Key Differences You Need to Know About Water Tanks

Installing water storage tanks on your property is a smart move because they have several advantages. But doing your research and making sure your chosen water tank can handle the particular difficulties on your property pays big dividends.

Types of Rainwater Tanks

  1. Poly (polyethylene)
  2. Fiberglass
  3. Concrete
  4. Metal

Poly Rainwater Tanks


  • Come in a wide range of sizes, shapes, colors, and combinations, as well as with several connection options. Both above and below the ground are options.
  • They are lightweight, making it simpler to move, place, or transfer them as needed. No large machinery is required.
  • Lightweight does not equate to frail. High-quality poly water tanks are made to withstand extreme weather and resist UV ray damage.
  • Flexible and simple to relocate.
  • Built as a single component, there are no seams to introduce weak areas.
  • 100% resistant to corrosion and rust.
  • Resists algae growth.
  • After metal, poly rainwater tanks are the second cheapest. But because poly outlasts metal, it is mo1re cost-effective.
  • Quicker, simpler, and less expensive installation. Poly is actually the simplest material to install among all water tank materials.
  • Non-porous.


  • Proper recycling is required at the end of their life cycle, which is known to be more than 30 years.
  • Plastic water tanks can, however, be reused for purposes other than water storage.
  • High fire risk : Unless they are in a fire break zone, most tanks, especially poly tanks, run the risk of failing in a fire just like any structure, pump, or piece of pipework would. What good was the tank if it survived your building?

Fiberglass Water Tanks


  • Fiberglass water tanks are available in a variety of sizes and functional both above and underground.
  • Similar to poly water tanks, non-porous.
  • Although fiberglass does not corrode, some parts can be vulnerable to localized corrosion.
  • Compared to concrete water tanks, it is simple to build.
  • Chemical resistance is a quality that poly and fiberglass both have.


  • Allows more light to enter, increasing the chance of algae growth.
  • Need a UV-resistant external gelcoat. Damage to this covering may shorten the tank’s lifespan.
  • Fiberglass is a very stiff substance. There are advantages and disadvantages to this.Although fiberglass does a good job of handling water pressure, with time its rigidity and inflexibility may give way to brittleness, causing leaks and cracks.

Concrete Water Tanks


  • Concrete tanks can be constructed above or below ground, come in a variety of sizes and capacities, and can either be pre-cast and delivered to the site or erected there.
  • Long-lasting.
  • Thanks to the concrete’s use of reinforced steel, have maximum strength.
  • Concrete doesn’t rust on its own. Sadly, the strengthening mesh does. See more below about this.
  • Excellent insulation qualities keep liquids or water colder.


  • Concrete water tanks require a lot of energy to manufacture, which raises the cost of construction and necessitates the use of more laborers and heavy machinery during installation.
  • Concrete water tanks are hefty and hence challenging to move.
  • Your plan needs to be revised to take the concrete tank into account if you’re planning to make alterations to your property.
  • Water tanks made of concrete are quite permeable.
  • Concrete tanks that have recently been built may leach lime or lend a taste to the water. pH in water is raised by lime. The water in the tank may be more likely to generate hazardous algae when the pH reaches an alkaline level.
  • Concrete pores, which are ideal for bacterial growth, can form. To lessen this probability, you could seal a concrete tank, but that would cost more.
  • Concrete tanks are prone to leaks and cracks.

Metal Water Tanks


  • They come in a variety of sizes and capacities and are resistant to extreme weather, including fire.
  • The substance is UV resistant.


  • Zinc is used to coat galvanized steel to prevent corrosion. In order to avoid the zinc from combining with the liquid contents and imparting a metallic flavor to the water, they are also sold with food-grade polyethylene liners. The liner may eventually need to be repaired if it breaks. Cleaning this kind of tank requires greater caution so as not to damage the lining.
  • Galvanized steel water tanks are less expensive than stainless steel water tanks, which are protected from corrosion.
