CAEN Division 37: Collection and Treatment of Wastewater
CAEN Division 37, entitled "Collection and Treatment of Wastewater", represents an essential component of the environmental infrastructure in Romania. It covers the entire wastewater management chain, from collection from households and factories to treatment for the protection of water resources. In the context of accession to the European Union, Romania had to align treatment standards with European directives, which generated massive investments in the modernization of treatment plants and the expansion of sewerage networks. Macroeconomically, this niche contributes to public health and environmental sustainability by reducing pollution of surface and groundwater. Entrepreneurs active in the field face challenges related to high operating costs, the need for qualified personnel, and compliance with increasingly strict environmental regulations. However, the demand for collection and treatment services is increasing, especially in urban and industrial areas, where wastewater volumes are significant. The long-term outlook remains favorable, with financial support from European and national funds for infrastructure development. To succeed, operators must focus on energy efficiency, technological innovations, and partnerships with local authorities.
