Today we are dealing with serious environmental problems, and the least we can do as responsible citizens is to minimize the damage we do to Mother Nature. If we want to be practical enough, we should use the fewest natural resources as much as we can and, whenever possible, solely rely on alternative renewable energy resources for our everyday needs. The technology available to us now is what is harming our planet, but one silver lining is, more and more people are using the same technology to find renewable resources that were never before used.

In the not-too-long-ago past, people have always relied on one readily available, renewable resource in rainwater. As we recognize the need to conserve the freshwater sources left on the planet, we should then turn our attention toward using rainwater again in our daily lives. In years past, people used clay pots and wooden barrels to store rainwater. Recently, a new method has emerged for the efficient collection of rainwater in an environment-friendly way—the rainwater collection system, including large and small rainwater tanks.

But why rainwater tanks? Why is it necessary to install rainwater tanks at home or on your premises? In today’s post, let’s discuss what you need to know about the effectiveness of rainwater tanks, as well as the benefits that they bring.

Why is installing a small rainwater tank a good move?

A very simple answer to this question is if your goal is to decrease your dependence on mains water supplies and decrease your monthly water bill. Rainwater tanks will help you with both. If you want a way around water interruptions caused by low water levels in your area, rainwater tanks will help you with this. Rainwater harvesting has existed for decades, and with the better technology available now, we can collect and store huge volumes of rainwater for longer, compared to harvesting and storing them in numerous vessels and rain barrels. This means the longer one household is independent of local water supplies, the more water this household saves.

It’s not always an easy decision when getting a rainwater tank, however. One concern with rainwater collection systems is the manner in which rainwater is collected and whether or not additional equipment will be needed to do such a task on your property. Plainly speaking, since gutters are standard in a modern roof structure, you’ll only need to acquire additional piping to connect your conveyance system (i.e., the gutters around your roof) to connect to your mode of storing water and a rainwater tank into which the rainwater is then stored for future use.

Another concern with rainwater collection systems and rainwater tanks is its initial cost. In the short term, the investment a household has to make is considerable, especially since rainwater tanks of all sizes and different materials and components—including installation and maintenance—will always be on the expensive side. In the long term, however, the rainwater collection system gradually pays for itself in the savings you earn from the monthly water bills and other fees that might be accrued as you continue to use main water supplies.

As you already have the initial equipment needed for collecting rainwater, your next logical move should be to invest in a rainwater tank.

Rainwater tank types

There are two main types of rainwater tanks—outdoor and indoor. Outdoor rainwater tanks can be built as independent structures from your home or built underground, but this might need additional piping and pumps to connect your gutters and divert water to your tank. The freestanding rainwater tank itself could harvest rainwater, and with the fewest moving parts, this means lesser maintenance is needed. However, you will have to buy additional screens and filters so larger physical debris like leaves and animal fecal matter cannot enter inside the tank structure. The most common rainwater tanks built outdoors are plastic, steel, and concrete rainwater tanks, and each material comes with its own advantages and warranty policies.

Since indoor small rainwater tanks are installed inside a house, an added bonus is the tank structure is protected from harsh weather conditions compared to outdoor rainwater tanks built and installed independently from the house’s structure. One caveat, however, since these tanks are indoors, the volume these tanks can harvest and the store is greatly limited by the size of the home. But since the tank is installed within the house, this also means the rainwater conveyance system can be connected directly to the tank as the tank is immediately under the roof gutters.

Of course, rainwater tanks are not cheap, but with the water, you save every day, over time, the rainwater tank pays for itself in terms of operating costs and convenience. With the many rainwater tank suppliers out there, you can easily find a tank that is perfect for your home and negotiate payment terms and warranty as well. However, it doesn’t hurt to compare prices and suppliers and see what other benefits and services they can provide. If you’re really serious about doing your part to help save the planet, installing a rainwater tank is that first serious step.
