UV Disinfection for Non-Potable Reuse and EPA Compliance
Failure of the existing UV disinfection system at the Kyneton Water Reclamation Plant created compliance risk for both EPA-licensed discharge and non-potable reuse. The plant treats domestic, commercial and industrial wastewater from over 3,000 customers, with treated water reused for non-potable applications or discharged to the Campaspe River.
Replacement components were unavailable, requiring a rapid solution to restore treatment capability. FILTEC installed an interim UV reactor to maintain operations, followed by design and installation of a permanent Trojan UV3000Plus open-channel system. The upgraded plant now provides reliable disinfection performance supporting both reuse and discharge requirements.
Restoring Disinfection Capability and Compliance Continuity
The failed Berson UV system reduced disinfection reliability and created EPA compliance exposure. The plant required a solution that could:
Restore disinfection quickly
Maintain plant operation
Support reuse and discharge compliance
Integrate with existing controls
Improve reliability and maintainability
The upgrade needed to minimise disruption while re-establishing a robust, compliant disinfection barrier.
UV System Replacement with Temporary UV Reactor Installation
FILTEC implemented a staged UV replacement strategy to restore and upgrade disinfection capability. The scope included:
Hire UV reactor installed within seven days
Permanent Trojan UV3000Plus system
Replacement of failed legacy UV units
Reliable open-channel UV disinfection
The staged approach maintained treatment continuity while enabling transition to a modern UV platform.
Mechanical, Electrical and Process Integration
FILTEC completed the installation and integration works required to connect the new UV system into the operating plant. The scope included:
Pipework modifications
Valves and actuators
Recirculation cooling system
Electrical and control integration
Staged installation works
Coordinated delivery supported smooth installation while minimising disruption to plant operations.
SCADA Integration and Automated Operation
The upgraded UV system was integrated into the plant’s control environment for remote monitoring and automated operation. The system includes:
SCADA integration
RTU and PLC connection
Duty/standby switching
Remote monitoring and control
Reduced manual intervention
Automation improved operational visibility and enabled efficient management across Coliban Water’s network.
Reliable UV Disinfection for Water Reuse and Discharge Compliance
The upgraded Kyneton Water Reclamation Plant now delivers:
Reliable UV disinfection
Restored EPA compliance capability
Support for non-potable reuse
Improved automation and control
Ongoing serviceability
Through rapid response, staged delivery and integrated system design, the project strengthened disinfection reliability and supports sustainable water reuse outcomes for the Kyneton community.
