Thomas Pettersson

Centrumföreståndare at

Thomas is associate professor at the Division of Water Environment Technology at Chalmers. His expertise is within drinking water research. Thomas is the director of the DRICKS program, which is a collaboration between Chalmers, University of Gothenburg and Swedish municipalities. DRICKS is a framework project consisting of individual research projects with the objective of providing a safe and healthy drinking water. Research in the entire drinking water system is carried out – from source to tap. Thomas supervises several PhD students.Renewal strategies of drinking water pipes. The project analyzes the need for renewal of water pipes from a health and economical perspective. Modelling of contaminant transport in water sources. The project aims to calculate how much pathogens that are transported to the raw water intake, at the drinking water plant, and the health risks it poses for drinking water consumers. An assessment of which measures are most effective to reduce the risks, from an economic as well as a health perspective, are investigated.
