NIC 422006 is the final six-digit endpoint for Construction and maintenance of water main and line connection, water reservoirs including irrigation system (canal). It should be selected only when the enterprise's primary construction activity matches this title more closely than 422001 Construction of thermal and nuclear power plants, 422002 Construction of hydropower plants and Pumped Storage Projects, 422003 Construction, erection, and maintenance of power transmission and distribution lines, including radar infrastructure for grid monitoring, load balancing, fault detection, and overhead lines or conductor rails for railways..
Choose 422006 only when operations, invoices and revenue narrative align with Construction and maintenance of water main and line connection, water reservoirs including irrigation system (canal). If the activity also includes 422001 Construction of thermal and nuclear power plants, 422002 Construction of hydropower plants and Pumped Storage Projects, 422003 Construction, erection, and maintenance of power transmission and distribution lines, including radar infrastructure for grid monitoring, load balancing, fault detection, and overhead lines or conductor rails for railways., compare those pages before filing.
Use building or civil engineering codes for whole-project construction. Use specialized construction codes when the firm mainly performs electrical, plumbing, HVAC, demolition, roofing, finishing or similar trade work.
Use the code that reflects the contractor's own contracted responsibility. A project developer, civil contractor and specialist installer can fall under different NIC codes even on the same site.
Check the parent hierarchy, compare 422001 Construction of thermal and nuclear power plants, 422002 Construction of hydropower plants and Pumped Storage Projects, 422003 Construction, erection, and maintenance of power transmission and distribution lines, including radar infrastructure for grid monitoring, load balancing, fault detection, and overhead lines or conductor rails for railways., 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 422006 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.
