Reduce costs for water treatments

The CLEVER Way: Hamburg, Neugraben-Fischbek

The CLEVER Cities project identified the primary planning goals for Neugraben-Fischbek district located in the South-West of the city of Hamburg was to: (a) creating a connective ‘Green Corridor’ to link a system of NbS interventions; (b) establishing horizontal greenery through the construction of green roofs on existing buildings; and (c) address the topic of environmental education and connect the youth with nature. 

Hamburg has aimed at addressing the following challenges, including:

  • Increase biodiversity and nature in the city: To address this, the city

  • ...

Las Llamas Park, Santander: Wetlands and permeable car parks

Panoramic view of the Las Llamas Park. In the right, the east side with the Palacio de Deportes, at the left, the west side with the Arenas bridge.

The D4RUNOFF project’s goal is to create a novel framework for preventing and managing diffuse pollution from urban water runoff. This will be achieved by designing hybrid nature-based solutions (NbS) and a data-driven AI-platform to support policy and decision making.

The case studies have been identified for the implementation and validation of this approach in varying environments. The replicability of these results will then be assessed at five replication sites. The Las Llamas Park in Santander has been chosen as one of three case study sites as part of the D4RUNOFF project.


Amplification of the self-purification capacity of a small urban river using a natural solution to reduce the effect of urban stormwater degradation on its ecological status (France)

Porous ramp operating at medium flow with  sand accumulation upstream

Ecohydrological engineering is used here to enhance the self-purification capacity of a small stream polluted by urban rainfall discharges. The demonstration site, realized in collaboration with the stakeholders, shows the positive effect on the chemical quality of the stream




Green Noise Barrier Sachsenheim, Germany

The noise barrier wall-system being used in Sachsenheim guarantees an instant green noise barrier wall, from the very first day on: The green noise barrier consists of a scaffold with galvanised steel lattice mats on both sides, filled with a core of plant substrates and then planted with pre-cultivated plant mats. Already at the time of assembly, the walls are at least fifty percent covered and they are completely green after six months.


Ecuador: INNOQUA demo site in Quito

INNOQUA is a four-year EU-funded Horizon 2020 project. Bringing expertise from multiple disciplines, the 20 project partners are seeking to demonstrate a novel, modular system for wastewater treatment based on the purifying capacity of earthworms, zooplankton and microalgae, operating under real conditions.

Due to its modular configuration, the INNOQUA system can address multiple aspects of wastewater treatment and water re-use in water stressed communities, rapidly expanding cities and industries – both in developed and developing countries. The decentralised approach helps to...




Canal and North Gateway

Green Infrastructure Strategic Intervention: Canal and North Gateway

Extensive community engagement sessions were conducted from 2015-2016 by Scottish Canals and Glasgow City Council, including a charrette at Port Dundas which recognised the role green and blue infrastructure could play in regenerating the area. As a result of this, plans to develop the area included extending the path network, re-designing entrances, installing boardwalks, creating picnic areas and building a bridge across the canal to improve access.

The second part of the project is the ‘Smart Canal’ and this forms part of the North Glasgow Integrated Water Management System and...
