Borewell Pipe Guide | A tube well is only as good as the pipe inside it. Whether you are drilling a new borewell for a farm, a house or a factory, the borewell pipe you choose decides how long the well lasts, how clean the water stays and how well the pump performs. This guide explains what a borewell pipe is, the main types, how to choose between 6 inch and 8 inch sizes, and how to install and care for it.
Quick answer: A borewell pipe (also called a boring pipe, tube well pipe or casing pipe) lines the drilled bore so that it does not collapse and the pump can draw water. Wells use plain pipe through most of the depth and slotted (strainer) pipe at the water-bearing layer. Choose the size by your pump diameter and water need, and the class by your depth and ground conditions. Six inch pipes suit many domestic and small farm wells, while eight inch pipes suit larger pumps and higher flow.
What Is a Borewell Pipe?
A borewell is a deep, narrow hole drilled to reach groundwater. Without support, the walls of the hole can cave in, and sand and soil can enter the water. A borewell pipe is the lining that prevents this. It keeps the bore open, holds back loose ground and gives the pump a clear path to the water. If you want to understand how wells work in general, see this overview of a water well and how an aquifer stores the groundwater that wells draw from.
In Pakistan you will hear the same product called boring pipe, borewell pipe, tube well pipe or casing pipe. They all mean the lining pipe of a tube well.
Main Parts of a Borewell
- Plain (blind) casing pipe: solid pipe that lines the bore where water should not enter.
- Slotted (strainer) pipe: pipe with cut slots, placed at the water-bearing layer to let water in and keep sand out.
- Gravel pack: clean gravel placed around the slotted pipe to filter the water and support the bore.
- Pump and pump column: the pump that lifts the water and the pipe that carries it up. See our water pumps and tube well accessories.
- Top seal: a seal at the top of the bore that keeps surface water and dirt out.
Plain Pipe vs Slotted Pipe
| Feature | Plain (blind) pipe | Slotted (strainer) pipe |
|---|---|---|
| Wall | Solid, no openings | Has cut slots |
| Where it goes | Through most of the bore depth | At the water-bearing layer only |
| Job | Holds the bore open and carries the pump column | Lets groundwater in while holding sand back |
| What to check | Class and wall thickness | Slot design and placement at the correct depth |
Placing slotted pipe at the wrong depth, or using the wrong slot size for the ground, is one of the most common reasons wells give less water or pull in sand. Your drilling contractor should identify the water-bearing layer before the pipes are placed.
PVC vs Steel Borewell Pipe
Both are used as casing, and the right choice depends on the well. PVC is made from polyvinyl chloride, and the rigid kind is called uPVC. You can learn the difference in our guide to uPVC vs PVC.
| Factor | PVC borewell pipe | Steel casing |
|---|---|---|
| Rust and corrosion | Does not rust or corrode | Can rust and corrode over time |
| Weight and handling | Lightweight, easy to lower into the bore | Heavy, needs more equipment and labour |
| Cost | Generally lower | Generally higher |
| Water quality | No rust staining | Rust can affect water over time |
| Best suited for | Most agricultural, domestic and general tube wells | Very deep or demanding bores |
For very deep wells or special ground conditions, ask your driller and your pipe manufacturer which class suits your bore. See our PVC boring pipes for the range we manufacture in Faisalabad.
6 Inch vs 8 Inch Borewell Pipe
Six inch and eight inch are among the sizes most often asked for in Pakistan. The right one depends on your pump and your water need.
| Factor | 6 inch borewell pipe | 8 inch borewell pipe |
|---|---|---|
| Typical use | Domestic and small to medium farm tube wells | Larger farms, bigger pumps and higher water demand |
| Pump size it can take | Smaller to medium pumps | Larger pumps with more clearance |
| Material use | Uses less material per length | Uses more material per length |
| Drilling | Needs a narrower bore | Needs a wider bore, usually a higher drilling cost |
| Price | Generally lower per length | Generally higher per length |
If your pump may be upgraded in the future, an eight inch casing leaves more room, but it also costs more to drill and to pipe. Do not choose by size alone. Choose by pump diameter, water need and your driller’s advice.
How to Choose the Right Borewell Pipe
- Start with the pump: the casing must be wide enough for the pump to fit inside with comfortable clearance.
- Think about water need: larger flow needs a larger pump, and therefore a larger casing.
- Consider depth and ground: deeper wells and loose or sandy ground need a suitable pipe class and correct slotted pipe placement.
- Check class and wall thickness: pick a class suited to your bore depth and loads.
- Check the joints: use matching joints and fittings. See our PVC fittings and solvent cement.
- Buy from a reliable manufacturer: even wall thickness, correct markings and consistent quality protect your investment.
Installation Best Practices
These are general guidelines. Always follow your drilling contractor’s instructions.
- Inspect every pipe for cracks or damage before lowering it.
- Keep the bore straight and clean, and make sure it is wider than the casing.
- Lower pipes slowly and evenly. Never drop, hammer or force them.
- Place slotted pipe only at the water-bearing layer, and plain pipe in the other sections.
- Join the pipes with the correct joint method and let joints cure fully [confirm: threaded or solvent cement].
- Fill the gravel pack around the slotted section and seal the top of the bore to prevent contamination.
- Flush and develop the well to clear sand before installing the pump.
Care and Maintenance
- Keep the top of the borewell sealed and covered so that dirt and surface water cannot enter.
- Watch for changes such as sand in the water, falling flow or unusual pump noise, and have the well checked early.
- Do not run the pump dry or beyond the well’s capacity.
- Keep records of the pipe sizes, depth and pump details for future repairs or upgrades.
Common Mistakes to Avoid
- Choosing the casing before the pump: the pump may not fit, or may have too little clearance.
- Buying only on price: thin or uneven pipe can fail under soil pressure and cost far more to fix.
- Wrong slotted pipe depth: low yield or sand in the water.
- Rough handling: dropped or hammered pipes can crack.
- Skipping well development: sand left in the well can damage the pump.
- Mixing joint types or sizes: weak joints and leaks.
Borewell Pipe Price in Pakistan
People often search for the price of a 6 inch or 8 inch borewell pipe. There is no single fixed rate, because the price depends on pipe size, class and wall thickness, whether the pipe is plain or slotted, the quantity, the delivery location and current raw material rates. To understand how pipe pricing works and how to compare quotes fairly, read our guide to pipe price in Pakistan.

Frequently Asked Questions
What is a borewell pipe?
A borewell pipe, also called a boring pipe, tube well pipe or casing pipe, is the lining of a tube well. It keeps the bore open, holds back soil and sand, and carries groundwater to the pump.
Which is better, a 6 inch or an 8 inch borewell pipe?
It depends on your pump and water need. Six inch pipes suit many domestic and small farm wells, while eight inch pipes suit larger pumps and higher flow. Choose by pump diameter and your driller’s advice.
What is the difference between plain and slotted pipe?
Plain pipe has a solid wall and lines most of the bore. Slotted pipe has cut slots and is placed at the water-bearing layer, so that water enters while sand stays out.
Is PVC good for borewell casing?
Yes. PVC does not rust or corrode, is lightweight and usually costs less than steel, so it is widely used for many tube wells. Very deep wells or special conditions may need a different class, so please consult your pipe manufacturer.
