Abstract
Heavy precipitation can lead to numerous challenges, including sewage overflows, mixture of rainwater and wastewater. Sewage overflows contain chemicals and viruses, damaging the environment, and human health and decrease the quality of water bodies. Therefore, this thesis employs the concept of nature-based solution (NBS) as an environmentally friendly and cost-effective solution to manage diluted wastewater and purify it in Nørre Nissum located in Lemvig municipality. To successfully implement an NBS an analytical framework has been made which contains guidelines from the International Union for Conservation of Nature (IUCN), a risk assessment framework, and a framework that is based on an adaptation pathway. To evaluate and select the best measurement a systematic approach based on adaptation pathways, namely multi-criteria analysis has been used to evaluate and select the best measures, ensuring alternative solutions if one fails. Furthermore, this thesis not only designs an NBS, but also provides a comprehensive formula for dimensioning it for wastewater retention. However, the solution can accommodate the short-term hazard, and Lemvig municipality should use another approach for the long-term solution.
