Why Glass-Lined Water Storage Tanks for Drinking Water?

The unique construction of Glass-Lined (GFS) tanks combines the strength of steel with the corrosion-resistant properties of glass. This results in a storage tank that offers outstanding durability, corrosion resistance, and hygiene—essential qualities for drinking water storage. Center Enamel’s glass-lined tanks are specially designed to prevent contamination, withstand harsh environmental conditions, and provide safe, secure storage for potable water.

Advantages of Center Enamel’s Glass-Lined Water Storage Tanks

Unmatched Corrosion Resistance

The glass coating provides an impermeable barrier, effectively shielding the steel substrate from corrosion. This ensures long-lasting durability, even in highly corrosive environments, and protects the purity of the stored drinking water.

High Hygiene Standards

The smooth, non-porous glass surface resists bacterial growth, ensuring a hygienic environment for drinking water storage. This feature helps prevent contamination and supports strict health and safety standards.

Strong Structural Integrity

The fusion of glass and steel creates a tank with high structural strength, capable of withstanding extreme weather conditions, seismic activity, and heavy loads. This makes it ideal for large-capacity water storage projects, ensuring stability and reliability over many years of service.

Easy Cleaning and Maintenance

The glass-lined surface makes the tanks easy to clean and maintain, as the smooth finish prevents the accumulation of sediments and impurities. This minimizes maintenance requirements and extends the tank’s service life.

Adherence to Global Standards

Center Enamel’s GFS tanks are designed and manufactured to meet AWWA D103 standards and comply with OSHA safety regulations. This compliance guarantees that our tanks meet the highest quality, performance, and safety standards, essential for large-scale drinking water projects.

Key Features and Technical Specifications

Advanced Glass Coating Process

Our glass lining is applied using a controlled, high-temperature process that bonds the glass to the steel at a molecular level. This creates a highly resistant surface that remains intact even under thermal and pressure fluctuations, ensuring both durability and leakproof performance.

Precision Engineering and Customization

Center Enamel provides tailored tank sizes and capacities to suit project-specific needs. Our tanks range in sizes from small municipal projects to large-scale industrial applications, all crafted to exact specifications with customizable features to meet diverse project demands.

Enhanced Sealing Technology

Using bolted steel technology, the panels are joined with high-quality sealants that further improve the tank’s leakproof properties, enhancing the safety and reliability of stored drinking water. The bolted design also facilitates easier installation and disassembly, ideal for projects that require relocation or expansion.

Compliance with AWWA and OSHA Standards

Our Glass-Lined Water Storage Tanks meet both AWWA D103 standards and OSHA regulations, ensuring that they:

Meet stringent health standards for potable water storage, providing a reliable barrier against contaminants.

Adhere to OSHA safety guidelines during installation and operation, promoting a safe environment for all personnel involved.

Undergo rigorous quality control and testing, which includes leak-proof tests, durability assessments, and structural integrity evaluations to guarantee long-term performance and safety.

Applications in Drinking Water Projects

Center Enamel’s glass-lined tanks are ideal for a wide range of drinking water storage projects, including:

Municipal water supply systems that require safe, large-capacity storage.

Industrial water storage applications where high standards of water purity are essential.

Rural and remote area water storage, where a robust and low-maintenance solution is necessary.

Emergency water storage for disaster-prone areas that need resilient and secure storage tanks.

Installation and Maintenance Benefits

Our bolted Glass-Fused-to-Steel tanks are designed for quick and efficient installation. The modular bolted design enables rapid assembly on-site, reducing construction time and costs. The tanks can also be disassembled and relocated as needed, adding flexibility to meet changing project demands.

Installation Process:

Foundation Preparation: The installation site is prepared with a stable, level foundation, typically concrete, to support the tank’s weight and ensure stability.

Tank Assembly: The bolted steel panels are joined with precision, creating a leakproof and structurally sound tank. Our expert team oversees the installation, ensuring compliance with AWWA and OSHA standards.

Accessory Installation: Inlet/outlet connections, valves, and other components are fitted to optimize the tank’s performance and facilitate easy monitoring and maintenance.

Environmental and Economic Advantages

Sustainable and Long-Lasting

The superior durability of glass-lined tanks means fewer replacements, resulting in a reduced environmental impact. Center Enamel’s commitment to sustainability is reflected in our eco-friendly production process, designed to minimize waste and maximize the longevity of each tank.

Cost-Effective Solution

By choosing glass-lined tanks, drinking water projects can reduce costs related to maintenance, repair, and replacement, ultimately enhancing the return on investment. The robust construction and corrosion resistance lower operational expenses over the tank's lifespan.

Scalable and Relocatable

The bolted design allows for easy scalability, making it possible to expand storage capacity as needed. Tanks can also be dismantled and reassembled in new locations, providing flexibility and reducing additional infrastructure costs.
