IRIDRA S.r.l., founded in 1998, is a private consulting engineering firm composed by an interdisciplinary group of professionals (an environmental engineer, an environmental chemist, a mechanical engineer, two biologists). All IRIDRA's members have a multi-annual experience (since 1992) in water management and an excellence expertise in wastewaters treatment with natural systems (Constructed Wetlands, CWs).

IRIDRA realises any activity connected with analysis, planning and design for sustainable water management and sanitation. It was the first engineering company in Italy specialised on the design of CWs for wastewater treatment and designed and managed over 250 systems to face several wastewater problems in different geographical situations. It is also leading the sustainable sanitation and Ecosan concept in Italy, designing the water cycle of some innovative buildings in Italy. To preserve its leadership, keeping to date with the latest technical and scientific advances, IRIDRA took part in several research, demonstration and dissemination projects (such as Swamp, Zer0-M, Life Sellustra, Life WATACLIC, ENPI SWMED), the results of which are often presented to the most important scientific conventions and are published on international peer reviewed journals. Since 1999, the Technical Director of IRIDRA is the Italian referent for the International Water Association Specialist group on the use of Macrophytes for Water Pollution Control.

In Italy IRIDRA is the leader company in natural treatment design: during the past years Iridra has designed most of the more relevant constructed wetland systems currently in operation in Italy.
