Across the Himalayan terrain of Sikkim, the Central Water Commission’s specialised monitoring network brings snow-hydrological and meteorological observations into a connected data framework, with Aaxis Nano Technologies enabling the field instrumentation, satellite communication and site infrastructure behind the system.

The project connects nine strategic stations across remote and snow-sensitive locations. Designed for difficult mountain conditions, the deployment supports a shift from isolated field readings to structured datasets for flood forecasting, snowmelt runoff assessment, operational review and long-term water-resource planning.

The installed scope includes snow-depth sensors, precipitation gauges, snow density and snow water equivalent measurement, rainfall monitoring at selected sites, temperature and humidity probes, wind instruments, sunshine sensors, evaporation gauges and solar-radiation measurement. These are supported by data collection units, loggers, satellite antennas, solar power assemblies, battery backup, surge protection, masts, civil foundations and protected station infrastructure.

For dependable transmission from remote Himalayan sites, the solution uses INSAT/V-SAT-based satellite communication. Field observations are routed to CWC’s Earth Receiving Station at Delhi and further connected with the Modelling Centre at Gangtok and the FFM Directorate, CWC, New Delhi, helping technical teams access mountain data in a usable format.

Backed by a two-year comprehensive warranty and eight years of maintenance support, the installation demonstrates Aaxis Nano’s ability to deliver resilient monitoring systems for complex geographies. By combining precision instruments, communication architecture and lifecycle service, the project strengthens the technical foundation for snow-fed hydrology, forecasting preparedness and long-term water-resource planning.
