Climate change with a warmer climate will place higher demands on the management of drinking water by both municipalities and the population. Municipalities are forced to adapt through both technical and physical measures to cope with water supply. In Sweden, both surface and groundwater are used as drinking water.  The purpose of the study was to map the water strategies of the municipalities Borgholm, Högsby, Hultsfred and Mörbylånga in case of water shortages. Furthermore, the study examines how the management of water shortages differs in the municipalities and how adapted each municipality is to future climates. The study reviewed master plans, VA plans and VA policy and interviews with the municipalities Borgholm, Högsby, Hultsfred and Mörbylånga.  Based on the interviews with the municipalities, it was found that there was a difference between the mainland municipalities and Öland. It showed, for example, that Öland has access to salt water and hence the municipalities on Öland can use saltwater treatment technology, while the municipalities such as Högsby and Hultsfred do not have that possibility. Instead, the mainland municipalities use artificial infiltration to strengthen their groundwater supply. What can also be seen is that almost all municipalities state that they lack a complete waterplan and climate plan. And that future climate change is assumed to be a problem for future drinking water supply.
