The Water Wally Story

There’s no planet B. Let’s take care of planet A.

At its core, Water Wally is about making a positive contribution to the one and only planet we have. Our particular patch of expertise? Sustainable wastewater management.

Founded by environmental engineer Anthony “Smitho” Smith, Water Wally brings together hands-on experience, technical knowledge and a passion for helping people understand their options.

From backyards to BHP, we’ve worked with homeowners, tourism operators, community organisations and mining companies to find practical ways to manage wastewater. Our work takes us from suburban gardens to remote, off-grid locations, helping people conserve water, reduce waste and make better use of the resources they have.

Composting toilets, greywater recycling, septic systems, natural treatment processes—there are plenty of possibilities. We help make sense of them, matching solutions to the people who use them and the places they need to work.

Our Mission

We’re here to simplify things.

Through practical advice, assessments, design and education, we help individuals and organisations manage wastewater safely and responsibly, with an understanding of how their systems work.

We consider the whole picture: the site, the soil, the people, the approvals and what it will take to keep a system working over the long term. We have a particular interest in natural and passive approaches, and in turning waste into a resource wherever practical.

Often, the simplest and least expensive solutions are also the most practical and sustainable ones.

Anthony (Smitho) Smith

Environmental engineer, wastewater educator and the original Water Wally.

After completing a degree in Environmental Engineering, Anthony travelled around Australia, living and working on remote, self-sufficient properties. Water was often in short supply, and composting toilets and greywater reuse were part of everyday life.

Those experiences stuck. A waterwise landscaping business followed, then a growing interest in what happened to water after it went down the drain. That eventually became Water Wally.

Over the past 15-plus years, Anthony has helped hundreds of homeowners, tourism operators, businesses and community organisations work through their wastewater needs. His projects have ranged from tiny homes and eco-accommodation to remote installations in the Kimberley and Pilbara.

He’s been involved in assessing sites and soils, designing systems, navigating approvals, installing equipment and keeping it working. That practical experience shapes his advice: a system needs to suit the site and be manageable for the people looking after it.

Anthony enjoys sharing what he’s learned. He’s spoken to thousands of people at Tiny Homes Expo and Off Grid Living events, presented to community and industry groups, and contributed to podcasts and publications. He is an Industry Advisor on Wastewater for the Australian Tiny House Association and authored its Wastewater for Tiny Homes Guidelines.

Talks and Presentations

Wastewater might not sound like a crowd favourite, but Smitho enjoys getting people talking about the things we usually flush away.

He’s presented at Tiny Homes Expos, off-grid living festivals, the AWA International Wastewater Conference, permaculture design courses and community events.

From composting toilets and greywater recycling to septic systems and off-grid setups, Smitho explains how low-tech wastewater solutions work in language people can understand. His talks draw on hands-on experience, with plenty of practical examples and time for questions.

The aim is simple: take some of the mystery out of wastewater and make sustainable solutions accessible to everyone.

Anthony is a good operator and knows all the facts to negotiate solutions with the authorities. Authorities that don't always read their own policies... 🤔😏 Highly recommended

With so many options and companies claiming to be the best, Water Wally steered me through all that and helped me decide on the best way to sort my needs. Well worth the time and investment. Highly recommend.

Used the Water Wally for a 1 hour consultation to get advice on composting toilets and grey water systems specific to a modular build. Anthony was great to chat to, he was full of knowledge and expert advice. What was invaluable was his advice on how to work with our shire to get planning approval and what modifications we need to organise with the modular company to include in the building process. He has some great resources including the Grey to Green which I would highly recommend to anyone looking for more information on grey water systems. Thanks again for you time and expertise Anthony!

Great to chat to Anthony - he quickly clarified the process of waste water management, so that I could move forward in planning my build. He's up to speed with council approvals, and so I didn't have to waste time further researching the matter. All questions answered! Anthony made my decision easier, and I am most grateful for his advice.

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.

Anthony was extremely helpful in stepping me through the waste water options for our tiny home. His experience and expertise was invaluable in giving me information to make decisions going forward. I'd definitely recommend a consult.

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.
