Understanding and improving processes for Integrated Urban Water Management strategies in Australia A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Lachlan Thomas Hutton Guthrie Bachelor of Engineering (Civil) (Honours) RMIT University School of Engineering College of Science, Engineering and Health RMIT University July 2018 Declaration I certify that except where due acknowledgement has been made, the work is that of the author alone; the work has not been submitted previously, in whole or in part, to qualify for any other academic award; the content of the project is the result of work which has been carried out since the official commencement date of the approved research program; any editorial work, paid or unpaid, carried out by a third party is acknowledged; and, ethics procedures and guidelines have been followed. I acknowledge the support I have received for my research through the provision of an Australian Government Research Training Program Scholarship. Signed: Lachlan Guthrie Date: 17/07/2018 Lachlan Guthrie – PhD Thesis III Acknowledgements Firstly, I would like to thank God and acknowledge that were it not for His grace I would not be where I am today. This thesis was very much dependent on the generous assistance that I have received from others. Foremost, my friend and colleague Casey Furlong, another PhD candidate at RMIT who has finished. Casey and I worked closely together in the early stages of the research, refining the objectives of both our research projects. As can be seen, Casey and I have authored many publications together and without his support this thesis would not be where it is today. Further, I would like to thank my supervisors Dr Saman De Silva and Dr Nira Jayasuriya, and RMIT – without their support and encouragement over the years, this thesis would never have been started let alone finished. As this thesis has been largely reliant on case studies examined through consultation with water industry experts, the case study contacts deserve significant thanks. Without their input this research could never have been completed. They are: Tony Overman, Steven Wallner, Vicky Barmby, Ralf Pfleiderer, Victoria Hart, John Chambers, James O’Connor, Glyn Ashman, Keith Johnson, Alan Watts, Sing Fu, Emma Rose, Anna May, and Kein Gan. I would also like to acknowledge 43 water industry experts that I consulted with over the duration of my candidature, who provided interesting and eye‐opening opinions on the water sector and helped guide the research – thank you for your valuable time. Their generous sharing of their years of knowledge, invaluable insights, well‐directed opinions, and questions helped in forming the methodology and hypothesis investigated during this study. Of particular note I would like to thank Robert Considine of Melbourne Water, who has gone above and beyond to support me and my research. I would also like to thank Nick Brown for his valuable contributions as well. Finally, I would like to thank my family, in particular, my father Ken Guthrie and my mother Cathy Hutton. Not only for the times during this thesis, but the countless times over the 28 years of my life, that they have been supportive and encouraging. All the publications in this thesis are co‐authored and for some I am not the first author. Table I explains my contribution to each publication.
