A water tank for your property can be as simple as a rain barrel that you put outside to catch rainwater, perhaps even placing it at the end of your home's downspouts. However, for most homeowners, a water tank will be something they purchase and have placed underground or put in a convenient spot near their home, for holding as much water as possible in case of drought or fire. Before you buy a water tank for your property, note some important considerations; this will ensure you don't overspend on something you don't need and also understand what's involved with installing certain types of water storage tanks.
Is there a chance you'll move and need to take your water tank with you? Do you think you might do some renovations or landscaping in a few years and will need to change the location of your tank? If so, opt for something lightweight like wood or plastic. Fibreglass tanks are also lightweight, although usually they're the more expensive of all your choices. Steel tanks can be too heavy to move easily, and concrete tanks are a permanent installation.
2. Maintenance and durability
Wood rain barrels have been used for centuries since they're easy to make, but note that wood is prone to rot, mildew, termites, and the like. You would need to reseal a wood rain barrel regularly, and also inspect it for damage, warping, and so on. A concrete water tank is seemingly durable but note that it needs a liner so that the pressure of the water doesn't cause it to chip. If the liner were to get ripped or otherwise compromised, this can allow cracks to form in the concrete tank and the water to leak out. Remember this if choosing a concrete tank: that they're not as maintenance free as you might expect. Plastic and fibreglass are typically considered the most durable and most maintenance free options.
You may want a very large water storage tank to keep you protected in case of drought or fire, but consider how a large tank will be installed. A large steel tank will usually need to be installed by a professional, as is true with pouring a concrete tank. Even lightweight plastic or fibreglass tanks can become heavy and cumbersome if you choose the largest size available. Be sure you consider the cost of professional installation and any fabricating needed for a steel tank or for pouring a concrete tank when considering which is the right choice for your home.
