Why Choose NSF/ANSI 61 Standard Glass-Lined Steel Tanks for Potable Water Storage?

Glass-Lined Steel (GLS) tanks are increasingly becoming the preferred choice for storing potable water due to their unique combination of strength, corrosion resistance, and safe water storage capabilities. Specifically, when these tanks meet the NSF/ANSI 61 Standard, they offer the added assurance that the materials used do not leach harmful substances into the water, ensuring that the water remains clean, safe, and compliant with health regulations. Here’s why GLS Potable Storage Tanks with NSF/ANSI 61 certification are ideal for potable water storage:

1. NSF/ANSI 61 Certification for Safety and Compliance

The NSF/ANSI 61 standard is a rigorous certification that ensures the materials used in water tanks are safe for drinking water. This certification verifies that the tank's coatings, materials, and components will not release harmful chemicals or contaminants into the water, making them suitable for potable water storage. At Center Enamel, our Glass-Lined Steel Tanks are NSF/ANSI 61 certified, ensuring that they comply with international standards for safe drinking water storage.

2. Corrosion Resistance for Long-Term Durability

One of the most significant challenges for potable water storage tanks is corrosion. GLS tanks are designed with a glass coating that provides a non-porous, smooth surface that effectively prevents rust, scale, and other forms of corrosion. This glass lining ensures that the water inside the tank remains pure and uncontaminated, while the steel structure provides the strength and durability necessary for long-term use in various environmental conditions.

3. Non-Reactive with Water

The glass lining of our Glass-Lined Steel Tanks creates a barrier between the tank’s steel structure and the stored water. This prevents the steel from reacting with the water, ensuring that the water remains chemically stable and safe for consumption. The non-reactive nature of GLS tanks is critical for potable water storage, as it ensures that there are no unwanted interactions between the tank and the water, preserving the water’s purity and taste.

4. Smooth Interior Surface for Clean Water Storage

The smooth, non-porous surface of the glass lining not only resists corrosion but also prevents the buildup of biofilms, sediment, and other impurities that can affect water quality. This ensures that the stored potable water remains clean and fresh, with minimal maintenance required. The smooth interior also makes it easier to clean the tank when necessary, further enhancing its longevity and the safety of the water.

5. Strength and Reliability

In addition to its corrosion resistance, Glass-Lined Steel Tanks offer exceptional structural strength, making them ideal for large-scale potable water storage applications. The steel framework provides the tank with the strength necessary to withstand pressure from large volumes of water, while the glass lining provides an additional layer of protection against environmental factors. These tanks are designed to endure heavy use, including seismic activity, extreme weather conditions, and other demanding situations.

6. Cost-Effective and Low Maintenance

GLS potable storage tanks offer a highly cost-effective solution for storing drinking water. The combination of steel’s strength and glass’s corrosion resistance minimizes the need for frequent maintenance or repairs, ultimately lowering operating costs over the life of the tank. The durability of Glass-Lined Steel Tanks also ensures that they provide long-term value and dependable service, reducing the frequency of tank replacements.

Key Applications of NSF/ANSI 61 Certified Glass-Lined Steel Tanks

NSF/ANSI 61 Certified Glass-Lined Steel Potable Storage Tanks are used in a wide range of applications, providing safe and reliable storage for drinking water in many industries and settings. Here are a few examples:

1. Municipal Water Systems

Local governments and municipalities rely on Glass-Lined Steel Tanks to store potable water for public distribution. These tanks are designed to meet the high demand for water, providing large-scale storage while maintaining the water’s safety and quality. The NSF/ANSI 61 certification ensures that these tanks comply with the strict regulations for drinking water storage and distribution.

2. Industrial Water Systems

Industries such as food and beverage processing, pharmaceutical manufacturing, and chemical plants often require potable water for production processes and employee use. NSF/ANSI 61 certified tanks provide a reliable storage solution for industries that need to ensure the safety and quality of their drinking water for operational and compliance purposes.

3. Agricultural and Irrigation Systems

GLS potable storage tanks are also used in agricultural settings where water needs to be stored for irrigation and livestock watering. The tanks ensure that water remains clean and uncontaminated, even when used for agricultural purposes, thus maintaining water quality standards.

4. Residential Water Storage

Glass-Lined Steel Tanks are ideal for residential communities in need of safe and reliable potable water storage. These tanks can be used in water towers, water treatment facilities, or as part of private water supply systems for large housing developments or remote areas without direct access to municipal water.

5. Emergency and Disaster Relief Applications

In times of emergency or natural disasters, access to clean drinking water can become a significant challenge. NSF/ANSI 61 certified tanks are often used in disaster relief operations to store potable water and ensure that those affected by the disaster have access to safe drinking water. Their durability and corrosion resistance make them an excellent choice for these critical applications.
