Tadoba tiger reserve deploys sensor system to automate wildlife waterholes

Tadoba-Andhari Tiger Reserve in Maharashtra has deployed an automated sensor-based system to manage water levels across its wildlife waterholes, marking a major technological advancement in forest water management.

The pilot initiative, introduced in the Chandrapur district sanctuary, automatically controls solar-powered pumps supplying artificial waterholes. By turning pumps on when water drops below a set threshold and shutting them off once full, the system prevents excess groundwater extraction and eliminates water waste.

Forest officials designed the setup to solve a long-standing operational challenge in tiger conservation zones. While solar pumps keep waterholes filled during extreme heat, they previously operated continuously throughout daylight hours. This frequently caused pools to spill over, wasting scarce groundwater and requiring field staff to manually turn off pumps in remote tiger habitats.

"The device automatically starts and stops pumps based on water levels," said Dr Prabhu Nath Shukla, Field Director of Tadoba-Andhari Tiger Reserve. He noted that the system integrates a level sensor, controller, and relay wired directly to each pumping unit.

By automating this process, forest managers reduce the need for physical inspections, protecting forest guards from dangerous wildlife encounters while keeping water sources consistently full.

Waterhole infrastructure across the reserve

Tadoba-Andhari relies on a combination of natural streams and artificial water points to sustain its dense population of tigers, leopards, and herbivores. During recent summer heatwaves, proactive management ensured that no external water tankers were required to maintain the reserve's supply.

Grid mapping for equitable water distribution

To ensure wildlife across all parts of the sanctuary has equal access to drinking water, reserve management is dividing the core forest area into systematically planned geographical grids. Each grid will be equipped with dedicated waterholes by the end of the year.

Officials emphasized that expanding the sensor system across these new grids will strengthen groundwater conservation and safeguard wildlife during severe drought conditions.
