Rainwater Harvesting

Rainwater Harvesting: Simple Solutions for a Thirsty Planet

Clean water should be easy to access. But for many people, it’s still out of reach. Across cities, farms, and remote communities, finding reliable, affordable water can be a daily challenge.

That’s why replacing these traditional sources of water with rainwater harvesting should be our number one priority. It is a simple solution to water scarcity challenges that the world faces every day. With every rainfall, there’s a chance to save money, live more sustainably, and support your local area.

In this guide, you’ll learn how rainwater harvesting works, which collection methods are most effective, and how to set up a system that fits your lifestyle.

You won’t need any special gear or complex installs. Based on our two decades of experience, we’ll show you smarter ways to make the most of every drop.

Ready? Let’s get into it.

What Is Rainwater Harvesting?

Rainwater harvesting means collecting the rain that falls on your roof and saving it to use later.

It’s quite simple to understand.

Rain runs through your gutters, flows into a tank, and waits there until you need it. You can use that water for your garden, flushing the loo, doing laundry, or even drinking it if it’s been properly treated.

What Is Rainwater Harvesting?

This kind of system can take pressure off your mains water supply. It can also save you money on water bills and give you a backup during dry spells or restrictions.

Historical Context

Collecting rain isn’t a new idea. People in Asia, Africa and the Mediterranean were doing it thousands of years ago. Back then, they built smart systems to store water for cooking, cleaning and farming, especially in places where rain didn’t fall often.

The basics haven’t changed much. What worked then still works today with a bit of modern plumbing added in.

How People Use It Today

These days, rainwater harvesting is showing up in homes, schools, farms and businesses. Some systems are as easy as a barrel under a downpipe. Others are fully connected into plumbing systems and used daily.

It’s not just for off-grid living anymore. Even suburban homes are adding tanks to cut costs and use water more wisely.

Our research indicates that homeowners who install a basic system often see savings within the first year, especially in areas with regular rainfall. It’s flexible, low-maintenance, and adapts to many different spaces.

According to the Australian Bureau of Statistics, about 34% of households that could install a rainwater tank had one by 2013. That number keeps growing thanks to restrictions, rebates and more awareness around water use.

How Does Rainwater Harvesting Work?

Rainwater harvesting starts with your roof. When rain falls, your roof acts like a big catcher’s mitt. The water flows into gutters, then down into pipes that lead to a storage tank. The bigger your roof, the more water you can collect. A simple setup like this can catch hundreds of litres during one good storm.

After collecting rain, do these steps to make sure your rainwater harvesting system works great:

  • Filtration: Before the water goes into your tank, it needs to be filtered. This helps remove leaves, dust and other bits that wash off the roof. Most systems use a mesh or leaf screen right at the top of the downpipe. This step is really important, especially if you want to use the water for anything other than gardening.
  • Storage and Use: Once the rain is filtered, it flows into a tank. That tank could be small and tucked in the backyard, or a big one buried underground. From there, you can connect it to a tap, a hose or even your home’s plumbing.

Pro Tip: Paint above-ground tanks a light colour to keep the water cooler. Cooler tanks are less likely to grow algae, so your water stays cleaner for longer.

If you’re considering setting something up at home for your rainwater harvesting, you have more than one option. Let’s look at the different ways you can collect rainwater and figure out what suits your space best.

Water Collection Methods to Try for Rainwater Harvesting

There’s no one-size-fits-all approach to collecting rainwater. The best method depends on your space, your budget, and what you’ll use the water for. Some options are as simple as placing a barrel under a pipe. Others need a bit more planning but store much more water.

Water Collection Methods to Try for Rainwater Harvesting

Here are the most common methods people use at home and in the community:

  • Rooftop Catchment: Got a sloped roof? You’ve already got most of what you need. This method uses your roof as the collection surface, guiding rainwater through gutters and into a storage tank. A 100-square-metre roof can catch up to 1,000 litres from just 10 mm of rain. It may cost around $800- $2,000 to set up a complete system, including tank, pipes and fittings. 
  • Rain Barrels: A low-cost (you can get a basic barrel for $100–$300) option that’s perfect for small gardens or patios. You place one at the bottom of a downpipe, and it catches roof runoff during a shower. They’re ideal for watering plants, washing outdoor gear, or cleaning tools. 
  • Ground Catchment Systems: Have a big yard or open paths? This method lets you shape your land to collect water. Swales or shallow channels guide rain into garden beds or a tank. It’s a great option for farms or wide suburban blocks. A bonus is that it helps reduce erosion and keeps your soil moist longer.

We helped a small school in Brisbane install three rain barrels and a rooftop catchment system on their science block. The project cost only $1,500. Now, they use the water for gardening classes and to flush toilets, and their water bill has dropped by nearly 40%.

With the right system in place, households and neighbourhoods can achieve the same or even more. Let’s look at how these methods connect to broader goals around sustainable water use.

Sustainable Water Solutions for the Future

Sustainability means using what we need today without harming what’s available tomorrow. When it comes to water, that means thinking beyond the tap and planning for the long run. With droughts becoming more common and populations growing, smart water use has become necessary.

Smart water habits help your home and your community. When more people collect and use rainwater, it eases pressure on shared systems and builds stronger, more self-reliant communities.

Sustainable Water Solutions for the Future
  • Support During Dry Spells: Public water systems can struggle during droughts. When more households use rainwater tanks for daily needs, rainwater lightens the load. That means fewer restrictions, fewer supply issues, and more flexibility when it matters most.
  • Practical for Schools and Shared Spaces: If you install small rainwater harvesting systems at schools or community gardens, it can supply rainwater for toilets, cleaning, or even drinking. These setups teach young people about sustainability and cut costs, too.
  • Long-Term Savings: Over time, rainwater harvesting pays for itself. Fewer litres from the tap means lower bills as you use a resource that falls freely from the sky. It’s one of the simplest long-term water solutions out there.

Rainwater harvesting also helps take care of the planet. It means less dirty water running into drains, rivers, and oceans when it rains. It also means we don’t need to pump and treat as much water, which saves energy. And by using rain instead of drawing from dams or underground, we help nature stay in balance.

More people are choosing water systems that are smarter, simpler and better for the planet. These are the stepping stones to a more thoughtful way of living. And it all starts with one good idea, right at home.

Save Every Drop of Water for a Better Future

Rainwater harvesting helps you save water, but it also supports a simpler, more thoughtful way of living that benefits your home, budget, and planet. We’ve covered how it works, the methods you can try, and how it fits into a more sustainable future.

No matter where you live or how much space you have, there’s a way to make it work. It might start with a simple rain barrel. Or maybe it’s a full tank system feeding your garden, laundry or toilet. What matters most is that you begin.

At Easy510, we’re committed to making safe, sustainable water solutions more accessible, especially in communities that need them most. If you’re ready to be part of that change, take the first step today.

Bottled Water's Hidden Cost: Environmental & Economic Impact

Bottled Water’s Hidden Cost: Environmental & Economic Impact

You’ve been told bottled water is cleaner, safer, and better. But the truth is, it’s not. While it’s a necessity in some countries with unsafe water, in many areas, like Australia, it’s just a habit.

It’s a cleverly marketed illusion that costs you more, gives you less, and leaves behind a mountain of plastic waste. What you’re really buying is a single-use convenience with a centuries-long consequence.

Think about it. While your tap water (often just as safe) is readily available at home or work, you reach for bottled water because it’s easy, familiar, and packaged to look “pure.” But behind that convenience lies oil extraction, carbon emissions, plastic pollution, and an industry designed to profit off your doubt.

Billions fall for the same trap every year. But this is one habit you can change easily and with real impact.

Let’s talk about what bottled water is really doing to the planet and to you.

Why Bottled Water Pollution Is a Major Problem

Think one bottle doesn’t matter? Every single-use bottle contributes to a growing crisis that is choking our planet. The plastic used in bottled water can take centuries to degrade. In many cases, it doesn’t degrade at all, ending up in ocean currents or buried in landfills.

Each bottle begins in an oil field, where fossil fuels are extracted. It’s then:

  • Moulded into shape
  • Filled and sealed
  • Shipped across cities or even continents

Every step of making bottled water uses up energy and adds carbon to the air. And in the end, it’s all for something that gets used once and tossed.

Most bottles don’t get a second life. In fact, only about 9 percent are ever recycled. The rest linger in the environment, slowly breaking apart. That bottle you tossed after lunch may still be around long after you’re gone, contaminating soil, waterways, and wildlife habitats.

When plastic doesn’t go away, nature pays the price:

  • Sea birds are found with stomachs full of plastic.
  • Marine animals choke on fragments or starve from ingesting them.
  • Microplastics are now turning up in drinking water, seafood, and even human blood.

What we’re dealing with is bottled water waste and an industry optimised for speed and sales, leaving behind damage that no recycling bin can fix.

Every plastic bottle reminds us that a million bottles are sold globally every minute. Yet over 90 percent never get recycled. Most of that plastic will stick around for more than 400 years. And compared to tap water, bottled water has a carbon footprint that’s about 1,000 times higher.

When we talk about the cost of bottled water, this is the real price.

So, what about the financial cost, and what are we really paying for with every bottle we buy?

The Hidden Expenses Behind Bottled Water

Bottled water can cost up to 2,000 times more than what flows from your tap. In Australia, it often sells for over $5 a litre (making it the priciest worldwide!), while tap water costs less than a cent. It’s one of the biggest markups in the modern world and more expensive, in some cases, than petrol.

And yet, people buy it without blinking. That’s the power of convenience wrapped in marketing. So, what’s the real price of bottled water?

You’re paying for the water itself, along with things like branding, packaging, refrigeration, and transportation. All of these add up to make the water feel premium. These extras pad the pockets of corporations, while the long-term consequences are left to public systems.

What you’re really funding:

  • Marketing campaigns and glossy labels
  • Single-use plastic production and freight
  • In-store refrigeration and retail markup

Taxpayers end up paying for waste management and recycling programmes that often can’t keep up. Local councils spend millions cleaning up litter. And as microplastics spread through our environment, new health concerns are putting extra strain on healthcare systems.

Even if you never touch a bottle, you’re still helping to pay for the damage.

So what are you really paying for? A clean, simple drink, or a system that profits from pollution?

And yet, despite all of this (the cost, the waste, the pollution), bottled water continues to fly off the shelves. Why? Let’s look at the myths, fears, and habits that keep the cycle going.

The Truth Behind Why Bottled Water Remains Popular

If we know bottled water is overpriced, wasteful, and harmful, why do people still buy it?

Because bottled water isn’t only sold as a product. People are drawn by the feeling of safety it offers, and that’s a powerful motivator. Over time, that feeling of safety and ease has become a big part of how we see water.

The Truth Behind Why Bottled Water Remains Popular

Here’s how:

Perception Over Reality

For years, bottled water brands have spent millions sending one clear message: their water is purer, safer, and better. They use pictures of alpine springs and melting glaciers to connect with our feelings, especially around health.

Because of this, many people feel safer buying bottled water, even when it’s no different from the water running from their kitchen tap.

Many don’t realise that in Australia, tap water is rigorously treated and tested under national safety guidelines. In most urban areas, it is not only safe but also better regulated than many bottled alternatives. Still, the branding wins.

Bottled Water as a Lifestyle Signal

For some people, bottled water is also about status. A stylish bottle from a trendy brand can feel like part of the outfit, something you carry in your gym bag, place on a café table, or spot in an influencer’s photo. It’s subtle, but the message comes through: this is a lifestyle. That extra layer of appeal is tough to ignore.

When Habit Takes Over

Beyond just image and perception, bottled water stays popular because it fits so easily into our daily lives. You’re running late, heading to the gym, or stuck in traffic, and there it is, cold and ready at the counter. It’s more of a quick grab than a thoughtful decision.

Take this example: a student dashes into a corner store between classes. The refill station on campus is a few buildings away. But the three-dollar bottle is closer, colder, and quicker. Multiply that scenario by millions of moments across cities, and you have an entire economy built on reactive behaviour.

When convenience, marketing, and habit come together, facts often get overlooked. The real issue isn’t choosing bottled water once, but how rarely people pause to question the routine.

And that is exactly what needs to change.

Fortunately, there are better ways: practical, affordable, and just as easy. Let’s look at what eco-friendly water choices really look like in everyday life.

Better Ways to Drink: Eco-Friendly Water Solutions

Going plastic-free doesn’t mean you have to be perfect. Just a few simple changes that fit your daily routine can have a positive impact. Cutting back on bottled water can be surprisingly simple.

Better Ways to Drink: Eco-Friendly Water Solutions

Start at Home

Start with what you already have. In most parts of Australia, tap water is clean, safe, and regularly tested. If the taste or quality isn’t quite right where you live, try using a simple filter. Jug filters, under-sink systems, or tap-mounted units are affordable and easy to set up. These choices help you feel confident about the water you drink straight from the tap.

Take It With You

Reusable water bottles are everywhere these days and come in lots of materials and styles, such as:

  • Stainless steel bottles last a long time and keep drinks hot or cold. 
  • Glass bottles don’t hold any plastic taste, so your water stays pure. 
  • Flexible silicone bottles are perfect for travel or small spaces.

Pick one that suits your lifestyle and keep it handy at your desk, in your bag, or in the car.

Refill on the Go

Refilling stations are becoming more common in public spaces like parks, gyms, airports, and shopping centres. Some cafes even welcome bottle refills if you ask politely. Apps like “Refill” and “Tap” can help you locate nearby water access points when you are out and about.

Changing your water habits is one of the easiest ways to cut plastic use. Every refill skips a bottle. Every skipped bottle avoids waste. Each small choice adds up.

If you are looking for a place to start, this is it.

But for real change to happen, individuals shouldn’t be the only ones making changes. The bigger challenge lies in holding brands and systems accountable for the damage they have normalised.

The Profit-Driven System That Keeps Bottled Water on Shelves

Bottled water is everywhere because it makes money. That profit comes through a system that avoids taking responsibility at every step, starting with the source, moving through the store shelf, and ending in the landfill.

Most bottled water comes from the same municipal supplies, is treated, and then is repackaged with fancy labels. Yet it sells for hundreds of times more than tap water. The companies that make these profits don’t pay for the waste they create. Instead, the burden falls on councils, communities, and the public.

But why are brands not legally required to take responsibility?

This is enabled by policy gaps and soft rules. Without clear legal obligations, brands are allowed to:

  • Repackage tap water with little transparency
  • Market their products as eco-conscious despite using single-use plastic
  • Avoid financial responsibility for waste and environmental harm

Greenwashing tactics help maintain the illusion of sustainability, while behind the scenes, public funds cover the cleanup.

How we can make changes

Real progress begins with stronger laws that make producers responsible for the materials they put into the world.

To make this happen, several major actions need to be taken across industries and governments:

  • Plastic makers and beverage companies should be required to handle their own waste from start to finish.
  • Governments also have a role to play by banning single-use plastic bottles in public facilities and funding accessible refill infrastructure in schools, parks, transport hubs, and workplaces.
  • Clear, honest labelling is equally essential. People deserve to know whether their water comes from a spring or a tap and what kind of impact their purchase leaves behind.
  • Individual effort is important, but it works best when backed by systems designed to make sustainable choices the easiest ones. 

That is how real, lasting change takes root.

Even in the absence of perfect systems or strong laws, there is still something you can do. It begins with the next bottle you choose to avoid.

Bottom line: Every Bottle Is a Choice

We live in a world where ease often wins. But convenience comes with a cost to the planet, to public resources, and to future generations. The good news is bottled water is one of the simplest habits to change.

You do not need to overhaul your life or buy expensive equipment. All it takes is intention. Choosing tap water, carrying a reusable bottle, and saying no to single-use plastic are quiet but powerful forms of resistance.

Try it for 30 days. Skip the bottle. Refill instead. Notice how easily it becomes second nature.

Your everyday choices shape your routine and the world around you. They send a signal and create momentum. And when enough people choose differently, the industry is forced to change too.

It starts with one bottle. Make it count.

Empowering the Next Generation: Water Education in Schools

Empowering the Next Generation: Water Education in Schools

Children soak up what they see and hear. That’s why water education for kids is important to secure the future of the world. Teaching them how water connects to health, fairness, and the environment sets up habits that can last for life.

With over two decades of experience in global water awareness, we’ve seen how early education can spark lifelong change.

In this article, we’ll walk you through how to make water education for kids practical, inspiring, and fun. You’ll find tips for daily habits, engaging classroom ideas, successful youth programs, and resources for families and schools.

Everything here is designed to help children understand water’s value and their power to protect it. Let’s dive in.

Everyday Tips to Save Water for Kids

Children enjoy feeling useful. That makes them great helpers when it comes to saving water. We tried a water-saving chart with our own kids, and fortunately, it worked better than expected.

Each tick in that chart meant a quick shower, a full watering can, or a tap turned off. And every tick made them motivated like they’d won a prize.

Everyday Tips to Save Water for Kids

Here are the water-saving tips that helped us most:

  • Tap off, teeth on: Brushing with the tap running can waste up to 6 litres per minute. Multiply that by two brushes a day, and you’ve got enough water to fill a bucket before breakfast. You can teach this lesson to kids by filling a jug with the same amount and pouring it out together. It will give them a realistic impression of saved water.
  • Bath-time buckets: After a bath, scoop some of the water into a bucket for the garden. Let kids choose which plants get watered with that water. You can also place a waterproof toy boat in the bath and pretend it’s delivering “water cargo” to dry land. It turns a simple act into something fun and memorable.
  • Make water-saving a game: Create a weekly water hunt, where kids will check taps, hoses, and toilet buttons for drips. Let them use a flashlight and call themselves “Leak Seekers.” One drop per second wastes over 11,000 litres a year. Fixing even a small drip becomes something they can take pride in.
  • Make it visual: Hang a water-saving chart on the fridge, the reading room’s wall, or somewhere convenient. Use coloured stickers for each action. For example, blue for brushing, green for gardening, yellow for leak-checking. If they collect five of each by the end of the week, they get a small prize or the chance to choose the next week’s water goal.

Pro tip: Try a sticker chart or a family water jar to track your progress. These tools make water-saving a shared goal and give everyone something to smile about.

Now that we’ve got the basics in place, let’s explore how to make learning about water fun with creativity and imagination.

Creative Ways to Teach Water Conservation

Water conservation means using water wisely and not wasting it. If you teach this to kids at an early age, they will understand that water is limited and important to protect.

We’ve seen classrooms developed with role-play activities. One teacher created “Water Hero Week,” where kids wore capes and kept track of their water-saving powers.

Another set up a water pollution station using jars of clean water, soil, and food colouring. There, the kids added items and watched the water change with so much excitement.

Kids remember what they enjoy in the long run. So, give them lessons they’ll talk about at lunch break or playground hours.

Here are some creative ways to teach the kids about water conservation:

Water-themed board game

What if a board game could teach water facts and spark competition? Use printables with fun questions like “What uses less water: a bucket or a hose?” Let kids roll the dice, collect tokens, or move along water-drop paths.

You can also make your own game with trivia, challenges, and silly penalties like “do a fish dance.” It’s active, screen-free, and kids remember more when they’re laughing.

Water-themed board game

Set up a simple experiment

Pollution can feel like an abstract idea until kids see it with their own eyes. Use food dye, jars, and common filters like cotton or paper towels. Have them predict what will happen before pouring.

Talk through what clean vs. dirty water looks like, or maybe you can show an animated documentary relevant to this. Such activities will explain to kids how water gets treated and why it’s important not to dump waste into drains.

Start a classroom art wall

Let kids express their ideas about water through art. Give them paper, markers, and a few starter questions like “What can I do to save water in the kitchen?” or “How can we help our school use less water?”

They can draw or write pledges, design posters, or even create characters like “Captain Save-a-Drop.” Displaying their work gives them pride and keeps water conservation top of mind.

Each activity gives kids something to own and feel proud of. It also helps parents and teachers explain why water matters, without making it feel like a chore.

Want to see how these ideas come to life in schools? Let’s look at real programs that are working.

Youth Water Programs That Actually Work

Schools across Australia are proving that kids can lead real change. In Victoria, the Schools Water Efficiency Program (SWEP) has helped schools save over 1.15 billion litres of water and more than $3.8 million in water and wastewater charges since 2012 (Source: Barwon Water).

We worked with a Brisbane school where students checked toilets using food colouring tabs to find leaks. They found and reported problems within days. That one simple action saved thousands of litres.

Here are some youth water programs that give kids real ways to get involved and learn by doing:

  • Student Water Ambassadors: What happens when you let students take the lead on water education? They step up. Water Ambassadors take turns updating water-saving posters and checking for dripping taps. They help teachers write simple water reports showing where water is being used the most. This will grow leadership and help students understand how daily actions impact water use.
  • Water Smart Gardens: In this program, students manage garden beds using collected rainwater or water from classroom sinks. They compare which watering methods work best and learn how weather and soil affect water use. These hands-on tasks support lessons about water management, food growth, and caring for natural resources.
  • Tank Trackers: Tank Trackers are students who check water levels daily and record them in a log. They use that data to make simple graphs or wall charts. In this way, kids can learn how to work with numbers and understand how collected water is used across school activities.
Student Water Ambassadors

These programs are fruitful for students to see the value of water, understand how to save it, and become active water stewards. Some schools even call their most engaged students YWC (Youth Water Champions). Whatever the program name or approach is, stick to the main goal: letting kids know the reality of water.

Next, we’ll explore practical resources parents and teachers can use to support these lessons at home or in school.

Water Management Resources for Parents and Teachers

We often hear from teachers and parents, “I want to talk to kids about water, but I don’t know where to start.” The good news is you don’t need to plan everything from scratch. There are ready-to-use resources that make it easier to teach water topics at home or in the classroom.

Here are some water management tools and programs designed to support water education for kids in a way that’s fun, clear, and practical:

  • SWEP (Schools Water Efficiency Program): SWEP is a free program that helps Victorian schools track water usage with real-time data. Students learn how to read water meters and spot leaks early. Schools also get regular water reports showing how much has been saved and where improvements can be made. It’s a great way to combine learning with action. 
  • Water Night by Smart Approved WaterMark: Held once a year, Water Night offers lesson plans, activity packs, and games that show how often we use water without thinking. Families and schools can join together and turn the evening into a water-saving challenge. 
  • UNESCO’s Water Education Program: UNESCO’s youth water education tools include global water facts, interactive maps, and downloadable activities for schools. They focus on the quality of water and the importance of access for all. If a school wants to build international understanding of water into its lessons, it could be a strong option.

These resources support both structured learning and casual home discussions. They make water education easier, more visual, and more fun. At the end of the day, parents and teachers can easily focus on helping children build good habits and understand why saving water is important.

Raising Tomorrow’s Water Guardians

We’ve shared simple ways to build better water habits, creative teaching tools to make lessons stick, and school programs that show kids can lead real change. Every small step from turning off a tap to tracking a rain tank helps build lifelong awareness.

Water education for children gives them the support and tools to make smart choices and feel proud of their work. And when parents, teachers, and communities work together, those lessons go even further.

At Easy510, we believe education is the first step to bringing change. That’s why we’re committed to supporting schools, families, and communities with practical water knowledge and clean water solutions.
