The city of Bremen has taken on new rainwater management approaches in order to preserve natural resources, reduce pressures on the sewer systems, reduce the consumption of drinking water, and more broadly, adapt to climate change).

Bremen is applying split fees for rainwater and wastewater. It provides a refund if properties are less sealed and rainwater can filtrate into the soil or rainwater is used. In addition, the city is subsidising investments into rainwater use in toilets, garden irrigation, collection tanks up to 12.000 Euro or a maximum of 1/3 of the total investment costs per household.
