Odense Case Study

Odense, Denmark

Led by VCS & University of Southern Denmark

Local stakeholders: Ministry of Environment of Denmark, Environmental Protection Agency, Odense Kommune, Odense Boldklub and local residents

The case study is located in the Bolbro area in Odense. It is undergoing a large transformation (i.e. demolition of large industrial areas, construction of dense housing and green infrastructure). The overflow receiving water bodies (Bolbro Rende/Odense Fjord) do not meet the requirements set out by EU Water Framework directive (thus, stormwater outlets are being restricted) and monitoring of the network is limited.

The local recipient is a small creek (Bolbro Rende) in an urban setting. The pollution load in this creek is already under study. Several initiatives have been undertaken and are being planned to reduce this pollution load.

Several Nature-Based Solutions (NBS) have already been implemented in the area, mainly bioretention facilities (rain gardens with filter soil) with and without underlaying drains. These facilities have different types of catchment areas, for example a primary road with heavy traffic; a secondary road with less traffic and parking lot.

Some of the nature-based solutions in the area have been monitored, and D4RUNOFF will use these established monitoring facilities. Data from these projects can be used in D4RUNOFF if needed.

Finally, residents in the area have been involved in different projects over the last years, many incorporating nature-based solutions. The community will continue to be engaged with through D4RUNOFF.

Objectives

Implement and assess of new NBS: rain gardens with filter soil integrated in the roads for collecting, filtrating, infiltrating, and discharging storm water (existing: 20-30)

Carry out non-target analysis to determine the presence and number of specific contaminants and CECs (this includes the concentration of various metals as well as the presence of multi-resistant bacteria) and track their source and fate before stormwater outlet to the receiving water bodies

Incorporate new sensors to enable data gathering

Develop water sampling techniques in existing ponds and NBS to evaluate its effect on the CECs

Test and validate the project results in a relevant environment

Assess the replicability of the project results

Solutions implemented

High-resolution methods for suspect and NTS for CECs

Developed by VCS

Online sensors for water pollutants

Developed by INL Laboratory

MCDA applied to dynamic design of hybrid urban drainage solutions

Developed by VCS

DSS applied to hybrid urban drainage solutions, ABM and social network analysis

Developed by ITG
