Is Your Rainwater Tank Really Safe?
Crystal clear doesn’t always mean clean.

Across Queensland, thousands of homes rely on rainwater tanks for drinking, bathing, cooking, and washing, but most don’t realise how easily that tank water can become contaminated.
From roofing debris to microscopic bacteria, untreated rainwater poses hidden risks that grow over time.

At Creek to Coast Plumbing, we install whole-house filtration systems that make rainwater safe, clean, and reliable.

We recommend and install the Puretec range, one of the most advanced and trusted home filtration systems available in Australia. Whether you’re relying on tank water full-time or using it as a backup supply, we make sure your system is tailored to suit your property and your needs.

Our team can help you future-proof your rainwater collection setup from the ground up, with properly installed water tanks, secure guttering, and safe plumbing designed to reduce contamination risks at the source. It’s all about long-term water quality, from roof to tap.

What’s Really in Rainwater?

Raindrops might fall clean from the sky, but the moment they hit your roof, they’re picking up:

• Dust, ash, smoke particles
• Bird, bat, and possum droppings
• Pollen, plant matter, and insect fragments
• Lead, copper, zinc or asbestos from old roofing
• Runoff from pesticides or nearby traffic emissions

And that’s just the visible stuff. Beneath the surface, tank water can also become:

• Highly acidic, causing blue/green staining and pipe corrosion
• Full of bacteria, including E. coli and salmonella
• Loaded with tannins, sludge, and sediment that discolour water and reduce quality
• Unpleasant to taste, even when it looks perfectly clear

Safe Rainwater Starts With Better Collection

Many water quality issues start before the tank — at the gutter line. That’s why Creek to Coast offers end-to-end rainwater system support, not just filtration. Our licensed team can help with:

• Custom rainwater tank installations
• Guttering and downpipe upgrades
• First flush diverters and leaf strainers
• Tank inlet screens and overflow solutions
• Stormwater-safe drainage around tanks

When your gutter system is clear, your tank is sealed, and your water is filtered, you’re drastically reducing the chances of contamination — and improving the safety of every drop.

Why Whole-House Filtration Is the Gold Standard

Even if your tank is perfectly clean, rainwater can still carry acidity, fine sediment, and microscopic bacteria into your home.

Creek to Coast Plumbing installs Puretec whole-house rainwater filtration systems, including:

• Carbon filtration – removes taste, odour, tannins, chlorine and fine particles
• UV disinfection – neutralises 99.9% of bacteria, viruses and pathogens
• pH correction – protects pipework by balancing acidity
• Integrated pressure pumps – ensures even flow across your home

No matter where you turn on the tap — kitchen, shower, garden or laundry — you’re guaranteed water that’s been treated, tested, and made safe for your family.

Which Puretec System Suits Your Setup?

System	Best For
Hybrid Plus	Homes using rainwater as their sole water supply
Hybrid G13/G7	Properties with gravity-fed tanks or mains-to-tank switch
Hybrid M12	Under-sink filtration for drinking water only
Tanksafe	Occasional chemical-free tank disinfection

Think Your Rainwater Tastes Fine? Think Again

Just because your rainwater tastes okay doesn’t mean it’s safe. In fact, taste is often the last thing to change when water quality declines.

Many Queensland homes on tank water experience copper leaching without even knowing it, the result of acidic rainwater reacting with pipework, leaving a faint metallic aftertaste and causing blue-green stains around taps and sinks. Over time, that same acidity can begin to eat away at your plumbing from the inside, corroding fittings and shortening the lifespan of your entire water system.

Even naturally occurring organics in your tank, like tannins from leaf litter, can discolour water and leave unsightly marks on laundry, bathroom surfaces, and porcelain.
And if sediment is allowed to build up, it can gradually clog appliances, reduce water pressure, and compromise efficiency.

Filtered rainwater, on the other hand, tastes clean, smells fresh, and flows consistently — giving you confidence that every tap in your home delivers water that’s as safe as it is pleasant to use.
