Types of Water Tanks and Their Uses

Water is a precious and globally dwindling resource – so it becomes the obligation of each of us to see that it is used responsibly, judiciously and in a way that minimizes waste. One thing that you can do is give some thought to the kind of water tank you buy; whether it is for home use, industrial use, agricultural use, whether you need pumps or pressure tanks or underground tanks.

We look at the different types of water tanks that you can buy.

Rainwater harvesting tanks

Rainwater harvesting is an ecologically and socially responsible thing to do. The rainwater collected can be used for various household chores and other uses. Rainwater harvesting can help to contribute to drinking water supplies and is shown to increase urban greenery and also help to replenish the underground water levels.


Rainwater harvesting tanks can help to lower municipal water bills for homes because it can provide water for gardening, flushing, washing and so on. With proper filtering systems, it is also possible to use the water for drinking purposes. Quality storage tanks also help to prevent mosquito breeding, contamination, growth of algae and to reduce the rate of water evaporation.

Plastic (polythene) water storage tank

There are several benefits of picking a water storage tank made from plastic or polythene. These can be light weight, and more easily portable when empty. This means that you have lower shipping costs and that you need to place less reliance on cranes for placing, fitting or moving of the tank.

The fact that plastic doesn’t rust is another huge plus point. Repair, upkeep and cleaning of plastic tanks may also be easier and cheaper than some other types of water tanks.

Galvanized steel and corrugated water tanks

Though plastic tanks can come in a variety sizes and shapes, when your water volume needs are higher, a plastic tank may not suffice. Generally speaking, plastic tank capacities do not exceed 15,000 gallons and in many cases this may not be enough.

Then of course there is the fact that the durability and strength of steel is far greater than plastic and other materials. Some types of steel tanks may also have lower environmental impact because of the manufacturing process used as well as their longer life.

Consider the pros and cons of each type of water tank as well as the possible ecological impacts, and consider your individual requirements before making a purchase.
