At Unitywater, we take the responsibility of providing our customers and our communities with a safe and reliable water supply seriously. From meeting our compliance obligations and investing in infrastructure through to championing environmental initiatives, Unitywater continues to build a proud record in the delivery of our food grade water product. This year we continued to work collaboratively with Seqwater, our service region’s bulk water supplier, to upgrade the water supply for the community of Petrie and surrounding areas. This significant engineering project ensured a greater security of supply for residents through the decommissioning of the ageing Petrie Water Treatment Plant and connecting this community directly to the South East Queensland Water Grid. The success of this project was also measured by the minimal impact caused to the community which helped enhance customer confidence in our operational performance. Unitywater is also building a reputation for our commitment to reducing the impact of single-use plastic bottles in our local waterways. We’re encouraging our communities to go ‘Back to Tap’ through the promotion of reusable water bottles and selecting tap water over pre-packaged bottled water. As this report confirms, our drinking water meets Australia’s best-practice guidelines developed by the National Health and Medical Research Council. Some people believe that bottled water is a better-quality product, however this is simply not the case. With bottled water up to 2000 times more expensive than tap water, it is an easy and practical choice to make to embrace ‘Back to Tap’. We value the role we play in keeping our communities healthy and are proudly working 24 hours a day, 365 days a year to provide a safe and reliable water supply. If you have any questions or feedback on the content of this report, please do not hesitate to call our Customer Contact Centre on 1300 086 489.
