Technical Specifications

WaterMark Technical Specifications (WMTS), previously known as Australian Technical Specifications (ATS), are individual material and product specifications to enable evaluation and certification under WaterMark in accordance with WaterMark Scheme Rules.

A WMTS may be generated where no approved specification, either a relevant existing Standard or WMTS, can be used for evaluating a plumbing or drainage material or product. For more information about developing a WMTS, refer to Procedures and Guidance and the Specification Development for WaterMark and the PCA Compliance infographic.

All current WMTS are listed below.
