Danger Pond Water Do Not Drink Sign displayed in front of a pond

From Pool Rules to Bore Warnings: The Aussie Guide to Water Signage

Water is life—but it's also a silent risk. From tranquil dams to backyard swimming pools, Australia's landscape is a patchwork of aquatic environments, each with its own hidden dangers. That’s where water signage steps in—not just as a legal checkbox, but as a lifesaving layer of communication that turns visual cues into survival instincts.

Whether you’re on a rural property with a borehole, managing a suburban pool or simply walking your dog past a pond, water signs are the frontline defence against accidents. Let’s dive deep into the types of water signage used across Australia, why they matter, and how they help keep our communities safer.

What is Water Signage?

Water signs are specially designed visual signs installed near water sources to inform, warn and guide people about safety practices, potential hazards or usage restrictions. Think of it as the universal language of aquatic safety—a way to tell someone, “don’t swim here,” or “this water’s not safe to drink,” even if they speak a different language or can’t read at all.

Why Water Signage Matters

Water signage isn't just for show—it serves some serious purposes:

  • Identifying Hazards: From strong currents to slippery rocks, signs alert us before we step into trouble.

  • Promoting Safe Practices: They remind us to wear life jackets, use the correct entry points or avoid diving.

  • Preventing Accidents: A well-placed sign can be the reason someone thinks twice before leaping in.

  • Ensuring Compliance: Councils, developers and landowners must meet regulatory standards to avoid legal liability.

Bore Water Signs

Bore water is groundwater that’s accessed by drilling a borehole into an underground aquifer. Bore water is widely used across regional Australia, especially on farms, outstations and remote communities. But here’s the kicker: not all bore water is safe for drinking. Many bores tap into aquifers with high mineral content or potential contamination.

That’s where bore water signs come in. These typically fall into the Informational or Prohibition categories and use clear warnings like:

‘Potable water’ is the term often used on these signs and it refers to water that is safe to drink or use in food preparation. It’s been treated, filtered, or naturally meets quality standards to be free from harmful contaminants, bacteria, and chemicals. In Australia, potable water must meet the Australian Drinking Water Guidelines set by the National Health and Medical Research Council (NHMRC). If a water source is not labelled as potable, it should not be consumed.

These signs are critical for protecting both humans and animals from accidental consumption. In rural schools, caravan parks and agricultural sites, proper water signage around bore sources ensures everyone knows what’s safe and what’s off-limits.

Pond Signs

Ponds may seem harmless—until they're not. With unpredictable depth, poor visibility and potential for slippery edges, ponds can pose drowning risks, especially for children and pets. In Australia, many ponds are man-made and found in parks, golf courses or nature reserves.

Common pond signs include:

These are typically Warning Signs or Prohibition signs, using yellow triangles or red circles. Their purpose? To draw attention fast and prevent people from underestimating a seemingly calm body of water.

Water Tank Signs

Australia leads the way in rainwater harvesting, and domestic water tanks are common in both metro and regional areas. But not all tank water is created equal. Many tanks collect water that’s safe for gardening but not for human consumption.

Enter: Water tank signs.

Some standard examples include:

These Informational signs prevent confusion, especially in shared spaces like schools, sports grounds or multi-tenant buildings. A simple sign on a tap can stop someone from filling a drink bottle with unsafe water—a small gesture with a huge health impact.

Drinking Water Signs

Not every tap in the wild is your friend. When travelling through bushwalking trails, remote townships, or even urban parks, drinking water signs clearly mark where it’s safe to hydrate—and where it’s not.

These signs often use green squares or blue circles to signal a Safe Condition or Mandatory action. Examples include:

This is where water signage intersects with public health. Clear identification of safe drinking sources helps reduce illness and encourages hydration without hesitation—especially important in Australia’s scorching summers.

Swimming Pool Signs

If you’ve spent time at a public pool or manage a private one, you’ll know that pool signage isn’t optional—it’s law.

Australian standards require multiple types of signs around pools to maintain safety and prevent injury. 

Key Swimming Pool Signs include:

Beyond the legal obligation, these signs play a vital role in crowd control, reducing risk and ensuring everyone knows how to behave in a shared aquatic space.

Deep Water Signs

Whether you're near a dam, reservoir or beach access point, deep water signs serve a stark reminder: the water here means business.

Typical warnings might include:

These are often large, high-contrast Warning signs placed near public access areas, especially where rescue might be difficult. In Australia’s unpredictable bushland and coastal zones, they serve as crucial deterrents to overconfidence.

Placement & Maintenance: The Silent Enforcers

A sign is only as good as its visibility.

Best practice in water sign placement includes:

  • Eye-level installation

  • Placement at entry points, high-risk zones or visibility choke points

  • Weather-resistant materials

  • Regular checks for fading, damage or vandalism

Councils and private operators alike are responsible for maintaining signage to remain compliant and effective. A missing or unreadable sign is a lawsuit waiting to happen—or worse, a tragedy.

Water Signs Save Lives

Water signs are more than aluminium and ink. They're lifesaving tools that speak volumes with just a symbol and a colour. In a country where water is both beloved and brutal, understanding and respecting water signage can mean the difference between a day out and a disaster.

So next time you pass one of these signs—pause, read and respect it. It might just be the most important thing you see all day.

FAQ's

1. What is the purpose of water signage?
Water signage is designed to inform, warn, and guide people near water sources, helping prevent accidents and promote safe behaviour.

2. Who is responsible for installing water signs in Australia?
Responsibility typically falls on property owners, councils, or facility managers, depending on the site. For example, local governments manage signage at public beaches, while businesses and private property owners are accountable for signage on their premises.

3. Can I drink from a tank if there’s no sign?
Not necessarily. Always look for water tank signage. If a tank is not marked as “Potable” or “Drinking Water,” assume it’s non-drinkable and seek a confirmed source.

4. Why are colours so important in water signs?
Colours in water signs aren’t just for style—they convey critical information at a glance. For instance, red signals danger or prohibition, yellow warns of hazards, blue indicates mandatory actions, and green shows safety or information. These colours are standardised to aid instant recognition.

5. Where should water signs be placed?
Water signs should be positioned at eye level near entrances, hazards, or high-risk zones like ponds, tanks, and swimming pools, and should remain visible and well-maintained.
