When it looks like bioretention but isn't

When it looks like bioretention but isn't

Hi everyone,

Way back in episode 16 we discussed how to tell if the bioretention system that you are looking at is indeed a bioretention system.

In today’s episode, the opposite.

How to tell that they thing you’re looking at which looks like bioretention according to what we said in episode 16 actually isn’t.

Hi everyone,

A clear example that bioretention systems are a harsh environment that a little shade can help!

Too much sediment to work right

Too much sediment to work right

Hi everyone,

In today’s episode. A bioretention system with a heap of fine sediment on the surface and yet it still drains quicker than the nearby sediment basins.

Hi everyone,

Does removing a (literal and physical) truckload of sediment from a bioretention system mean that ALL the plants need to go too?

It's canopy and understorey

It's canopy and understorey

Hi everyone,

On Ideanthro we tend to prattle on about how important it is to include trees in bioretention systems. Here’s the thing thought. Just saying “put trees in bioretention” doesn’t quite cut it because it implies that trees are the whole solution. They aren’t. Trees are a part of the vegetation in a well functioning bioretention system. They need to be used alongside understorey plants. In this episode we demonstrate one reason why.

Ecological niches in bioretention

Ecological niches in bioretention

Hi everyone,

It’s been a little while since we released an Ideanthro episode. We have more than a few interesting things going on and they’ve been consuming our time.

BUT!

Today one of those things provided us with a golden opportunity to film. So film we did.

We have recently been conducting condition inspections on Gold Coast City Council’s stormwater treatment assets. Some 376 of them in fact. In this episode we take a look at a very large bioretention system and discuss the ecological niches developing in it.

Find this asset as B01534 on The WSUD Map.

Language and new WSUD concepts

Language and new WSUD concepts

Hi everyone,

This episode is inspired by a (sort of) recent chat with Ben Penhallurick (you might remember Ben from episodes 78, 150 and 151). Ben and I were discussing the effect that the language that we use when introducing new WSUD concepts has on their long term success. Specifically, it feels to me like in our industry we have a habit of talking about new concepts with more certainly than they deserve. In the short term this might help with their uptake, but I argue that it shoots us in the foot in the long term.

Mediocrity

Mediocrity

Mediocrity.

On today’s episode we discuss a trend that we see over and over in the waterway health industry. In the short term, perhaps it delivers acceptable outcomes. In the long term it leads to mediocrity. It starts with a statement like “and the biggest threat to waterway health is…”

When being safe makes us less safe

When being safe makes us less safe

Hi everyone,

Can our attempts to make the world safer have unintended consequences?

In this episode a broken fence around a bioretention system inspires us to discuss a topic that crosses boundaries. Water. Environment. Human Movement. Workplace Health and Safety.

Bonds for financing WSUD

Bonds for financing WSUD

Hi everyone,

One of the big challenges confronting widespread adoption of WSUD is how to pay for it. We have discussed this before from several different angles including:

Today we tackle this from a new angle. We recently caught up with John Matthews from the Alliance for Global Water Adaptation. John is a conservation biologist who has developed a wide skill set, including an interest in finance; particularly green and climate bonds. This makes John a fascinating person to speak to about the challenge of funding WSUD.

In this episode John and I discuss what bonds are and how they can be used to secure funding for green initiatives. With all the attention that stormwater utilities are receiving in our industry are present, perhaps this is a nice complimentary approach?

At the end of the episode John mentions several links. These are:

More darn moss in another dang bioretention

More darn moss in another dang bioretention

Hi there,

So it looks like we’re still talking about moss in bioretention. After the last episode it seemed like we might have this wrapped up in a bow. In fact we do not. But we are still learning. In this episode we pull apart another piece of the ‘why did moss grow there?’ puzzle.

Low cost bioretention 12 months on

Low cost bioretention 12 months on

Hi there,

In this episode we revisit the low-cost bioretention systems constructed by Blue Mountains City Council to see how much they have changed in the year since we last saw them.

Thriving bioretention plants with Jonas Larsen

Thriving bioretention plants with Jonas Larsen

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.

Stormwater 2018 - Our seven favourite things

Stormwater 2018 - Our seven favourite things

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!

That's like WSUD - Process

That's like WSUD - Process

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

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

The bioretention that continues to fascinate

The bioretention that continues to fascinate

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.

Cheers

Jack
