How Long Do Concrete Water Tanks Last Ideally?

How Long Do Concrete Water Tanks Last Ideally?

  Monday 31st January, 2022

Concrete Water Tanks and other tanks generally last for a long time with a useful life of over 15 years on minimal maintenance.

Typically speaking, the practical lifespan of a tank is dependent on the following aspects:

  • Underground v/s above ground positioning of the tank
  • Material of the water tank
  • Type of water tank

In this blog, we’ll delve into how these factors influence the lifespan of a water tank and emphasise specific instances to illustrate the points mentioned above.

Concrete Water Tanks Life Span

Positioning Of The Water Tanks

There are commonly two positions for a water storage tank: underground and above the ground. An underground tank is any tank and connecting piping that carries at least 10% of its combined volume below ground. Underground tanks are usually installed to maximise the available land use and store large amounts of water.

Tanks above ground (typically, Concrete Water Tanks) are ideal for people trying to minimise the cost of installing a tank since they don’t need excavation or backfilling fees. They are easily accessible and can be easily repaired.
In general, underground water tanks last longer than above-ground water tanks because above-ground water tanks are more prone to damage from environmental aspects.

Material Of The Water Tanks

Tanks are usually made from corrugated steel, plastic or concrete. This has a bearing on the tank’s life as some materials are more durable than others.

A typical plastic water tank is made of high–density polyethylene, whereas Concrete Water Tanks are made of ferrocement or reinforced cement. Generally, cement tanks are more durable than their counterpart plastic water tanks. However, on the other hand, Concrete tanks are prone to rust. But, during natural disasters such as cyclones, plastic water tanks may get dislocated or easily damaged.

Type Of Water Tank

Tanks come in several shapes and sizes depending on an individual’s needs, but here we highlight various types of tanks with their respective useful lives:

  • Corrugated Steel Tank made of Galvanised Steel: Over 20 years
  • Welded Steel Tank made of Carbon Steel: Over 20 years
  • Fibreglass Tank: Over 20 years
  • Poly Tank: Over 20 years
  • Concrete/Cement Water Tank: 15+ years
  • Onion Tanks made of Reinforced Polyvinyl: 3 months to 5 years

Perhaps the most appropriate tanks for water storage would be the fibreglass water tanks, poly (plastic) water tanks, Concrete tanks, and onion tanks.

Bottom Line

There is a wide variety of water tanks from which one could choose from. For example, Bega Tanks offers water storage tanks that may fit anyone’s needs from a possible short–term life of 3 months to a long–term useful life of over 25 years. So now that you know what affects the life of your water tank, you should be able to make the appropriate choice.
