Grasses Used to Help Purify Sewage
The plant at Forrest Hill, west of Brisbane, is using floating mattresses of plants to purify sewage.

Queensland Urban Utilities said the trial was a Queensland first and involved growing native varieties of grass on specially engineered plastic mattresses.

They have been used to grow 400 varieties of wetland grass plants, which draw toxins out of the water — things like carbon, nitrogen and phosphorus. It's a natural way to cleansing the waste water, that does not require chemicals or electricity.

Once the water is treated by the native grasses, it is purified with chlorine and then pumped to a local farmer who uses it for irrigating his crop.

Our Government Cannot Stop all Invaders – Take Matters into Your Own Hands - Our government cannot stop all invaders at our borders. Sometimes you need to take matters into your own hands. Plants that come into the United States from abroad can choke our crops, native plants and gardens or cause algae blooms that kill fish. They can even poison animals. Invasive species threaten our environment, our economy and our health. The flood of plants and food that come in through ports and airports potentially brings in pests, disease and harmful plants.
