Monash has constructed rain gardens, gross pollutant traps, infiltration trenches and bioswales throughout the municipality to collect and clean rainwater from urban catchments before flowing into streams and the surrounding environment.
Rain Gardens use a process called bio-filtration, where plants and soil filter out pollutants such as Nitrogen, Phosphorus, oils and heavy metals from rainwater and storm water. This improves the water quality entering our local creeks and the Bay. It also reduces the volumes of storm water runoff, reducing erosion in our waterways.
Gross pollutant traps are structures that use physical processes to trap solid waste. They mostly remove non- biodegradable large pollutants.
Infiltration trenches are an excavation filled with porous material, allowing for run off collection. They dissolve pollutants and provide water to plants, where vegetated, during dry periods.
Swales are linear depression channels that provide stormwater collection and conveyance. They can be grass-lined or more densely vegetated and landscaped.
Rain Gardens in Monash:
Glen Waverley North Reserve Pavillion
Rain water runs off the pavilion roof, into rain water tanks and a series of swales run around the building to take any overflow of water. Water then crosses a bluestone ford in the road and ends up in the small retarding basin and storm water system.
For other information about the facilities available at Glen Waverley North Reserve, please see its listing under Parks and Recreation.

Eaton Mall uses a combination of two passive tree-pits under decks, three retaining wall planters, and one rain garden.
Eaton Street & Chester Street, Oakleigh 3166
Rain water runs off the roof of the community centre into tanks and then overflow runs into a swale. The lower car park run off is collected in a series of swales and bio-retention channels. The upper car park run off is directed into a series of rain gardens and falls down the mount and directed, along the swale and eventually enters the drainage system.

Napier Park Frog Bog
Napier Park has a constructed frog bog, where water runs off surrounding grassed areas and the car park. It travels along a swale, and collects in the pond before entering the creek.

16 Torwood Avenue, Glen Waverley 3150
Wellington Reserve Community Centre
Rain water runs off the Centre's roof into tanks, and then overflows into swales before finding its way into the drainage system.

36-42 Mackie Road, Mulgrave 3170
Holmesglen Valley Bio-Filter Wetland
Design and construction of the Bio-filter is a joint project between Monash City Council and Melbourne Water to establish a native landscaped seasonal wetland and rain garden in Holmesglen Reserve, as part of the Living Rivers and Offset Programs.
The wetland is planted with a dense cover of wetland plants and covers an area 3,000 square meters, with a further 1,500 square meters planted with dry land plants.
The Wetland will not only retain storm water and bio-filter it before it enters Gardiners Creek, but will also provide habitat for native birds and other wildlife and improve amenity for the Holmesglen area.

Marianne Way Rain Gardens
The Marianne Way Retail Strip was beautified with the construction of a series of rain gardens trees ending in a rain garden bed.
In June 2009, Monash received a Keeping Australia Beautiful Award in the Water Conservation Award category.
Marianne Way, Mount Waverley 3149
Atherton Road Streetscape Enhancement
A series of rain garden tree pits were constructed along Atherton Road to beautify the streetscape and improve water quality draining into stormwater and reduce volumes.
The tree tips (grates) are specially designed to allow water to drain from the footpaths into the tree root-bed.
