Stop Drinking Rainwater Without Filtration!

For decades, many of us have relied on rainwater harvesting as a sustainable and cost-effective way to supplement our water supply. But let’s be honest, have you ever really stopped to consider the quality of that water without filtration? Sure, it’s free, it’s natural, and it’s been filling up your tank for years. But is it really as clean as it seems? Is it helping or hindering your body?

You might think that rainwater is a pure and natural resource, but the reality can be quite different. After rainwater lands on your roof it can pick up a variety of contaminants. From the carcasses of rodents to the droppings of birds, your house roof and tank can become a breeding ground for bacteria and viruses. You may not realise it, but you could very well be sipping and swallowing this silent threat.

Pesticides, fertilisers, and industrial pollutants can also seep into your rainwater, posing serious long term health risks. Additionally, old roofs and gutters made of materials like lead and copper can also leach harmful metals into your water supply. Would you not agree that your health deserves better than this?

You may not wish to acknowledge it, but consuming contaminated rainwater can potentially lead to a range of health issues, including gastrointestinal illnesses, skin infections, and respiratory problems. Why let you and your family experience this unnecessarily?.

There are many studies out there to confirm this reality. A CSIRO researcher recently conducted a study of rainwater tank safety in Melbourne, she stated "When we inspect the rainwater, you do find all sorts of nasties in it, waste from possums and birds and snakes sometimes’’. She continued to say ‘’It's not so strange because your roof is your catchment and you'll find creatures like that on there"1

It’s common to think, “I’ve been drinking rainwater all my life and haven’t had any issues.” But here’s the thing, just because you haven’t noticed immediate symptoms so far, doesn’t mean the water is harmless. It is widely acknowledged across environmental health that many contaminants in water can cause slow damage over time. Heavy metals like lead can silently accumulate in your body, potentially affecting brain function and kidney health. Is it really worth taking that chance?

Plus, not all effects of contaminated water are instant or obvious. Some bacteria and viruses may trigger mild symptoms that you dismiss as a “stomach bug” or fatigue, but they can be indicators of something more serious. Even if you’ve avoided illness so far, are you willing to take the gamble with your family’s health for another 10, 20, or 30 years? Why not be proactive? Filtration isn’t about fixing an obvious problem, it’s about prevention and protecting your long-term health.

Some people rely on boiling water to kill bacteria and viruses. While these steps can be helpful, they don’t address the full scope of contamination. A fundamental principle in water treatment is the fact that boiling water doesn’t fully remove heavy metals, pesticides, or other chemical pollutants. Comprehensive filtration is the only way to ensure your rainwater is truly optimal for you and your family.

A good filtration system doesn’t just improve the safety of your rainwater, it enhances its taste and quality too. Imagine never having to worry about whether your water is clean enough to drink! Whether you’re using rainwater for drinking, cooking, or even bathing, filtration protects your entire household from unseen risks. It’s a small investment for priceless peace of mind.
