Water is more expensive than we realize.

In fact, Australian households spend over $5 billion on water every year. But we all need water to live. It may seem like one of those costs you just have to suffer through.

But that isn't necessarily true.

Every time it rains, you have natural, clean water falling directly on your head.

That's right. Rainwater can actually reduce the amount you pay on water and save you money. But if you're not prepared to catch it, you're wasting all those potential savings.

That's why you need a rainwater filtration system.

Keep reading to learn what a rainwater filtration system is, what it does, and how you can use it.

What Is a Rainwater Filtration System?

A rain filtration system gives you a way to catch, store, and clean falling rainwater. Some of these systems are large and complex, but they can be as simple as a plastic bucket.

When rainwater falls onto your roof, it usually pours into the gutters, pours into the dirt, or runs into the street. A rainwater harvesting system will redirect all that water into a storage tank, or whatever is being used to hold the water.

From there, it either gets filtered automatically as part of the system, or it sits and waits until you need to use it.

There are many different kinds of filtration systems that all depend on what you're planning to do with the water. But we'll get into that later.

Why Is This Important?

For a lot of people, rain has been the main source of drinking water for thousands of years. Today, rain can be a renewable source of sustainable water for your home.

It also has a lot of positive environmental benefits.

For example, catching rainwater keeps it off the ground and out of the stormwater drain, decreasing the chance of erosion and flooding from water runoffs.

It puts less strain on the community water supply because you aren't using that water for your home, leaving more water for other people.

Rainwater is a free, natural resource and it saves you a lot of money on your water bill!

What Does Using Filtered Rainwater Mean Exactly?

Whatever you want it to mean. You can substitute rainwater for anything you usually use water for.

You can use rainwater for your showers; you can use rainwater for washing your clothes; flushing your toilets; growing plants; or doing the dishes. You can even use it for cooking and drinking water if you're careful.

Rainwater is naturally free of any pollutants, salts, minerals, and other man-made contaminants found in other water, making it an especially healthy choice for irrigation. But, this can vary depending on where you live.

How Does It Work?

Once you know how you want to use rainwater, you can decide on the type of filtration system you want.

If you like the sound of using rainwater for your entire house, you can install a big system, like a large catchment tank, directly into your home plumbing. These kinds of tanks have built-in filtration systems, such as an APEC 5-Stage Reverse Osmosis system.

This kind of tank may cost a bit of money to get set up, but it will save you money in the long run.

If you prefer using rainwater for only a few chores, like washing the car, you can set up a much smaller and cheaper filtration system.

You have a lot of different options to pick from. A common choice is a first flush system. However, with that system, you have to get rid of the first batch of water because it has the most contaminants. It also requires more maintenance to work properly.

A more modern solution is to use the Ultraflow Stormwater filter. It uses a fine metal grill to filter out particles and has the option of a fine mesh to capture and filter particles down to 150 um.

When it's done raining, bring what you've collected inside and run it through your countertop filtration system.

Can I Drink Filtered Rainwater?

In some cases yes, in some cases no.

That isn't very helpful on its own, so let's dig in a little deeper here.

You can drink rainwater, provided you've handled it carefully and filtered it correctly.

You're probably thinking: "But I thought rainwater was clean?"

It is--certainly cleaner than the water found in rivers and lakes--but that doesn't make it clean enough to drink without proper filtration. And it has a lot to do with where you live.

Rainwater collected in remote areas, like the mountains, will be a lot cleaner than rainwater collected in big cities.

Why?

Rainwater does contain bacteria, parts of plants and bugs, and it can carry chemical materials it has washed out of the sky.

What's the Verdict?

If you run your rainwater through high-quality filters, the water should be safe to drink. However, rainwater, similar to distilled water, has little to no minerals.

If your body doesn't get these minerals normally found in water, it can have a negative effect on the metabolic function and send your electrolytes out of balance.

If you do decide to drink a lot of it, you should consider adding liquid ionic minerals to your food or drink to supplement it, like Celtic sea salt. Though the best place to start is by collecting the water in the first place and filtering it before it enters the tank. That way you can choose what you want to use it for after.

The Benefits of a Rainwater Filtration System

When it comes down to it, there aren't a lot of negatives to adding a rainwater harvesting and filtration system to your home. It helps the environment, saves more water for the community, and saves you money.

Before the next rainfall, make sure your house is equipped with its own rainwater filtration system.
