COMIX: Challenges and Opportunities of Modular water Infrastructures for Greening the Swiss Economy

The Comix project examined the challenges and opportunities of modular infrastructure systems for the Swiss economy and society. The analysis focused on the example of urban water management.

The Comix project was part of the SNF NRP73 funding program on Sustainable Swiss Economy and ran from January 2018 to December 2021.

Problem setting

The Comix project set out with the aim to analyze opportunities and challenges of a more sustainable Swiss economy, which is associated with a foreseeable fundamental shift towards more modular system designs in many infrastructure sectors. The analysis primarily focused on the Swiss urban water management sector, scrutinizing impacts on Swiss industry, utilities, professional associations and regulators. The case of urban water management is particularly well suited to analyze these challenges due to strong path dependencies and considerable impacts on sustainable futures globally. In Switzerland in particular, urban water infrastructures are generally well equipped to deal with the current situation. However, in the near future, challenges, such as climate change with intensive flooding as well as increased urbanization, can put pressure on the current systems in the form of sewer overflows. Therefore, the core research questions that was analyzed in the project relate to in how far the challenges and opportunities of modular infrastructures could represent a first mover advantage for Swiss industry and a strategic chance to anticipate future system configurations for Swiss operators and regulators and in how far synergies between these two aspects could be identified. Ultimately, the aim was to form a hypothesis about the so-called lead market potential of Switzerland in this sector.

Project Structure

The project was subdivided into two research streams and a synthesis module. The first stream aimed at understanding opportunities for Swiss water companies in the context of global industry dynamics associated with modular water technologies, assessing success conditions at both innovation systems and at industry level. The second stream set out to identify challenges and opportunities that modular infrastructures represent for utilities, professional associations, consultancies and government departments, which are responsible for planning and operating UWM structures. More specifically, the project planned to conduct an encompassing cost benefit analyses of alternative transition scenarios from today’s mostly centralized system configuration towards future more hybrid forms. Furthermore, alternative governance structures, including the role of policy instruments and different actors that could enable implementing and operating hybrid system configurations at a similar level of performance like the incumbent system needed to be elaborated and assessed. Through a synthesis module, the results from the two analytical streams could be integrated, assessing the lead market potential.

Practical relevance

For this purpose, Comix was conceived as an inter- and transdisciplinary project run by research teams from various disciplines such as management, economic geography, political science, economics and engineering. Additionally, representatives from industry, utilities, professional associations and government were to be involved in several sequences of participative workshops. Through these workshops, Comix co-develop future scenarios for enabling more hybrid water systems with implications and potential solutions for practice and politics.

Major outputs for practice experts

A major output of this collaborative work, was the “position paper” on the future relevance of modular water systems for the Swiss urban water management sector, which you can find here:

         conceptual framework of how path creation in emerging industries depends on
         the availability of both knowledge and legitimacy. Unlike the extant literat

          countries (India, Israel, Singapore, South Africa, the UK, the US) with dif

' (162 chars) description => protected'The technological innovation systems (TIS) framework is one of the dominant
         perspectives in transitions studies to analyze success conditions and system
          failures of newly emerging technologies and industries. So far, TIS studies
          mostly adopted a rather harmonious view on the values of actors and by this
          were unable to address competition, conflicts and, in particular, battles o
