Approximately 30% of the contaminated sites regulated by the Department of Environment, Climate Change and Water (DECCW)1 under the Contaminated Land Management Act 1997 (CLM Act) are the result of leaking UPSS.

Contamination from leaking systems can be very expensive to clean up when it goes unchecked for a prolonged period.

A proactive approach to prevent leaks from occurring in the first place is in the interest of both site owners and the general community.
