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 is a legend! He really knows his stuff when it comes to greywater systems, composting toilets, sustainability, environmental science, and more. Not to mention he is so generous with his time and energy. His approach is very down to earth, he's open to answering all sorts of questions and you can feel that Anthony really cares about helping people and doing right by the Earth. I've consulted with him many times with advice about greywater and composting toilets especially, when I was moving into my tiny house. Anthony is also a really lovely guy and I wouldn't hesitate recommending him for all things greywater, poo talk and related areas!

Anthony is a minefield of information and was able to suggest solutions for 3 different composting toilet set up we require. His whiteboard sketches really helped the 3 of us, all firing questions at Anthony ( a builder, caretaken and me, farm manager) clearly understand the concept much more accurately. I highly recommend him as a consultant for anyone confused about all the options concerning compost toilets.
