Water pollution: The crime that's hard to avoid

Manufacturers, builders and developers need to be especially careful.

AustraliaReal Estate and Construction

The offence of water pollution in the Protection of the Environment Operations Act 1997 (NSW) is so broad that almost anyone could be issued a $30,000 on-the-spot fine for breaching it.

Manufacturers, builders and developers need to be especially careful, as runoff of even benign material like sand or soil can lead to pollution and attract penalties of more than $2,000,000.

What is water pollution?

Under section 120(2) of the Act, it's an offence to cause or permit any waters to be polluted.

The term 'waters' is not limited to lakes, streams or oceans, but could be any natural or manmade watercourse, including stormwater drains or sewerage pipes.

The offence is not limited to the common meaning of pollution. The word 'pollute' in section 120 is defined so broadly that it includes the addition of any matter whatsoever into waters if that matter changes the state of that water. This includes things like soil, leaves, motor oil, coffee grounds, or litter.
