A rainwater tank enables you to collect and store rainwater from your home’s roof using pipes. In the past, you’d only undertake rainwater harvesting if you lived on a farm and used the water for agricultural uses. However, times have changed, and with climate change increasingly becoming an issue, you no longer can fully depend on constant water supply from the main grid.

As a homeowner, this isn’t the news you’d welcome as continuous water supply, while usually taken for granted, is something you need for the smooth running of daily tasks, from cleaning to cooking. To cushion yourself from the risk of not having any water, investing in a rainwater tank makes a lot of sense. If you’re unconvinced that the rainwater tank is an excellent investment, here’s a guide to prove why getting one would be a wise decision:

1. Helps You Save Money

After installing a rainwater tank, such as this model, you can start using rainwater without paying a cent to anyone. This is a privilege you don’t have when your home’s water supply is from the main grid. Because of this, you spend less on water bills, which, in the long run, saves you a substantial sum of money.

In addition, rainwater is naturally soft water, meaning there’s no need for treating it using a water softener. And, because buying water softeners can become quite costly in the long term, using rainwater means you don’t have to worry about such an expense altogether.

If you reside in a rural area, the rainwater tank also proves to be a shrewd investment as you don’t need to hire a truck to deliver water to your home. With all these cost-saving merits, you shouldn’t have any reservation about installing a water tank despite its upfront high installation cost.

2. Useful During Emergencies

Your home’s water supply from the main grid gets interrupted from time to time due to natural disasters, such as earthquakes. This can also happen due to unforeseen hindrances, such as pipe damage or low water pressure. During these times, you’re only left with the option of having to fully depend on the stored water as you wait for things to get back to normal. However, you wonโ€™t know how long this can take, as this can take either weeks or months in some cases.

If you have a rainwater tank, you shouldn’t have any worry during these periods. This is because you can continue collecting and storing rainwater to carry out daily home duties.

3. Improves Plant Growth

You can use the harvested rainwater to water the plants and vegetables in your garden. Because the water harvested in the rainwater tanks doesn’t contain any artificial pollutant and different types of chemicals, it helps flush away salt accumulation. In addition, rainwater doesn’t contain any chlorine.

In contrast, rainwater doesn’t contain any of these contaminants, making it an ideal choice as it’s healthy and clean for the trees and plants. This allows you to save money on your landscaping and property maintenance.

4. Sustainability

Using rainwater tanks to harvest rainwater reduces the demand for groundwater. This is great news considering that groundwater is quickly getting depleted in most areas across the globe. Due to this, people have been forced to dig deeper wells, which is costly and can hurt the environment as it leads to the collapse of soil previously occupied with water.

Using rainwater also helps reduce pressure on the public utilities, hence, reducing the level of water waste. In addition, it lowers the impact of rainwater runoff that can destroy water habitats and creeks.

5. Heavy Rainwater Management

After a heavy downpour, it becomes a huge challenge to control how much rainwater flows on your lawn areas, front yard, and garden. And, with many urban areas today usually densely populated, there seems not to be enough space for rainwater to seep into the ground. Due to this, drainage problems emerge, which eventually lead to flooding.

Owning a rainwater tank helps curb the severity of this problem as you’ll be detaining the water after every storm. This is possible because you’ll manage to collect and channel most of the water into the rainwater tank. And, although you might not have managed to collect all the rainwater, you’ll have considerably reduced the water quantity that finds its way into your home’s outdoor spaces. Therefore, local pools won’t form and attract unwanted insects. like mosquitoes, which might cause illness to you or other family members.


If you’re setting your eyes on achieving sustainable urban living, investing in a rainwater tank is crucial. With a rainwater tank, you enjoy peace of mind, not worrying about water shortage problems caused by climate change. For this reason, rainwater tanks are becoming more popular, and this article has gone into detail about why getting one would deliver an excellent return on your investment.
