3 Advantages of Above Ground Water Storage Tanks

The storage tank or tanks are an important part of any rainwater collection system. And the dispute over the relative advantages of above-ground vs underground water storage tanks has raged for decades. Both have advantages and disadvantages, but this blog will concentrate on the above ground water storage tanks.

What Is the purpose of a storage tank?

While a rain harvesting system works when it rains, we need to store the water so that we may use it later. Even the most primitive systems in the past relied on the time-honored water butte located beneath the roof downpipe or a system of underground cisterns carved from solid rock, such as those created by the Romans. Purpose-built storage tanks are now both inexpensive and adaptable, making them an essential component of any rainwater harvesting system.

Common type of above ground water storage tanks

Plastic rainwater harvesting tanks, such as polyethylene tanks and GRP (glass reinforced polymer) tanks, are the most common today. Polyethylene (PE) is a low-cost, high-efficiency material that is used in everything from watering cans to water butts and big tanks up to 30,000 liters. GRP tanks can be pre-insulated if necessary, and they normally have a bigger capacity, up to 9,000 liters. For even more system storage capacity, GRP tanks can be constructed in a multi-sectional layout.

1. Maintenance is less difficult

Any fixture that is installed above ground level is obviously much easier to repair and maintain than one that is buried below ground level. However, they may be more subject to harm in particular circumstances. If properly installed and maintained, tanks, pipes, pumps, and other rainwater harvesting equipment should not leak, but if they do, leaks should be reasonably easy to discover and repair.

2. Ease of installation and expansion

Smaller PE storage tanks can be set up on the level ground, while bigger ones should be set up on a concrete or paved foundation. Because GRP tanks are less flexible and can shatter if they move, they will require a firm level base. If the system’s storage capacity needs to be increased in the future, adding another above ground water storage tank is relatively simple in most cases.

3. Space and variety

Above ground water storage tanks come in a wider range of sizes and styles than their underground counterparts. Tanks of this type come in a variety of sizes, shapes, and styles, ranging from plain spherical barrels to elaborate replica columns and even thin boxes designed to resemble fence panels. Because of the enormous variety, space is rarely an issue because there is always something that fits.
