The Chinchilla Beneficial Use Scheme involves the release of treated water into the Chinchilla Weir, mainly for use by irrigators. The release of treated water into Chinchilla Weir is regulated under Beneficial Use Approval ENBU02701811.
Condition C28 of this approval requires SunWater to prepare and publish quarterly water quality monitoring data reports.
