Responding to the Australian water sector’s request for more cost-effective application of technologies, the Australian Water Recycling Centre of Excellence, working alongside regulators, water utilities and the private sector, developed a way to achieve national consistency in the validation of treatment technologies as part of the Australian Government funded NatVal program. This validation framework (WaterVal) is underpinned by Validation Protocols, which are independently developed and agreed methodologies to assess pathogen removal using water treatment technologies. The framework and protocols are applicable to a broad range of water sources, and complement the objectives of the Australian Guidelines for Water Recycling and the Australian Drinking Water Guidelines.

The WaterVal IP was transferred to Water Secure Innovations Limited at the end of the AWRCE and subsequently transferred to WaterRA in 2018. WaterRA is making these same Protocols available while it works with the water industry to determine the future of WaterVal.

Please contact the WaterRA Team for further details.


"The WaterVal protocols were originally developed by the former Water Recycling Centre of Excellence (AWRCE)as part of the NatVal program and have since been transferred to Water Research Australia from Water Secure Innovations Ltd. We have not independently verified or updated the content of the WaterVal protocols.

 As with all content made available on our website, the WaterVal protocols are therefore provided for information purposes only and any use or reliance on the protocols is at your own risk. We do not make any representation or warranty as to, the accuracy, reliability, currency or fitness-for-purpose of the protocols. To the fullest extent permitted by law, we exclude (and you release us from) all rights, remedies, guarantees, liability and damages in respect of the use of or reliance on any aspect of the WaterVal protocols.
