Are Rainwater Tanks Worth It?

by Feb 10, 2021Help & Advice

Are rainwater tanks worth it? Well consider that a maintained rainwater tank can last up to 30 years and over that time can provide significant savings on your water bills, help our water shortage crisis and provide you with fresh water during times of water restrictions and droughts. 

Rainwater Harvesting is getting more popular every year


The rain that falls from the sky is rich in nourishing nutrients, but also potentially contains waterborne pathogens, industrial pollutants and more. With the advent of chlorination in the 1900s, the developed world largely said goodbye to dysentry and cholera, and now we don’t think much about the water that flows abundantly from the mains water supply to our taps – except, of course, when we get our water bill, or when water restrictions mean we’re stuck with 3-minute showers.

Fortunately, you don’t have to rely entirely (or even mainly) on mains water. Rainwater harvesting via a water tank is becoming more popular every year, including in urban settings. With many Australian towns facing water restrictions, and some even edging close to Day Zero (running completely out of mains water), we’re increasingly putting Australia’s water security first by installing water tanks.

But it’s not just planet-friendly: it’s actually better for your home and your wallet alike. To decide if rainwater tanks are worth it – here’s what you need to know.

Your garden will never be greener!


There’s nothing sadder than a thirsty lawn and garden in summer, especially when you’ve been tending to it year-round and have to lose all your hard work! With a water tank, you don’t need to worry about the impact of water restrictions on your lawn: just use the rainwater you’ve harvested directly on your lawn and garden. And because it’s unchlorinated, it’s actually better for your garden because it’s still chock full of valuable nutrients that plants love.

Cheaper water bills.


Most of the water you use in your property isn’t actually used inside your house; it is predominantly used on your lawn and garden, and in your laundry. Next up is your laundry. Even if you just use your harvested rainwater in your garden, you’ll save a pretty penny; if you get a licensed plumber to plumb your water tank into your laundry room, for a small upfront investment you can have decades of significantly cheaper water bills. Finally, if you supply rainwater to your toilet tank, you’re saving even more. Within a few years, you’ll have paid off your upfront costs, and after that you’ve got decades of savings ahead of you.

Accessories can help you up your water tank game.


 From fighting fires to purifying your water so it’s safe for drinking, there’s a variety of accessories to suit the way you use your water. For example, a rainwater tank pump will help you use your rainwater for a wider variety of chores, and help you pump the stored rainwater to more parts of your home. A firefighting pump is great to have if you live in a bushfire prone area, and an effective whole-house water filtration system means you can drink pure, clean rainwater straight from your tap.

Materials matter.


There’s a few major materials used to make water tanks, each with their advantages and disadvantages. “Poly” plastic water tanks are the cheapest in terms of upfront cost, but they have the shortest lifespan, which makes them a bit of a false economy; fibreglass water tanks are a bit more expensive but have a slightly longer lifespan. Unfortunately, neither poly nor fibreglass are generally recyclable. Concrete water tanks are generally only used for commercial settings, largely because of cost, but they do have the longest lifespan. A great middle-ground is steel water tanks, with around 20-30 years of lifespan at an affordable price. At Select we supply stainless steel and colorbond water tanks in a huge range of custom sizes. 

Slimline vs round water tank – which is better?


When you think about water tanks, what comes to mind is probably round water tanks as frequently seen in countryside settings such as farms. Round water tanks are a popular choice in regional areas, and often seen in suburban backyards as well; they’re a bit cheaper than slimline water tanks. However, slimline water tanks are rectangular, helping urban dwellers make the most of their available space; they’re widely considered to be more attractive, and they can be positioned in those tight spaces alongside your house. You can find out more via these features on stainless steel round water tanks and slimline water tanks.
