Municipalities don’t always provide adequate water throughout the day, so a water storage tank that can give you a continuous supply of water is now essential for many households. Water tanks have become increasingly important, especially in rural areas where people might not have 24/7 access to water.
The tanks most readily available on the market are concrete, fiberglass and plastic. Many homeowners choose concrete, but is that the best option? This article will discuss better alternatives to concrete for underground water storage.
What Are Concrete Underground Water Storage Tanks and Why Are They a Poor Option?
Precast underground concrete water storage tanks are a popular option for many homeowners and businesses. They offer some advantages, including a low price compared with other options. However, concrete is a poor choice for an underground water storage tank for several reasons:
Yes, concrete is a sturdy material — but it’s also heavy. This can complicate and increase the cost of transportation and installation. Installers will need to use machinery to lift the tank into the desired location.
Plus, as concrete ages, it becomes more susceptible to cracks and erosion. This is because of its porous composition and because concrete slabs are often made from pieces poured at different times, creating more opportunities for cracks. Once concrete begins to degrade, it causes a series of problems — including leaks — that are difficult and expensive to fix.
Concrete tank leaks are not easy to repair, especially when it’s buried underground. Repairers may need to dig through the ground to reach the source of the leak, as the tank cannot be lifted out for fixing.
For these reasons, it is important to consider other options when choosing an underground water storage tank.
Alternatives to Concrete Underground Water Storage Tanks
Plastic Tank Advantages
Plastic tanks are often preferred over concrete for septic and water storage because they are lighter, watertight and cheaper to install. They are readily available in sizes from 250 gallons to 20,000 gallons, and they come in different configurations, such as round, rectangular and cylindrical.
Concrete tanks require heavy machinery for lifting and transport, but their plastic counterparts can be moved using simple tools like a dolly. This makes them especially beneficial in inaccessible areas where transportation costs would otherwise be high.
Plastic is more resistant to cracking, so you won’t have to inspect it as often. Made from a single piece of plastic, poly tanks don’t have any joints or sealed components that could break. They’re also completely resistant to water damage. So, whether you install it in damp soil or above ground in a humid climate, the plastic tank will never rust.
Although they are not prone to breaking, when plastic water tanks do crack, the fix is less complicated than you might believe. You simply apply heat and sealant to close the fracture. In some respects, plastic is more durable than concrete precisely because of its adaptability.
Fiberglass Tank Advantages
Fiberglass tanks offer many benefits and can be used for various purposes, including rainwater harvesting, water storage, fire protection, oil field storage, liquid fertilizer storage, water treatment and irrigation. They are designed to withstand corrosion, high temperatures and impact.
Fiberglass tanks can readily store between 1,000 and 50,000 gallons, and they can be customized for different uses and easily reconfigured or repaired as needed. They are cost-effective and easily customizable to meet the specific needs of your project. Most importantly, they are durable and long-lasting to give you peace of mind knowing that your tank is highly-reliable for years to come.
