How to Choose the Right Submersible Pump for a Borewell in Ahmedabad
A good borewell needs the right pump to deliver water properly. Choosing a pump only by HP, price or brand can lead to low water pressure, high electricity use, frequent tripping or early pump failure.
The right Submersible Pump for Borewell should match the borewell depth, water level, daily water demand, required discharge and total delivery head.
Jaldhara Borewell provides Submersible Pump Installation in Ahmedabad for homes, farms, housing societies, commercial buildings and industrial properties. Its installation process includes borewell evaluation, pump selection, fitting, electrical checks and performance testing.
This guide explains how to choose a suitable borewell pump and which common mistakes you should avoid.
Quick Answer: How Do I Choose the Right Submersible Pump?
To choose the right submersible pump, check these seven factors first:
- Borewell depth
- Static water level
- Dynamic water level
- Required water discharge
- Total delivery head
- Pipe diameter
- Available electrical supply
Jaldhara Borewell also uses these factors when selecting and installing submersible pumps for borewell systems.
Do not choose a larger HP pump simply because you want more water. Groundwater availability depends on the borewell itself. An oversized pump cannot create more groundwater and may operate inefficiently.
What Is a Submersible Pump?
A submersible pump is an electric water pump installed inside a borewell or tubewell below the water level.
Instead of pulling water from the surface, the pump pushes groundwater upward through a delivery pipe.
A simple borewell system works like this:
Groundwater → Submersible Pump → Delivery Pipe → Storage Tank / Irrigation / Building
Because the pump operates below the water level, it is widely used for deep groundwater systems in residential, agricultural, commercial and industrial applications.
Why Correct Pump Selection Matters
A borewell and pump should work as one system.
If the pump is too small, you may face:
- Low discharge
- Slow tank filling
- Poor water pressure
- Difficulty supplying upper floors
- Longer pump running time
If the pump is too large, you may face:
- Higher power use
- Excessive pumping
- Frequent cycling
- Unnecessary stress on the system
- Higher purchase cost
Start with the Borewell Depth
The first detail to check is the total borewell depth.
For example, a pump installed in a shallow borewell may have very different requirements from one installed in a deep borewell.
But total bore depth alone is not enough.
You should also know:
- Where the water level starts
- How much the level falls while pumping
- Where the pump will be installed
Understand Static and Dynamic Water Levels
Two water-level measurements are useful when selecting a borewell pump.
Static Water Level
This is the water level inside the borewell when the pump is not running.
Dynamic Water Level
This is the water level while the pump is operating.
The dynamic level can be lower because water is being pumped out.
Jaldhara lists both static and dynamic water levels among the main factors affecting pump performance.
Why Does This Matter?
The pump should remain properly submerged during operation.
If the water level drops too far, the pump may not operate correctly.
This is especially important in:
- Summer
- Low groundwater periods
- High-demand agricultural use
- Continuous industrial use
Problem: “My Borewell Is Deep, So Should I Buy a High-HP Pump?”
Not automatically.
A deeper borewell may require a pump that can develop enough head, but HP should also be based on:
Water Level + Required Discharge + Delivery Height + Pipe Losses + Application
A correctly selected lower-HP pump may sometimes be more suitable than a larger pump that does not match the system.
Calculate Your Daily Water Requirement
Before choosing a pump, decide how much water you actually need.
Water demand can be very different for different properties.
Residential Property
Water may be required for:
- Bathrooms
- Kitchen
- Cleaning
- Gardening
- Storage tank filling
Housing Society
Demand may include:
- Multiple flats
- Common areas
- Landscaping
- Larger storage tanks
Agricultural Farm
Water demand may depend on:
- Crop
- Irrigation method
- Farm area
- Irrigation schedule
Industrial Property
Requirements may include:
- Process water
- Cleaning
- Cooling
- Utility water
- Staff facilities
Understand Pump Discharge
Discharge means how much water the pump can deliver over a certain period.
A higher discharge is not always better.
The required discharge should match:
- Borewell yield
- Water demand
- Storage tank size
- Delivery height
- Irrigation system
- Daily operating time
Example
If your borewell naturally gives water slowly, installing a very high-discharge pump may draw water faster than the borewell can recover.
This can cause operating problems.
The pump should therefore match the available groundwater and application.
Choose Pump HP Based on the Complete Requirement
People often ask:
“How many HP pump do I need?”
There is no single HP suitable for every borewell.
Pump power depends on:
- Borewell depth
- Water level
- Total head
- Required discharge
- Delivery height
- Pipe size
- Application
- Operating hours
Instead of selecting HP first, calculate the required performance first.
Then choose a pump model that can provide that performance efficiently.
Oversized vs Undersized Submersible Pump
| Factor | Undersized Pump | Oversized Pump | Best Solution |
|---|---|---|---|
| Water Delivery | May be too low | May be higher than needed | Correct sizing |
| Tank Filling | Slow | Fast but not always suitable | Correct sizing |
| Energy Use | May run longer | May consume unnecessary power | Correct sizing |
| System Match | May lack required head | May exceed borewell requirement | Correct sizing |
| Performance | Poor under high demand | Can stress system if poorly selected | Correct sizing |
Check the Borewell Diameter
The pump must physically fit inside the borewell casing.
Before purchasing, confirm:
- Bore diameter
- Casing diameter
- Pump outside diameter
- Cable space
- Delivery pipe arrangement
A pump that is not suitable for the borewell diameter can create installation problems.
Always provide the installer with the actual borewell dimensions.
Select the Correct Delivery Pipe
The delivery pipe carries water from the pump to the surface.
Pipe selection affects water flow and system performance.
Important factors include:
- Pipe diameter
- Pump discharge
- Installation depth
- Water pressure
- Pipe strength
- Connection quality
Jaldhara’s installation process includes fitting the pump, delivery pipe, cable and related accessories as one complete system.
Do not select the pump and pipe separately without checking whether they work well together.
