Although most domestic water bores in Perth and surrounds use slotted class 9 or class 12 PVC bore casing sometimes an alternative bore screen is used. In certain circumstances stainless steel wedge wire wrapped screens can be called for.

Why use a stainless steel bore well screen?
Examples of use of a stainless steel bore screen include where a higher water flow is required per lineal metre of screen, in some clay conditions and where only a narrow horizon of water bearing aquifer can be accessed. With an appropriate sieve analysis of the drilling fines, and the use of a correctly specified stainless steel screen with matching gravel packing, stainless steel bore screens can also be used to help keep out super fine sands.
Typically .5mm or 1mm slot size when used for domestic bores in Perth
