Is this really the final design for this Alison Road stormwater drain @RandwickCouncil? It’s a huge missed opportunity for water sensitive urban design. Passive infiltration systems reduce stormwater flow, greatly improve beach water quality and look a lot nicer too.
I see this fairly awful Randwick stormwater inlet has now been naturally converted to a biofiltration system. Perhaps not the intention, but entirely predictable.
And I suppose this is why we can’t have nice things. What’s it been @RandwickCouncil? A fortnight?
I guess they figured they hadn’t run over enough of these plants, so they’ve now backed up for better coverage.
By Tuesday morning it was visibly clogged and the entire bunded 'basin' was full of mud. If not actively maintained soon, it will be as good as useless when the next downpour comes.
That next heavy downpour came this weekend and the drain did, indeed prove to be as predictably good as useless. It might just as well have been a concrete slab for all the water it appeared to drain.
The water still ends up in the stormwater system, it just has to flood across the footpath first, to make its way to the road and then into the kerbside drain.
