In a recent post, my colleagues and I reported on our most up-to-date research output in an extended series of projects examining the effect of regulation on water innovation. The post describes a latest framework for understanding and, ultimately, improving relationships between regulators and wastewater utility managers who’re looking for to implement novel technical solutions, and is well price a read. That research caps a decade of empirical work, and offers us a framework on which to construct towards the goal of stimulating a culture of helpful innovation within the wastewater sector.
This post tells the story of how we got up to now, illustrating key themes along the best way: the sensible value of exploratory research, collaboration, engagement, and the potential for developing a community of practice.
2012: Intuition about innovation
Our first effort on innovation began on the inception of the ReNUWIt program, with an article arguing that there may be an innovation deficit within the urban water sector.
That article defined innovation as the event, application, diffusion, and utilization of recent knowledge and technology, and argued that innovation isn’t maintaining with the increasing stressors to the water sector, impairing the sector’s ability to support public and environmental health. Further, innovation is usually conceived in narrow terms that emphasize only technological change. We argued that the pathway to innovation lies through institutions, relatively than latest technology development alone. A spread of other work followed this paper, including an influential legitimacy framework for innovation.
2016: Survey as blunt instrument
We dove deeper into the perceptions wastewater managers in California hold about innovation. Figure 1 summarizes their perceptions of barriers to innovation.
This research precipitated a breakthrough after I met Dave Smith, then at US EPA. Once I showed him the manuscript, Dave immediately pointed on the third bar on this figure and said “I need to know more about this.”
2020: Survey as scalpel
The EPA Office of Science and Technology and the National Science Foundation ReNUWIt program funded our group to concentrate on the connection between regulation and innovation. Our team designed parallel national surveys to look at the views of regulators and wastewater utility managers about this nexus.

Our first set of results from these surveys focused on utility managers’ responses. The evaluation disentangled the concept of regulation into several component parts: regulatory requirements, regulatory relationships, and the regulatory environment (Table 1). Our results contradicted anecdotal expectations on a vital point: utility managers didn’t think reducing regulatory stringency would do much to encourage innovation. As a substitute, the outcomes pointed to the importance of regulatory relationships.
2021 – Survey as diagnostic
We then compared utility managers’ perspectives to those of regulators, finding that “regulators and utility managers agree about barriers and opportunities for innovation within the municipal wastewater sector.” This result challenges one other widely held assumption, that the 2 communities hold oppositional views on innovation. This matters since the successful adoption of recent technologies requires support from each regulators and utilities. The belief of conflict can, in and of itself, hinder cooperation. By difficult a destructive trope of conflict, this work points the method to potential actions to enhance the relationships between regulators and people they regulate.
2023 – On the (latest) starting line
That brings us to the current.
The work that opened our story provided us with a novel empirical take a look at the innovation process. More importantly, it set us up perfectly to make good on the final word goals of this research – using research insights to catalyze shifts in practice, ideally helping thought leaders, and practitioners more broadly, act otherwise in service of helpful innovation. Regulatory relationships are a key doorway for creating this alteration.
So we’re off once more. Our current goal is to pivot from in-depth research to designing strategies and tools for empowering regulatory agencies, wastewater utilities, and other interested stakeholders to have interaction effectively in regulatory processes around modern technologies and approaches. Our team is currently constructing on our catalog of research and other related work. US EPA and ReNUWIt have doubled down by committing seed funding for us to map out a concerted effort to implement the insights now we have developed over the past decade. We at the moment are working to challenge inaccurate assumptions of inherent opposition between regulation and innovation. We’re applying our insights through engagement with a variety of key stakeholders, and collectively examining a more collaborative approach to permitting.
Ultimately, bounded flexibility, with each words carrying essential weight, would be the key to enabling utilities to do things otherwise, to social and environmental profit. Ideally, this work will enable wastewater utilities to serve their communities more effectively, at a lower cost, and, often, with multiple co-benefits. Improving regulatory relationships is a critical pathway for actualizing this vision, and we imagine now we have identified key strategies to assist make that occur. Stay tuned for more as we expand our engagement on this topic.
Onwards!
This post reports on efforts to look at regulation and innovation within the municipal wastewater sector, funded by US EPA and the National Science Foundation ReNUWIt Engineering Research Center. Support from a variety of industry groups was crucial, including National Association of Clean Water Agencies (NACWA), the Water Research Foundation (WRF), the Water Environment Federation (WEF), the California Association of Sanitation Agencies (CASA), and state and regional chapters of the Water Environment Association (WEA).
