Research project at HSB Living Lab on innovative stormwater management

RISE, The City of Gothenburg, Gryaab, LTU, Chalmers, HSB and a number of technology suppliers have for 4.5 years run a joint research and development project linked to sustainable stormwater management at HSB Living Lab in Gothenburg.

At HSB Living Lab in Gothenburg, the project has constructed two test sites for evaluation of stormwater facilities. The test site provide an opportunity for technology suppliers to evaluate the technologies' efficiency in delaying stormwater under controlled conditions. Something that enables product development and standardized requirements.

During the project's duration, different types of biofilters / raingardens have been evaluated and data has been continuously collected. The evaluation is unique in its kind as it is seldom possible to measure and evaluate for such a long time under controlled conditions. Evaluation of operation and maintenance of the facilities has also been carried out, something that the industry has clearly requested. The results from the evaluations have formed the basis for a number of research studies, e.g. studies of the potential societal impact of a comprehensive implementation of stormwater retention measures in a larger area. The study shows very good effects, both in the long and short term. The opportunity for technology suppliers to test other types of technology on site will remain after the project's duration.

As suggested by the technology suppliers, the project has formulated a proposal for an industry standard for evaluating the function and sustainability of stormwater facilities. A standard enables technology suppliers to evaluate, develop and market their products in relation to customers and requirements. The standard will hopeffully form the basis for a new Swedish national standard (SNS). Several of the project participants will, together with the Swedish Environmental Protection Agency, try to develop another test site for evaluation of stormwater techniques with regard to treatment.
