A strategic management of water is integral for any society aiming at moving towards sustainability. This thesis aims to provide a common understanding of how water management should be considered within sustainability constraints, using ‘backcasting’ from basic sustainability principles as a compass. With a common language, a constructive dialogue is then possible to unify all stakeholders to move together towards sustainability. To answer the research question “How can an interaction with water stakeholders be strategically developed to progress toward the service of water in a sustainable society”, a methodology based on Sustainability Life Cycle Assessment, the Template for Sustainable Product Development and Multi-Stakeholder Platforms has been utilised within one domestic and one industrial water user case study in Blekinge, Southern Sweden. In this locality, water is regarded as abundant in volume. Yet it was revealed that what is consumed by society is not water as such; but the purity of water. Within this context, opportunities to move towards sustainability have arisen and the case study organizations were able to utilise improvements in reporting and operations. Economic activity such as new infrastructure, pollutant trading schemes and product accreditation are amongst the many concepts identified as potential steps towards the service of water in a sustainable society.
