The introduction of Murrumbidgee River water as a raw water source to Stromlo Water Treatment Plant has resulted
in increased risk of pathogenic micro-organisms to Canberra’s water supply. A project to enhance the existing
treatment process barriers was recently undertaken, involving the installation of an ultraviolet disinfection
This paper discusses the design and operation of the UV system as an additional treatment barrier, and outlines
the operational input into the different phases of the project. The operational impacts of the project during
construction and commissioning are also considered.
