Factors to Consider When Installing an Underground or Aboveground Water Tank

aboveground tanks or underground tanks

Water shortages in Australia have led to many people turning to water tanks for water storage. Apart from the water provided by utility companies, some have started harvesting rainwater and storing them in water tanks.  However, some people find it hard to choose the type of water tank they should install. The following are things you should consider when choosing whether to install an aboveground or an underground water tank.

1. Space Available

The space you have in your home is essential in determining the type of water tank to install. If you have a lot of space, you can go for an aboveground water tank but if your space is limited, an underground water tank would be ideal. When a water tank is below the ground, space above can serve other purposes like parking or a play area for the children. On the other hand, space occupied by an above ground tank is cannot serve any other purpose.

2. Environment around You

If you live in an area where you experience extreme weather conditions, it would be better to consider an underground water tank. Aboveground tanks are vulnerable to damage from the elements. Long exposure to ultraviolet rays damage the tanks and affects the quality of water. Moreover, water stored on aboveground tanks may freeze during the cold season and become uncomfortably hot during the summer. Tanks that are above the ground are also prone to human damage as they are accessible and visible to everyone. Plastic water tanks are most vulnerable as extreme heat can lead to cracks on the tank.

An underground tank is protected from harsh weather elements as it is completely covered below the ground. It is not affected by heat as water in an underground tank maintains cool temperatures at all times.

3. Maintenance

Aboveground water tanks are easy to repair and maintain as they are easily accessible. Underground tanks, on the other hand, pose a challenge when they need maintenance. However, since their construction is made with durability in mind, they rarely need repair or maintenance.

4. Installation

Installing an aboveground tank is not as complicated as underground tanks. An underground tank needs excavation and extensive concrete work if you want a concrete tank. Moreover, when considering the benefits of installation, aboveground tanks can deliver water using gravity especially if they are a few metres above the ground. However, when using underground tanks you have to use a pump to get water into your preferred places.

5. Cost

Since aboveground tanks do not require much to install, they are cheaper than underground tanks. If you intend to install a concrete underground water tank, be ready to spend much more for it.

If your current residence is permanent and you have no intentions of moving from the house, an underground tank is the best option for storing and harvesting rainwater. Although it will cost you more to install, it an expense that you will incur once since the tank is durable. In case you need installation of a water tank, be certain to contact a professional. Watertank installation is an intricate process that requires expertise. Get the best value for your money by having a quality tank professionally installed in your home. Install a water tank in your home and start reaping the benefits.

6. Type of Tank

There are different types of in-ground tanks. Depending on your needs and the space available, you can either go for a concrete, plastic, or metal tank. If you’re storing water for domestic use and you have enough space in your property, a concrete tank would do. Concrete tanks are not only long-lasting but also versatile. They can extend to any size and assume any shape. Additionally, they keep the water cool despite high temperatures above the ground. 

If you’re planning to construct a small tank, a plastic one will do as plastic tanks come in a variety of shapes and sizes. While metal tanks can manage pressure below the ground, they undergo corrosion when exposed to water, leading to contamination.

7. The Type of Water You Want to Store

Homeowners use underground tanks to harvest rainwater for home use or irrigation. However, these tanks can also be used for industrial purposes whereby wastewater is drained into the tank. If you’re installing in groundwater tank for wastewater, ensure it has insulation to avoid corrosion. Farmers looking for permanent water storage can install an underground concrete tank as it can hold more water. Since concrete tanks require minimal maintenance, they’re the best choice for long-term purposes

8. Type of Soil

If the type of soil in your property retains water for long, avoid installing a metal tank as dirty water can seep through the seams. For this type of soil, consider installing a plastic or concrete tank, as they’re impermeable. As such, the stored water doesn’t get contaminated, which makes it unsuitable for home use. 

9. Duration of Residence

Before installing an underground tank, you should consider the duration you intend to stay in your current residence. If you’re only there for less than two years, it’s not advisable to install a concrete tank. In this case, a plastic tank would be the best option, as you can easily excavate it and move it to another location. Concrete tanks are suitable for property owners who want to store water for long-term use.
