Hi there,

In this episode of Ideanthro we continue our recap of the recent Stormwater 2018 conference. One fascinating presentation at the conference was Jonas Larsen’s presentation about bioretention filter media. Jonas brings knowledge of soil science to the stormwater industry and demonstrates a very obvious (and easy to fix!) reason why bioretention systems often fail to support healthy plants.

Cheers

Hi there,

We recently returned from the Stormwater 2018 conference. This might sound funny, but we didn’t really have many expectations going in. Not low expectations, we just didn’t think much about it in the lead up. However it turned out to be a great conference. In this episode we discuss our 7 favourite things from Stormwater 2018.

The follow is a list of links relevant to the episode:

Regarding Brad Dalrymple’s presentation about stormwater offsets:

  • Keep an eye out of episode 259, where Brad and I will sit down for a chat about offsets and much, much more.

Regarding Alan Hoban’s presentation:

  • Refer to episode 213 for a discussion of water losses in bioretention.

  • Refer to episode 230 for a discussion of recent research which questions the conventional wisdom about how much pollution is generated by urban stormwater.

  • Refer to episode 231 for a discussion with Alan Hoban about how to deal with these challenging topics.

Keep an eye out for episode 260 where Jonas Larson and I will be chatting about his research.

Episode 253 is where you will find an example of a bioretention system being modified by the community for bike riding (relevant to the presentation by Sophia Findlay and Anna Milner).

Regarding Blue Mountains Council’s low cost bioretention systems and everything I love about them:

  • Episode 208 is where I wax lyrical.

  • Upcoming episode 261 is where I will soon be giving an update, 12 months on.

For a conversation with Mark Liebman about treating stormwater as a resource, refer to episode 211.

For footage of my introduction to the debate, scroll to the bottom of this page and sign up for the Ideanthro eNews… we’ll send it to you once we have a copy!

Hi there!

Time for another 'That's Like WSUD' episode of Ideanthro; where we take a concept that we have come across and relate it back to water sensitive urban design. In this episode, we're inspired by something that we heard from Aunty Ruby Sims at the Australian Institute of Landscape Architects' recent event 'Conversations with Elders'. Aunty Ruby advocated the importance of ‘process’. We're then surprised to realise it sounds very much like something we recently heard from a very different source!

Fascinating bioretention and a friend

Hi there,

So… it turns out that these bioretention systems have grown themselves a mini-series here on Ideanthro. We’re talking about it again.

Today we’re joined by Hermann Paulenz. Hermann watched the first two episodes about this bioretention system and he and I got into an interesting conversation in the comments on YouTube and LinkedIn. So interesting in fact that we figured that we should make a time to chat in person. That chat is what you see here.

In this episode, we discuss recent things that I have learnt about the site, and Hermann proposes some ideas for how to investigate the source of the sediment entering the bioretention systems.

Cheers

Hi there,

Today we have a viewer question. Our question comes from Dan Robson. You might remember Dan from episode 160 when he applied his horticultural knowledge to bioretention systems.

Dan’s question pertains to the last episode of Ideanthro (where we investigated a fascinating site with fix bioretention systems in series on a pseudo-natural channel). Dan asks whether sediment forebays or lower overflow weirs would have help prevent the sediment issues at this site.

Hi there,

Moss in bioretention. It's a topic we have explored a few times recently (Episodes 171, 172 and 243) Over that time we have pieced together a detailed understanding of how and when it grows in bioretention. It today's episode we find the perfect demonstration of this at play.

Hi there,

On today's episode Steph Brown shows us a bioretention system where the plants don't fit the typical mould. We're talking about a well integrated system in a mixed use development with ornamental species.

Hi there,

Monitoring the performance of stormwater treatment devices. It's about time we got to this topic in detail (we did touch on it briefly in Episode 185 - An Old Test). On the surface, monitoring the performance of stormwater treatment devices seems simply. Unfortunately it isn't. That's a pit, because it's an important topic. However a little knowledge about monitoring can guide us a long way. In this episode, Darren Drapper joins us to discuss the ins and outs of how to monitor stormwater treatment devices, as well as common pitfalls and challenges.

Hi there,

Making WSUD affordable. In our opinion it has to be one of the highest priorities for water sensitive urban design at present. To date, one of the best attempts at this has been Manningham City Council's Zero Additional Maintenance (ZAM) WSUD bioretention systems. We have spoken about these previously here and here. In this episode we catch up with Simon Brink from Manningham City Council and Harsha Fowdar from Monash University to discuss the latest ZAM WSUD news; specifically, recent research showing that multiple turf species deliver effective performance in bioretention systems. That is a big piece in delivering affordable bioretention!

In the episode Simon and Harsha refer to various ZAM WSUD documents available on the Clearwater website. Follow the link in the last sentence to take a look.

Hi there,

Time for another 'That's like WSUD' episode.

In his book When, author Dan Pink describes work by Lisa Khan that investigates the relationship between when people graduate and how far up the corporate ladder they climb. Long story short, the strength of the market at the time of graduation makes a big difference. Inspired by this we ask, "does the perception of WSUD at the time someone enters the stormwater industry affect how they relate to the concept throughout their career. Spoiler... we don't have an answer.

Hi there,

You've probably seen the transition to a water sensitive city diagram from Rebekah Brown. In this episode we use it to explain an idea. We hypothesise that water management in our cities is becoming increasingly complex. We propose that this is a problem that can guide our future water sensitive urban design efforts.

Hi there,

Today's episode is inspired by an almost 'passing' comment that Frank Blake (former CEO of Home Depot) made in an interview with Tim Ferriss. Frank explained how, whether in business, sport or life in general, we should be seeking to find the simplicity on the other side of complexity. In this episode we take that concept and relate it back to water sensitive urban design.

Hi there,

Today we jam a concept down your throat for the millionth time. The power of creating bush land style ecosystems in stormwater infrastructure. In this episode we show you a site you've probably never heard of before and argue that it provides a template to rehabilitate the worst cases of unattractive bioretention and detention basins in Australia.

Hi there,

Today we visit a streetscape bioretention system with a difference. The road it drains has one way crossfall. We take a look at why this can be a good solution.
