Sewerage
What this code covers
Use this class for sewerage when the main activity includes Operation of wastewater treatment facilities for reuse (e.g. of agricultural, industrial and road cleaning wastewater or collected rainwater), or for artificial recharge or augmentation of groundwater bodies and Collection and transport of wastewater from users (e.g. households or industrial units). Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
No child codes; this is a class-level code.
- operation of wastewater treatment facilities for reuse (e.g. of agricultural, industrial and road cleaning wastewater or collected rainwater), or for artificial recharge or augmentation of groundwater bodies
- collection and transport of wastewater from users (e.g. households or industrial units)
- collection and transport of rainwater by means of sewerage networks, collectors, tanks and other means of transport (e.g. sewage vehicles, etc.)
- maintenance and cleaning of sewers and drains, including sewer rodding
- further treatment of sludge extracted from wastewater, see division 38
- anaerobic digestion, see 38.2
- aerobic treatment, such as composting, see 38.21
- incineration with energy recovery, see 38.22
- Compare with 38, 38.2, 38.21 when the main activity overlaps another code.
- Check national equivalent caveats before using this code for local registration or filing workflows.
- If the main revenue activity appears in an exclusion, compare the alternative code before deciding.

What is NACE 37.00 used for?
Use NACE 37.00 for sewerage when the main activity matches this scope: Use this class for sewerage when the main activity includes Operation of wastewater treatment facilities for reuse (e.g. of agricultural, industrial and road cleaning wastewater or collected rainwater), or for artificial recharge or augmentation of groundwater bodies and Collection and transport of wastewater from users (e.g. households or industrial units). Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 37.00?
Typical examples include Operation of wastewater treatment facilities for reuse (e.g. of agricultural, industrial and road cleaning wastewater or collected rainwater), or for artificial recharge or augmentation of groundwater bodies, Collection and transport of wastewater from users (e.g. households or industrial units), and Collection and transport of rainwater by means of sewerage networks, collectors, tanks and other means of transport (e.g. sewage vehicles, etc.).
When might 37.00 not be the right code?
Review another code when the activity is closer to further treatment of sludge extracted from wastewater, see division 38 and anaerobic digestion, see 38.2.
Which codes should I compare before choosing 37.00?
Compare 37.00 with 38 Waste collection, recovery and disposal activities, 38.2 Waste recovery, and 38.21 Materials recovery when the activity description is ambiguous.
Use this division for waste collection, recovery and disposal activities when the main activity includes Local hauling of waste materials and the operation of materials recovery facilities, i.e. facilities that transform waste, including scrap, whether sorted or not, into secondary raw materials and Activities of units implementing producer responsibility obligations for the management of waste on behalf of the original waste producers. These organisations usually bear the responsibility for the treatment of waste, delegated to them from the original producers of products or packaging.. Check exclusions and nearby codes before applying it to a mixed activity.
Use this group for waste recovery when the main activity includes Materials recovery and Energy recovery. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for materials recovery when the main activity includes Further included is the recovery of materials from waste streams in the form of: (1) separating and sorting recoverable materials from non-hazardous waste streams; or (2) separating and sorting of commingled recoverable materials (for example, paper, plastics, used beverage cans and metals) into distinct categories. and Examples of the mechanical or chemical transformation processes that are undertaken include:. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for energy recovery when the main activity includes Energy recovery. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for incineration without energy recovery when the main activity includes Incineration without energy recovery. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for remediation activities and other waste management service activities when the main activity includes Decontamination of soils and groundwater at the place of pollution, either in situ or ex situ, using, e.g. mechanical, chemical or biological methods and Decontamination of industrial plants or sites, including nuclear plants and sites. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for construction of utility projects for fluids when the main activity includes Construction of civil engineering structures for: and Long-distance, underwater and urban pipelines. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for plumbing, heat and air-conditioning installation when the main activity includes Installation, maintenance and repair of: and Heating systems (e.g. heat pumps, solar thermal collectors). Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for rental and leasing of other machinery, equipment and tangible goods n.e.c. when the main activity includes Rental and operating leasing, without an operator, of other machinery and equipment generally used as capital goods by industries: and Engines and turbines. Check exclusions and nearby codes before applying it to a mixed activity.
Use this group for the broader activity area of sewerage, including Sewerage. Open the child codes when a more specific code is needed.
Rev. 2 code 37.00 maps to the same Rev. 2.1 class 37.00 Sewerage.
Official close match imported from NACE Rev. 2.1.
Low operational impact is expected, but systems should still store the target Rev. 2.1 version explicitly.
Confirm the target version field and update references where Rev. 2.1 is required.
