Professional Water Tank Maintenance Services
Tank Maintenance
Arranging preventative maintenance to be regularly carried out on your tanks is critical to ensuring your liquid storage systems remain safe and are in optimum working order.
Although primarily precautionary, having scheduled maintenance performed on your tanks by industry leaders significantly reduces the risks of leaks, equipment faults and future system failures.
With increasing emphasis being placed upon standards, legislation and responsibilities surrounding our industry, understanding tank ownership requirements has never been more important.

Routine Maintenance – Inspections, Cleaning & Repairs
Raven Tanks inspect, clean and maintain all elements of your potable water tanks, fire tanks and non-potable liquid containment systems in accordance with Australia’s industry standards.
Our team will assess your entire tank unit determining the most appropriate course of action regarding any detected leaks, faults or outdated equipment proving potentially hazardous.
We also carry out high-pressure surface cleaning procedures helping manage corrosion and keep your tanks and their contents in exceptional condition.
Signage
We supply and install all tank signage as per national compliance requirements.
Fire tank systems must display the following colour-coded signs in their respective dimensions, with Raven Tanks capable of affixing each:
- Capacity signage
- Contents signage
- Potable/Non-potable water signage (Do Not Drink)
- Level Indicator signage
- Warning and locational indicators
Tank Fixtures & Components
Repairs are often the next best maintenance alternative to fully replacing internal tank parts such as panels, ladders and connective equipment.
Restoring a tank’s fittings ensures the system operates in a satisfactory condition, perfect for meeting mandatory compliance criteria.
Revamping the existing hardware is generally less expensive while still offering remarkable, remodelled performance.
Level Indicators
Different tank types require different sorts of level indicators. We can custom-supply panel tank level indicators to suit a number of industry-specific systems and applications.
These use sensory technology to identify highly accurate contents levels and is essential to maximising your tank’s operational efficiency. Eventually, indicative sensors deteriorate and fail to correctly read the substances contained in your tanks.
Level indicator maintenance and replacement are the more effective methods of avoiding the inconvenience of a major shutdown caused by a total malfunction.

Client Questions – Our Answers
We know our clients often have important questions before starting a project. Here are clear answers to help you make informed decisions with confidence.
Signs your water tank needs cleaning include unpleasant odours, discoloured water, visible sediment, or reduced water flow. Regular inspections every 6–12 months help catch issues early and prevent contamination.
The best method includes draining the tank, removing sludge manually or with pressure washers, disinfecting with a suitable chemical (like chlorine solution), and rinsing thoroughly. Always follow safety protocols, especially in confined spaces.
Domestic water tanks should be cleaned every 6 to 12 months. Commercial or rainwater tanks may require more frequent maintenance depending on usage, location, and exposure to contaminants.
To maintain a stainless steel (SS) water tank effectively, it’s important to inspect it regularly for any signs of corrosion or structural damage. Cleaning should be done at least twice a year to remove sediment or biofilm buildup. Using a secure tank cover helps keep out insects, leaves, and other contaminants.
