Abstract

Different researchers have shown that rising global sea levels have to be expected in the course of climate change. Long-life infrastructures such as sewer systems therefore face new challenges in coastal regions. The influence of rising sea level on sewer systems has been acknowledged but has not yet been described in detail or even quantified. In the present study, a correlation between sea level fluctuations and wastewater conductivity will be investigated. By implementing mixture calculations this correlation will be used to develop an empirical model to predict wastewater conductivity out of sea level data and flow measurements. The results of these calculations for the municipality of Gothenburg show that the theoretical seawater inflow would not influence the treatment capacity of the wastewater treatment plant (WWTP) negatively. However, it became evident that seawater inflow is an existing process in coastal regions like Gothenburg. Smaller WWTPs might not be able to compensate these inflows. The developed model can therefore be a useful tool to estimate possible weaknesses of a system. Future research lies mainly in the improvement and increase in robustness of the model. By combining the improved model with climate scenarios, future challenges can be identified and the planning process for sewer systems can be improved.
