Hi there!

In Australia, when talking about water sensitive urban design, we often talk about needing to achieve integrated outcomes with multiple benefits. Perhaps it is integrating stormwater with parkland. Perhaps it is integrating stormwater with streetscape landscaping. 

The irony of this is that we actually do a very poor job of integrating the environmental benefits of stormwater with the flooding and drainage arm of stormwater. This became abundantly clear when I recently visited The Netherlands. The on ground actions being taken are very similar to what we see in Australia (think bioretention, permeable paving and infiltration), but they're being built to reduce the risk and severity of flooding. 

So why is it that we don't give any credit to stormwater treatment systems for their flood management benefits?

Cheers
