What is a Water Tank Called?

Definition and Purpose: Potable water tanks, also known as drinking water tanks, are specifically designed to store water that is safe for human consumption. These tanks are typically made from materials that meet strict hygiene standards, such as food - grade plastics (like polyethylene) or stainless steel. They are used in residential buildings, commercial establishments, and even in remote areas where a reliable source of clean drinking water is essential. For example, in a rural community with no access to a centralized water supply, a potable water tank can store water collected from a well or a rainwater harvesting system, ensuring a continuous supply of safe water for drinking, cooking, and other household needs.

Alternative Names: They may also be referred to as domestic water tanks when used in homes or drinking water storage tanks to emphasize their purpose of holding water suitable for human intake.

Definition and Purpose: Non - potable water tanks are used to store water that is not intended for drinking but can serve other purposes. This includes water for irrigation in agriculture, water for industrial processes like cooling in factories, and water for flushing toilets in buildings. These tanks can be made from a wider range of materials, including concrete, fiberglass, and lower - grade plastics, depending on the specific requirements of the application. For instance, a large concrete non - potable water tank on a farm can store rainwater collected from rooftops and use it for watering crops, reducing the reliance on groundwater or municipal water supplies for irrigation.

Alternative Names: Depending on their use, they might be called irrigation water tanks, industrial water tanks, or graywater tanks when used to store water from sources like sinks, showers, and washing machines (which can be reused for non - drinking purposes).

Definition and Purpose: Fire protection water tanks are crucial components of fire suppression systems. They store a large volume of water that can be quickly accessed in case of a fire emergency. These tanks are often required by building codes and fire safety regulations in many areas. They are typically made of durable materials such as steel or concrete to withstand high pressures and ensure the water remains available during a fire. For example, in a large commercial building or an industrial facility, a fire protection water tank can provide the necessary water to feed sprinkler systems and fire hoses, helping to control and extinguish fires before they cause extensive damage.

Alternative Names: They are sometimes referred to as fire storage tanks or fire - fighting water tanks to clearly indicate their role in fire protection.

Definition and Characteristics: Plastic water tanks are widely used due to their lightweight, affordability, and ease of installation. They are commonly made from polyethylene, which is resistant to corrosion, chemicals, and UV radiation. Plastic tanks come in various shapes and sizes, from small above - ground tanks for residential use to large, modular tanks for commercial and industrial applications. For example, a small plastic above - ground potable water tank can be easily installed in a backyard to store rainwater for watering plants.

Alternative Names: Depending on the type of plastic and the manufacturing process, they may be called polyethylene water tanks, rotational - molded plastic tanks, or blow - molded plastic tanks.

Definition and Characteristics: Steel water tanks offer high strength and durability. They are often made from galvanized steel to prevent rust and corrosion. These tanks can be used for both potable and non - potable water storage, as well as for fire protection. They are suitable for large - scale applications where a high - capacity water storage solution is required. For instance, a large steel fire protection water tank can be installed on the roof of a high - rise building to meet fire safety requirements.

Alternative Names: Galvanized steel water tanks is a common name used to describe this type, emphasizing the protective coating on the steel to enhance its lifespan.

Definition and Characteristics: Concrete water tanks are known for their robustness and long - term durability. They are typically built on - site for large - scale water storage needs. Concrete tanks can withstand high pressures and are suitable for storing both potable and non - potable water. They are often used in water treatment plants, large residential complexes, and industrial facilities. For example, a concrete non - potable water tank in an industrial park can store water for various manufacturing processes.

Alternative Names: They may be referred to as in - situ concrete water tanks to highlight the on - site construction method or precast concrete water tanks when they are manufactured off - site and then assembled at the installation location.

Definition and Characteristics: Above - ground water tanks are installed on the surface, either on the ground or on elevated platforms. They are relatively easy to install and maintain. These tanks come in various shapes and sizes and are suitable for both residential and commercial applications. For example, an above - ground plastic potable water tank can be placed in a residential yard to store water for daily use. They are also commonly used in rural areas where digging for underground installation is difficult or not feasible.

Alternative Names: Surface - mounted water tanks or above - ground storage tanks are other names used to describe these tanks.

Definition and Characteristics: Underground water tanks are installed below the ground level. They offer several advantages, such as saving space above ground and being less exposed to external elements. These tanks are often used in urban areas where space is limited or where aesthetics are a concern. They are typically made from materials like concrete, fiberglass, or high - density polyethylene that can withstand the pressure of the soil and groundwater. For example, an underground concrete non - potable water tank can be installed in a commercial building's parking lot to store water for landscape irrigation.

Alternative Names: Subterranean water tanks or buried water tanks are alternative terms used to refer to these tanks, emphasizing their installation location.

As a sourcing agent, when helping clients choose a water tank, the first step is to clearly define the intended use of the tank. If it's for potable water storage, prioritize tanks made from food - grade materials and ensure they comply with relevant hygiene standards. For non - potable uses, consider factors like cost - effectiveness and the compatibility of the tank material with the water's chemical composition.

The installation location and available space also play a significant role. In urban areas with limited space, underground tanks might be a better option, while in rural or spacious areas, above - ground tanks can be more practical and cost - efficient. Material selection is crucial based on durability, maintenance requirements, and budget. Plastic tanks are a great choice for those on a tight budget and looking for easy installation, while steel and concrete tanks offer long - term durability for more demanding applications. Don't forget to factor in local regulations, especially for fire protection water tanks, to ensure compliance. By carefully considering these aspects, you can source the most suitable water tank that meets your specific needs and requirements.

When choosing between plastic and steel water tanks, consider factors such as cost, durability, maintenance, and application. Plastic tanks are generally more affordable, lightweight, and resistant to corrosion and chemicals, making them suitable for residential and many commercial applications. They require less maintenance as they don't rust. Steel tanks, on the other hand, offer high strength and durability, especially for large - scale or industrial uses. However, they may be more expensive, heavier, and need protection from rust through galvanization or other coating methods. Think about your budget, the tank's intended use, and the environmental conditions it will be exposed to when making a decision.

In most cases, underground water tanks are more expensive to install. The installation process involves excavation work, which can add significant costs, especially if the soil conditions are difficult or if there are underground utilities to work around. Additionally, underground tanks need to be properly sealed and protected from soil pressure and groundwater, which may require additional materials and labor. Above - ground tanks, on the other hand, are relatively easier and cheaper to install as they simply need to be placed on a prepared surface. However, the overall cost also depends on the size, material, and complexity of the above - ground tank installation.

Converting a non - potable water tank for potable water storage is not recommended without proper modification and testing. Non - potable water tanks may be made from materials that are not suitable for storing drinking water or may have been exposed to contaminants that are difficult to remove completely. Even if the tank is cleaned thoroughly, there could still be residual substances that pose a health risk. If you need a potable water tank, it's best to invest in a tank specifically designed and certified for storing drinking water to ensure the safety of the water.
