Namami Gange Programme | Uttarakhand, Bihar & Jharkhand | 39 STPs | 78 OCEMS Sets | 5-Year O&M

The Project
Aaxis Nano Technologies completed the supply, installation and commissioning of Online Continuous Effluent Monitoring Systems (OCEMS) across 39 Sewage Treatment Plants (STPs) spanning Uttarakhand, Bihar and Jharkhand in the Ganga River Basin under the Namami Gange Programme. Completed in 2025, the project connects distributed effluent monitoring with Ganga Plus, a centralized monitoring platform for real-time data visibility, analytics, alerts and reporting.
Distributed Effluent Monitoring Across 39 STPs
The deployment comprises 78 OCEMS sets across 39 STPs, with two monitoring sets installed at each plant—one at the inlet to monitor influent and one at the outlet to monitor treated effluent.
The monitoring architecture combines analytical and sensor-based systems with local data acquisition andautomatic cleaning provisions to support continuous field operation.
Continuous Measurement of Critical Parameters
The OCEMS network continuously monitors key effluent-quality parameters including Flow, pH, BOD, COD and TSS across the connected STPs. At the 30 Category-I STPs, TN (eq) is additionally monitored, while the 9 Category-II STPs monitor Flow, pH, BOD, COD and TSS.
Ganga Plus: From Field Data to Centralized Intelligence
At the centre of the monitoring architecture is Ganga Plus, the Central Monitoring Station and dashboard
developed for centralized real-time monitoring and analytics. The platform brings data from distributed STP installations into a common digital environment, enabling:
- Real-time site visibility and geographic visualization
- Parameter-level monitoring
- Alerts and alarms
- Data validation and annotations
- Customized reporting
- Time-series data management
- Remote configuration
- Data transfer to CPCB/SPCB systems
Built on an IoT-based architecture with secure digital communication and API-based data exchange, Ganga Plus provides a scalable foundation for connected STP monitoring and centralized environmental data management
Built for Long-Term Monitoring
The project includes five years of comprehensive operation and maintenance, supporting continued operation of the OCEMS installations and centralized monitoring infrastructure. The long-term service scope supports system performance, data availability and continuity of monitoring across the connected STP network.
The Outcome
The 39-STP OCEMS network and Ganga Plus CMS establish a connected digital monitoring framework that brings field-level effluent data into a centralized environment. This strengthens visibility, data-driven oversight and regulatory monitoring across the connected STP network.
