A water tank is also fondly called rainwater tank, and rightfully so because of the function it plays. When it rains, it pours, and when you come to think of it, when this water is left to flood the streets, it’s wasted. Apart from that, it can also cause danger to those around the area as waterways become filled up. Had this excess rain water been collected, it could’ve been used to wash clothes, flush toilets, water the plants, for showering, and with a filtering system, as a drinking water as well.
So, to answer the question if water tanks are sustainable: yes, they are. They can significantly reduce a household’s demand for commercial drinking water. That said, there are so many advantages to installing a water tank system in your home, starting with the following:
- Water Tanks Can Significantly Reduce Water Bills
Because you’re now utilizing what nature is giving you when it rains, you’ll have water stored in your tank for household consumption. For as long as this isn’t used up, you’ll have to purchase commercial water from your local water supply company less. In fact, you may not even have to do so at all, especially on the rainy days. This can help you cut down on your bills. Rain is free, after all, and it’s a blessing you can take advantage of, rather than letting it dampen your day, quite literally.

- Water Tanks Can Produce Water For Domestic Use
One of the most common misconceptions about water tanks is that the water they produce isn’t safe for consumption—false.
Water tanks are installed by experts, who use state-of-the-art filters and pumps to ensure a smooth collection and flow of the collected water. Most importantly, these also filter the rainwater so that what goes out from the faucets is potable. As a result, you’ll have free and safe water to drink in your home all the time.
That said, having your own water tank makes you more eco-friendly as you’re utilizing a natural source of water for domestic use, and you’re not depleting any other resource.
- Water Tank Can Significantly Reduce Roof And Gutter Damage
Another reason why water tanks are sustainable is that they can also help prolong your roof’s lifespan. Roofing and gutter damage is reduced when water doesn’t stay stagnant. Instead of staying on the roof, it goes automatically through the water tank.
In fact, rainwater can be collected from almost any type of roofing, for as long as the tank is positioned properly.
Here are some metrics to follow:
- For garden irrigation:
- Use gutter outlets that fit into the underside of the gutter
- Collect roof material, except asbestos (if your home still hasn’t been cleared from it)
- Fit a leaf screen to the gutters
- For drinking water, you’ve got to be more stringent about the collection process. Be sure that you avoid areas such as:
- Where asbestos and other toxic materials might have gathered on your roof
- Where airborne toxins are most present if your house is near a factory
- Water Tank Size Is The Most Important Factor When Trying To Be Sustainable
Water tanks are expensive, but you can significantly reduce the cost when you only purchase the size that you need for your household. Typically, the goal for having a rainwater tank should be to reduce the demand for commercial water up to a hundred percent. That way, your household becomes sustainable when it comes to water usage.
To help you decide on a water tank size, these are the factors you’ll have to consider:
- The security of water supply you desire: If you don’t want to run out of this sustainable source of water, you’ll need a bigger tank.
- The functions to be supplied: The main function of water tanks varies per household. For instance, if you’ve got a swimming pool, then you’ll need a bigger tank than a household without one.
- The area of roof draining to the tank: These two elements should be proportionate to each other to maximize efficient collection.
- The average amount of water consumption in your household: This can be determined through your previous water bills.
- The local rainfall pattern: Obviously, if there’s not much rain the entire year, then you won’t be able to collect enough water, hence, a bigger tank can’t even get filled up.
Conclusion
This list of advantages should, by all means, convince you that if there’s something you should invest in for this year, it’s the installation of a water tank. But, be sure that you leave this job to the experts. For you to maximize its function and ability, it’s very important that this is properly installed, which means that the roof around it is also properly designed with the right downpipes. Most importantly, the tank location should be accurate as well.
