industry news regular features 28 MARCH 2011 water AWTP Transforms Process Water Ovivo Australia last year completed building an advanced water treatment plant (AWTP) for Inghams Enterprises at their Murarrie Processing Plant in Brisbane. The cutting-edge design enables more than 70 per cent of all the process water to be transformed into drinking water of an internationally recognised and approved quality. The plant currently treats the equivalent of two Olympic-size swimming pools of process water per day and when it reaches its full potential, will treat close to three. The water is re-used in combination with town water to supply increasing water demands, saving 3.15 million litres of water each day by the time the plant reaches full capacity in 2011. The plant has now been running for almost a year and has been so successful that Inghams has approved the construction of a second facility in Victoria. United Utilities Now Owned by Consortium United Utilities has completed the sale of its 100 per cent owned subsidiary United Utilities Australia Pty Ltd (UUA) to a consortium led by Mitsubishi Corporation. The transaction, valued at approximately AUD$225 million, was finalised in October last year. In addition to Mitsubishi Corporation (59 per cent), the consortium comprises the Innovation Network Corporation of Japan (INCJ, 30 per cent), Manila Water Company (1 per cent) and J GC Corporation (10 per cent). United Utilities states that the consortium members have substantial investments in the water and wastewater treatment sectors globally and will contribute significantly to the expertise and experience of the UUA management team in the provision of design and construction, operation and maintenance and asset management services. UUA Managing Director Mr Roch Cheroux is replaced by Mr Francois Gouws, who steps up from his role as UUA Design and Construction Director. The company will continue to be based in South Australia. 2010 Rainfall in MDB Hits a 100-year High National Water Market Specialist, Waterfind, recently released its report on observed average rainfall within major irrigation districts in the Murray-Darling Basin. The report showed that the rainfall for the 2010 calendar year represented 163 per cent of the long-term average and created a new 110-year rainfall record. This compares to the previous high rainfall years of 1917, 1956 and 1974 within the basin of 138 per cent, 146 per cent and 158 per cent respectively. Waterfind CEO, Mr Tom Rooney, said the record rainfall year experienced within the basin coincided with record water storages, allocations and low temporary water pricing. Waterfind observed over 18 million megalitres (ML) of active storage within the basin in 2010, which exceeds the previous high of 13.9 million ML recorded in 2000. Mr Rooney said the enhanced storage position has been as a result of rainfall conditions, as well as increased carry-over rules within the southern systems, which have left water in storage from a previous irrigation season. Mr Rooney said historic odds indicate 2011 will also be a year of high rainfall within the basin, as there has only been one time in the past 110 years when average rainfall above 140 per cent has not been followed by a subsequent above-average rainfall year. This 110-year aberration was in 1906. For more information please call Waterfind on 1800 890 285 or go to: www.waterfind.com.au. WA Launches Groundwater Replenishment Trial The Western Australian Government has launched the country's first groundwater replenishment trial, which involves treating recycled water to drinking standards and recharging it underground. The Department of Health approved the trial following extensive commissioning of a purpose-built Advanced Water Recycling Plant, located north of Perth in Craigie. The plant will produce up to five million litres of recycled water each day, which is then recharged to a confined aquifer situated between 120 and 200 metres underground. The trial will determine whether recycled water could potentially help boost Perth's drinking water supplies and will also help to confirm "desktop research" indicating groundwater replenishment may be cheaper and less energy-intensive than desalination, according to WA Water Minister, Graham Jacobs. The Federal Government contributed $19.4 million to the trial through the Water Smart Australia program, with the WA Water Corporation contributing a further $31.5 million over its three- year life.
