Build a Raingarden
When rain falls on natural, vegetated areas (such as a forest) it is filtered by soil and plants and soaks into the ground. When rain falls on hard, impervious surfaces (such as rooftops and roads) it cannot soak into the ground and becomes stormwater runoff.
Stormwater runoff picks up pollution such as sediment (mud), chemicals and litter, carries them into stormwater drains and out into our waterways. These pollutants are harmful to fish and other marine life.
Raingardens are garden beds that use native plants and soil to capture, filter and treat stormwater runoff. Building a raingarden on your property is an easy and inexpensive way to improve the healthy of local waterways and create a beautiful garden.
Bulimba Creek Catchment Coordinating Committee and Healthy Waterways teamed up to build a raingarden at the office at the Bulimba Creek Sustainability Centre. A video was made to show just how fun and simple building a raingarden is.
If you would like more information on how to build a raingarden, Healthy Waterways has produced a ‘how to’ factsheet.
Water Sensitive Urban Design
Water Sensitive Urban Design (WSUD) is a set of principles that can be applied to sustainably manage water, providing opportunities for the development industry, local government and their communities to achieve more liveable cities with vibrant and healthy waterways.
The major issue affecting waterway health in South East Queensland is the increased amount of mud (or sediment) entering our waterways.
What You Can Do
We all have a role to play in keeping our waterways safe and clean. There are a number of things you can do at home to help prevent sediment pollution:
- Mulch your garden beds to reduce run-off
- Sweep up dirst and mud rather than hose it down the drain
- Plant more native shrubs and trees.
