a) Development of sustainable energy-efficient water supply systems in society
Research Project , 2021 – 2024

Sweden's goal is an energy transition, which places demands on efficiencies in all areas. One forgotten area is
water supply, which has looked the same for the past 50 years. Water use gives rise to large energy losses in
obsolete water systems, e.g. 11 TWh / year is used for heating domestic hot water in buildings. There is a huge
potential in innovative water systems. Innovation can reduce both power requirements and energy use, as well as
the load on water sources, distribution networks and sewage management. Today, there is a lack of detailed
knowledge about which system solutions are possible and robust evaluation criteria for this. The goal of the project
is to fill knowledge gaps in this area and present innovative solutions based on interdisciplinary assessment
criteria for energy-efficient water supply systems. Furthermore, system solutions must be demonstrated to verify
project results.
