Stormwater

Stormwater is essentially rainwater - water that hits our roofs, driveways, roads and pavements collecting anything and everything in its path and carrying it into the stormwater pipes located beneath our cities and towns. These pipes carry the water into the canals, creeks and rivers that eventually flow into the ocean.

of Stormwater

What is little discussed and often underestimated, is the type and amount of debris collected by stormwater.

More than just bags, bottles and solid waste, the water carries with it soil and sediment; chemicals from our roads, gardens and homes; oil and grease; rubber from our tyres; and leaves and animal droppings. All this material makes its way into our natural water systems and eventually our oceans – and the impact is catastrophic.    

LEAVES

Leaves and other seemingly harmless plant matter is collected by heavy rains and pushed into our water system through the stormwater network. Although degradable, excessive green waste increases the nutrient loads that cause toxic algae blooms and the subsequent imbalance in these water ecosystems.

SEDIMENT

Increased housing and urban development has made sediment polluted water a growing problem. Causing cloudiness, sediment prevents animals from finding food and can affect their breathing and resistance to disease. Sediment also increases the cost of treating water for human consumption, impacting odor and taste.

PLASTIC POLLUTION

8 million tonnes of plastic enter our oceans every year, with over 80% of that originating form land sources. Effective stormwater management can stop these contaminants before they reach our precious waterways.

TYRE RUBBER

Next time you break, speed up or ‘take the curve’ your tires will be leaving behind thousands of rubbery fragments now referred to as ‘microrubbers’. In heavy rain, these fragments are carried into our waterways becoming the nemesis of our marine animals and shellfish. Like microplastics they are often consumed, however tyre particles contain oil and other heavy metals, forming a lethal diet for all who consume.

CHEMICALS

Chemicals designed to kill weeds and bugs often don't discriminate. Finding their way into our water networks though absorption and run off, they are a primary contaminate. Chemicals and pesticides make water unsuitable for human and animal consumption, and agricultural use.
