part of the contract scope, Allwater’s 350 employees provide front line services to operate and maintain metropolitan Adelaide’s water supply system which includes 9,000 kilometres of water mains as well as six treatment plants. The contract also covers the operation and maintenance of 7,200 kilometres of sewer mains and six wastewater treatment plants along with various recycled water schemes and minor capital works delivery.

Each year Allwater anticipates delivering around 130,000 ML of water to metropolitan Adelaide customers, treating 88,000 ML of wastewater and recycling approximately 26 ML of recycled water mainly for irrigation purposes.

All assets remain in Government ownership and all customer billing continues to be managed by SA Water.

The Alliance Partners

SA Water > South Australian Government owned water utility that has been managing the State’s water and wastewater services for almost 160 years. Currently employs more than 1,500 staff across the State.

Transfield Services > Australian based provider of operations, maintenance, and asset and project management services, with over 50 years experience. It is an award winning leader in alliance contracting and has 1,200 employees in South Australia.

Suez Environnement > Paris based global leader in the environmental field for over 150 years. It has water utility experience in the management of public utility infrastructure in Europe and the USA, supplying around 76 million people with water. It has 62,000 employees worldwide.

Degrémont > Subsidiary of Suez Environnement and has been designing, building and operating water and wastewater treatment plants for more than 70 years, with more than 10,000 sites worldwide equipped with Degrémont technology.

About AllwaterAllwater is a joint venture between Transfield Services, Suez Environnement and Degrémont; with each company bringing a wide range of water expertise to the partnership.

For us, the challenges involve not just transporting, filtering and disinfecting the water from our rivers, reservoirs and other supplies, but in managing these vital resources in an environmentally sustainable manner.

Metropolitan Adelaide has traditionally been depended upon the River Murray to supplement its water supply from its local catchments. More recently water security has been enhanced with the construction of a large desalination plant at Lonsdale and the interconnection of the southern and northern water networks.

The metropolitan Adelaide system managed by Allwater includes more than 120 large storage tanks, 59 pumping stations, and six treatment plants. The nine metropolitan reservoirs and major trunk mains from the River Murray are managed by SA Water.

In the 1970’s – 1990’s a series of major conventional water filtration plants were constructed to ensure the Adelaide’s water supply met high water quality standards. These plants and their design capacities are:

> Hope Valley Water Treatment Plant : 273 ML/d

> Anstey Hill Water Treatment Plant : 313 ML/d

> Barossa Water Treatment Plant : 160 ML/d

> Little Para Water Treatment Plant : 160 ML/d

> Happy Valley Water Treatment Plant : 850 ML/d

> Myponga Water Treatment Plant : 50 ML/d

The Adelaide Desalination Plant (300 ML/d) is managed under a separate contract, with only the transfer pumping system being part of Allwater’s scope of works.

Water SupplyFaced with a widely dispersed population in one of the driest inhabited places on earth, the State of South Australia has had to develop significant expertise in the management and transportation of water over vast distances.

South Australia led the nation in installing wastewater treatment systems and was the first Australian capital to achieve secondary treatment of all wastewater.

The metropolitan wastewater system includes more than 300 wastewater pumping stations and over 40 odour control fan stations.

Adelaide’s wastewater comprises a mixture of domestic sewage (waste from household toilets, sinks, showers and washing machines), industrial effluent, occasional run-off of surface water and groundwater which has infiltrated into the sewers.

The six wastewater treatment plants in the Adelaide metropolitan area and their design capacities are;

> Bolivar Wastewater Treatment Plant : 164 ML/d

> Bolivar High Salinity Wastewater Treatment Plant : 32 ML/d

> Glenelg Wastewater Treatment Plant : 60 ML/d

> Christies Beach Wastewater Treatment Plant : 45 ML/d

> Aldinga Wastewater Treatment Plant : 2 ML/d

> Myponga Wastewater Treatment Plant : 0.05 ML/d

These plants have all been upgraded in recent years to meet growing demand and higher environmental standards.

Wastewater Wastewater treatment is a complex operation and vital to protect public health, the environment and our quality of life.

Recycled WaterRecycled water schemes play a significant role in reducing the amount of nutrients discharged to sea and minimise the use of drinking water for non-potable applications like open space irrigation.

Allwater operate and maintain multiple wastewater and stormwater recycling plants and schemes.

> Bolivar Dissolved Air Flotation Filtration (DAFF) Plant: the largest recycling plant Allwater operate and maintain and provides tertiary treatment through filters and disinfects wastewater from ponds allowing it to be used for direct irrigation of crops.

> Mawson Lakes: ‘Class A’ treated wastewater from the Bolivar Plant is mixed with harvested stormwater and used for garden watering and toilet flushing.

> Virginia Pipeline: approximately 200 market gardens take ‘Class A’ tertiary treated wastewater from the Bolivar DAFF for distribution through the privately owned Virginia pipeline for direct irrigation of crops.

> Glenelg Recycled Water Scheme: delivers recycled water for Adelaide parkland irrigation, reducing discharge of treated wastewater to the sea.

> Southern Urban Reuse Project (SURP): supplies greenfield southern suburbs with recycled water from the Christies Beach and Aldinga Wastewater Treatment Plants via a dual pipe network.

> Aldinga: supplies treated wastewater for a large vineyard.

> Willunga Basin: the Christies Beach Wastewater Treatment Plant supplies more than 2,000 ML of treated wastewater for irrigation of vineyards and parks.

> Lochiel Park: a 100 allotment residential development utilises stormwater (wetland and ASR scheme) as an alternative water supply for non-potable uses.

> Adelaide Airport: project to harvest and deliver stormwater for irrigation to replace potable water used in and around the airport.

> Barker Inlet: $8.15 million project to harvest and deliver stormwater for use by industrial, commercial and irrigation customers in the Regency Park area.
