Water tanks are an essential home addition because they preserve water, especially for rural areas. There is a variety of tanks available in the market, including the following:

1. Concrete water tanks

They are robust with longer lifespans. They are, however, heavy and difficult to carry and install because of their weight. They are usually underground tanks, but smaller concrete tanks can be installed aboveground. New concrete tanks, however, can leak lime into water, necessitating the need to flush it adequately before use. This type of water tank is associated with cracking and leaking. Their holding capacity can exceed 100,000 litres. Aboveground concrete tanks have the ability to keep water cool as they do not allow water penetration and resistant to algae growth.

2. Metal tanks

These type of tanks are made with a variety of metals usually steel. Steel is a good material for water tanks as they have the ability to store large volumes of water. They are available as a complete unit or assembled on site. Corrugated steel tanks come in a range of sizes and shapes and are customisable to fit your needs. Corrugated steel tanks are suitable for fire suppression or as a rainwater collection tank. The cons of a steel tank are that they still rust and corrode with time and are very expensive. They require the coating to prevent rust, which increases the cost.

3. Fibreglass tanks

This tank is rust- and corrosion-resistant. They are suitable for high-temperature areas as they are available in a number of coatings. Fibreglass tanks are usually aboveground tanks with a holding capacity of more than 150,000 litres. Fibreglass tanks do not crack or split and are lightweight and affordable. They are easy and cheaper to install.

4. Poly water tanks

Poly tanks have a range of applications such as clean water storage and rainwater collection. They are usually aboveground tanks but can work as underground tanks for septic purposes or storage of chemical waste. Poly water tanks are popular due to their weight, easy installation, durability and rust resistance. Poly water tanks come in a range of colours and shapes to fit your needs and available space. Their holding capacity depends on the size of the tank. The most common residential poly water tank is the vertical tanks that are for aboveground applications. They require installation on a level base and cannot be installed underground without concrete chamber walls.
