An incremental approach to service co-production: unfolding the co-evolution of the built environment and water and sanitation infrastructures

The literature is increasingly approaching the participation of households in the delivery of urban services through the lens of co-production. However, there has been no in-depth exploration of the relationship between incremental changes in the urban fabric (urban typologies and morphologies) and the forms of adaptations of co-produced water and sanitation services (WSS). The paper draws on three planned neighbourhoods in Hanoi to examine these incremental changes by considering the transformation of the neighbourhood at different scales and the consequent evolution of the sociotechnical arrangements for the delivery of water and sanitation services. By exploring forms of reconfiguration of the built environment and embedded water infrastructures, the paper outlines the possibility of an alternate reading of service co-production initiatives as incremental spatial practices, with an emphasis on the role of technology in allowing transformation processes.
