Mathare as an informal settlement of the Global South which suffers from an inconsistent water supply and periods of scarcity, relies for its provision on water vendors. This dissertation strives to advance scholarly debates on understanding the production and governance of the ‘actual water supply’ beyond and in relation to the centralised piped water network, and to thinking the conditions for possible change to modes of water supply. An empirical investigation was conducted on certain temporalities of change and continuity in the relational practices of governance actors of the water provision, the water vendors, situated in the informal settlement of Mathare in Nairobi, Kenya. As such, experiences of water scarcity among the water vendors are suggested to contribute to shape Mathare’s water provision by motivating practices circulation, especially regarding water storage. The water vendors might also crucially sustain and re-configure rules, interact with, and be affected by artefacts involved in the water infrastructure through practices of maintenance, repair, but also decay through temporary events of water infrastructure disruption. In turn, looking at relations shaping the water governance, stable relations are suggested to be re-produced through ‘twilight’ actors and temporal modalities in the water infrastructure.
