It’s illegal to dispose of concrete waste and slurry through New Zealand’s stormwater systems. So, if you’re doing any work or renovations involving concrete, you need to have slurry and wastewater controls in place before commencing. This usually involves hiring a professional to manage the waste.
Why concrete runoff is toxic for the environment
The disposal of concrete waste or slurry into our stormwater systems creates a highly toxic environment that can damage our fragile aquatic ecosystems.
The biggest component of cement is lime, which can be found in all concrete products.
When lime in cement dissolves in water it produces an alkaline solution that can kill insects, fish, and plants.
Concrete waste and slurry also contain toxic metals that have a high pH level of around 12.
The safe pH level for an aquatic life habitat is between 6.5 and 9.
What you need to know
Use a pro
Hire a professional to manage the disposal of your concrete waste and slurry. The consequence of incorrectly managing the waste yourself can result in a large fine.
Don’t pour waste down the drain
Avoid emptying your concrete waste or slurry into the drains of the stormwater systems. Doing this is toxic for our environment, as all the drains lead to our oceans and can harm marine life.
Don’t try to dilute the concrete waste
Never try to dilute concrete waste or slurry. It takes over 100,000 litres of fresh water to dilute only one bucket. This is why it is best to call in a professional for correct management.
Don’t let the concrete waste set
If you’ve left organising your concrete waste disposal to the last minute, try sweeping or shovelling the slurry into a pile for disposal. Don’t leave it to the point where it sets.
