28 AWA News WAter APRIL 2015 VICTORIA YOUNG WATER PROFESSIONALS REGIONAL CONFERENCE The AWA YWP 2015 Regional Conference was hosted on the western Victorian coast, and Warrnambool turned on some fantastic weather. The theme of the event was ‘Saltwater Thinking: From Turf to Surf’ and was supported by GHD, Wannon Water and Veolia. It attracted a large and enthusiastic group of water professionals from across the state and the world, including two delegates from France, who timed their visit especially to coincide with the event. On the Friday afternoon, over 50 delegates attended the seminar, with engaging presentations exploring the innovative projects occurring within the region. To kick off the conference, Wannon Water MD Grant Green provided an overview of Wannon Water and his history in the water industry, casting back to his Board of Works days in Melbourne. It was fascinating to hear how the Glenelg Hopkins Catchment Management Authority (GHCMA) has developed and progressed the Judas Carp Management Program in the Glenelg River, around 150km north-east of Warrnambool. Stephen Ryan, GHCMA Waterways Planner, wowed the crowd with his video snippets of the project – in particular the electro carp fishing and fish ‘surgeries’ required to implant the more than 130 tags in carp to track and identify hotspots along the creek. Wannon Water services a number of industries across western Victoria that generate high salinity wastewater brine streams that can be difficult to manage, particularly at inland locations. David Gutteridge, a Principal Process Engineer at GHD, spoke about the Warrnambool Brine Receival Facility, a dedicated facility for collection of the high-salinity wastewater brine streams. David highlighted the challenges of finding a suitable location close to existing infrastructure, resulting in development on a former landfill site. Upstream of this facility, industry treats the waste prior to discharge at the Warrnambool Brine Receival Facility. Leno Cavarra of Veolia Water discussed the treatment system at the new mineral separation plant at the Iluka mine in Hamilton, treating the waste brine stream before sending concentrated and reduced volumes entering the Wannon system. To close the day Peter Wilson, Branch Manager of Asset Planning at Wannon Water, took us through the innovative roofwater harvesting project, from concept to operation. The scheme now harvests water from 254 homes to augment the Warrnambool water supply, saving 37 million litres of water each year. The concept is believed to be the first of its kind in Australia and utilises the simplest of technologies to make substantial water savings for the community. This wrapped up the formal proceedings for the event, which then led to the conference dinner at the Lady Bay resort. The food, staff and company were fantastic, with Warrnambool putting on a real show for our guests. With the sun shining on Saturday morning the group set off on a walking tour of the Merri River with Jarred Obst and Stephen Ryan of the GHCMA, who explained the careful management required for the estuaries. Jarrod took us through the effects of human intervention linking to fauna and flora loss. He also explained the effects of flooding events in June 2014 that were the result of a king tide and storm surges with huge winds coinciding to prove catastrophic to roads, homes and other infrastructure along the coast line that stretches from Warrnambool to Portland. Following the walk, we jumped on the bus to visit Warrnambool’s Aquaculture Hatchery. Ben Pohlnor and Tom Kindred from Wannon Water took us through the process that produces millions of young goldfish per year that are then sent on to the juvenile production facility in Hamilton, and ending in the Hamilton WWTP lagoons as a final treatment step to polish the effluent. With the day now heating up we boarded the bus to Port Fairy. Paul Brown of Wannon Water met us at the Port Fairy Water Reclamation Plant, where two treatment trains are located – one for municipal waste and the other for the pharmaceutical company, GlaxoSmithkline (GSK). The waste from GSK is complex and highly saline. Originally it was treated by the main process, but over the past few years the site has doubled in size to manage the complex and increasing waste stream from GSK. By this stage everyone had worked up an appetite and we headed to the local Surf Club for lunch. Ebony Perrin, Environmental Services Team Leader at Moyne Shire, then met us to take us on a walking tour to explore the challenges facing the Port Fairy coastline, and the different mitigation measures that are being employed on a limited budget. Thank you to the organisers Gail Reardon, Jasmine Errey, Virginie Crouzat and Stephanie Rich, our sponsors GHD, Veolia Water and Wannon Water, and all of those who supported the event, spoke, and provided tours to the group. A special mention must also go to our local contact Robbie Frawley of Wannon Water, who ensured that the conference had that ‘local’ touch. We hope to see you all in 2016 for the next regional tour!
