Adjusted according to well design, balancing maximum flow with structural integrity.
uPVC (Unplasticized PVC) Screen and Casing are widely used in water wells, boreholes, and groundwater extraction systems. These products are engineered to maintain structural integrity under subterranean conditions while providing corrosion resistance and a long service life. uPVC’s inherent properties—lightweight yet rigid—make it an ideal choice for water well installations.
Smooth external surface, typically used as a protective lining in drilled wells.
Features external ribs to minimize contact with borehole walls, reducing friction during installation and preventing damage.
Contains precisely cut slots or perforations that allow water inflow while filtering out sand and sediment.
Lining and protecting boreholes to ensure clean water extraction for homes, communities, and public water supply.
Provides an efficient water source for farms, ranches, and greenhouse irrigation systems.
Used in manufacturing facilities, water treatment plants, or industrial cooling processes.
Environmental testing wells where corrosion-resistant casings help maintain water quality and stable borehole integrity.
uPVC does not rust or degrade chemically in typical groundwater environments, ensuring a longer service life compared to metal alternatives.
Lightweight for easier handling and transportation, yet robust enough to withstand underground pressures.
Smooth interior and exterior surfaces resist scale buildup and minimize sediment adherence.
Compatible with standard threads or solvent-weld joints (depending on design), requiring minimal special tools.
Available in diameters from approximately 2" (50 mm) up to 12" (300 mm) or more, depending on the manufacturer.

Typically longitudinal or horizontal slots spaced around the circumference. Slot distribution and density can be customized to match the desired flow rate and filtration level.
The slot width (e.g., 0.3–1.0 mm) is selected based on aquifer conditions, ensuring efficient water inflow while preventing sand or sediment intrusion.
