Borewell Intelligence
EvaraDeep
The patented borewell brain
Live borewell water level, runtime and dry-run protection — with no electronics inside the well.
The problem
Why this exists.
Farmers and rural communities depend on borewells but nobody knows how much water is left. Pumps run blindly, wells run dry mid-irrigation and damage motors, and overnight recharge goes unnoticed. Sensors dropped into the water corrode and are expensive to replace.
The principle
How it actually works.
Lower
A DC motor with an encoder pays out a string carrying a floating bob down the casing.
Detect
The instant the bob reaches the water it floats, the string goes slack, and a tension switch registers the release.
Measure
The encoder reports the exact length of string paid out — that length is the depth to water.
Retract
The motor reels the bob back up, leaving nothing submerged between readings.
Report
The depth is pushed to EvaraOne, building a live picture of drawdown and overnight recharge.

How it works
EvaraDeep measures groundwater depth by sensing the tension in a string holding a floating bob. A motor lowers the bob until it reaches the surface; the string goes slack, a tension switch fires, and an encoder reports exactly how much string was paid out. Only string and bob ever enter the well.
