China Leading drinking water tanks Manufacturer

China Leading drinking water tanks Manufacturer

China’s demand for safe, reliable drinking water storage is growing rapidly, and Center Enamel—Shijiazhuang Zhengzhong Technology Co., Ltd.—has emerged as the country’s leading drinking water tanks manufacturer, serving municipal, industrial, and rural projects in more than 90 countries worldwide.

Proven Leader in Drinking Water Tanks

Center Enamel has built a strong global reputation as a leading drinking water tanks manufacturer, specializing in bolted steel tank technologies that combine durability, hygiene, and fast installation.

• Founded in 2008, the company has over 30 years of experience in the design and fabrication of Glass‑Fused‑to‑Steel (GFS/GLS) tanks, epoxy coated steel tanks, stainless steel tanks, galvanized tanks, and aluminum geodesic dome roofs.
• Its drinking water tanks are designed specifically for potable water storage, and are widely used in municipal water systems, agricultural projects, industrial facilities, and remote areas.
• Center Enamel’s tanks and manufacturing systems comply with key international standards for potable water, including ISO 9001, NSF/ANSI 61, WRAS, AWWA D103, and ISO 28765, ensuring safe and high‑quality drinking water storage in global markets.

With installations in the USA, Australia, Russia, Saudi Arabia, South Africa, Thailand, Brazil and many other countries, Center Enamel has demonstrated the ability to deliver drinking water tanks under a wide range of climatic and regulatory conditions.

Advanced Technologies for Drinking Water Storage

To meet the stringent requirements of potable water, Center Enamel offers two core bolted tank technologies: epoxy coated steel drinking water tanks and Glass‑Fused‑to‑Steel water tanks, both engineered for hygiene, durability, and performance.

Epoxy Coated Steel Drinking Water Tanks

Epoxy coated steel tanks are a flagship solution for municipal and industrial drinking water storage.

• Internal and external surfaces are coated with a specially formulated epoxy resin, forming a smooth, chemically resistant barrier that protects the steel from corrosion and prevents degradation of water quality.
• The epoxy coating is non‑toxic and food‑grade, certified to NSF/ANSI 61 and other potable water standards, ensuring that the stored water remains safe for human consumption.
• These tanks are engineered to withstand high internal pressures, seismic activity, and harsh environmental conditions, while requiring minimal maintenance over their service life.

Modular, bolted construction allows for rapid on‑site assembly and easy transportation, making epoxy coated tanks ideal for both large urban projects and remote or emergency water supply schemes.

Glass‑Fused‑to‑Steel (GFS/GLS) Drinking Water Tanks

Glass‑Fused‑to‑Steel tanks are another core technology used by Center Enamel for potable water storage.

• GFS tanks are manufactured by fusing a special glass enamel layer to steel plates at high temperature, creating a chemically inert, non‑porous, and highly corrosion‑resistant surface.
• This fused glass layer prevents rust, resists aggressive water chemistry, and minimizes the risk of contamination, making GFS tanks ideal for long‑term drinking water storage.
• Center Enamel’s GFS water tanks are designed to international standards such as EN ISO 28765, and have been widely used in potable water, industrial water, and irrigation projects worldwide.

The bolted design also enables rapid assembly and minimal site disruption, particularly beneficial for projects with tight schedules or in remote locations.^[9]

Hygiene, Safety and Compliance

For drinking water tanks, hygiene and regulatory compliance are paramount. Center Enamel designs its tanks and coatings to protect water quality throughout the asset’s lifetime.

• Potable water certifications: Epoxy coated tanks are produced in accordance with NSF/ANSI 61 and related ISO standards, while GFS tanks follow ISO 28765 and other potable water guidelines, ensuring that contact surfaces are safe for human consumption.
• Smooth internal surfaces: Both epoxy and GFS coatings create smooth, easy‑to‑clean surfaces that discourage bacterial growth and reduce sediment adherence, simplifying hygiene management and tank cleaning.
• Sealed roofs and accessories: Drinking water tanks are equipped with well‑sealed roofs—often paired with aluminum geodesic dome roofs—and properly designed hatches, manways and vents to keep out rainwater, dust, insects and other contaminants.

These design elements help utilities, industrial users and communities maintain high drinking water quality, even in challenging environments.

Fast, Flexible Installation with Bolted Designs

Center Enamel’s drinking water tanks leverage modular, bolted construction for fast installation and strong adaptability, a key advantage over conventional concrete or welded structures.

• Prefabricated steel panels are shipped in compact form and assembled on site with high‑strength bolts and gasket systems, significantly shortening construction schedules and lowering on‑site labor intensity.
• This approach is particularly valuable for emergency and disaster relief projects or infrastructure upgrades with tight deadlines, where rapid deployment can be critical.
• Bolted tanks can be expanded, relocated, or upgraded more easily than monolithic concrete tanks, providing long‑term flexibility as demand and network configurations change.

These characteristics make Center Enamel’s drinking water tanks suitable for both permanent infrastructure and temporary or mobile water supply installations.

Wide Range of Capacities and Applications

Center Enamel designs drinking water tanks with capacities ranging from tens of cubic meters to many thousands, allowing tailored solutions for projects of every scale.

• Municipal water supply: Bolted epoxy and GFS tanks serve as clear water reservoirs, distribution balance tanks, and elevated or ground‑level storage for city and town water networks.
• Industrial and commercial users: Factories, power plants, mining operations and commercial parks use these tanks to secure process water and domestic water for staff and facilities.
• Agricultural and rural projects: Drinking water tanks support irrigation schemes and safe water supply for villages and rural communities, where rapid installation and long‑term reliability are especially important.
• Emergency and disaster relief: Epoxy coated bolted tanks’ fast assembly makes them ideal for emergency potable water storage in post‑disaster or humanitarian operations.

This versatility ensures that Center Enamel can provide a consistent, high‑quality storage technology across very different project types and regions.

Global References and Project Experience

Center Enamel’s status as China’s leading drinking water tanks manufacturer is backed by an extensive portfolio of successful projects around the world.

• The company’s water tanks have been exported to over 90–100 countries, including the United States, Australia, Brazil, Russia, South Africa, Saudi Arabia, Thailand and many others.
• Glass‑Fused‑to‑Steel tanks from Center Enamel have been installed in large potable water projects, such as a 21,000 m³ GFS tank in Swaziland and similar large‑scale deployments in different regions.^[9]
• Epoxy coated steel tanks, designed in accordance with AWWA D103‑09, are in service in both urban and remote drinking water systems, demonstrating reliability under varied climates and operating conditions.

These global case histories confirm that Center Enamel’s technologies and quality systems translate into long‑term real‑world performance.

Sustainability and Long‑Term Value

Center Enamel’s drinking water tanks are not only technically advanced; they are also aligned with sustainability and lifecycle cost efficiency.

• Long service life: GFS tanks typically offer service lives of over 30 years, while epoxy coated tanks provide decades of corrosion‑resistant performance, reducing the need for frequent replacements or major rehabilitation.
• Low maintenance: The durable coated surfaces minimize maintenance, saving labor and avoiding prolonged shutdowns. Smooth internal surfaces also reduce the energy and water needed for cleaning.
• Reduced site impact: Fast bolted construction and compact transportation reduce site disturbance, noise and dust, supporting greener construction practices.

These features help municipalities and private operators build drinking water infrastructure that is both economically and environmentally sustainable.
