uPVC Well Casing Pipes vs uPVC Borehole Column Pipes
uPVC Well Casing Pipes vs uPVC Borehole Column Pipes: What Is the Difference?
When planning a borewell or groundwater extraction system, two pipe types are often confused: uPVC well casing pipes and uPVC borehole column pipes.
Although both are used in borehole applications, they perform completely different functions.
The simple way to understand the difference is:
uPVC well casing pipes protect and support the borewell, while uPVC borehole column pipes connect to the submersible pump and carry water toward the surface.
Understanding this difference is important when selecting pipes for agricultural, domestic, commercial, and industrial groundwater projects.
What Are uPVC Well Casing Pipes?
uPVC well casing pipes are installed to line and protect the drilled borewell.
During drilling, the surrounding geological formation may contain loose soil, sand, gravel, or fractured material. Casing helps maintain the structure of the borehole and reduces the possibility of unwanted material entering the well.
FieldFlow Greens offers plain and pre-slotted uPVC well casing pipes for borehole and groundwater applications.
Main applications of uPVC well casing pipes
- Borewell construction
- Groundwater extraction
- Agricultural boreholes
- Domestic water wells
- Industrial water supply
- Tube wells
- Deep boreholes
- Groundwater projects
Plain and Screen Casing Pipes
Plain casing pipe is used in sections where groundwater is not intended to enter directly through the pipe wall.
Screen casing pipe contains slots that allow groundwater to enter the borehole while helping control the entry of larger formation particles.
The position and length of the screen section should be determined according to the geological and groundwater conditions of the borehole.
What Are uPVC Borehole Column Pipes?
A uPVC borehole column pipe is used with a submersible pump installed inside a borehole.
Its primary purpose is to provide a connection between the submerged pump and the water delivery system at the surface.
In simple terms:
Submersible pump → uPVC borehole column pipe → surface water delivery
The borehole column pipe must therefore be selected according to the pump, installation depth, operating pressure, water flow and required pipe diameter.
FieldFlow Greens offers uPVC borehole column pipes designed for submersible pump installations and borehole water applications.
uPVC Well Casing Pipe vs uPVC Borehole Column Pipe
Feature | uPVC Well Casing Pipe | uPVC Borehole Column Pipe |
Primary purpose | Protect and support the borehole | Connect and support the submersible pump |
Main application | Borehole construction | Submersible pump installation |
Water function | Screen allows groundwater entry | Carries pumped water upward |
Position | Forms part of the borehole structure | Installed with the pump inside the borehole |
Available design | Plain and slotted | Pump riser/column design |
Main consideration | Borehole geology and groundwater formation | Pump load, pressure and installation depth |
Connection requirement | Secure casing joints | Strong pump-column connections |
Typical users | Borewell drillers and contractors | Pump installers, farmers and irrigation contractors |
The important point is that these two pipes are complementary rather than interchangeable.
Why Are uPVC Well Casing Pipes Important?
A borewell is essentially a constructed opening through different underground formations.
Without suitable casing, unstable formations can create problems for the borewell.
A properly selected casing system helps:
- Maintain borehole stability
- Protect the borehole structure
- Control the entry of formation material
- Provide a suitable groundwater collection zone
- Separate different sections of the borehole
- Support long-term groundwater extraction
The screen section is particularly important because it allows groundwater to enter the well.
The exact screen opening and placement should be selected according to the geological formation and groundwater conditions.
Why Are uPVC Borehole Column Pipes Important?
Once the borehole has been constructed and the submersible pump is installed, another challenge appears:
How will the water reach the surface?
This is the job of the borehole column pipe.
The pipe is connected to the submersible pump and carries the pumped water upward.
A borehole column pipe must therefore be capable of handling the conditions created by:
- Pump weight
- Water pressure
- Installation depth
- Pump discharge
- Repeated operation
- Joint loading
- Borehole conditions
This makes the column pipe an important structural and hydraulic component of a submersible pumping system.
Are Borehole Casing Pipes and Borehole Column Pipes the Same?
No.
This is one of the most important distinctions for buyers.
The uPVC well casing pipe forms part of the borehole construction.
The uPVC borehole column pipe forms part of the submersible pump installation.
They may both be manufactured from uPVC, but their engineering purpose is different.
Using the wrong product simply because the diameter appears suitable can result in an inappropriate borehole installation.
Can a uPVC Well Casing Pipe Be Used as a Borehole Column Pipe?
It should not automatically be assumed that a casing pipe can replace a borehole column pipe.
A casing pipe is designed primarily for borehole support and groundwater entry.
A borehole column pipe is designed for pump support and water delivery.
The column pipe also needs an appropriate connection system capable of handling the pump and operating conditions.
Therefore, the two products should be selected according to their intended application.
Can a Borehole Column Pipe Replace Well Casing?
Again, no.
A borehole column pipe does not perform the same structural role as well casing.
The casing is selected based on:
- Borehole diameter
- Geological formation
- Groundwater conditions
- Screen requirements
- Borehole depth
The borehole column pipe is selected based on:
- Submersible pump
- Pump discharge
- Pump installation depth
- Required diameter
- Operating pressure
- Connection system
This is why a complete borehole design should consider both products separately.
How Do They Work Together in a Borehole?
A simplified groundwater system looks like this:
Ground formation
↓
uPVC well casing / screen
↓
Groundwater enters through screen
↓
Submersible pump
↓
uPVC borehole column pipe
↓
Water reaches surface
↓
Irrigation / water distribution system
This explains why the two pipes should not be viewed as competing products.
They perform different stages of the same groundwater system.
Which Pipe Is Required for an Agricultural Borehole?
In many agricultural groundwater projects, both casing and borehole column pipes may be required.
For example, an agricultural borehole may use:
- uPVC well casing to construct and protect the borehole
- Screen casing in the groundwater-bearing zone
- Submersible pump for water extraction
- uPVC borehole column pipe to lift water
- HDPE or other surface pipeline for distribution
- Drip irrigation or sprinkler irrigation for crop watering
FieldFlow Greens’ broader product portfolio includes both uPVC well casing pipes and uPVC borehole column pipes, along with agricultural irrigation products such as drip irrigation systems, sprinkler systems, filters, valves and fittings.
This makes the company relevant to projects that extend from groundwater extraction to agricultural irrigation.
How to Choose the Right uPVC Borehole Column Pipe
Choosing a borehole column pipe should start with the pump specification.
Consider:
- Pump Size
The column pipe diameter should be compatible with the submersible pump and required water flow.
- Borehole Depth
Deeper installations can create greater loading and pressure requirements.
- Pump Weight
The column pipe and its connections must be suitable for supporting the installed pump assembly.
- Operating Pressure
The pipe should be selected according to the pressure conditions of the pumping system.
- Joint Design
A secure connection is essential because multiple pipe sections may be joined to reach the required installation depth.
- Installation Conditions
The borehole diameter, water conditions and installation method should also be considered.
