The impact of infiltration and inflow on wastewater treatment plants: A case study in Sweden

Gerly Hey, Karin Jönsson, Ann Mattsson, 2016.

Literature regarding the concept of infiltration and inflow to sewer systems with special focus on how
it affects the wastewater treatment and wastewater treatment plants were searched through online
journals and databases, reports and interviews. The goal was to gain understanding of how the issue is
handled in different regions and what the perception and knowledge of the issue is. We also wanted to
find out how infiltration and inflow, and the effects of it, is regulated in different parts of the world to
be able to understand what can be learnt and applied on the Swedish scenario. In order to better
understand the Swedish condition, a comparison of flow data to some (self-selected) Swedish WWTPs
was analyzed.
