Let’s end the week on a high note!
It turns out lots of people really do care about the treated sewage being pumped into the sea off Thunder Point by Wannon Water, with an incredible 83 submissions to the EPA about plans to keep doing more of the same for the next 20 years.
83!
Wow! This is fabulous! The overwhelming majority of responses were AGAINST the proposed plant upgrade that will double the capacity of the plant, using the same technology and methods which are already considered out of date.
In fact of the 78 people who answered the question of whether they support the plan as is, not one person said yes.
Thirteen said they would support it with changes and 65 were firmly against.
The people have spoken – now the question is whether Wannon Water will listen.
Because there were so many responses, the EPA will hold an online conference to hear more about the community concerns and ways they may be resolved.
(Details on when this will be held are yet to be announced.)
Thankyou to Colleen Hughson and all of the Good Will Nurdle Hunting team, the Beach Patrol 3280 team and the Clean Ocean Foundation for helping us to get our %#%@! together and have a say.
Wannon Water upgrade issues: The Terrier cheat sheet
Carol Altmann – The Terrier
The sexy Wannon Water sequel: Meet Dr Sam, the West Highland Water Scientist.
Dr Sam is here to help us have a say on the Warrnambool sewage treatment plant $40m upgrade which is actually not sexy, but boy, it’s important.
What happens next at that plant sets up what will happen off Thunder Point for the next 20 years.
It’s a big ask for us humble citizens to get our heads around the full proposal.
How can we possibly know whether it’s the best we can do for our beautiful ocean?
But we have until 1 July to express an opinion, no matter how humble.
In digesting this WW plan, Dr Sam and I have been able to take a bit of a short cut – and you can too.
I have been able to tap into scientific and environmental experts who are helping the Clean Ocean Foundation with its response.
They have shared some of their thoughts with me, to pass on to you.
This means that if you want to make a comment, you don’t have to feel overwhelmed and have some handy starting points.
What follows is a top 10 list of some of the very detailed concerns being compiled by the COF. At the end is a link to an extended mix of these tips.
We are giving the simple version here, but the message is clear: we need to invest in new ways of doing things, not just do more of the same for the next 20 years.
This is our chance to stand up for the sea.
Here is your Terrier 10-point cheat sheet:
1. Where does the sewage go if the treatment plant fails, or partially fails?
2. Risks to human health from exposure to the effluent both inside and outside the mixing zone via fishing, diving, snorkelling and rock pooling.
3. The phosphorus concentrations – largely from Warrnambool Cheese and Butter – are about 10 times higher than for a similar plant. This can lead to algal blooms.
4. Micro-plastics will still be able to make it through the screening process and into the sea.
5. There is no plan for effluent disinfection. Physical, or chemical disinfection will provide a much safer marine environment.
6. The amount of effluent discharged each day will grow from 16 megalitres to 26 mgl a day, which means more pollutants will also be discharged.
7. The upgrade doesn’t take into account ‘new’ pollutants and how these will be handled, such as micro plastics, organo-chlorines and pesticides.
8. There is no deep exploration of ways to reuse/recycle the wastewater or reduce the energy consumption of the upgraded plant.
9. There must be an upgrade of technology, not just an expansion of the existing systems.
10. Industries that create the vast majority of the waste should be paying more toward the plant upgrade to make it best practice and future proof.
Wannon Water sewage plant upgrade must reach for the stars
Betty Boop has nothing to do with Wannon Water and its treatment plant, but I am rolling out some stars to make sewage sexy.

Tonight I am rolling out the red carpet to make sewage sexy and effluent exotic, because we need to talk about the planned upgrade of the Wannon Water treatment plant.
This upgrade will service Warrnambool for the next 20 years.
I want to explain, as best I can, why before 1 July (when the chance for public comment closes) we need to ask for better from Wannon Water, to aim higher, and to stop using our beautiful ocean like a giant Maytag washing machine.
As it stands, Wannon Water plans to spend $40 million expanding the treatment works at the end of Elliot St, so it can double its capacity to eventually handle around 30 million litres of sewage a day by 2040.
This Wannon Water production should be a blockbuster starring the Brad Pitt of shit and the Betty Boop of poop and the Scarlett Johansson of industrial trade waste, except it isn’t even close.
It’s more of a B-grade movie starring faded stars of yesteryear.
That’s because the $40 million plan is the cheapest option and will not change the way our sewage is treated in the future from how it is treated now.

This means, in 2040, we will still be pouring millions of gallons of treated sewage/effluent into the ocean off Thunder Point using exactly the same treatment system as in 2020.
The COF is lobbying to have all waste water discharged to the ocean at a Class A+ standard by 2030 to reduce ocean pollution.
Warrnambool is not even at Class A now, and won’t be at Class A after the upgrade, let alone at A+.
Worse, our system often doesn’t work, as can been seen by what is called the “mixed liquor” (which sounds sexy, but is the revolting foamy brown stuff) which still turns up off Thunder Point.
What we should be aiming for by 2040 is clean, treated effluent that can be recycled and reused and doesn’t have to go into the ocean at all, but if it does, at least make sure it is not full of pollutants like phosphorous.
Right, how do I make phosphorous sexy?
Well, here is a photo of a very sexy Brad Pitt, followed by a sexy Wannon Water graph that shows that Warrnambool Cheese and Butter – the burgundy colour – producing a Pitt-load of phosphorous, nitrogen and ammonia that goes into our ocean:
Warrnambool Cheese and Butter is owned by the Canadian giant, Saputo, which turns over about $11 billion a year.
Perhaps we could ask Saputo to throw a few million toward helping us make it to the Hollywood A-list by making sure our ocean had the cleanest effluent possible?
Or maybe Saputo could spend a few million dollars improving the treatment of its own waste before it makes anywhere near Wannon Water and into the ocean?
Another of the problems from this dairy trade waste is it’s extremely salty, which means the effluent water cannot be reused easily without burning everything along the way.
I found it astonishing that of the millions of litres of waste water produced by the Warrnambool treatment plant – 15 million litres a day – only 60 million litres a year is reused, and only at the plant itself.
In the scheme of things, 60m litres a year is an eye dropper full and the rest goes into the sea to swirl around in nature’s Maytag: not a drop is recycled or reused outside of the Elliot St treatment plant.
Wannon Water says it has investigated reuse projects and also tried to find customers for recycled water, but without success, no doubt because of the high salt content among other things.
So we have a treatment plant within walking distance of the Warrnambool Golf Course* and the new Younger St housing estate, yet no recycled waste water from the treatment plant is being used at either. (*Clarification: water was diverted from Fonterra, before it reached the plant, for use on the golf course. Please see comment from Dave at the end of this story).
Good grief.
If this is “green” Warrnambool under the Warrnambool City Council 2040 plan, then we have a long, long way to go.
Of course it all comes down to dollars and who pays.
People, naturally, become nervous when Wannon Water talks about higher customer bills to cover the cost, but here is a photo of a beautiful Scarlett Johansson, under which we can see a beautiful graph showing the costs.
You will see that between the various options, it is really not that different – a range of 1.16% to 1.53%.
Is Wannon Water really that strapped for cash or ways to find it?
How bizarre that Lyndoch Living – a not-for-profit, community owned aged care home – can roll out out a $100 million masterplan, yet Wannon Water can only come up with $40 million for a major treatment plant expansion to service our city for the next 20 years.
Water treatment is complex, but I know we can do better than this, our kids deserve to inherit something better than this, and the Clean Ocean Foundation is right behind Warrnambool in its quest to ask for more.
The COF will appear in the blockbuster sequel to this story tomorrow night, offering us non-science-minded folk some starting tips for our submissions.
Because there were so many responses, the EPA will hold an online conference to hear more about the community concerns and ways they may be resolved.
