1. UV-Guard Australia
Website: http://www.uvguard.com/
Address: 18/7 Packard Avenue, Castle Hill
Contact: 02 9139 9970
Hours: Monday-Friday, 8:30 AM – 5:00 PM
UV-Guard Australia specialises in powerful ultraviolet disinfection systems that remove harmful waterborne pathogens without harsh chemicals. This makes them a practical option for treating drinking water tanks on rural properties.
One client we spoke with installed their residential system and said they noticed a major improvement in their water supply.
They also offer tailored treatment setups to suit specific bore or river water sources. This provides effective purification while preserving the natural taste of your tap water.
However, they focus almost entirely on ultraviolet equipment, so you’ll need to look elsewhere for a complete reverse osmosis system.
You may also need to hire a separate plumber to handle any pipe integration since they don’t do that.

I stuffed up the installation, UVguard were great to deal with in helping me correct it and easy to contact. Good product, looks good too. Watch their YouTube video before installing it if you’re doing it yourself, and it’s very easy that way. Recommend. Thank you!

2. Filpure
Website: https://www.filpure.com.au/
Address: 28 Nelson Street, Fairfield
Contact: 02 9724 2177
Hours: Monday-Friday, 8:00 AM – 5:00 PM
Filpure delivers practical water filtration systems designed specifically to handle the unique quality variations found across Sydney. Their standout feature is tailored setups ranging from simple single-tap filters to expansive whole-house configurations.
This flexibility allows you to find an exact match for your daily usage and demand. Their premium water treatment solutions can also effectively reduce chlorine and annoying sediments for noticeably cleaner drinking water.
Plus, they stock a huge variety of spare parts to keep your equipment running smoothly over time.
A minor drawback is that they offer free shipping only on selected products, so you may face extra delivery fees depending on your final order.
Despite that minor cost, they provide some of the most consistent water treatment services available in the state today.
Great service
I researched filter systems high and low and this company and their product came highly recommended..I have never regretted it. Water tastes so clean and crisp! They really went above and beyond helping me choose and fit to our kitchen to minimise the space taken up by the unit. We have been with this company for many years now and they have always delivered a great service, on time, punctual and knowledgeable.

Satisfied customer
I am happy with the filtration system and also recommended to my parents. They service every 6 months and call to remind of the upcoming service. Initially had a problem with our black tap, which-also was purchased from them. The tap pealed, but they gave me a new tap free. This time I got stainless steel.

3. Aerofloat Australia
Website: http://www.aerofloat.com.au/
Address: 36 Cawarra Road, Caringbah
Contact: 02 9544 1449
Hours: Monday-Friday, 8:00 AM – 4:00 PM
Aerofloat Australia designs and builds advanced wastewater plants for complex industrial and municipal needs. Their main strength is creating simple, durable systems built for long-term reliability and regulatory compliance.
They also handle the full integration process, helping your new setup run efficiently from day one.
Plus, their commercial water treatment systems cover everything from basic clarification to advanced membrane filtration, so they can handle a range of needs.
However, their focus is mainly on large-scale industrial projects. That means they aren’t the right fit if you only need a small household filter installed.
For larger commercial water treatment projects, though, their experienced engineering team offers a specialised service.

Address: Unit 28, 17 Lorraine Street, Peakhurst
Contact: 02 9584 3687
Hours: Monday-Friday, 8:00 AM – 4:30 PM
MAK Water provides operational support and remote monitoring for complex industrial water treatment facilities. Their service teams can take over the daily management of your plant, with flexible operators available on-site when needed.
They also supply essential reagents and replacement parts quickly, helping keep your system running safely and smoothly.
For the best results, you can even hire a reliable drain cleaning service to maintain good pipe flow alongside their commercial water treatment programs.
Unfortunately, they focus strictly on commercial and municipal clients. They don’t cater to residential customers looking for basic drinking water solutions.
Still, if you’re managing a large industrial water treatment facility, their support keeps things practical and dependable.

Plus, the team can handle regular filter replacements to keep your system working properly year-round.
But remember, they operate as a franchise, so strict head office rules can sometimes limit how much they can customise their solutions.
Even so, their focus on rural tank purification can give homeowners greater peace of mind.
Highly recommend
We have had Glen supporting us for three years now and we couldn’t be happier. Before we met him we struggled with filthy tanks and poor quality water and weren’t sure what the answer was. We now have clear tanks that years post their clean you can see to the bottom of the tank and a filtration system that ensures we have the best quality and tasting water. In fact we can’t drink water anywhere else. Highly recommend him for his technical skills, knowledge, communication style and genuine care.

Very happy customer
Great service and quality products at a competetive price. I have used Glen and his team for my water tank cleaning before, and this time I also had them instal a filtration and ozone system, which I’m very happy with.
