Borewell or Open Well for Ground Water Exploitation

1. What is this item?

This is your primary source of groundwater extraction.

• A borewell is a narrow, deep vertical shaft drilled using rigs (100–600 ft deep or more), usually fitted with submersible pumps.

• An open well is wider and shallower (20–50 ft deep), with masonry or stone lining—often used in areas with high water tables.

They are not interchangeable—borewells = deep groundwater, open wells = shallow aquifers or water pockets.

2. How is the Quantity Estimated?

• Usually one per 5–10 acres, depending on water table and crop type

• You also estimate based on water requirement per hectare, well yield (litres/hour), and recharge potential

• Open wells may be fewer but wider; borewells can be more in arid/dry zones

3. What are the Cost Components?

• Surveying Charges (₹3,000–₹15,000) for geophysical water prospecting

• Drilling Charges:

o ₹80–₹200 per ft depending on soil/rock type and depth

o Casing pipe (PVC/GI) cost: ₹100–₹300 per ft

• Pump installation: ₹20,000–₹60,000 depending on HP

• Electrical connection (if grid available) or solar pump setup (₹1–1.5 lakh)

• Water tank + basic platform (₹20,000–₹50,000)

• Open wells require excavation, masonry/lining, and pulley systems or submersible pumps

4. Going Rates & How Unit Cost is Calculated

• Typical Borewell (up to 300 ft depth):

👉 ₹1.5 lakh to ₹2.5 lakh including pump and pipe

• Deep Borewell (400–600 ft):

👉 ₹2.5 lakh to ₹4 lakh

• Open well with masonry:

👉 ₹1.2 lakh to ₹2 lakh depending on diameter, soil & water yield

• Solarized versions add another ₹1–1.5 lakh for sustainability and grid-independence

💡 Pro Tip: Always consider rainwater recharge pit integration nearby to prolong borewell life. For open wells, protective fencing and periodic desilting are crucial.
