Belgaum Alumina Refinery
Our team will reach out to you in some time
In the Alumina refinery plant at Belgaum, part of red mud (bauxite residue) generated from the plant is sent to cement industries for utilization and remaining is stored in red mud ponds. The red mud pond at Belgaum plant is quite large, lined with impervious clay to prevent leakage. The Project Authorities are making a lot of effort in forestation of the red mud ponds by planting special type and trees and grass.
The pond was designed for wet ponding. However, with time it is now being used for the dry mud stacking. An embankment is built around the red mud pond. The embankment is quite huge and old; thus required slope stabilization. The red mud pond area required monitoring for slope stabilization of embankment as well for the groundwater in the vicinity.
The real-time safety monitoring of red mud pond as well as the embankment involved instrumentation to provide immediate warning for slope stability and ground water pressures. Encardio Rite was awarded the sub-contract for monitoring works of the project. Scope of works included:
Instrument used included
All the instruments were installed successfully and are giving reliable data at pre-set frequency. Monitored data is available online through Encardio Rite’s in-house developed DRISHTI, a web based data management system (as of 2021). The monitored data is available in near real time to the stakeholders on their laptops and mobile phones.
