Narrow diameter well screen

32 mm HDPE well screen is designed for the construction of groundwater monitoring wells for environmental investigation, groundwater sampling and water level monitoring.

Manufactured from natural high-density polyethylene (HDPE), the screen provides excellent chemical resistance without introducing heavy metals or plasticisers that could affect groundwater samples. The lightweight construction and 1m lengths makes it easy to handle and install in the field. The 32 mm filter pipe features 0.3 mm horizontal slots and can be combined with matching plain HDPE casing, caps and connection accessories to create a complete monitoring well installation.

Due to the narrow diameter this well screen is suitable for installation by hand using augers, gouges or handheld window sampling systems.
