e-Flush’s friendly ingredients won’t damage the bacterial balance in your ATU (unlike bleach-based cleaners) and it’s designed with ATU’s in mind. e-Flush’s job is to digest organic waste at the source of odour, replacing bad bacteria with beneficial good microbes. 

These microbes penetrate porous surfaces and establish effective, self-renewing biofilms deep inside inaccessible plumbing lines. The microbes work to clean, refresh, eliminate organic waste build up and deodorise by successfully destroying the source of the unpleasant odours. Best of all, it’s pet, people and planet friendly!

Tech Talk - Decoding the QMR

Roslyn McKay

Hi! If we haven’t met, I’m Robyn Haines, co-owner of Ecowater Services with Warren Haines. 

Over the next few issues of our e-news I am going to put the magnifying glass on some important aspects of ATU ownership. In this edition, we’ll be looking at planning ahead and how you can minimise “bill shock” when it comes to some of the costs associated with maintaining your ATU. 

Planning ahead is about the ongoing maintenance of a home or property. In the seven years I have been talking with ATU owners, I can’t count the number of times that the need for a pump out has been bad timing financially or came as a complete surprise.  

So to help you be prepared, I strongly recommend you take regular notice ofITEM 11 Anaerobic Chamber on your Quarterly Maintenance Report (QMR).  This is where you will find the information you need to plan ahead for the considerable and unavoidable cost of a pump out.

Kitchen and laundry appliances, walls with paint, floors and other fixtures and finishes all, at some point, need either proactive or remedial care.  Same goes for your ATU system - it really is just another household appliance. And it actually is inevitable - one day your ATU will need to have all the solid waste removed, or in other words - be “pumped out.”

While the measure of fullness of the anaerobic chamber is not a guess by your technician, what they see in your ATU is strongly influenced by the “cultural practices” of the residents. In other words, what goes down the drain or is flushed away can drastically change what can be “seen” and how the ATU “behaves”.

 If your technician suspects that your system is getting full they will then use a “sludge judge” to accurately measure the percentage of fullness - i.e. the amount of solid matter in your ATU.  As an ATU gets “full” the air pump and water pump will be under a heavier load. Failure to schedule a pump out when the ATU is full can cause costly damage not just to your pumps but also the infrastructure of your ATU.

The minimum that you should plan for is $1400 (based on an ATU capacity of 6500L). Ecowater Services only recommend experienced septic truck operators. Use caution if you are getting quotes - discuss their experience and the volume they are quoting you on. Expensive damage can be incurred by using inferior service providers.  

If you have any questions about what has been reported on your QMR please don’t hesitate to contact us in the office or ask your technician when he is on site.  If you would like to discuss “pre-paying” to prepare for the cost of a pump out please contact our friendly Support Team on 08 9248 9440.

In the next issue of e-news I’ll go through some of the other terminology that your technician uses in ITEM 11 on the QMR.

Thanks for taking the time to educate yourself about your ATU.

Robyn :)

The Good, The Bad & The Ugly

Roslyn McKay

If you have an Aerobic Treatment Unit (ATU) at your place, there are some specific things happening down your drain. Read on to learn a little more about how your ATU breaks down waste and how to keep it happy. Let's face it... no-one wants to deal with a stinky blow-out.

Ever wonder what happens to everything that goes down the drain? How to keep Gordon the good guy happy and Barry the Bad guy away? How to stop The Ugly Truth from rearing its even uglier head? Read on on to better understand what happens when you turn on the tap, flush and pull the plug.



Say hi to Gordon. Gordon the Good Bacteria is here to save the day. He’s working bacterial miracles down your drain. Fighting the bad guys and keeping things smelling sweet.

Cleaning products from the Enviroplus range give him pro-biotic superpowers. Ignored and abused, he loses his will to live and gets defeated by Barry, the Bad Bacteria.


Barry is your frenemy*, smells great, says all the right things, behaves perfectly in public...but behind your back he’s working hard to make life miserable in your ATU and make life miserable for you.

You might know him as oxygen bleach, detergent, baby wipes, fats and oils including some essential oils. It's vital to know what your pouring down your sink and how it's going to affect the biology in you ATU. 

Click through to our comprehensive list of what NOT to put down your drains.

*(A frenemy is a friend that is really an enemy).


The Ugly Truth is just that. The ugly, inconvenient and smelly reality of things gone wrong in your ATU. It’s making it’s presence felt - all through the house. Let’s face it, no-one wants to meet this guy. Ever.

So how do you keep this Baddie away? Firstly, by keeping your Ecowater Services quarterly maintenance up-to-date. Secondly, use household cleaning products and toilet paper that supercharge the good bacteria working hard in your ATU.

Ecowater Services uses and recommends Enviroplus. This small change can make a really big difference to the health of your ATU and save you money in the long-term.
