regular features 62 JULY 2011 water assessments, a major recycled water project and a complex program of water pressure regulation. In the first year of the water mains renewal program, NetWorks Alliance was faced with the potential for the presence of live electricity or electrical currents on the water pipes. In order to address the issue of neutral integrity faults NetWorks Alliance adopted a multifaceted approach that has evolved over the course of the project. The alliance developed "Plum-Guard", an innovative mechanism that allows a non-electrician to be able to reliably test if dangerous voltage is present on a water main. From a safety perspective, it will mean crews are not exposed to an unsafe voltage on the water main. NetWorks Alliance is fully committed to an "incident and injury free" workplace culture, which is inherently embedded in the way that all works are carried out. The Water Industry Safety Excellence Award is jointly supported by: Australian Stockholm Junior Water Prize This is an annual water science competition for senior high school students focusing on projects aimed at improving the quality of life through improvement of water quality, water resources management, water protection and water and wastewater treatment. Mathuja Bavanendrakumar of the Queensland Academy for Health Sciences for the project Eutrophication of Waterways from Golf Course Runoff This study investigated whether phosphate runoff from golf courses contributes to eutrophication in adjacent waterbodies. Seven golf courses with internal lakes were randomly selected on the Gold Coast, and for each, a waterbody in a 1km radius was also selected. Three water samples were taken from each of these 14 waterbodies, and were tested for phosphate concentration as well as algal growth. Results showed all internal lakes in the golf courses and adjacent natural waterbodies tested had eutrophication, indicating moderate to high risk of algal blooms. It was concluded that it is likely that runoff from golf courses contributes to the phosphate eutrophication of natural waterbodies. As such, recommendations can be made to golf courses, such as switching to the use of low- phosphate fertilisers, or the introduction of a water treatment system or reed bed. This project method could be used in order to measure phosphates in other waterways, and could also be used to help identify other types of point source pollution. The Australian Stockholm Junior Water Prize is proudly sponsored by: National Sponsor: Utility Sponsors: National Undergraduate Water Prize This award aims to encourage and reward students for excellence in the field of water studies and research, and provides a forum for students to display their academic excellence and research findings to future employees, clients and the water industry. Chris Browne of Australian National University (ACT) for the project Developing Transfer: Improving Household Water Supply in Rural Cambodia Clean water is requisite for life. In locations where no centralised water system exists, household-level ceramic filtration is utilised to access water free of pathogens. This technology is both low-cost and simple to manufacture locally, making it an ideal candidate technology to deliver clean water in developing countries. Despite this, the innovation in the field experiences disuse over a short time interval. This paper asserts that this disuse is a breakdown of technology transfer, and provides a framework for improving usage rates and, in turn, the health of its users. The National Undergraduate Water Prize is proudly sponsored by AWA Award for Best Ozwater Paper This award recognises the author(s) of the best paper at the annual Ozwater Conference and Exhibition. Lionel Ho of SA Water for the paper Performance of GAC Filters for the Treatment of River Murray Water (see page 65). AWA Award for Best Ozwater Poster This award recognises the author(s) of the best e-poster at the annual Ozwater Conference and Exhibition. Sabrina Woon and Maazuza Othman of RMIT University for the poster Biogas Production Potential from Meat Processing Plant. -- Special Report Kevin Young of WSAA with members of NetWorks Alliance.
