Water provision and wastewater treatment are crucial for the survival of human beings. Having access to safe drinkable water responds to an essential human need. This chapter builds on our alignment framework, in order to investigate the second layer of our framework, which concerns the alignment between the technological design of a network infrastructure and the meso-institutions that regulate its domain of action. As argued in the previous chapters, we consider governance to be a key concept in understanding the alignment or misalignment within this layer. We investigate the issues at stake through a careful study of the Singaporean water and wastewater infrastructures. Indeed, beyond its spectacular success, Singapore provides a rich example for better understanding modalities that allowed an initially poor country to align the institutional rules framing the organization of its water and wastewater network with the variety of technological solutions selected to overcome the dramatic scarcity of its resources. Through this analytical narrative, our chapter shows the combination of entities and devices that underpin the modalities of governance, through which context-specific technologies and specific institutional norms and rules can be either successfully aligned or suffer from misalignment.
