From Mines to Hospitals: What Every Sector Gets Wrong About Tank Maintenance

Water tanks are often the quiet workhorses of infrastructure, out of sight, out of mind, until something goes wrong. Whether you manage a remote mine, a busy hospital, a processing plant, or a public water system, storage tanks play a critical role in daily operations.

But here’s the catch: most industries approach tank maintenance with a one-size-fits-all mindset. And that’s where things go wrong.

In this article, we’ll explore the most common mistakes made in four key sectors and how Pacific Water Tanks helps organisations avoid the costly consequences.

Mining: The Danger of Delayed Inspection

Mistake: Running tanks to failure before acting

Mining operations depend heavily on bulk water storage for dust suppression, processing, firefighting, and potable supply. But in many sites, especially remote or FIFO locations, maintenance is reactive rather than proactive.

Tanks often go years without inspection, only being addressed once visible damage or a leak occurs. By then, corrosion, sediment build-up, or structural fatigue has often spread.

Risk: Shutdowns, water contamination, and high emergency costs

Hospitals are highly regulated environments. Poor tank hygiene can lead to contamination, disease spread, and regulatory fines. It’s not just a maintenance issue, it’s a patient safety one.What works instead, Pacific Water Tanks offers:

RPVC liner installation to preserve tank hygiene
AS1851-2012 inspections for fire water systems
Scheduled cleaning, maintenance, and recoating
Solutions tailored for public and private healthcare buildings

They’ve refurbished tanks across hospital networks to ensure a clean, compliant, and uninterrupted supply.

Industrial & Commercial: Overlooking Corrosive Environments

Mistake: Underestimating chemical exposure

Industrial and commercial sites like food processing plants, manufacturing facilities, and chemical storage depots often underestimate the corrosive nature of their operations.
Even small chemical vapours, temperature swings, or process by-products can deteriorate tank coatings or liners. Many sites assume their tanks are built to last “forever,” but steel only lasts without corrosion if it’s protected.

Risk: Tank failure, product loss, environmental impact

Without regular maintenance, you risk not just structural failure but contaminated outputs, safety incidents, and potential regulatory violations from leakages.

What works instead: Pacific Water Tanks provides:

Custom coating systems for harsh chemical or thermal environments
Structural upgrades to prevent microbiologically influenced corrosion (MIC).
Tank retrofits with modular GRP or stainless steel panels

They’ve delivered solutions for chemical facilities, food production plants, and large-scale commercial sites, focusing on asset longevity and safety compliance.

Public Sector: The Maintenance Myth

Mistake: Relying on outdated assets and limited resources

Councils, regional governments, and water authorities often oversee ageing public infrastructures, tanks 30+ years old. Yet with limited budgets, maintenance is often reactive.

There’s also a lack of awareness about current standards (like AS2304 for fire tanks), and many older tanks no longer meet compliance without anyone realising it.

Leaks or dampness around the base

Moisture collecting around the base of the tank, especially near seams or fittings, often signals a breach. Corrosion commonly starts at connection points or where the tank meets the foundation slab areas prone to condensation, sediment accumulation, and pressure stress.

Regular inspections of these critical zones can reveal early signs of failure.

Risk: Service disruption and public health concerns

If a potable water tank fails, a community may be left without safe drinking water. If a fire tank is non-compliant, it may put emergency response at risk. Either way, it can damage public trust and lead to legal issues.

What works instead, Pacific Water Tanks supports public sector clients with:

Compliant inspections, repairs, and fire tank upgrades
RPVC liner retrofits for drinking water tanks
Design and construct services for new tank systems
Project coordination for regional and government contracts.

Projects include town reservoir upgrades in Bamaga, New Mapoon, and other regional communities in partnership with state authorities.

What These Sectors All Get Wrong

Despite their differences, mining, healthcare, industrial and public sectors often make the same critical errors:

Common Mistake

Delaying inspections

Ignoring liner degradation

Treating tanks as 'set and forget'

Skipping compliance updates

Using the wrong materials

Consequence

Hidden corrosion leads to costly failures

Contamination or leakage risk

Shortens asset lifespan

Fines, shutdowns, or legal risk

Premature corrosion in aggressive settings

What You Should Be Doing Instead

Here’s a simple checklist to get tank maintenance right, no matter your industry:

Task

Professional inspection

Internal liner check

Cleaning and sediment removal

Recoating or relining

Compliance review

Frequency

Annually (or per AS1851)

Every 2–3 years

Annually or bi-annually

As needed

Ongoing

Why It Matters

Detect corrosion or wall thinning early

Prevent chemical degradation and leaks

Maintain water quality and tank health

Extend lifespan and restore integrity

Stay aligned with AS1851 & AS2304 standards

Did You Know?

Over 60% of tank failures in Australia are due to corrosion-related issues, most of which could have been prevented with regular inspections and protective linings.
Fire storage tanks must comply with AS1851-2012 and AS2304 standards. Many older tanks still in use today do not meet these requirements, exposing facilities to legal and insurance risks.
Microbiologically Influenced Corrosion (MIC) can destroy internal tank walls from the inside out, and it’s almost impossible to detect without specialised inspection tools like UAV or ROV drones.
Pacific Water Tanks has worked on water storage assets for mines, hospitals, food plants, councils, and more, applying sector-specific strategies that extend tank life by 10+ years
