Presentation and Sponsorship at the Pan-American Conference on Nature-Based Water Treatment in Paraguay 2025
In Asunción, Paraguay, the VII Pan-American Conference on Nature-Based Water Treatment using Constructed Wetlands (CW) took place from June 16 to 20, 2025—a key event for the global exchange on sustainable water technologies in Latin America. Organized by the Faculty of Exact and Natural Sciences (FACEN-UNA) and the Pan-American Network for Nature-Based Water Treatment (HUPANAM), the event brought together over 150 experts from 12 countries.
Promoting Innovative and Adapted Solutions
As a sponsor of the conference, J&S Engineers supported the technical exchange on Constructed Wetlands as a nature-based, cost-effective, and process-stable solution. Our company founder, Eng. Jörg Janisch, presented insights and projects from over 30 years of company history. His practical perspectives demonstrated how CWs excel in developing countries, purifying wastewater and enabling its reuse for irrigation. He particularly emphasized the relevance of CWs in Latin America and other developing regions, where affordable, low-maintenance, and durable wastewater solutions are urgently needed.
CW: Ideal for Developing Regions
Constructed Wetlands offer significant advantages for regions with limited resources. Their long lifespan, low susceptibility to disruptions, and minimal energy and operating costs make them ideal for use in developing countries. At the same time, they ensure stable and high purification quality, even under challenging climatic or infrastructural conditions. “CWs are not only ecologically but also economically sustainable, enabling decentralized water treatment that operates independently of expensive large-scale facilities,” explained Jörg Janisch. These characteristics position CWs as a potential game-changer for improving water and sanitation services in Latin America and beyond.
Conference Highlights
The event offered a diverse program of presentations, workshops, and excursions. Notable contributions included those from Carlos A. Arias (Aarhus University, Denmark), Joan Garcia (Spain), and Gladys Vidal (Chile), who provided new perspectives on CW design, sludge treatment, and microbiome analyses. An excursion to a pilot facility at FACEN-UNA and a reed grass cultivation site in Itá showcased the practical implementation of these technologies. The conference created a platform for sharing knowledge, strengthening networks, and advancing innovative approaches.
We thank FACEN-UNA and HUPANAM for their organization and look forward to the continued development of these forward-looking technologies.
