Water Innovation

Urban water systems in California need to adapt in response to changing climate, population growth, aging infrastructure, and other challenges. Adaptation will require innovative ways of managing and identifying beneficial linkages between environmental water quality, drinking water supplies, wastewater, stormwater, flood control, and other aspects of urban water.

This initiative examines barriers to urban water innovation, with an emphasis on direct potable reuse, and explores ways to constructively address them.

Of Dreamliners and Drinking Water: Developing Risk Regulation and a Safety Culture for Direct Potable Reuse

This paper examines the notion that emerging regulation of DPR may lack sufficient attention to a particular class of risks: catastrophic risks with low probabilities of occurrence, but high consequences. We argue that proponents of DPR could benefit from proactively developing a safety culture in DPR utilities and establishing an effective industry-wide auditing organization that investigates unanticipated system failures. Developing independent oversight for DPR operation could ensure that stringent quality and management requirements are set and enforced, and that any system failures or “near misses” are investigated and adequately responded to.

Barriers to Innovation in Urban Wastewater Utilities: Attitudes of Managers in California

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges—faster innovation will need to be part of these transitions. The results in this report reveal insights about the attitudes towards innovation among decision makers in the wastewater sector, and how perceptions at the level of individual managers might create disincentives for experimentation.

The Thorny Road to Technology Legitimation — Institutional Work for Potable Water Reuse in California

This paper addresses this gap between technological innovation and societal legitimacy by proposing an analytical framework for the early technology legitimation phase that combines recent insights from innovation studies and institutional sociology. The framework we put forward in this paper conceptualizes technology legitimation as being enacted by different actors in a technological innovation system through specific forms of institutional work. This framework is illustrated with a case study on potable water reuse, in this case the injection of treated wastewater into drinking water reservoirs — a technology most consumers confront with revulsion. We outline how the legitimation process interrelates with other core development processes of a technological innovation system and discuss how our framework informs recent work in innovation and transition studies.

Beyond User Acceptance: A Legitimacy Framework for Potable Water Reuse in California

This study takes a broader perspective on the adoption of potable water reuse based on concepts of societal legitimacy, which is the generalized perception or assumption that a technology is desirable or appropriate within its social context. To assess why some potable reuse projects were successfully implemented while others faced fierce public opposition, we performed a series of 20 expert interviews and reviewed in-depth case studies from potable reuse projects in California. Results show that proponents of a legitimated potable water reuse project in Orange County, California engaged in a portfolio of strategies that addressed three main dimensions of legitimacy.

Accelerating Cost-Effective Green Stormwater InfrastructureAccelerating Cost-Effective Green Stormwater Infrastructure: Learning from Local Implementation

Although green stormwater infrastructure (GSI) is critical to solving stormwater management challenges, GSI is evolving technology with inconsistent performance and uncertain costs. Our report recommends enhancing learning from local implementation efforts to address knowledge gaps and speed cost-effective deployment. We identify key actions the EPA and state water quality authorities can take to help drive data collection and sharing.

Reducing the innovation deficit in urban waterThe Innovation Deficit in Urban Water

Arguably, the main barriers to developing the new technologies and management practices necessary to meet emerging challenges in the water sector will be institutional rather than technical. In collaboration with ReNUWIt researchers and others, we are working to characterize barriers to innovation, and opportunities to overcome them, including legal, regulatory, social, financial, governance, and others. We have produced a “most readarticle that develops a framework for forthcoming studies on the institutional elements of innovation at various scales.  We have also investigated potable water reuse for water supply augmentation, using the concept of legitimacy to develop a broader framework for what is necessary to implement water reuse projects.
