WS1 | Treatment wetlands and water reuse: from potential to implementation
Water reuse is an increasingly important aspect of sustainable water management. Treatment wetlands have a massive potential for providing water for reuse in future circular and smart cities. This workshop will present the status of treatment wetlands in terms of water reuse (both within the EU and internationally), identify barriers to implementation, and explore the steps needed to accelerate the uptake of treatment wetlands for water reuse. An outcome of the workshop will be the formation of a group of authors willing to produce a white paper on treatment wetlands and water reuse.
Organiser: Dr. Jaime Nivala (INRAE Lyon, France), Dr. Pedro Carvalho (Aarhus University, Denmark)
WS2 | Vertical Space Exploration Social, Financial and Legislative Barriers and Solutions for the Launch of Green Walls for Wastewater Treatment in the Built Environment
Technical advancements of green walls may be achieved by researchers and entrepreneurs alone, however, the social, financial and legislative barriers require the concerted effort of a range of stakeholders and experts to solve them.
After a brief intro to the state of the art, a public sector representative will outline the legislative framework and imminent barriers. Experiences with citizen engagement will complete the picture.
Based on these insights, speakers and participants will embark on an interactive open panel discussion, to integrate perspectives and potentially uncover new solutions and stakeholder collaborations that enable the green wall community to reach new orbits.
Organiser: Dr. Marco Hartl (COST Action Circular Cities “Green wall cluster”)
WS3 | LIFEPOPWAT, development of “Wetland+” technology, a new treatment tool for the removal of HCH and its transformation compounds
Hexachlorocyclohexane (HCH) isomers and transformation products are serious environmental problems around the world. HCH production across Europe has led to more than 40 mega-sites of waste, exceeding 250.000 tons. Most of the sites are not contained and a source of diffuse pollution. Wetland+ has been developed to treat HCHs compounds effectively.
The workshop aims at presenting the results of the first two full sites constructed in the Czech Republic and Poland, treating HCH polluted water leaching from large deposits.
Additionally, we will present an inventory of existing sites around the world where the technology can be of use.
Organiser: Dr. Carlos Arias (Aarhus University, Denmark)
WS4 | The PAVITR project - an India-EU cooperation
The objective of the workshop is to present the result of the PAVITR project where Indian and EU partners are developing cost-effective & sustainable solutions to tackle water challenges and ensure the provision of safe water reuse and the recovery of resources form wastewaters.
PAVITR develops management strategies to enable monitoring of pollution real-time, Most of the technologies implemented are treatment wetland based that can adapt to Indian needs while effectively treating polluted waters.
The projects will assess and validate different wastewater and water management plans, technical aspects, financial, environmental and institutional sustainability to build capacities building capacity

WS5 | Nature-based design of water circularity across the building-community-landscape scale: a real-world mountain lab
This workshop stimulates a holistic co-design experience on nature-based solutions for water circularity across scales. We report the systemic water design of the MonViso Institute (MVI), a real-world laboratory for regenerative design in the Italian Alps. The circularity design uses mechanic and plant-based solutions that are scalable, enclosing fresh water, grey and black water cycles. Specific foci are on the role of human intervention, systemic effects and scalability of solutions for the adjacent wetlands, embedded in a village with many such hamlets, situated in the catchment water shed of the High Po River Valley, Monviso UNESCO Nature Park.
Organiser: Prof. (AHO) Dr. Tobias Luthe (ETH Zürich, Switzerland)
WS6 | CWetlandsdata - Towards the 'Constructed Wetlands Knowledge Platform' for sustainable development
About 80% of all global wastewater is released untreated into the environment. Objectives 6.2 and 6.3 of the Sustainable Development Goals (SDGs) aim to provide universal access to sanitation and improvement of water quality. Constructed Wetlands (CWs), a nature-based solution (NbS), can contribute to these goals. There is currently little knowledge about the contribution of CWs to the global amount of treated wastewater. The global Constructed Wetlands Knowledge Platform was already installed and is currently further developed. We would like to involve the expertise of the workshop participants to develop the database according to the demands of users and stakeholders.

WS7 | Setting full sail towards future resilient cities: Strategies to apply NBS to close water and nutrient cycles within the green-blue-grey infrastructure
The journey will start with a briefing and debate about the potential of closing urban water and nutrient cycles through the application of nature-based solutions (NBS). In a further step the participants will identify challenges, opportunities/driving forces and solutions for the increased integration of NBS in our urban environment in the frame of an interactive “speed boat activity”. Finally, an action-plan for future endeavours will be developed, including recommendations on necessary project proposals, research activities, policy, funding schemes, and how to strengthen collaboration with stakeholders, all in order to get our cities shipshape and resilient for future challenges.

WS8 | Application of constructed wetlands on a farm level - project WATERAGRI
The goal of this session is to present and discuss possible applications of the constructed wetland technology on agricultural farms, one of the main focuses on the H2020 project WATERAGRI. This nature-based solution, also combined with other green and sustainable technologies, can be used both for water retention (water storage and recharge of groundwater bodies) and nutrient removal (decreasing agricultural pollution but also enabling nutrient recovery), both aspects being important for agricultural areas in whole Europe. Different solutions proposed by WATERAGRI and their recent developments will be presented and discussed taking into account their benefits and suitability.
