As Bangalore continues to grow as a bustling urban hub, the need for reliable water sources has skyrocketed.
Borewell drilling remains one of the most common methods for accessing groundwater to meet residential, agricultural, and commercial water requirements.
However, borewell drilling in Bangalore comes with its own set of costs, rules, permissions, and timing considerations.
In this article, we will explore all aspects of borewell drilling in Bangalore, including cost estimates, regulations, and tips for successful drilling.
Why Borewell Drilling is Important in Bangalore
1. Groundwater Dependency
With municipal water supply systems often unable to meet demand, many households and establishments rely heavily on borewells to access groundwater.
2. Irregular Water Supply
The rapid urbanization of Bangalore has strained water resources, leading to erratic supply. Borewells provide a steady alternative, ensuring water availability even during dry seasons.
3. Long-Term Water Solution
Borewells are a one-time investment that can provide water for several years if drilled and maintained properly.
Factors to Consider Before Borewell Drilling
1. Geological Survey
Before drilling, a geophysical survey is essential to identify the best location with adequate groundwater availability. Professional services can assist in pinpointing the ideal spot.
2. Borewell Drilling Permission in Bangalore
It is mandatory to obtain permission from the Karnataka Groundwater Authority (KGWA) before drilling a borewell in Bangalore. The government enforces strict rules to regulate groundwater usage and prevent overexploitation.
- Application Process: Submit the required documents, including proof of property ownership, water usage details, and a detailed plan of the proposed borewell.
- Approval Timeline: Permissions are generally granted within a few weeks if all requirements are met.
3. Borewell Drilling Rules in Bangalore
To ensure sustainable groundwater usage, the following rules apply:
- Borewells must be located at least 250 meters away from public water sources.
- Adequate safety measures should be in place to prevent accidents during drilling.
- Borewells must be sealed if they are non-functional to prevent contamination of the aquifer.
4. Borewell Drilling Timings in Bangalore
The BBMP (Bruhat Bengaluru Mahanagara Palike) and other authorities regulate borewell drilling timings to minimize noise pollution. Drilling is typically allowed between 6:00 AM and 6:00 PM. Violations may result in penalties.
Borewell Drilling Process
Step 1: Survey and Site Selection
Geological and hydrological surveys determine the water table depth and optimal drilling location.
Step 2: Drilling
A rotary or percussion drilling rig is used to bore into the ground. The drilling depth in Bangalore generally ranges between 200 to 1,500 feet, depending on the water table.
Step 3: Casing Installation
A casing pipe is installed to prevent the borewell from collapsing and to ensure clean water flow.
Step 4: Yield Test
A test is conducted to measure the borewell’s water yield and determine its efficiency.
Step 5: Pump Installation
A submersible or jet pump is installed based on the borewell depth and water yield.
Borewell Drilling Cost in Bangalore
The borewell drilling in Bangalore cost depends on various factors, including drilling depth, geological conditions, and the type of casing material used.
Expense | Estimated Cost (₹) |
|---|---|
Drilling (per foot) | ₹80 – ₹150 |
Casing Pipe (per foot) | ₹200 – ₹400 |
Geological Survey | ₹5,000 – ₹10,000 |
Pump Installation | ₹10,000 – ₹50,000 |
Total Cost (average) | ₹50,000 – ₹2,50,000 or more |

Challenges in Borewell Drilling
1. Dry Borewells
In some cases, drilling may fail to yield water, leading to financial loss. Conducting a thorough survey minimizes this risk.
2. High Costs
Drilling deeper borewells can be expensive due to equipment costs and geological challenges.
3. Regulatory Compliance
Failure to adhere to borewell drilling rules in Bangalore may result in fines or the shutdown of operations.
Maintenance Tips for Borewells
- Regularly test water quality to ensure it is safe for consumption.
- Service the pump every 6 to 12 months to maintain efficiency.
- Keep the borewell surroundings clean to prevent contamination.
Sustainable Borewell Practices
To ensure long-term groundwater availability, adopt the following practices:
- Rainwater Harvesting: Direct rainwater into recharge pits to replenish groundwater levels.
- Water Conservation: Use water judiciously to prevent over-extraction.
- Community Initiatives: Collaborate with neighbors or local bodies to monitor and manage groundwater usage.
