Different types of water tank in India

India has a historic background related to water storage and the uses of unique styles of tanks right from the Harappan civilization to the modern age. The Indus Valley Civilization was one of mankind’s first human settlements along the river Indus. The birth of this civilization was through the water of the river that nurtured the entire ecosystem around it. There is archaeological evidence showing water storage wells, tanks and brick lining structures. India has varied topographies and terrains, for the arid regions the underground storage of water system was developed to conserve water during summer droughts. These were called Tanka, Kunds and Kundis. The first ever known Kund was built by Maharaja Sur Singh in the village of Vadi Ka Melan dating back to 1607.

There are also instances of Horizontally dug water tunnels in Delhi during the Sultanate reign. There are lessons from these ancient water storage ways which were taken ahead as the centuries passed to what it is today. Here are some of the types of water tanks that we see in India.

1. Overhead Tank (on the roof)

These are most commonly found across India. Households in India are always incomplete if they don't have one overhead tank near their house. Whether it’s a building terrace, bungalow setup or just any location which needs water storage. You are sure to find such tanks that provide water to the people under it. These are generally made of Polyethylene plastic and are great for budget conscious buyers. Since it is exposed to daylight and sun rays, they are dark colored to prevent any algae growth.

2. Fiberglass Water Tanks

Fiberglass is a material that is non corrosive. Which means they will never rust. This quality makes them perfect for oil storage in liquid form. They can hold anywhere between 250 to 50,000 gallons of substance. In India the Tanks which are FDA approved are considered to be more durable. These tanks also come in aboveground variants which are best suited for storage of chemicals as they are double walled tanks too customized for volatile storage.

2. Ponds and storage pools

These medium to large sized open area ponds are an easy way to store free falling water that is runoff from rains. The natural way of the pond solution storage is that its quality retains with processes like soil filtration, sedimentation, decomposition and solar disinfection. The ponds are used for fishing cultivation, animal husbandry and even irrigation.

The versatility of Fiberglass water storage tanks also makes them ideal for fire protection systems. The duality of these tanks has wide range from quick access in controlling fires to storing potable water for later use.

As opposed to concrete these tanks are lightweight, so the operational costs are lowered to move and locate these tanks in a fixed position. Since these tanks are used in high volatile risk industries, they are built for absolute leak proof performance. Their watertight design is critically approved by many professionals as perfect for such factories and chemical pro stations.

Apart from tanks, this material - fiber reinforced thermoset resin composites (fiberglass or FRP) is used since decades for pipelines and ducts and exhaust systems. The retail and petroleum industry highly demand the use of these tanks in India.

3. Stainless Steel Water Tanks

The biggest advantage of these tanks is that they are maintenance free. They are designed for excellent efficiency by Japanese technology innovations. Stainless steel tanks are made for the food industry primarily so they keep the food grade material preserved as it is. Light is completely blocked away from the stainless steel so there are no chances of corrosion or algae growing making the tanks very hygienic.

All the processes of building the actual tank are already integrated. So the tanks are easy to install for any given suitable location you wish to place these tanks in. Although this work needs to be under the supervision of highly trained and skilled professional nonetheless.

4. Carbon welded steel Tanks

These tanks are generally less expensive compared to the fitted steel tanks as counterparts. Carbon steel is made from carbon which is the main alloy material. The percentage of carbon content determines what quality the tank really is. Based on this property of the carbon, you can customize your carbon welded steel tanks into different storage categories. With the rise in carbon content the brittleness lessons and the ductile quality heightens.

As with stainless steel, carbon steel also produces high durability and major non corrosion resistance. The Indian industries particularly relating to construction work and applications use these tanks.

5. Bolted Steel Tanks

If the will to increase capacity for a concrete or welded steel tank arises, the only option is to not upgrade the tank due to huge expenses foreseen as they are not flexible. Bolted tanks however on the other hand are extremely flexible in expanding or upgrading already existing steel tanks without much labour. Minimum energy and time required to fit the new capacity bolded tank due to its swift installation process.

They are multi purposes tanks used in many industries like agriculture, manufacturing and fire drill protection. As they are huge in gallon intake, they are also used in animal husbandry and grain storage activities.
