Wianamatta-South Creek Water Source 2025

• Following a fire at the Cooper’s Environmental Waste Recycling facility on Saturday 29 November, a ban on taking water from watercourses downstream of the facility is in place.
• This is a precaution as contaminants processed at the facility present a risk of harm to those who come into direct contact.
• Don’t take or use water from these watercourses for irrigation, drinking, cooking, filling swimming pools, washing cars, watering gardens, or other purposes.
• Polluted water may look and smell like clean water, but it is not safe to use.
• Regular tap water is completely safe to use.

Reasons for decision

Section 324 of the Water Management Act 2000 allows the Minister or delegate to order that temporary water restrictions within a water source(s) are to have effect for a specified period, if these restrictions are determined to be in the public interest.

Examples of the public interest referred to in section 324(1) are “to cope with a water shortage, threat to public health or safety or to manage water for environmental purposes”.
It is in the public interest to make an order to prohibit taking of water from watercourses downstream of the facility to cope with a threat to public health, for the following reasons:

• The Cooper’s Environmental Waste Recycling facility receives and stores hazardous chemicals, including polychlorinated biphenyls (PCBs) and is licensed by the NSW Environment Protection Authority (EPA).
• PCBs present a risk of harm to those who come into direct contact with it. PCBs are hazardous chemicals historically used in transformers as coolants and have been banned since the 1980s.
• Following the fire at this facility, it is possible these hazardous chemicals may have entered downstream watercourses. NSW EPA is monitoring water quality downstream for potential impacts, and has requested the Department takes measures to prevent extraction and use of potentially contaminated water.

Accordingly, the section 324 order is being made to cope with a threat to public health in the Wianamatta-South Creek Water Source.

The section 324 order also includes the ability to lift orders once the risk of exposure to potentially contaminated water has passed.
