Patna: The illegal trade in the red sand of Bihar’s Son River continues to remain a major challenge despite several measures introduced by the state government to control unauthorised mining and transportation.
CCTV cameras, drone surveillance, e-challans, transit passes and vehicle inspections form part of the monitoring system. Yet, illegal mining and transportation have not been completely eliminated.
The key question is why illegal operators continue to find room to operate despite these technological and administrative measures.
One of the biggest challenges lies in the gap between the resources available to enforcement agencies and the scale of the organised sand trade. While operators may have access to multiple vehicles, boats and other resources, the manpower available for surveillance and enforcement remains limited.
Monitoring 177 Ghats, But Resources Remain Limited
The mining department’s surveillance mechanism is largely focused on sand ghats, where CCTV cameras and drones are being used to monitor mining and loading activities. Authorities also undertake vehicle inspections, e-challans and seizures when illegal sand transportation is detected.
However, the sand supply chain does not end at the ghat.
After extraction, sand can move through secondary loading points, temporary storage locations and stockyards before reaching the market. Monitoring only the riverbank therefore makes it difficult to track the entire movement of sand.
Limited manpower further adds to the challenge. Deploying personnel across a large number of ghats leaves fewer resources available to monitor secondary stock points and remote areas where illegal activity may shift.
Illegal Networks Can Change Routes After Crackdowns
Another challenge is that enforcement action at one location may not necessarily dismantle the entire network.
When surveillance is intensified at a particular ghat or loading point, illegal operators may shift their activities to another location. Sand movement across districts can involve boats on the river as well as trucks and tractors on roads, making coordination between districts crucial.
A crackdown in one district is therefore likely to have a wider impact only when neighbouring districts simultaneously share intelligence and act against suspicious movements.
Arwal Investigation Reveals Stock Discrepancy
One of the most important aspects of monitoring the sand trade is determining where extracted sand eventually goes.
During an audit of sand quantities, an investigation linked to Arwal district in August reportedly found a discrepancy between the quantity recorded as having been extracted from ghats and the quantity of sand subsequently found in stock.
According to the available information, the estimated value of the additional illegal stock was around Rs 1.63 crore.
The case highlights a major weakness in supply-chain monitoring. Recording sand at the point of extraction is not enough. Authorities also need to establish where the material went, which stock point received it, which vehicle transported it and how the transaction was conducted.
CCTV and Drone Surveillance Need Continuous Monitoring
CCTV cameras are an important component of surveillance at sand ghats. They can help establish when and where mining or loading activities took place.
However, the effectiveness of the system depends on cameras remaining operational and being monitored regularly. Records showing how long cameras remained non-functional and how quickly technical problems were addressed are equally important.
Drones can provide surveillance in locations that are difficult for ground teams to reach, including isolated river stretches, remote ghats and concealed loading points.
But drone surveillance can only be effective if information gathered through aerial monitoring is followed by timely enforcement action and properly documented.
Off-Season Poses Additional Enforcement Challenge
The period when legal sand mining remains suspended is considered particularly sensitive from an enforcement perspective.
The July 15 to October 15 period is an off-season for legal sand mining, increasing the importance of regular surveillance of river stretches and ghats.
During this period, authorities need to ensure that CCTV systems remain operational and drone patrols are maintained. With legal mining activity suspended, unusual movement of boats, vehicles or machinery around sand ghats can warrant closer scrutiny.
Catching Trucks Alone May Not Break the Network
Enforcement operations against illegal sand mining often result in the seizure of trucks, tractors, heavy vehicles or boats carrying unauthorised sand.
While such action can disrupt illegal transportation temporarily, it may not dismantle the larger network if the people coordinating the operation remain active.
Effective enforcement therefore needs to go beyond the driver or boat operator. Investigations may need to examine the roles of ghat operators, stockists, transporters, buyers and other participants in the supply chain.
Digital Tracking Could Help Plug the Gaps
A long-term solution may lie not only in increasing manpower but also in digitally tracking the entire sand supply chain—from the ghat to the final market.
Every legally extracted consignment could be assigned a digital record, while secondary stock points could be geo-tagged and subjected to regular physical verification.
The quantity recorded at stock points could then be matched with e-challan and transit-pass records. Authorities could also analyse vehicle registration numbers, ownership details, repeated movements and activity across multiple districts to identify suspicious patterns.
Such an integrated system could help authorities detect discrepancies before illegal sand reaches the market.
Real-Time Coordination Needed Across Districts
Illegal sand transportation does not necessarily follow district boundaries, making inter-district coordination essential.
Areas connected to the Son River, including Patna, Bhojpur and Arwal, could benefit from stronger real-time information-sharing mechanisms. If suspicious activity is detected at one ghat, neighbouring districts could be alerted immediately.
Information on boats, trucks, tractors and stock points could be shared between the police, administration and mining department, allowing joint teams to respond quickly when required.
The Challenge Extends Beyond the River Ghats
The illegal Son sand trade is not simply a problem confined to river ghats. It involves a wider chain extending from extraction and loading to storage, transportation and sale.
That means surveillance also needs to cover the entire supply chain.
Until authorities can maintain a reliable account of every legal sand consignment from ghat to market, regularly verify stock points and ensure real-time coordination between districts, CCTV cameras, drones and e-challans alone may not be enough to completely eliminate illegal sand mining.
