Considerations When Deciding on the Colour of Your Poly Tank

Image of a polyethylene tankPolyethylene tanks made using the process of rotational moulding are popular among most customers. One of the advantages of poly tanks is the broad range of colours available. Most buyers may pick a colour because of its aesthetic appeal and personal preference.

However, there are some reasons to think through the shade of your tank. Here are a few considerations.

Water Temperature

Dark coloured water tanks absorb heat, and they will heat up water at a faster rate compared to the lighter coloured ones. This may be significant if you want to save on water heating costs. However, high water temperatures offer a conducive environment for the growth of algae.

If algae growth is an issue for you, you can settle on mid-spectrum colours like green that will transmit light hindering the flourishing of algae.

Building Codes

Depending on the location of your building, the colour of your tank may be important. Some estates and business parks enforce building codes that allow only certain colours to be used. Find out if your area only permits the use of particular colours to ensure you do not purchase the wrong tank.


In places where there are multiple tanks in use, you might consider standardising specific colours for particular contents. In industries, for instance, you can use red containers to store hazardous products and white for a Poly water tank.

This is an important consideration in agricultural areas and wastewater management as well. Colour coding will enhance not only occupational safety for the workers but also proper handling of chemicals, food and waste.

In military camps where camouflage is essential, neutral colours are the ideal option. National parks and surrounding areas may opt for dull green, brown and khaki to blend in with the environment and prevent unpleasant eyesores.

You can now pick the best colour for your tank depending on your needs and surroundings.
