CNAE Brazil 3701-1/00—Wastewater network management
Subclass · Classificação Nacional de Atividades Econômicas (2.3 (2025))
Where 3701-1/00 sits
What 3701-1/00 includes
- The collection and transport of domestic or industrial sewage and rainwater through collector networks, tanks and other means of transport (e.g., sewage trucks)
- The management of domestic or industrial sewage and rainwater networks
- The operation of wastewater treatment plants (WWTPs)
- The treatment of wastewater through physical, chemical and biological processes, such as: dilution, screening, filtration, sedimentation, etc
- The treatment of industrial wastewater for pollution prevention
What 3701-1/00 excludes
- The collection, treatment and distribution of water (3600-6/01)
- The decontamination and cleaning of surface waters- due to accidental contamination, for example- by the collection of pollutants or the application of chemicals (3900-5/00)
- The construction, maintenance and repair of sewage systems (4222-7/01)
- Note: By convention, units that jointly operate water intake, treatment and distribution, and sewage collection and treatment are classified under subclass 3600-6/01.
