Why not a Brownhill Creek stormwater harvesting opportunity.

As we close in on our decision on the way to go I ask Why not a Brownhill Creek stormwater harvesting opportunity?

 

Ridge ParkI refer to our resolution of August 2012 calling for “other methods not currently in use (to) diminish local flooding” to be explored. I am disappointed that no more stormwater harvesting opportunities have been identified than previously reported in the 2012 stormwater management plan. I say this particularly in relation to the potential offered by collecting stormwater for reuse in a flood control dam in Ellisons Gully, recognising that the economic benefits during drought of such an opportunity could make Option B2 more attractive.

Back in 2012 the City Unley called on the project to explore more stormwater harvesting opportunities. This was no idle request. We had taken the lead with the detention dam we recently completed up at Ridge Park in Myrtle Bank. This is a project that incorporated an aquifer recharge.

The Project was well aware of this project, having provided the design work for it. It is a project that achieve water harvesting outcomes on Glen Osmond Creek, noting the increase from 20 ML per annum to 60 ML per annum found for both flood control and water harvesting. This is contributing to the watering of Unley’s parks and gardens, saving our rate payers the cost of paying for water from other sources.

We have been told access into that aquifer is not possible in Ellisons Gully but my memory is we were told the same thing about Ridge Park. We pursued investigating this and found not only was it possible but we did it.

So Option D may yet have stormwater harvesting opportunities. The same can be said I suggest for Option B2.

So why not a Brownhill Creek stormwater harvesting opportunity? Why not explore if there is an ecologically and financially responsible solution.

    The reality is that you can vote with your heart, you have told us any number of times that is for a dam, and ask for more opportunities to harvest water in the same motion. It is time Unley Council made a decision!
