Water storage tanks are essential structures in every water supply system and a go-to solution in India for water storage. These tanks are carefully manufactured using specific design, distinct build and coating material to withstand the various environmental conditions.

These tanks come in different build-material such as plastic, fibreglass and steel. Not just that, they come in different shapes, sizes, colours, and varying sepcialities. In this article, we will talk about 5 important things that you need to keep in mind while choosing your next water storage tank.

Let’s dive deep right into it!

  1. Storage Capacity

The water tank’s storage capacity is one of the most important factor to consider while buying one. A water tank’s capacity depends on the number of people who rely on the usage of water on a daily basis. According to the Indian Standard Code, a person consumes 135 L of water daily on an average. A small tank of 650 L is enough for a family of four, whereas a large water tank is always advisable for larger households.

  1. Durability

The durability of a water tank is vital because it must be solid and powerful enough to endure variations in temperature and climatic changes. The material used for manufacturing a water tank is also important to ensure that it does not rust easily.

Plastic water tanks are the most commonly used storage tanks. They have several beneficial characteristics, including a smooth finish, lightweight, and affordable costs as compared to steel, fibreglass, or concrete water tanks. Plastic water tanks are classified based on their layers. Let us check how this factor helps you in finding an ideal water tank for your requirements.

  1. Layers

Maintenance is important to keep the water safe for consumption. Adding many layers is a common option for reducing operational hassle. The division of layers in a water tank range from single to six layers.

  • Single Layered Plastic Water Tank: These are single-layered polyethene, making them not suitable for UV protection. Prolonged sun exposure causes algal development in water tanks, particularly causing health hazards. These are rated as poorer grade water tanks as compared to double, triple, and four-layered tanks.
  • Double Layered Plastic Water Tank: These storage tanks have two layers of plastic making them suitable for UV protection. Double-layered tanks are undeniably superior to single-layered ones but fall short of triple or four-layered ones. These are the most cost-effective tanks for water storage.
  • Triple-Layered Plastic Water Tank: The first layer in a triple-layered water tank serves as the outer layer, the second layer provides protection from sun damage, and the third layer improves visibility. These tanks are highly durable, corrosion and rust-resistant. Made up of plastic, these tanks are leak-proof and unline single or double layered water tanks, they provide protection from UV rays.
  • Four Layered Plastic Water Tank: The 4-layer water tank is made of three layers of polyethene, and the remaining layer is made of Poly Urethane Foam. The foam coating improves the resistance to tolerating the hot and cold conditions outside.
  • Five Layered Plastic Water Tank: What makes the 5-layer water tank different from other layered tanks is its antimicrobial layer. The first and the second layers work as a protective and safety shield, respectively., The third layer offers protection from UV rays, and the fourth layer is accompanied by a foam coating. The fifth layer which is an antimicrobial layer provides protection against microbes and harmful bacteria.
  1. Brand

When investing in a water tank, the most important criterion is to opt for a reliable brand. Investing in a tank from a reputed manufacturer has many advantages such a better warranties, standard quality and good customer service.

  1. Colour And Shape

Selecting the right colour helps prevent the growth of germs. Bacterial growth develops in tanks which are light coloured because sunlight penetrates through them. It is advisable to go for black-coloured tanks since they block out the rays and minimise the growth of bacteria and other germs.

Water tanks come in various shapes ranging from spherical to cylindrical etc. It is best to select a tank based on where you will install it. For example, rectangular and square tanks save space by fitting easily in corners.

We hope this article meet all your queries regarding different types of water tanks. Remember that several aspects need to be considered while purchasing a water storage tank. Right from its size and capacity to the types and durability, all the factors help in deciding an ideal water tank for your needs.
