Advantages of polyethylene water tanks

High quality ‘plastic’ or polyethylene water tanks and chemical tanks have a number of advantages over equivalent fibreglass tanks and steel tanks. The article below mentions some of these. Please note that these advantages only apply to high quality polyethylene tanks such as those manufactured by JoJo Tanks in South Africa. A cheap, poor quality poly tank cannot be compared against steel & fiberglass tanks. Remember that, like so many things, you get what you pay for when it comes to choosing between the various poly tank brands on the market.

Ease of Handling and Installation

Since poly tanks are relatively light in weight and are extremely durable, transporting them is easy. Polyethylene tanks ship using basic freight methods such as common carriers and flatbed tractor trailers. Fiberglass tanks have special handling requirements, and because poly tanks are lighter than steel tanks, freight is cheaper. Additionally, when the tank arrives at your location, it can be offloaded using techniques and equipment commonly available at a jobsite. Lastly, they can be maneuvered multiple times until they are ready to install without fear of damage. All these factors make getting and installing your water tank or chemical tank much easier.

Ease of Maintenance

Unlike tanks made of other materials, poly storage tanks require almost no maintenance. Steel tanks require external preventive care such as painting and internal inspection to determine weld integrity. Fiberglass also poses its own issues, like multiple layer construction and the sensitivity toward micro-cracking. Poly tanks eliminate the need for internal inspection for leaks and cracks.

Leak Resistant

Rotational-moulded polyethylene storage tanks are leak resistant because they are moulded, one-piece construction without seams. Steel tanks tend to develop pin leaks over time from rust and corrosion and have stress points at welds. The quality of fiberglass tanks and their resistance to leaks can vary widely due to the method of construction and quality of the manufacture. The seamless construction and superior inert qualities of polyethylene tanks means less chance of leaks.

Lifetime Cost Effectiveness Polyethylene Storage Tanks

In addition to reduced cost to transport, less error-prone installation and reduced need for maintenance, poly tanks can sometimes last longer than steel and fiberglass tanks.

When considering a storage tank, keep these three important factors in mind:

  • Proper installation is critical to maximizing storage tank life.
  • Reducing potential leak points reduces the ongoing responsibility and cost of storing chemicals.
  • Tank material will determine the lifetime cost of a tank.

In the end, the advantages of high quality polyethylene tanks may make your choice an obvious one.
