In this transdisciplinary analysis the performance of a small-scale horizontal flow constructed wetland is assessed, this type of systems are called “Biojardinera” in Costa Rica. Organic matter, nutrients and microbiological water quality standards are analyzed and compared with reported efficiencies of similar treatment systems in the country. Furthermore, a multidimensional assessment for the implementation of this low-cost ecotechnology in the context of Costa Rica was carried in the SUW Real-World Laboratory, analyzing socio-economic and political-regulatory dimensions. The results contribute to the understanding of the performance and application potential needed for the scale-up of this type of Nature-based Solution for water quality improvement.
