There are different water classes which can be used in accordance with an EPA Victoria-approved fit-for-purpose application.
Waste water is treated to a standard that is specified for non-drinking domestic use, and referred to as Class A recycled water. Once treated, this water is delivered to your home through a separate (purple) pipe system.
Class A recycled water is produced according to strict guidelines developed by EPA Victoria and the Department of Health. These high standards are ensured through process control and quality assurance systems including continuous monitoring throughout the treatment facility.
