Treatment of waste water or sewer by means of physical, chemical or biological processes
NIC 370004 is the final six-digit endpoint for Treatment of waste water or sewer water by means of physical, chemical or biological processes. It should be selected only when the enterprise's primary business activity matches this title more closely than 370001 Operation and maintenance of sewer and drains, 370002 Operation and maintenance of other sewer systems (including sewer rodding, emptying and cleaning of cesspools, septic tanks, sinks, and pits from sewage, servicing of chemical toilets), 370003 Collecting and transporting of sewage water.
Choose 370004 only when operations, invoices and revenue narrative align with Treatment of waste water or sewer water by means of physical, chemical or biological processes. If the activity also includes 370001 Operation and maintenance of sewer and drains, 370002 Operation and maintenance of other sewer systems (including sewer rodding, emptying and cleaning of cesspools, septic tanks, sinks, and pits from sewage, servicing of chemical toilets), 370003 Collecting and transporting of sewage water, compare those pages before filing.
Use this code only when treatment of waste water or sewer water by means of physical, chemical or biological processes is the closest description of the actual business activity. If revenue comes from trading, processing, support services or a different output, compare the relevant sibling or downstream Division.
Avoid this code if the business merely supplies, transports, sells or supports this activity without performing the core business activity. In that case, choose the trade, transport, service or manufacturing code that describes what the business actually does.
Check the parent hierarchy, compare 370001 Operation and maintenance of sewer and drains, 370002 Operation and maintenance of other sewer systems (including sewer rodding, emptying and cleaning of cesspools, septic tanks, sinks, and pits from sewage, servicing of chemical toilets), 370003 Collecting and transporting of sewage water, and confirm that the official title matches the main revenue activity. For regulated or filing-critical decisions, verify the source row in the MoSPI dataset.
A wrong code can cause mismatched business descriptions, follow-up questions or later compliance cleanup. It is better to compare nearby codes before filing than to correct a weak classification later.
Use the legacy converter only as a migration aid. Old NIC 2008 matches can suggest where to look, but NIC 2025 should remain the primary reference for new code selection.
NIC 370004 should be selected only when the official title matches the main revenue-generating activity. If the business also trades, transports, processes, installs or supports the same product or service, compare nearby NIC pages before filing. This reduces the risk of choosing a code that describes the product being handled rather than the activity your enterprise actually performs.
