Is Rainwater Safe to Drink?

The short answer is yes, as well as there being a host of other health benefits of rainwater for you and your home that don't involve drinking. Rainwater is the main source of fresh water in one way or another, whether it is being used to fill reservoirs, springs or dams, or collected in a rainwater tank, and is collected by millions around the world for drinking, bathing, cleaning and irrigation.


Rainwater is a naturally pure and inexpensive source of water. It contains very low levels of dissolved minerals and pollutants, making it ideal for drinking water. Rainwater harvesting is an inexpensive source of clean water for people in areas with no access to tap water, mains water or any other form of water supply, and can pack some serious health benefits as well. Not to mention, that if you ask anyone from rural parts of Australia - it just tastes better!


Does rainwater need to be filtered?

All Australian state and federal guidelines suggest that water from rain harvesting in rural areas is free of toxins and safe to drink, and as long as you aren't collecting from a contaminated source - such as a roof with a wood burner, or coated with a lead based paint - your collected rainwater will be fresh and clean for your family's consumption.


This means that in most areas of Australia - and all of those that call for use of a rainwater tank - your harvested rainwater will be safe for drinking, cooking and cleaning, and comes stacked with benefits around the home.


If you are still concerned about any toxins or chemicals that may be found in your water, and think further filtration may be required, it won't do any harm, and can simply be fitted to any taps you are going to be drinking water from.

The Aqualiner Fresh® antimicrobial water tank liner

An added benefit of a Pioneer Water Tank is that it comes with the industry-leading and revolutionary Aqualiner Fresh® water tank liner. This clever piece of innovation uses silver ions in the liner to help keep your water clean from the inside of the tank, fighting off harmful bacteria, algae or other contaminants that may try and form in the tank.


This technology was developed with the team at Sanitized®, and is standard in all Pioneer rural rainwater tanks, ensuring that you can rest easy in the knowledge that your harvested rainwater is clean, fresh and healthy.

May promote a healthy pH balance

Without the added chemicals found in tap water, such as fluoride and chlorine, rainwater has a naturally low pH level, similar to that of distilled water, which some studies show may promote a neutral blood pH level and promote better bodily function.


Though these benefits require more study, rainwater is clean, healthy and perfectly safe to drink, and most people who try it much prefer the taste - even when put in your morning cup of tea or coffee - when compared to tap water.

Benefits Around the Home

As well as being a healthy way to ensure that your family has access to clean and fresh drinking water, the health benefits of rainwater extend to other parts of the home, for your family as well as your gardens and your home itself.


Provided that your annual rainfall is high enough, and that you have adequate space for rainwater harvesting, a rainwater tank for your home should be able to supply adequate water for your entire home. Rainwater harvesting can help reduce your water bill, and help you be more environmentally friendly, reducing your overall footprint.


It is important to ensure, for clean rainwater collection, that your rainwater harvesting system is free from debris or contaminants that may find their way into your stormwater before it reaches the tank.

Better for your skin and hair

It is a well known fact that your hair often feels soft, curly and full of life after getting caught in the rain, and this is owed to the low pH level of water thanks to the lack of other minerals found in it. This means that when it comes into contact with your hair, it takes with it any other minerals or chemicals that may have bonded with your hair.


Thanks to its low pH level, rainwater works great with soaps and other products that clean your skin or face, as it is absorbed better by the water, and as such is better applied to the surface it is cleaning. This can help with clearing up acne, or simply making your cleaning products go further. The same is true when you are showering, as the water will help your soap remove any grime or grit from your body.

Helps your plants and gardens thrive

Rainwater has been shown to be extremely beneficial water source for plants and gardens. Have you ever noticed that after a rain fall, gardens and lawns look greener, cleaner and lusher?


The main reason for this is the aforementioned pH of the water, which means it is higher in oxygen and nitrogen than tap water or ground water, which are - above all else - the two major elements responsible for making plants green. In a thunderstorm, these chemicals combine with the rain to create nitrate - a commonly used fertiliser - which is immediately taken in by a pants roots and leaves.


Nearly all plants are susceptible to chlorine toxicity, which can result in the browning of leaves, and rainwater will prevent this, and even in some circumstances help clean the leaves and roots of plants. The carbon dioxide brought down with the rain helps release micronutrients in the soil such as copper, iron, manganese and zinc.


Rainwater is also free from the sodium and heavy metals that may be found in groundwater or municipal water supply - what is referred to as hard water - and these can also cause damage to the root systems of plants and gardens.

Improves the efficiency of your washing machine

Unlike hard water sources - such as tap water or mains water - rainwater is what is referred to as soft water. The hardness of water refers to the dissolved mineral content in the water.


While typically safe to drink, hard water makes soap less effective, in the sense that instead of building up a nice lather, it turns it into a greyish cream - you may have noticed white or grey lines or washing powder on your laundry when hanging it out.


Rainwater helps the detergent do the job it was designed to do, and can also help dissolve minerals out of the clothes that may be making them stiffen up, helping you achieve softer, cleaner laundry.

Easier on taps, tiles and bricks

Another downside to hard water is the deposits it leaves on all surfaces it comes into contact with. While harmless, these deposits can reduce the flow of taps and showerheads, leave stains or build-up on tiles, and even mark bricks or retaining walls outside of the home.


Thanks to its lack of minerals and chemicals, rainwater doesn't leave these same unsightly marks or calcium build-up on the things it comes into contact with, making your maintenance and cleaning significantly easier.
