Plastic water tanks are utilized in a wide range of industries, such as the agricultural, oil and gas, water, waste treatment, medical, scientific, and pharmaceutical industries, over metallic water tanks. In addition, water tanks are often used for applications such as storing drinking water for residential and commercial installations as well as storing rain water.

They are also commonly used for applications such as fire protection, water treatment, agricultural irrigation, and other water-related purposes. However, plastic water tanks offer some disadvantages including low fire-resistance and high heat-absorbance, which can affect the temperature of the stored water. Still, while plastic water tanks are a recent alternative to metal, as they have only been in production for the last ten years, they are quickly becoming the preferred option.

Water tanks can be fabricated from a wide variety of plastic materials. Some of the most common types of plastic materials used to form water tanks are polyethylene and polypropylene. Polyethylene (PE), a light, chemical-resistant thermoplastic, is the most commonly used plastic for water tanks due to its strength and structural variability since it can be offered as high density polyethylene (HDPE), low density polyethylene (LDPE) and many more types.

However, other plastic materials, including polypropylene (PP), polyvinyl chloride (PVC), and polyvinylidene fluoride (PVDF), are durable, reliable options as well. Water tanks differ in size and capacity, ranging from small tanks holding a few gallons to tanks exceeding 35 feet in length, with a storage capacity of 50,000 gallons or more. The structure of the water tank varies.

Common tank shapes include cylindrical, square, rectangular, hexagonal, and octagonal. The heads and bottoms of water tanks also differ, according to their functions. For example, conical bottom tanks, which resemble a funnel, allow tank contents to flow quickly to the bottom of the tank, promoting easy tank drainage. In addition, when large capacities of water are needed, multiple tanks may be plumbed together.
