Workshop on Nature-Based Solutions for Water Sanitation (MULTISOURCE project)

From June 5th to June 9th, 2023, an influential workshop on wastewater treatment with natural solutions, within the framework of the European project "MULTISOURCE," was held in Germany. The MULTISOURCE project comprises 20 members from 9 European countries, including France, Spain, Belgium, Norway, Italy, Germany, Slovenia, Austria, Denmark, and three other countries: the US, Brazil, and Vietnam. This workshop marked a significant step forward in addressing water sanitation challenges using Nature-Based Solutions (NBS) and was attended by experts, researchers, and stakeholders passionate about sustainable water treatment.

Nature-Based Solutions for Water Sanitation

Nature-based solutions for water sanitation are innovative, engineered systems that mimic and utilize natural environments to treat wastewater. These solutions rely minimally on mechanical elements and instead leverage plants, soil, bacteria, and other natural processes to remove pollutants from wastewater. By embracing NBS, the use of chemicals is reduced, energy consumption is minimized, and water is treated sustainably, cost-effectively, and with a low environmental impact. NBS systems also boast an extended performance life, making them a promising avenue for wastewater treatment.

MULTISOURCE Project Objectives

The overarching goal of the MULTISOURCE project is to collaborate with local, national, and international stakeholders to demonstrate Enhanced Natural Treatment Solutions (ENTS) for a broad spectrum of urban waters. This initiative aims to develop innovative tools, methods, and business models that facilitate citywide planning and the long-term operation and maintenance of NBS for water treatment, storage, and reuse in urban areas across the globe.

HCMUT's Role in the MULTISOURCE Project

Ho Chi Minh City University of Technology (HCMUT), as a proud member of this ambitious project, plays a crucial role primarily in work packages No. 3 and No. 6. Their role involves adapting water treatment models developed and tested by more advanced nations to the context of Ho Chi Minh City. They are actively engaging with relevant parties, such as companies, consultants, and researchers, to advocate for the implementation of NBSWT in the city.

Project Pilots and Collaborators

The MULTISOURCE project includes seven pilot projects treating various urban waters. These pilots are located in two individual municipalities (Girona, Spain; Oslo, Norway), two metropolitan municipalities (Lyon, France; Milan, Italy), and international partners in Brazil, Vietnam, and the USA. Each of these locations contributes to key project activities, such as ENTS pilots, risk assessment, business model development, technology selection, and the creation of the MULTISOURCE Planning Platform.

Innovative Tools and Planning Platform

The MULTISOURCE project aims to deliver new insights into ENTS and their effectiveness in removing waterborne contaminants, reducing chemical and biological hazards, and enhancing urban habitats. A critical aspect of the project is the development of the MULTISOURCE Planning Platform, which utilizes urban archetypes to identify regions suitable for NBSWT application. This platform empowers stakeholders to conduct large-scale planning, fostering circularity and sustainable development in the urban water sector. It also addresses barriers to the widespread adoption of nature-based solutions for water treatment.

The Workshop on Wastewater Treatment with Nature-Based Solutions within the MULTISOURCE project is a testament to international collaboration and the commitment to sustainable water management. As the world faces growing water scarcity and pollution challenges, the use of NBS for water sanitation emerges as a beacon of hope. By harnessing the power of nature, minimizing environmental impact, and promoting circularity, the MULTISOURCE project and its dedicated members, including HCMUT, are pioneering a path towards a more sustainable and resilient urban water future.
