Reinforced vs. Monofilament Tank Liners: There's A Clear Winner for Water Quality and Longevity!

When you depend on a steel water tank as your main daily water supply, every drop counts, and not just for its quantity but for its purity.

Something many don’t realise is that your choice of tank liner matters and there’s one type of liner that promises to safeguard your water’s hygiene and preserve the tank’s lifespan better. It’s a small detail that has a significant impact, so when choosing between reinforced and monofilament liners for your steel water tank you’ll want the one that’s best for water quality, tank longevity, and overall value.

Whether you’re managing a large rural property or overseeing commercial water storage, understanding the critical differences between these liners can be key to cleaner water and longer-lasting tanks.

As a leading supplier of water tanks in NSW and SE QLD, we’ve made a clear choice: monofilament liners.

But why?

In this article we’ll explain how monofilament tank liners are becoming the go-to in water storage, delivering superior flexibility, durability, and water purity that leave traditional reinforced liners behind.

Why Tank Liners are Far More Than Just a Barrier

Before comparing the two, it’s important to understand the important role tank liners play and it’s a multifaceted one.

Corrosion Prevention:

They protect the steel tank from water contact, preventing rust and prolonging its life.

Water Purity:

A quality liner ensures the stored water remains uncontaminated by metal or other external elements.

Structural Support:

While the steel provides the tank’s main structure, the liner contributes to the overall strength and integrity, especially during water level fluctuations.

Both monofilament and reinforced are high-quality tank liners, there are considerable differences. When comparing the two types, there are three main factors to keep in mind: the material, its flexibility, and purity.

The Key Features of Monofilament and Reinforced Liners

As the name suggests, reinforced liners are made up of multiple layers of material – a polyethylene base plus reinforcement mesh coated with PVC or similar substances. Monofilament liners, on the other hand, are composed of a single layer of polyethylene that’s highly resistant to UV radiation and chemical exposure. Here are the distinguishing features of each:

Monofilament Liners

  • Made from a single, continuous filament of material giving a smooth, uniform surface
  • Highly flexible and adaptable
  • No risk of reduced water purity through delamination (layers separating)

Reinforced Liners

  • Constructed with a mesh or scrim layer between material layers
  • Constructed with a mesh or scrim layer between material layers
  • Risk of delamination over time, which can compromise water quality

Why Monofilament Liners Take the Lead

Based on the key differences mentioned above, monofilament liners offer several advantages that make them a clear winner for water quality and tank longevity:

Unmatched Flexibility and Strength

Monofilament tank liners are made of low-density polyethylene (HDPE), a material chosen for its superior flexibility and chemical resistance. Unlike PVC, which requires chemical additives to remain flexible, HDPE maintains its strength over time without leaching harmful chemicals into the water, making it ideal for long-term water storage.
Liners, like the Enviro Liner 6000HD, bring a combination of flexibility and strength that’s set high standards and beyond the technical specifications; there are some real-world advantages:

Adaptability:

The liner accommodates tank movements as it expands and contracts with temperature changes and fluctuating water levels, preventing cracking or tearing.

Even Stress Distribution:

Unlike reinforced liners, which can develop weak spots at the mesh interface, monofilament liners distribute stress evenly, minimising wear and tear.

Customised Tank Linings: The Right Fit Every Time

One size doesn’t fit all in water storage, so the use of monofilament liners allows for:

Precise Customisation:

Liners can be tailored to perfectly fit tanks of various shapes and sizes.

Wrinkle-Free Installation:

The smooth surface means no creases where bacteria or sediment can hide, keeping water cleaner for longer.

Superior Water Quality

When it comes to storing such a precious commodity as water, purity is non-negotiable. Monofilament liners excel in maintaining water quality:

Smooth Surface:

The smooth surface means no creases where bacteria or sediment can hide, keeping water cleaner for longer.

No Delamination Risk:

Unlike reinforced liners, which over time can experience layer separation, monofilament liners are a single continuous material, ensuring no contaminants enter the water through compromised liner integrity.
All of Puraflo’s monofilament liners meet the stringent Australian Standard AS4020 for drinking quality, ensuring that water remains safe and clean for consumption.

Breathability: The Hidden Advantage

Monofilament liners bring an often-overlooked benefit when compared with reinforced linings: breathability.

Minimal Air Permeability:

This reduces condensation between the liner and the tank wall.

Corrosion Prevention:

Reduced moisture means less opportunity for a steel tank to develop rust, further extending its lifespan.

Long-Term Durability

Investing in a water tank is a considerable outlay, and durability should therefore be a key factor in ensuring you get the most from your purchase. Monofilament tank liners offer:

UV Resistance:

They can withstand Australia’s intense sun without degrading, unlike some alternative materials.

Chemical Resilience:

Their resistance to a wide range of water treatments makes them ideal for both rural and urban water storage.

Temperature Tolerance:

There’s year-round reliability as integrity is maintained in extreme temperatures, from scorching summers to chilly winters.

Environmental and Economic Impact

Choosing a monofilament liner benefits not only your water storage system, but also the environment and your budget:

Reduced Need for Replacement:

With a longer lifespan, monofilament liners reduce the need for frequent replacements, saving you time and money while reducing waste.

Water Conservation:

Better water quality reduces the need for frequent cleaning or water replacement, conserving resources.

Energy Efficiency:

Fewer replacements and lower maintenance requirements result in less energy consumption over time.

Making the Right Choice for Your Water Storage Needs

High-quality tank liners have a big job to do when it comes to protecting your water supply, ensuring it remains clean and safe for consumption. And, when selecting a liner for your steel water tank the evidence clearly points to monofilament options as being the best choice for long-term water storage solutions. They provide:
  • Superior flexibility and strength
  • A custom fit for optimal performance
  • Enhanced water quality
  • Improved tank longevity
  • Better environmental and economic outcomes
