Zero additional maintenance WSUD 1


Hi everyone,

I recently had the chance to take a look at Manningham City Council’s ZAM WSUD assets. Now before you go asking what ZAM WSUD means, and more importantly whether the acronym has anything to do with magic and wizards zapping and ZAMMING our problems away, I want to say a big thankyou to Simon Brink at Manningham Council for showing me around and sharing heaps of knowledge with me! Thanks Simon!

Yep, the name is meant to conjure up images for wizards.

Given the Australian water sectors love of puns and acronyms I’m not surprised. Think MUSIC (the Model for Stormwater Improvement Conceptualisation). Think DAnCE for Water (Dynamic Adaptation for eNabling City Evolution for Water.

More importantly though it stands for Zero Additional Maintenance. The concept being to design stormwater treatment systems that don’t require any more maintenance than the land that they are built on would require if the system wasn’t there.

If the system is built on what would otherwise be a grassed verge, then it needs to be as easy to maintain as a grassed verge.

If the system is built on what would be a landscaped area, then it needs to be as easy to maintain as that landscaped area.

You get the idea.

Simon showed me around quite a few of their systems and explained the different techniques and designs that they are testing and I took the opportunity to make two videos for you in order to show you a few things about each system that I found interesting.

In this first episode we look at a ZAM WSUD system in the streetscape. It is a bioretention system with turf on the surface and a few other nifty tricks being tried out to keep maintenance costs down.

In the second video we look at a planted system on a street corner.

If you want to know more about the project, you can find the ZAM WSUD handbook on the Clearwater website.
