IWSFG Flushability Specification

The IWSFG received an overwhelming response to its initial Publicly Available Specification (PAS) document released in July 2017. Thank you to all of those organisations and individuals who provided comment, almost all of whom have allowed their comments to be attributed. These comments will create a more robust specification.

The submitted comments were considered at a meeting of the IWSFG in September 2017. Given the extensive nature of the comments and the significant implications for the PAS documents, the IWSFG considered that the most effective course of action was to release an updated version of the PAS documents in conjunction with the comments and the IWSFG responses. Hence the delayed timing in responding to the comments.

The comments have resulted in a major revision to the PAS documents, with the original 13 documents now reduced to three. The IWSFG considered that the most effective and meaningful way then to present the comments and responses was against these three revised PAS documents. These documents encompass PAS1: Criteria for Recognition as a Flushable Product, PAS2: Terms and Definitions, and PAS3: Disintegration (Slosh Box). The comments against the other PAS documents resulted in the removal of these PAS documents to avoid confusion and unnecessary duplication. Based on this, the IWSFG did not believe that there was value in publishing individual comments and responses against these deleted documents.

The IWSFG presents three PAS documents as defining the criteria and tests required to determine if a material flushed down the toilet is compatible with the downstream sewerage network. We invite you to provide comments on the revised PAS documents using the template provided. Comments are requested in Excel format, using the form provided. If the organisation or individual requires a PDF or similar format to be submitted to avoid alteration of content, then we request that this is submitted in addition to the Excel formatted comments. The closing date for comments is March 2, 2018.

Please note that all submissions will be made public and all comments attributed to the relevant organisation or individual submitting them unless specifically requested to be confidential.  In this case the comments will be made public, but the author will be named as anonymous.

The final flushability criteria are expected to be published in April 2018, initially in English with the intention to translate into other languages over time.
