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.

The J&S Wetland Roofs system represents a significant advancement in the purification of wastewater on green roofs, simultaneously offering passive cooling effects in buildings.

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.
