In the global industrial and municipal landscape of 2026, the initial stage of any water treatment or distribution system relies on a single, critical component: the ability to store untreated water securely. As the first line of defense in the water cycle, Raw Water Storage Tanks have evolved from simple holding vessels into highly engineered assets that determine the efficiency, safety, and longevity of downstream purification processes. Whether the source is a natural river, a deep-well aquifer, or a rainwater harvesting system, the quality of storage at this early stage dictates the success of the entire water management journey.
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a globally recognized China Raw Water Storage Tanks manufacturer, is at the forefront of this engineering evolution. By integrating proprietary Epoxy Coated Tanks technology with the structural advantages of Aluminum Dome Roofs, we provide modular Water Tanks that are specifically designed to handle the challenges of raw water—ranging from abrasive silts and varying pH levels to environmental contaminants. With a proven track record in more than 100 countries, Center Enamel delivers the infrastructure that powers industrial production and municipal reliability worldwide.
In a modern water treatment facility, the Raw Water Storage Tanks perform several functions that go far beyond mere containment. Understanding these roles is essential for engineers and facility managers looking to optimize their operations in 2026.
Raw water sources are rarely constant. Rivers fluctuate with the seasons, and well pumps may operate on intermittent cycles to conserve energy. Raw Water Storage Tanks act as a hydraulic buffer, receiving these inconsistent inflows and providing a steady, controlled stream to the treatment plant. This stabilization prevents surges that could overwhelm sensitive filtration membranes or disrupt chemical dosing accuracy.
One of the most cost-effective ways to treat water is to let gravity do the work. Within the large volume of a Raw Water Storage Tank, heavy suspended solids, such as sand and silt, naturally settle to the bottom. This passive sedimentation reduces the turbidity of the water before it enters the treatment phase, significantly lowering the mechanical wear on pumps and extending the life of downstream filters.
In the event of a source failure—such as a broken water main or a contaminated intake—Raw Water Storage Tanks provide the necessary reserve to keep a facility operational. For many industrial sites, these tanks also serve a dual purpose as fire protection reserves, ensuring that a high-volume water supply is immediately available to suppress emergencies regardless of the status of the primary water source.
As a specialized China Raw Water Storage Tanks manufacturer, Center Enamel has moved away from traditional concrete and welded steel, which are prone to cracking and rapid corrosion in raw water environments. Instead, we utilize a modular bolted design enhanced by advanced materials science.
Raw water can be aggressive. Depending on its source, it may contain dissolved minerals, organic acids, or industrial runoff that can cause rapid pitting in standard steel. Our Epoxy Coated Tanks are engineered to resist these threats through a factory-controlled fusion process.
Fusion Bonded Epoxy (FBE) Shield: The coating is electrostatically applied and thermally cured, creating a dense polymer barrier that is molecularly fused to the steel substrate. This barrier is inert, meaning it will not react with the varying chemistries found in raw water.
Toughness and Flexibility: Unlike glass-fused-to-steel, which can be brittle, our epoxy coating offers superior mechanical resistance. It can withstand the minor impacts and structural flexes that occur during the filling and emptying of massive Raw Water Storage Tanks.
Edge and Bolt-Hole Protection: The most vulnerable points in any bolted tank are the edges of the panels and the holes for the fasteners. Center Enamel’s automated coating process ensures that these critical areas receive the same high-standard protection as the flat surfaces, eliminating potential points for localized corrosion.
In our specialized production facility, every panel used in our Water Tanks undergoes rigorous testing. This includes high-voltage spark testing to ensure that the coating is continuous and free of microscopic defects. By ensuring a holiday-free surface, we guarantee that the Raw Water Storage Tanks will provide a long service life with minimal maintenance requirements
To protect the raw water from external contamination and prevent biological growth, Center Enamel integrates Aluminum Dome Roofs into our storage solutions.
Algae growth is a major concern in raw water storage, as it can clog filters and impart unpleasant odors. Algae require sunlight to thrive. Our opaque Aluminum Dome Roofs block UV rays, naturally suppressing the growth of algae without the need for additional chemical additives. This makes the subsequent treatment process significantly easier and more cost-effective.
Raw water tanks are often the first point of entry for debris, birds, and insects. A geodesic aluminum dome provides a complete, sealed cover that prevents these external contaminants from entering the water. This is vital for maintaining the baseline quality of the raw water and protecting the integrity of the treatment system.
Traditional steel or wooden roofs are highly susceptible to rot and corrosion, especially in the high-humidity environment above a large water surface. Aluminum, however, is naturally resistant to corrosion. Once installed, an aluminum dome requires virtually no maintenance, providing a structural life that matches or exceeds that of the tank itself.
Being the leading China Raw Water Storage Tanks manufacturer means delivering more than just a product; it means providing a complete engineering solution that is accepted on the global stage.
Our Water Tanks are designed and manufactured in accordance with strict international standards, including AWWA D103-09, ISO 28765, and NSF/ANSI 61. This ensures that our tanks meet the safety and quality requirements of infrastructure projects in any region of the world.
Time is often the most critical factor in infrastructure development. Our modular bolted design allows Raw Water Storage Tanks to be shipped in standard containers and assembled quickly on-site. Because the assembly is done using specialized jacking systems and does not require extensive welding or heavy machinery, the tanks can be erected in a fraction of the time required for concrete or welded alternatives.
The reliability of Center Enamel’s technology is proven through successful installations in diverse industrial and municipal environments.
The Jiangsu Xuzhou Project is a testament to our capacity for large-scale infrastructure. As the primary China Raw Water Storage Tanks manufacturer for this project, Center Enamel provided the storage required to stabilize the intake for a major regional water treatment plant.
