Review stormwater module of AGWR

Review stormwater module of AGWR

The existing Guidelines for Stormwater, as set out in the Australian Guidelines for Water Recycling (AGWR) are over ten years old. The original stormwater module, due to significant data limitations, was based on default values calculated from sewage. There is a need for an updated review of available published and industry data on stormwater harvesting, as an evidence base upon which to develop more refined and specific guidance for the various types of stormwater which have a wide variety of water qualities.

Details

The Stormwater Harvesting and Reuse module is one of the three modules that comprise the second phase of the Australian Guidelines for Water Recycling, which address health and environmental risks associated with water recycling. The stormwater guidelines cover only non-potable (ie non-drinking water) potential end uses of roofwater and stormwater and extends the scope of Phase 1 of the water recycling guidelines (NRMMC– EPHC–AHMC 2006), which focuses primarily on reuse of wastewater and grey water.

Phase 1 of the AGWR has recently been reviewed (with oversight from EnHealth) and an updated draft is currently out for public consultation. An update of the Phase 2 module for stormwater harvesting and reuse, would bring it in line with the proposed changes to the Phase 1 document. In order to do this, there is a need to gather more recent water quality data for stormwater harvesting and reuse, and develop a scientifically rigorous, peer-reviewed and published evidence base upon which to develop more refined and specific guidance for the various types of stormwater.

It is proposed to undertake a state of knowledge review of the currently available data on stormwater quality and risks and use this new information to produce a peer-reviewed and published evidence base for a possible future update to the Phase 2 stormwater module.
