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.
