A rain garden is generally a small structure using careful design and plant selection to remove soluble pollutants (nitrogen, phosphorus, potassium) and suspended solids from stormwater prior to discharge into downstream drainage systems and our waterways and bays.
Essentially rain gardens are:
- small basins but can also be larger scale bio-retention basins
- typically made up of multiple small gardens located throughout a catchment
- frequently located in medians, or traffic calming measures, on roads
A wide range of vegetation can be used within a rain garden, allowing them to be well integrated with the overall landscape theme of an area.
TGM projects involving the design of rain gardens include:
- Main Drive, Kew
- Yarra’s Edge River Precinct, Docklands
- Hede Street Industrial Subdivision, South Geelong
- Surrey Hills Railway Station carpark, Surrey Hills
- Sandhurst Estate Central Precinct, Sandhurst
TGM’s civil and water engineering divisions provide expert advice and design involving the use of rain gardens and water sensitive urban design (WSUD).
