Mataró, in the Maresme area of Catalonia, has received a study from the Barcelona Provincial Council on how to introduce sustainable urban drainage systems in its green spaces.
The document sets out objectives and design criteria for these systems, after a review of Mataró’s current green infrastructure and drainage network. It notes that 10.7% of the city’s urban land is permeable, below the 30% level considered desirable for water infiltration and natural water cycle management.
The study identifies the most suitable options for different parts of the city, including structural tree pits, floodable flowerbeds, infiltration trenches and wells, detention or infiltration ponds, permeable pavements, artificial wetlands, and vegetated swales with filter drains.
It also covers common materials, construction guidance and maintenance needs. The document proposes an organisational model that sets out responsibilities between municipal services and the operators involved. For more on local coverage, see our news page.
With this study, the Barcelona Provincial Council adds technical support for municipalities working to adapt green infrastructure and use nature-based solutions. Mataró now has a strategic document to help plan and gradually introduce sustainable urban drainage systems.
The council says the work supports a more sustainable and functional urban model, adapted to current climate challenges. It also links the initiative to the UN Sustainable Development Goals, including SDG 3, Good Health and Well-being, SDG 11, Sustainable Cities and Communities, and SDG 13, Climate Action. The 17 goals were adopted by the UN General Assembly on 25 September 2015 as part of the 2030 agenda.
