Improve our waterways and the stormwater network with eco design practices and devices:
- Permeable surfaces, such as lawns, reduce the amount of stormwater going into drains.
- Retention tanks collect runoff water from hard surfaces and store it during a storm.
- Rain tanks are the same as retention tanks but are often used in rural areas.
- Soakage trenches along edges of paving help the ground absorb more stormwater.
- Rain gardens allow stormwater to soak through the soil, filtering out sediment before it goes through drains. They reduce the amount of pollution reaching our waterways.
- Living roofs are roofs with vegetation. They absorb rainwater and improve insulation.
- Mulching keeps moisture in the soil and helps slow the flow of stormwater. Dried leaves or wood chips make for good mulching.
