Tips for Choosing Water Tanks for Your Property


Tips for Choosing Water Tanks for Your Property

There are many benefits to be enjoyed by buying water tanks for your property. Once you have tanks collecting rainwater, you don’t have to rely so much on government-supplied water, which is particularly helpful if you live in an area often in drought and with water restrictions.

Plus, use water tanks and you can help the environment, reduce your water bills, and have more water on hand to
irrigate your gardens guilt-free and keep everything lush and green, no matter the weather. There are numerous water tanks on the market these days, though, so if you’ve never made this kind of purchase before, it can be hard to decide. Follow a few tips, and you should find the process easier and quicker.

Know How You Want to Use the Water

To choose the right water tank, get clear about how you want to use the water you collect. If you purely want to take the water from your tanks and use it for outdoor tasks, such as watering the garden, washing the car, or cleaning outdoor areas, for instance, you can choose and install whichever product you like. Most water tank suppliers could install it for you, too.

On the other hand, if you plan to use the collected water in your hot water system, washing machine, dishwasher, toilets, or the like, a licensed plumber will have to carefully connect the tank(s) to your main water supply. If you want to be able to use the water for drinking, there is even more to think about.


Different governments and municipality offices have different rules and regulations that apply to water supplies in their regions. As such, you must do specific research to find out what is and isn’t allowed in your local area. You may need to submit a development or building application to add any water tank to your yard, or you may need to for some types but not others. Plus, there are typically very stringent rules around drinking collected rainwater, as well as issues regarding mosquito breeding near or in water tanks.

You may need to adhere to set rules regarding things like where a tank can sit, its height or color or type, how it’s labeled, or even noise regulations for its pump or other factors. Furthermore, there may also be legislative requirements to comply with regarding incorporating energy and water-saving features into your water tank plans.

Types of Tanks

Next, it’s time to learn about the different types of tanks. There are various options to choose from, all with different pros and cons and price points. You first need to decide if you want to go down the route of having an underground tank put in, or if you’ll add an aboveground one.

Those put in underground require excavation machinery, concreting, and significant labor costs, as well as costs for things like site surveys and approvals. This makes them a big financial commitment.

Aboveground tanks are more affordable but again, there are numerous types and budgets to decide between.

When you go to buy water tanks for your property, you must decide what material you want them to be made of. Metal tanks are built from flat-rolled or corrugated metal that’s coated or galvanized. They usually have a plastic inner lining. Polyethylene tanks are good for people who live near the beach since the plastic doesn’t rust. They often have bladder storage made from PVC or geotextile or other synthetic materials.

Fiberglass tanks are also resistant to rust but are more expensive than plastic ones. They’re designed to withstand extreme temperatures. Concrete tanks usually get installed for industrial and agricultural purposes, as they’re particularly hardy and won’t blow away, rust, burn, melt, or otherwise have issues. They’re more expensive and often larger than most homeowners require, though.

Before buying, consider the weather around your home. Think not just about how tanks will handle different conditions, but also, for instance, if the water inside them will become untenable if the temperature drops or heats up too much.


Deciding on the right sized tank for your needs is another key factor. Your requirements will come down to the size of your household, what you want to use the water for and when, and the space you have available on your land to house a tank.

If you don’t have much room in your garden and want an aboveground tank, consider a slimline product you can
put in a narrow space or a short, squat tank you could place underneath a deck.

Other things to keep in mind include your roof area and the annual rainfall in your region – if you live in a rainy
area, you’ll need a larger tank than someone who lives in a drier spot.

Water tanks can be a real savior in this day and age with such unpredictable weather and expensive utility costs. Be sure to choose your tank wisely to ensure you get the best value out of it as possible, now and into the future.

Ann, thank you so much for your very interesting article about choosing a water tank for your property. I really like how you said that concrete tanks are durable and won’t rust or melt. I think that it would be very beneficial to find a reputable concrete water tank service to buy one from for the best industrial results.

Really helpful content. Thank you so much for sharing your ideas with us. I literally know that plastic release toxin into the water and poisons water.

So I am a little bit confused about using a plastic water tank for drinking water. Are plastic water tanks safe to use for drinking water?

    Ann says March 1, 2021


    Thank you so much for your question! Plastic water tanks or any water containers are safe for drinking water as long as they are UV-protected food-grade polyurethane resin tanks that are approved by the FDA.

    These tanks will not release anything harmful into the water and are recognized as a completely safe and practical way to store water for drinking and cooking purposes. We hope that answers your question!

    Thank you,
