Rain! The dirty water flows!

By johnboy - 3 June 2009 36

With the first decent rain in ages I was down to the drains to take in the majesty of flowing stormwater.

The Bureau reports the weather will improve towards the end of the week before getting wet again late in the long weekend.

rain and school students dont mix. keeping kids locked up all day is torture for all concerned!!!

feel free to rain on down between about 3:30pm-8:45am. Why does it always seem to piss down right at 3pm?!!

We need something like that in the inner north. Hmmmm, I’m sure all those soccer mums and dads wouldn’t mind sharing some of the Dickson playing field with a few herons annd frogs.

LOL. At our club the Under7’s are the Herrons and the Under 8’s the Frogs.

No actually JB. With flooding it is the velocity of water that causes damage. Wet is wet, but mowed down is another thing altogether. Pondage is more important, and that’s the problem with so much filling going on. And narrow deep concrete channels remove a lot of that pondage too.

Constructed wetlands function as ‘detention basins’ holding up the first flush, but through ‘trickle pipes’ allowing a lot of the water to get away more sedately. These outlets are set at a lower level than the spillway so hopefully there is excess capacity in the dam when a storm event comes along – a full to the brim dam isn’t much help at all with flood mitigation.

And what clown killer said – spot on. For two years I have been pitching a similar solution for a site in Gungahlin opposite Burgmann School, and it finally looks like happening. There’s a meeting at the school about it next Tuesday night – details on our website.

The retro-fitted wetland behind O’Connor shops is an example of how that form of water retention might work. Thanks to the work of TAMS and the Sullivans Creek Catchment Group there’s another one of those wetlands going to be retro-fitted on Banksia Street. that said I doubt that there’s an engineered solution that would avoid the need for the Sullivans Creek to perform a storm-water function so I guess the concrete is here to stay.

Designing your house, garden and water management system is a great way to take the pressure off the storm water system. Choosing water permiable rather than hard paving surfaces, installing rainwater tanks and planting native species all helps.

There’s an artificial wetland in Evatt up near the soccer club. it works really well not only as habitat but also as a filter for the water.

is that what that is? i always thought it was a dumping ground for bogan cr@p.

What she said! Fair dinkum, people will grumble about the rain, and then move on to a complain about water restrictions!

And whenever a shower of rain encourages one to think the drought is over, just go to some ground and dig a little hole. The dry hard soil in there will reveal the true situation. You won’t need more than a little hole.

All that water rushing away from where it is needed. Why don’t they tear up those concrete river banks and create some wet land areas to store the water and give the birdies a home?

Not impossible to do both. I think TAMS intends to do something like this as part of the

Do you like sandbagging your home?
