Setting the Standard for Water Quality in Critical Environments
AS 5369:2023 is the Australian Standard that defines the design, installation, commissioning, and maintenance requirements for water treatment systems in environments where water quality is critical to human health—especially in healthcare, aged care, and sterile processing facilities.
Compliance with AS5369 ensures that water systems are engineered to:
- Prevent microbial contamination
- Enable effective and safe disinfection
- Deliver consistent, high-quality water
- Support infection control and patient safety
At Western Water Solutions, we are proud to be recognised as industry leaders in AS 5369-compliant water treatment. From initial concept through to long-term maintenance, our end-to-end service model is trusted across Australia for its technical excellence and clinical reliability.
