Politics, water management and infrastructure.

While modern water management has been central to the achievement of a range of beneficial social outcomes, it has increasingly drawn criticism for its disconnection from democratic decision-making, hindering efforts to develop more resilient systems. This paper examines how an experiment with more resilient water infrastructure politicized centralized water management focusing, in particular, on a stormwater re-use 'third-pipe' system at a large residential development in Auckland, New Zealand. Through analysis of resident and expert views on safety, cost and security, the paper attends (1) to the ways in which techno-managerial water management was contested and, thus, politicized through the implementation of the third pipe, and (2) how the mobilization of techno-managerial discourses by water management authorities delegitimized the third-pipe system, rendering it ultimately inoperable. While our case study was thwarted by the de-politicizing apparatus of water management authorities, such experiments offer precedents, resources and hope for more democratic systems of water management.
