Why choose a consultation with Anthony?

Our customers choose to work with Anthony for many reasons, here’s just a few of them.
  • Expert advice – Anthony’s a qualified Environmental Engineer, specialising in off-grid wastewater management and toilet options – with over 10 years’ experience in the industry.
  • Impartial advice – we’re not here to sell you products. Anthony knows what options are available across Australia and can advise you on what setup will work best for you.
  • Save money – avoid costly mistakes by getting the right set-up for your needs.
  • Save time – wading through the muddy waters of wastewater management and composting toilet options etc. can be difficult and time-consuming if you go it alone.
  • Easy to follow advice – Anthony is a master at taking complex systems and procedures and making them easy to digest and understand.
The best wastewater setup for your needs

When it comes to wastewater management, there is no “one size fits all” – and it pays to know your options. Managing waste and wastewater is a critical component of any off-grid/unsewered project. A system that compliments your existing site/soil conditions and meets your needs and budget can ensure your setup works well for many years without expensive ongoing maintenance costs.

How do the consultations work?

Generally, we do things via a Google Meet (video call). In this video call you can explain your situation, share photos and/or site plans etc., and we can discuss ideas and potential solutions. Anthony also often uses a digital whiteboard to visually explain ideas and/or more detailed design components of a particular situation/solution.

Essentially, you let us know what you need, and we’ll provide the advice and/or service to get you there!

Your needs

Most of our customers fit into one of the two situations below.

Option 1 – Onsite wastewater 101

If you’ve got a property or project in mind and are wondering about your options, we can point you in the right direction. We would typically start by discussing your project and what you’re trying to achieve. From here, we can start looking into what factors need to be considered, including site and soil conditions, local government regulations, budget and the pros and cons of potential options. Ultimately, it’s a balancing act between your wants and needs as the homeowner (or business operator), the site and soil conditions and the boxes that might need to be ticked for approvals.

Option 2 – Specific needs/hurdles/ questions

If it’s a question that has anything to do with wastewater, Anthony can probably help! Here’s a sample of some of the areas Anthony can advise on.

  • Hurdles with local government applications
  • An existing system that needs fixing/changing/upgrading
  • Troubleshooting your wastewater setup
  • Advice on different systems available on the market (without the sales B.S.!)
  • Advice on DIY systems
  • Systems to suit larger-scale operations (tourism ventures etc.)
  • Composting toilets
  • Septic system
  • Greywater setups
  • Worm based “Vermiculture” systems
  • Reed beds
  • Aerated Wastewater Treatment Systems (AWTS)
  • And more!

Anthony was a great source of information and knowledge I had no idea how to go about implementing a grey water system for our home but after the consult I feel very confident about moving forward and being able to decrease our reliance on town water. Highly recommended Anthony and all his years of experience in the field.

Absolutely fantastic consult that I could not recommend more highly. Anthony has an incredible wealth of knowledge but is able to distill it into accessible info that's really easy to follow. In our case, his advice is going to save us money and give us a better outcome than if we'd carried on without his advice.

I had a consultation with Anthony from Water Wally because of our continuing problems with our composting toilet over the past 9 weeks in our tiny home We've had ongoing problems including flies, a strong ammonia smell when it rains and lack of composting in the chamber. Anthony was extremely thorough collecting information regarding location and setup prior to making any recommendations... In much the same way a doctor collects all the symptoms and test results before making a diagnosis. I took the phone outside so he could physically see the set up too. Anthony provided me with a number of improvements we could make to the setup and also dispelled some inaccuracies we had been told. I had been unable to get resolution through the company that sold the WC. We also talked about whether there would have been a better option for us given our location and it appears there would have been.... SO I urge anyone embarking on the tiny house journey to have a consultation with Anthony PRIOR to committing to any solution. There may be different/better answers for certain situations. For those who think that $250 is expensive for a consultation.... I suggest you consider the cost of making the wrong decision. It appears we could have got a much better solution for half the expense of the composting WC and greywater system. It is a tiny expense in the overall cost of building your home and I can assure you that it is one of the most impactful on your state of mind. I highly recommend Anthony as a specialist in this area... he has many years practical experience dealing with all the issues and I regret missing his presentation at the Toowoomba tiny home show.

We bought a composting toilet from Anthony of Water Wally. It's great and works well in the studio. I want to buy another for our RV but I can't reach anyone. Lots of messages and a contact form in the website and nothing back. Frustrating.

Great advice that and took into account our specific needs and situation. We are in the planning stages and needed a reality check on what solutions we should be looking at. Anthony gave low key, practical advice and clearly has great knowledge. He was also good at explaining technical things for the uneducated but enthusiastic. Would recommend for a consultation.
