Wagga Wagga Operations Wagga Wagga City Council and Tenix recently hosted a tour of the Council's main sewage treatment plant as part of the 2012 Local Government and Shires Association (LGSA) Water Management Conference in July. The Narrung Street Sewage Treatment Plant is the largest of the Council's three plants serving the rural city. Tenix operates and maintains the plant, along with two others, as part of a Design, Build and Operate contract made with the Council in December 2007. Under the performance-based contract, Tenix designed and built major upgrades to the Narrung Street and Kooringal Sewage Treatment Plants, and now operates the plants along with the Bomen Industrial Sewage Treatment Facility - a 4.5ML/day capacity SBR plant designed and built by Tenix in 2004/05. Tenix took over the operations of the Narrung Street and Kooringal plants in January 2008 in preparation for their $42 million upgrade. This involved keeping the old plants operating while constructing the new plants on the same sites. By the end of June 2010 both new plants successfully completed commissioning and their 40-day process proving periods. Matt Brill, a Wagga local, now heads up operations of the Wagga plants. Matt has been with Tenix since they took over operations of the plants in 2008. And according to Matt, operating the plants has not been without its challenges. This includes having to deal with two floods, the most recent in March this year. Says Matt, "the 1-in-40-year March flood forced the evacuation of both the Wagga CBD and the Narrung Street plant for three days. The operations team monitored and ran the plant remotely, continuing treatment throughout the flood." "Once the flood subsided it took only five days to bring all systems back online. There was only minor damage to non-critical equipment and no injuries. Our flood management plan worked well, and strong collaboration throughout the flood event resulted in the plant continuing to perform well." Chris Yeats, Tenix's General Manager for Water points out that Tenix is no stranger to having to deal with flooded treatment plants. "In 2010 flooding occurred at Narrung St which also resulted in inundation. We have also seen floods in Mackay and Bega during March of this year. The strong processes on site and the dedication of our teams gets us through these difficult situations!" said Chris. Tenix Case Study z Highlight The Wagga Wagga sewerage network services over 18,000 residential and 2,000 non-residential properties. Apart from the treatment plants, the network consists of over 530 kilometres of gravity and pressure mains and 36 pumping stations.
