Brimbank City Council has exceeded its target for developing alternative water sources and most targets for reducing water pollutants entering waterways, ahead of its 2022/23 goal.
Stormwater Harvesting Doubled
In 2014/15, we harvested 101ML of stormwater across systems at Cairnlea, Green Gully Reserve, Keilor Golf Course and Keilor Park Sports Field – double the 50.2ML target for that year.
Targets Exceeded for Pollutant Reduction
In 2014/15, we exceeded 2022/23 targets for reducing nitrogen and phosphorous. We achieved 88 per cent of the 2022/23 target for reducing suspended solids.
Lower Water Use Overall
While Council’s water use has increased since 2007/08 – water use across Brimbank is still significantly lower than it was prior to water restrictions – at just 59 per cent on 2002/03 levels. The increase is due to
In 2014/15 Council consumed 384ML of water. Our aim is to cut potable (drinking water) consumption to 184ML per year by 2022/23.
Sustainable Water Management Strategy
The Brimbank Sustainable Water Strategy highlights several actions Council will take to reduce potable water use including:
ongoing water efficiency works on Council assets, such as switching to warm season grasses on playing fields and open spaces
increasing the use of available stormwater for irrigation
constructing new stormwater harvesting projects – which, combined, will supply more than 70 per cent of irrigation demands by 2022/23.
The Sustainable Water Management Strategy update measures our progress against three target areas:
Chair of Brimbank Administrators Mr John Watson said Council remained confident it would achieve targets in all three areas by 2022/23 – despite an overall increase in the amount of water used in 2014/15, due largely to the easing of water restrictions in recent years and increased irrigation on playing fields in response to community need.
“Council has already achieved significant results in harvesting stormwater, diversifying its water sources and reducing stormwater pollutants. By working to further increase the harvesting and use of stormwater for irrigation purposes, Council aims to considerably reduce its water usage and costs as we approach 2022/23,” Mr Watson said.
