Janisch & Schulz Mexico has completed a new constructed wetland near Ciudad Guadalupe Victoria. The project expands an existing lagoon-based treatment plant with two additional purification stages: eight vertical-flow planted filters (12,800 m²) and a series of polishing ponds (14,000 m²). This combination significantly enhances treatment efficiency and supports the ecological restoration of the area.rdert die ökologische Aufwertung des Gebiets.
Janisch & Schulz is participating in the DWA Climate Award with a constructed wetland at the “Little Franklin” nature kindergarten in Mannheim. The system naturally treats wastewater on-site, avoiding discharge into the public sewer. The purified water infiltrates locally, creating wetland habitats that enhance biodiversity and serve as green, cooling areas. This project demonstrates how nature-based wastewater treatment can support climate adaptation in urban environments. The award winners will be announced at the DWA “Water Days” in Berlin in September.
At J&S Engineers, we know how to purify wastewater and we have successfully been doing that for more than 30 years now. Starting off with small and medium-scale solutions, today we lead international projects for large-scale systems, treating wastewater for up to 25.000 people. Our design know-how includes complete multi-stage treatment plants, applying nature-based solutions as the core technology.
J&S Engineers lead the construction of another project, benefiting more than 20.000 people in Rayón.
Since the German Janisch & Schulz Engineering Company was awarded the contract for building several Constructed Wetland projects in Mexico in 2018, significant progress has beed made.
Our team has completed the installation of a new hybrid Constructed Wetland (CW) in a rose nursery in Steinfurth, Germany. This project, finished in June 2023, represents a significant advancement in CW innovation, achieving superior treatment efficiency with a nearly 40% reduction in space requirements!
In Paraguay’s legislative landscape, our engineers at Janisch & Schulz proudly contributed to a UN-funded infrastructure project, focusing on wastewater treatment solutions that seamlessly blend with intelligent architecture.
Innovation needs pioneers who courageously forge ahead and explore new horizons. This is exactly what happened in the early 1990s in Münzenberg, when two young engineers set out to introduce a little-known technology that was environmentally friendly, energy-saving, process-stable, and required minimal technical components: we are talking about constructed wetlands (CWs).
