Water storage tanks are essential for providing clean, safe water at all times. They are also some of the most valuable assets in a utility system. Poorly maintained water tanks can create serious water quality issues, increase repair costs and lead to customer complaints.
At Covac, we specialise in tank maintenance, relining and repair services that protect water quality and extend the life of your tanks.
Can Tank Repairs Improve Water Quality?
Yes, tank repairs can significantly improve water quality. Repairs, such as relining, sealing leaks and removing corrosion, help prevent contaminants from entering the water supply. This ensures cleaner and safer water. Refurbishing also addresses issues that can negatively impact water quality. Three main problems can affect water quality when tanks are not properly maintained.
Chemical problems can occur when disinfectants in stored water change, affecting taste, odour and overall water quality.
Biological problems include microbial growth, nitrification and potential contamination from pathogens.
Physical problems such as sediment buildup create unsanitary conditions, while corrosion and structural damage can allow insects, wildlife and contaminants to enter. Cracks, holes and compromised coatings put the tank and water at risk.
How Often Should Water Tanks Be Inspected?
It is best to perform a thorough water tank inspection every six months and after major storms. Quick visual checks should be done more often to monitor for:
- Structural damage, leaks or corrosion
- Failing paint or coatings
- Sediment or unsanitary interior conditions
- Damaged vents, hatches or security issues
- Foundation deterioration or steel loss
Identifying problems early allows for planned repairs and avoids expensive emergency fixes.
How Often Should Water Tanks Be Cleaned?
Water tanks should be cleaned at least every year. If sediment is a known problem, cleaning should be done annually. The cleaning process includes draining the tank, scrubbing surfaces, removing buildup, disinfecting and rinsing. This ensures water quality and allows for thorough inspections.
Getting Started with Tank Maintenance
Start by walking around the outside of the tank. Check the condition of valves, the ability to isolate the tank, foundation cracks or erosion, leaks, rust, peeling coatings, ladders, screens, hatches, locks and any antennas. Use this information to create a schedule for inspections, cleaning and repairs.
Professional tank maintenance is essential. Make sure any contractors you hire have experience and follow safety protocols, especially for confined space work. Once you receive an inspection report, review it with your team to determine what needs immediate attention, what can wait and how coatings or repairs can be extended. If you’re managing multiple tanks, prioritise repairs based on age, condition and water quality risks.
The Benefits of Regular Water Tank Maintenance
Investing in tank maintenance helps avoid costly emergency repairs, protects public health and builds trust in your water system. Plan for full inspections every six months or after major weather events, conduct frequent visual checks and clean tanks every year.
