How Water Tank Maintenance Works

Every effective tank maintenance program starts with a detailed tank inspection. The inspection identifies corrosion, leaks, structural damage, sediment build-up, and worn components.

The inspection findings determine the maintenance work required to restore safe and reliable operation. Our technicians complete the necessary cleaning, repairs, testing, and preventative maintenance. Every inspection and maintenance activity is documented in a detailed service report.

This provides a clear maintenance history, supports compliance, and helps plan future servicing.    

Professional Tank Cleaning and Maintenance

Raven Tanks provides complete maintenance solutions that protect tank condition, water quality, and long-term system performance.    

Tank Draining and Sludge Removal

We drain the tank and remove sediment, sludge, and debris collected across the tank floor.   

Interior Surface Cleaning

Our technicians scrub internal walls and surfaces using suitable equipment and safe cleaning products.  

Tank Sanitisation

We rinse and disinfect internal surfaces using an approved diluted solution before safely refilling the tank.  

Leak and Corrosion Checks

We inspect the tank for leaks, corrosion, rust, cracks, and other signs of deterioration.  

Water Level Monitoring

e install, service, and maintain tank level indicators to provide accurate and reliable water level monitoring for all types of water storage tanks. 

Valves and Component Checks

We inspect inlet filters, outlets, valves, fittings, and other components to confirm reliable operation.  

Water Tank Condition Checks

Regular condition checks help identify problems before they become major repairs. Raven Tanks inspects every tank to identify damage early and support reliable long-term performance. 

Regular condition checks help extend tank life, reduce the risk of unexpected failures, and identify when microbiologically influenced corrosion solutions may be required.

Roof and Tank Component Maintenance

Regular maintenance of the roof and tank components helps protect water quality and maintain reliable operation.  

Routine roof and component maintenance helps extend tank life, reduce the risk of unexpected failures, and support timely tank roof replacement when needed.

Sediment and Debris Removal

Over time, sediment, sludge, and other contaminants can accumulate inside water tanks, affecting water quality and reducing storage efficiency. Regular cleaning helps maintain a cleaner, safer, and more reliable water storage system.   

Sediment Removal

We remove built-up sediment from the tank floor to help maintain storage capacity and reduce the risk of contamination.  

Sludge and Organic Matter

We remove sludge, leaves, algae, and other organic material that can accumulate over time and affect water quality.  

Debris Clean-Out

We clear dirt, debris, and foreign objects from the tank to support efficient operation and long-term performance.   

Water Tank Cleaning for Every Application

Raven Tanks provides professional tank cleaning services for a wide range of water storage systems across commercial, industrial, and municipal applications.   

Read our water tank cleaning guide to learn how regular cleaning helps maintain water quality and extend tank life.   

Water Tank Cleaning with ROV

Water tank cleaning with ROV technology provides an efficient way to remove sediment and debris while minimising downtime and operational disruption. We use ROV inspection technology to safely assess water tanks and support effective maintenance planning.   

Cleaning Without Draining

ROV technology allows tanks to be cleaned without draining, helping maintain water supply throughout the maintenance process.  

Safe Access

Using a remotely operated vehicle reduces the need for confined space entry while reaching difficult areas inside the tank. 

Efficient Cleaning for Large Tanks

ROV cleaning is ideal for commercial, industrial, and fire water tanks where traditional cleaning methods are less practical.  

Recommended Water Tank Maintenance Schedule

Regular maintenance helps identify minor issues early and keeps your water storage system operating reliably.  

Maintenance TaskRecommended Frequency
General Tank Condition CheckEvery 6–12 months
Roof, Hatch & Vent MaintenanceEvery 6–12 months
