GVW, in a statement, said that breaking into these sites was a serious criminal offence, treated as an act of interference with critical infrastructure.
Under laws such as the Protection of the Environment Operations Act, tampering with water systems, damaging infrastructure, or putting water quality at risk can attract substantial fines and significant legal consequences.
GVW added that trespassing, damaging assets, or interfering with water infrastructure could result in fines of up to $230,000 under Victorian legislation.
Because sites such as the Tongala Water Treatment Plant are essential to public health and safety, unlawful entry is dealt with far more severely than ordinary trespass.
Operations staff have discovered cut fencing on multiple occasions, as well as damaged and missing safety signage, prompting an increase in security measures.
They are also working closely with Victoria Police to identify offenders.
GVW general manager of service and delivery Dan Flanagan said repeated intrusions created serious risks — not only to the individuals entering an operational site, but to the security and integrity of Kyabram and Tongala’s drinking water supply.
“Water treatment and storage sites are highly controlled environments, and unauthorised access is treated as a major breach,” Mr Flanagan said.
“People breaking into our sites are exposing themselves to significant danger and our community to unnecessary risk.
“Beyond the legal consequences, there is a genuine safety hazard — these are active sites with deep water, chemical storage, moving equipment and restricted zones.”
Mr Flanagan said the repeated intrusions were also diverting staff time and resources.
“Every time a fence is cut or signage is removed, our teams must assess the site, complete security checks and make repairs,” he said.
“This is time taken away from essential daily operations that keep water safe and reliable for our customers.”
People can report anyone loitering, damaging fences or accessing GVW sites after hours by contacting police on 000, Crime Stoppers on 1800 333 000, or GVW’s 24/7 emergency line on 1800 454 500.
