Driveway Paving

This Fact Sheet details the different options that are available for designing your driveway with either a centre grass strip , permeable paving, or diversion into a raingarden or infiltration pit.

Infiltration Raingarden

An infiltration raingarden is essentially a depression in the garden which allows water to soak into the ground; the raingarden is filled with a sandy loam soil and can have an underlying gravel trench. Refer to this Fact Sheet to find out how to design and size your raingarden.

Infiltration Trench

Infiltration trenches are gravel filled and designed to receive stormwater without losing valuable space in your garden. A trench can take water from a downpipe, overflow from tanks or pipes draining hard surfaces such as driveways and paving. Refer to this Fact Sheet on how to design and size your trench.

Rainwater tanks

Rainwater tanks are often installed at residential homes across Victoria. Whilst most home owners appreciate  the water and cost savings of harvesting water from their roofs, tanks can also protect the health of our local waterways. Refer to this Fact Sheet to see how installing a rainwater tank can result in multiple benefits.
