Water as ballast for tanks being buried in concrete

Water is a commonly used ballast material for tanks that are buried in concrete. This method of ballasting tanks has been utilized for many years due to its effectiveness and cost-efficiency. In this article, we will explore the reasons why water is chosen as a ballast material for buried tanks, as well as the advantages and disadvantages of this method.

One of the main reasons why water is used as a ballast material for tanks buried in concrete is its density. Water is a dense substance, which means that it can provide significant weight to the tank without taking up a large amount of space. This is important when burying tanks in concrete, as the weight of the ballast material helps to stabilize the tank and prevent it from shifting or moving. Additionally, water is readily available and relatively inexpensive, making it a practical choice for ballasting tanks.

Another advantage of using water as a ballast material for buried tanks is its non-corrosive nature. Water is not corrosive to most materials, which means that it will not cause damage to the tank or the concrete surrounding it. This can help to prolong the lifespan of the tank and reduce maintenance costs over time. Additionally, water is non-toxic and environmentally friendly, making it a safe choice for ballasting tanks that are buried in the ground.

Despite its many advantages, there are some drawbacks to using water as a ballast material for buried tanks. One of the main disadvantages is the potential for freezing and expansion. In cold climates, water can freeze and expand, which can put pressure on the tank and the surrounding concrete. This can lead to cracks or other damage, compromising the integrity of the tank. To prevent this, tanks that are ballasted with water may need to be equipped with heating systems or other measures to prevent freezing.

Another potential downside of using water as a ballast material is the risk of contamination. If the tank is not properly sealed or maintained, water can become contaminated with bacteria, chemicals, or other harmful substances. This can pose a risk to the environment and to human health if the contaminated water leaks out of the tank. Regular maintenance and monitoring are essential to prevent contamination and ensure the safety of the water ballast.

In conclusion, water is a commonly used ballast material for tanks that are buried in concrete due to its density, availability, and non-corrosive nature. While there are some drawbacks to using water as a ballast material, proper maintenance and monitoring can help to mitigate these risks. Overall, water is a practical and cost-effective choice for ballasting buried tanks, providing stability and support without compromising the integrity of the tank or the surrounding concrete.
