When an agricultural borewell stops pumping water mid season, most farmers panic thinking the motor burned out. More often than not, the fault lies in a corroded underground joint or a ruptured cable deep down the casing pipe. Setting up a dedicated cable testing and jointing unit solves an immediate headache across nearby villages. You pack a reliable insulation tester, cable tracer, resin jointing kits, and heat shrink sleeves into a sturdy tool chest.
When a distress call comes from a farm or warehouse, you reach the spot, test the line resistance, locate the exact puncture, and cast a water tight seal. Word spreads like wildfire among local pump repair shops who hate handling cable issues themselves. It keeps you on the road throughout planting season, earning upfront cash from relieved growers.

Hundreds of agricultural pump connections face joint failure every season due to low quality electrical tape wraps submerged under deep water columns. Providing certified waterproof resin jointing alongside resistance diagnostics guarantees continuous irrigation for cultivators who cannot wait days for urban technicians.
Farmers with submersible pumps in borewells, and small commercial users like brick kilns, poultry farms and nurseries that depend on buried power cables. When a cable joint fails under water or a buried cable faults, most of them call the village wireman, who wraps the joint in tape or pulls the whole cable up to guess where the fault is. The farmer decides to pay when the pump trips again and again in the middle of the sowing or irrigation season, and a crop is at risk.
With 30 million groundwater pumps in India, according to Climate Scorecard in February 2025, the number of joints and cables in the ground is huge. Farmers who have lost a crop to repeated pump failures are the easiest to convince.
Charge per call for fault finding, and per joint for making watertight resin or heat shrink joints, with materials billed separately. Inka Enterprise in Ahmedabad lists an epoxy type straight through joint for 1.1 kV cable at ₹450 a piece and a heat shrink straight joint at ₹250. Your labour, testing and the promise that the joint will hold under water make up the rest of the price. Pulling and reinstalling the pump is a separate, higher charge. Farmers who trust you call again every season and recommend you to neighbours.
Village wiremen often make taped joints that let water in and fail again within weeks. Many cannot locate buried faults without digging up long stretches of cable. Your edge is testing insulation before and after, making proper sealed joints, and finding faults quickly with the right instrument. Show the farmer the insulation reading so they see the difference. A joint that lasts the season wins loyalty.
Best suited for young wiremen with proper motor rewinding or industrial wiring practice. Unsuitable for anyone expecting a comfortable counter job away from dirt roads and sun.

You need an insulation resistance tester, a multimeter, a clamp meter, a cable fault finder for buried cables, cable cutters and strippers, a heat gun, and a stock of resin and heat shrink joint kits. Tajalli Tech, a cable fault locating firm, lists methods such as the Murray loop and time domain reflectometry, which shows the range of equipment used from simple to advanced. A small generator or inverter helps where there is no power at the pump. A motorcycle to reach fields is essential. We found no sourced total for a starting kit.
Work peaks in sowing and summer irrigation seasons, when every day of a stopped pump hurts the farmer. Each call brings a fault finding fee plus joint and material charges. We found no published income figure for a borewell cable jointing service. Growth depends on how many villages you cover and whether you add pump pulling and motor work. Long travel on rural roads limits the number of calls in a day.
No sourced cost or earnings figures exist for this idea yet, so none are shown. Nothing here is an estimate.

Learn cable jointing, insulation testing and fault finding from an experienced pump or cable technician.
Buy an insulation tester, multimeter, clamp meter, heat gun and jointing tools.
Stock resin and heat shrink joint kits for flat submersible cables in common sizes.
Add a buried cable fault finder once you have steady work.
Leave cards with pump dealers, seed shops and electrical shops in nearby villages.
Record the insulation reading before and after every job and show it to the farmer.
Offer pre-season checks of cables and joints before the main irrigation period.
Wiremen and pump mechanics who switch to this work often get their first paid call within days in the irrigation season. Starting fresh, expect two to four weeks while farmers learn your name. Leaving cards with pump dealers and seed shops speeds things up.
Tape lets water seep in over time, especially under the pressure of deep water. Once water reaches the copper, the insulation drops and the pump trips. Resin or heat shrink joints seal the conductor properly. Test insulation before lowering the pump.
Inka Enterprise lists an epoxy type straight joint for 1.1 kV cable at ₹450 and a heat shrink joint at ₹250. Your labour and testing are added on top. Explain the cost difference to farmers used to cheap tape. A joint that lasts saves them repeated calls.
Methods range from simple resistance tests to instruments that send pulses along the cable and measure the reflection. Tajalli Tech lists the Murray loop and time domain reflectometry among its methods. Start with basic tests and add equipment as work grows. Finding the fault quickly saves digging.
Yes, it peaks during sowing and summer irrigation when pumps run long hours. Monsoon can be slower. Pre-season checks and motor work help fill quieter months.
