Borewell Drilling | 10 HP Motor 90 Feet Deep Coconut water checking method |Boring Machine Borewells

Welcome to our channel! Watch the complete borewell drilling process in this video, where we go 90 feet deep to access groundwater. We used a powerful 10 HP submersible motor (three-phase) and a professional boring machine (drilling rig) for efficient and precise results.
This video also features the fascinating, age-old coconut water checking method (dowsing) used by a local water diviner to pinpoint the ideal drilling location.
========================
Video Highlights:
Borewell Drilling: See the step-by-step process of drilling a borewell.
Depth Achieved: Drilling up to 90 feet to find sufficient water for domestic/agricultural use.
Equipment: Overview of the boring machine and the powerful 10 HP motor installation.
Water Detection: Watch the traditional coconut method in action and see the water come out!.
========================
Technical Specifications (Typical for this setup):
Motor Power: 10 HP (Horsepower)
Motor Phase: Three Phase (common for higher HP borewell pumps)
Drilling Depth: 90 Feet
Pump Head Range: Typically 51-90 meters (approx. 167-295 feet), suitable for this depth.
Machine Type: Gear model or DTH (Down The Hole) drilling machine.
========================
Disclaimer on Water Location Methods:
The coconut water checking method is a traditional practice and is not scientifically proven. The movement of the coconut is attributed to the ideomotor effect, an unconscious muscular action. For reliable groundwater detection, a professional hydro-geological survey using scientific methods like electrical resistivity is recommended.

Common Drilling Technologies (Khanan Methods)
Depending on your soil type and the 90-foot depth mentioned earlier, different machines are used:

Borewell drilling (often called Khanan in Hindi) is the process of drilling a narrow shaft into the earth to access underground aquifers. For a 90-foot deep project using a 10 HP motor, here is a comprehensive breakdown of methods, equipment, and traditional practices.
1. Water Detection: Traditional vs. Scientific
Coconut Water Method (Dowsing): A traditional, non-scientific practice where a person holds a coconut while walking; it is believed the coconut will turn vertical when over a water stream. While popular in rural India, scientists attribute its movement to the ideomotor effect (unconscious muscle movements).
Scientific Methods: Professional Electrical Resistivity Surveys measure ground resistance to map water-bearing layers (aquifers) accurately.
2. Drilling Machines (Khanan Equipment)
DTH (Down-The-Hole) Rig: The most common for rocky terrain. It uses high-pressure air to power a hammer at the bottom of the hole, breaking rock at speeds of 1,500–2,500 strikes per minute.
Rotary Drilling: Uses a rotating bit to crush soil and rock; highly efficient for soft to medium-hard formations.
Auger Machines: Best suited for soft soil at shallow depths (up to 150 feet), making them ideal for a 90-foot project.
Robo Borewells: Specialized compact rigs that can drill in tight spaces with as little as a 6-foot gap.
3. Motor & Pump Specifications (10 HP Setup)
A 10 HP submersible motor is powerful for a 90-foot depth and is often used when high water volume is required for agriculture or large buildings.
Power: Usually 3-Phase to handle heavy loads.
Head Range: A 10 HP pump like the Kirloskar KS6 Series can handle depths (head) far exceeding 90 feet, often up to 200+ feet.
Durability: Modern motors feature CED coating for 5x more corrosion resistance and "Sand Fighter" designs to prevent internal damage in sandy wells.
4. Estimated Costs for 2025
Component Estimated Price (INR)
Drilling (up to 150 ft) ₹50 – ₹100 per foot
Casing (PVC) ₹300 – ₹500 per foot
10 HP Submersible Pump ₹50,000 – ₹82,000
Geological Survey ₹5,000 – ₹10,000

DTH (Down-The-Hole) Drilling: Most common for rocky terrain. It uses a pneumatic hammer to break hard rock and air pressure to clear debris.
Rotary Drilling: Ideal for very deep wells (up to 3,000 feet) and diverse soil conditions.
Auger Method: A helical screw method used for soft soil and shallower depths, typically up to 100–150 feet.
Cost Estimates for 2026
250-Foot Borewell: Drilling a standard 6.5-inch borewell typically costs between ₹48,000 and ₹55,000, including casing pipes and labour.
300-Foot Borewell: For a deeper setup with pump installation, costs generally range from ₹80,000 to ₹1,50,000.
