Casings are large-diameter pipes made from materials like steel or uPVC inserted into the drilled hole to stabilize the bore and prevent collapse. GI pipes or column pipes, are then placed inside the casing to convey water to the surface.

Key functions of casing and pipes 

• Structural Support:

Casings stabilize the borehole walls, preventing them from collapsing due to soil pressure, which is crucial for the well's longevity. 

• Contamination Prevention:

Casing prevents the surrounding earth from caving into the borehole, especially in loose or unstable soil conditions. 

• Efficient pump operation: 

A properly cased borewell provides a smooth channel for the installation and operation of submersible pumps, reducing friction and improving efficiency.

• Separation of aquifers: Casings can be used to isolate different zones within the borehole that may have varying pressures or fluid types.

• Water delivery: Production or column pipes carry the water from the pump up to the surface for use.  

Proper maintenance

To ensure the long-term health of your borehole, proper maintenance is essential.

• Professional installation: Use experienced professionals to assess site conditions and install the correct casing materials and a quality gravel pack.

• Regular inspections: Periodically inspect exposed components for damage or leaks. Schedule annual checks with a qualified technician to assess the entire system, including downhole components.

• Water quality testing: Test your water annually for bacteria, chemicals, and heavy metals. This helps identify any contamination issues early.

• Cleaning services: Have the borehole professionally cleaned to remove sediment, bacteria, and mineral buildup. This may involve chemical or mechanical methods, such as airlifting.

• Monitor performance: Watch for signs of declining performance, such as reduced water flow, pump cycling, or changes in water taste, smell, or clarity. 

Pipes and casings are not just structural components—they are the foundation of a safe, efficient, and sustainable water supply. Investing in high-quality materials and professional installation ensures your borehole remains productive for decades. Whether you're tapping into a shallow aquifer or drilling hundreds of meters deep, never underestimate the importance of a strong backbone.
