  • Yes, we offer comprehensive compliance reports and inspections for water tanks to ensure regulatory adherence. Our team is well-versed in local, regional, and national regulations governing water tank construction, maintenance, and safety.

We base our recommendations on factors such as the amount of sediment removed from the tank, tank usage, and overall condition of the tank.

  • Our cleaning and disinfection process involves draining the tank, removing sediment and debris, scrubbing the interior surfaces, and disinfecting with industry-approved solutions. We ensure thorough cleaning while adhering to safety standards and regulatory guidelines.

  • Yes, we do! Fitting out a concrete water tank with a liner offers several advantages. It provides an additional layer of protection against corrosion, extending the lifespan of the tank. Liners also help to prevent water seepage and leakage, reducing the risk of structural damage. Moreover, liners can improve the water quality by creating a smooth and non-porous surface that is resistant to bacterial growth and sediment accumulation.

  • Yes, we provide underwater drone inspection services specifically designed for water tanks, reservoirs, and other submerged structures.

  • Underwater drone inspections offer several advantages. They eliminate the need for human divers, reducing safety risks and costs associated with traditional underwater inspections. The drones can access hard-to-reach areas, providing a comprehensive visual assessment of the tank's condition. The real-time video footage and data collected by the drones enable quick and accurate evaluation, helping identify issues promptly.

  • Yes! We are specialists in this area. We can attend to an emergency situation, make a temporary or, if possible, permanent repair, and then offer a quick turnaround solution for a replacement liner. Our experienced team will assess the condition of your existing liner and recommend the appropriate replacement option based on your specific requirements.

  • The lifespan of a newly installed liner can vary depending on factors such as material quality, usage, maintenance, and environmental conditions. Generally, well-maintained liners can last anywhere from 10 to 20 years or more, providing reliable protection for your water tank.

  • Yes, we offer professional services for the deconstruction and removal of old water tanks. Our team is equipped with the necessary tools and expertise to safely dismantle and dispose of the tank and its components.

  • There are several benefits to deconstructing and removing old water tanks. Firstly, it allows you to clear up space for potential new construction or repurposing of the area. Secondly, old tanks may pose safety risks due to structural deterioration, such as leaks, rust, or weakened supports. Removing them mitigates these risks and ensures a safer environment. Lastly, it eliminates the ongoing maintenance and repair costs associated with maintaining an aging and inefficient water tank.

I just wanted to say Thank You to Trent and his team for not only their expertise but their workmanship on completing our modification and rectification works. We had originally planned on fixing up some small leaks, replacing liners and replacing damaged parts, however, after consideration and discussions with Trent, we agreed upon making structural upgrades to our tank and we could not be happier with the end results. I will continue to use Trent and his team for any future works, and highly recommend using MAC Tanks.

Trent was a champion to deal with right from the first phone call we had around my tank build. He was extremely knowledgeable and was not deterred with the remote location I asked him to assemble the tank at. I would have no reservations around utilising Trent again on any future tank builds or from recommending him to anybody who wants quality work on their own tank build.

Trent has always gone above and beyond his scope of works and always left the tanks here at Chifley Tower in an exceptional condition. I would highly recommend him for any tank works in any condition

I had 2 x 0.5 meg panel tanks relined and new roof sheets installed. Great communication and completed work schedules within specified timeline. No delays. No issues. Perfect result!
At our shopping centre, the retention tanks were in a bad state and needed urgent attention. Trent and his team did a great job with fixing the defects and cleaning the tanks. I would highly recommend MAC Tanks. Regards Joe
