Analysis of institutional work on innovation trajectories in water infrastructure systems of Melbourne, Australia
Introduction
Complex infrastructure systems such as water, energy and transportation are facing immense sustainability challenges globally. Impacts of climate change, population growth, ecosystem degradation and resource limitations are having significant consequences for how well these systems can deliver services that adequately meet societies’ needs (e.g. Bates et al., 2008, Frantzeskaki and Loorbach, 2010, Westley et al., 2011). Despite a growing scholarly and practical awareness that fundamental changes in urban infrastructure systems are required (e.g. Chapin III et al., 2010de Graaf and van der Brugge, 2010, Pahl-Wostl, 2009, Truffer et al., 2010), sectors are locked into their current approaches due to barriers such as path-dependencies, institutional inertia and inadequate actor capacity to engage in new practices (Berkhout, 2002, Farrelly and Brown, 2011, Frantzeskaki and Loorbach, 2010, Pahl-Wostl, 2009, Westley et al., 2011). To overcome these challenges, scholars argue it is critical to support the emergence, up-scaling and stabilisation of innovative technologies and practices that increase the sustainability of urban infrastructure systems (Frantzeskaki and Loorbach, 2010, Pahl-Wostl, 2009, Truffer et al., 2010).
Transitions studies focuses on addressing path-dependencies, with particular attention on trajectories towards new socio-technical regimes that are likely to encompass a range of innovations. In recent years, this scholarship has advocated that further explanatory detail on the role of agency in stimulating and steering the maturation of innovations is needed (e.g. Brown et al., 2013, Farla et al., 2012, Grin et al., 2011, Markard et al., 2012). An institutional lens that focuses on the institutional structuring processes that actors put in place may contribute to developing this more agency-centric perspective for understanding processes of transitional change (e.g. Brown et al., 2013, Geels, 2004, Geels and Schot, 2007, Truffer et al., 2009).
In this study, we define an innovation as a new technology and associated practices within an existing infrastructure system, which provides an alternative utility (e.g. harvested stormwater runoff or recycled wastewater as new city water supplies). Following Geels and Schot (2007), it is possible that innovations could reinforce and/or disturb the established regime of the infrastructure system, depending on whether their nature is as a replacement, or as a competence-enhancing add-on. Realisation of the innovation's utility is likely to depend on the role of agency and associated institutional structuring processes mediating the dynamics between the innovation and the regime.
From an institutional perspective, the maturing of an innovation is reflected by the development of a new set of institutions that could co-exist or undermine those of the established regime. Drawing on Scott's (2008) new institutionalism research, an innovation that is fully institutionalised would be characterised by a mature suite of mutually supportive cultural-cognitive, normative and regulative structures, which collectively provide the ‘rules’ for reinforcing its realisation within the infrastructure system. The efforts to develop this suite of structures has been described as ‘institutional work’, which brings focus to the role of deliberate agency in creating, maintaining and disrupting formal and informal institutions (Lawrence and Suddaby, 2006, Lawrence et al., 2011). The evolution of institutional work in relation to the maturity of an innovation is yet to be explored.
The aim of this paper is therefore to develop the first set of hypotheses on the type and purpose of institutional work needed to establish innovations within an existing infrastructure system. To do this, the paper focuses on how institutional work to create new institutions evolves between key stages (i.e. from pre-niche, to niche, to niche-regime, to regime) during the maturation of innovations. Three innovations were selected as empirical case studies with different institutional alignments (reinforcing and/or disrupting) with the established regime to ensure an internally valid and reliable base for hypotheses development.
The study context is the water system of metropolitan Melbourne, involving a system-scale empirical analysis of the dominant patterns of institutional work that reflected the maturing of desalination (reinforcing), wastewater recycling (reinforcing and disrupting) and stormwater harvesting (disrupting) between 1997 and 2012. These innovations emerged as novel and qualitatively different to the status quo, attracting variable levels of public confidence and controversy as alternative water supply approaches. The three case studies, treated as innovations, were therefore considered ideal for this research.
Contrasting within and across these cases allowed for generalising and, subsequently, deriving hypotheses on the dominant patterns of institutional work for maturing innovations. These hypotheses may also contribute to the identification of preliminary indicators of the type and direction of agency required for navigating transitions (Brown et al., 2013). While the empirical analysis led to development of rich descriptions and explanatory detail of agency-related activities (such as individual strategies, networks development and political positioning), this was for the purpose of identifying the types of institutional work employed. Therefore, this paper does not report on the agency of individual actors and their associated power dynamics, but rather the institutional structuring patterns as a result of this activity.

Analytic framework
This research adopted the multi-pattern approach (de Haan and Rotmans, 2011, de Haan, 2010) as the conceptual architecture for framing the overall study and individual cases. This framework conceptualises that a societal system is comprised of co-existing subsystems (known as constellations) that interact (Fig. 1a).
Individual constellations are distinguishable by the service(s) they deliver and the way in which the service is delivered. Each constellation functions to meet societal needs with
Research design and approach
Examining the phenomena of institutional work is highly contextual and therefore relies on the triangulation of multiple forms of evidence that have been subjected to internal and external validity testing (Yin, 2009). As such, the research design was a multiple-case analysis within a common socio-political and sectoral context.
Case narratives
This section describes the institutions and infrastructure of the established regime and each of the three innovations. A short chronological narrative of the institutional work that enabled the maturing of the three innovations over the case study period is also presented. A full account of changes in Melbourne's water system during the case study period can be found elsewhere (Ferguson et al., 2013a).
Innovation-regime alignment
Table 5 characterises the institutions that support the functioning of the regime and the three innovations according to the institutional indicators used throughout the study. Comparison of these characteristics across the categories of institution types determines the alignment of each innovation with the established regime (Table 6). For example, the ‘community of practice’ is water supply engineers for both the established regime and desalination, while for stormwater harvesting it is
Conclusions
This paper represents one of the first empirical explorations of the relationship of institutional work to innovation maturity within an established infrastructure regime. Through analysis of three case studies of innovation in the context of transitional change in Melbourne's water system, the purpose and type of institutional work that created new cultural-cognitive, normative and regulative institutions was traced through key stages of maturity.
The paper has shown that the type of
