Together these factors have entrenched a path dependency in the way water services are supplied and attitudes towards them that must be thoroughly questioned if the current crisis is to be understood and addressed. This book summarises these intersections as a preliminary to the consideration of alternative methods of ensuring a sustainable and appropriate mix of the supply of water services for Australian cities in the future. In Chapter 1, Tony Dingle points out that from the standpoint of today, urban water supply and sewerage systems in Australia appear to have changed little in their technological essentials for extended periods of time. A water-supply authority harvests rainwater or stream flow, stores it, treats it (if required) so that it is potable, and then reticulates it into homes and businesses. The liquid and solid wastes generated there are piped out again, treated to some degree, before being emptied into the ocean. This has usually been explained as an example of path dependence. The technology is expensive and disruptive to install. Once in place it limits future development paths so that it is less costly to expand an existing system as the number of consumers and per-capita requirements grow, rather than replace it with something different. Consumers also are not required to change their usage habits. This generates a set of obstacles both in supply and usage to the adoption of new technologies that differ significantly from what is currently in place. There have, however, been major transitions in the past where cities have replaced existing methods of supply with new and different technologies. The most obvious of these have been the shifts from water delivery by water cart or on-site rainfall collection to reticulation; and from nightsoil collection to piped, water-borne collection by means of flush toilets. These transitions were made by most cities in the developing world between the mid nineteenth and the mid twentieth century. Typically, they were climactic events provoked by widespread concerns, usually about threats to public health. They usually involved an assessment of the alternative technologies available at the time. 1 Troubled Waters: Confronting the Water Crisis in Australia's Cities In examining these transitions, their timing and the factors which provoked them, Dingle raises questions about what might constitute necessary conditions for radical change in today's networked cities. In the light of previous transitions, are they now approaching the critical conditions in relation to water supply and sewerage provision that could push them onto different trajectories in relation to present and future sources of water as well as patterns of water usage? In Chapter 2, Peter Spearritt provides illustrations of the way the rigidities in approaches to the provision of water services and short-term political considerations have influenced the investment in water-services infrastructure in Southeast Queensland (SEQ). He discusses how the Queensland Government reacted to the recent drought and argues that the explanation of the crisis in SEQ lies in an analysis of infrastructure quick-fixes popular with engineers, a remarkable lack of accountability in the water bureaucracies and untold arrogance in the electricity authorities. Spearritt claims that successive bureaucrats and Ministers ignored the warning signs, sounded as early as 1997 by experts in the Department for Natural Resources and Mines. The Government embarked instead on a series of `supply side' projects although the creation of the Queensland Water Commission in 2006 was followed by the introduction of regulations which demanded severe reductions in domestic water consumption. In Chapter 3, Graeme Davison explores the social history of our changing water-consumption habits and behaviour. He argues that the increase in consumption was brought about by the twin concerns of health and morality, reminding us of the strong link between Protestant
