Integrated water resources management (IWRM) has emerged as a popular ideology in the water sector since the 20th century. From a highly techno-centric approach in the past, it has taken a new turn worldwide, following a Habermasian communicative rationality, as a place-based nexus for multiple actors to consensually and communicatively take decisions in a hydrological unit. This communicative practice expects to be consensual, stable and static in integration of water management. This how IWRM should be approach had a remarkable appeal worldwide as promoting authentic participation of all stakeholders in integrating water management. Its Foucauldian critiques argue how IWRM cannot be achieved given the power dynamics in social interactions. The critiques reveal that the domain of water resources management is a discursive terrain of collective action, contestation and negotiation, making water management a socio-political process, where there are multiple forms and meanings of integration.
