Access to safe, clean drinking water is the most fundamental pillar of public health, community resilience, and sustainable development. For nations like the Philippines, an archipelago nation facing unique challenges including rapid urbanization, diverse geography, and vulnerability to natural disasters such as typhoons and seismic activity, ensuring a consistent and uncontaminated supply of potable water is a constant, critical endeavor. It is with immense pride and a deep commitment to global public health that Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) announces its pivotal contribution to the Philippines Potable Water Project. In 2023, Center Enamel successfully delivered and installed two monumental Drinking Water Storage Tanks as the cornerstone of this vital initiative. Each of these Drinking Water Storage Tanks boasts impressive dimensions of φ17.58m in diameter and 13.7m in height, providing a substantial capacity of 3340m³. Together, these two tanks deliver a combined storage volume of 6680m³ of essential potable water. These state-of-the-art tanks are further enhanced by highly durable Aluminum Dome Roofs, ensuring the pristine quality and continuous availability of the stored water for the communities of the Philippines. This project underscores Center Enamel’s position as a global leader and pioneer in providing high-performance bolted tank solutions that meet the most stringent international standards for water safety, hygiene, and infrastructure resilience.
For any nation, but particularly for a rapidly developing archipelago like the Philippines, strategic potable water storage is indispensable. The country's unique challenges, including a tropical climate, frequent typhoons, and active seismic zones, place extraordinary demands on water infrastructure. Drinking Water Storage Tanks in such environments must serve multiple critical functions:
· Absolute Purity and Hygiene: The paramount requirement is to prevent any form of contamination. This entails safeguarding against external pollutants (dust, debris, insects, airborne chemicals) and actively inhibiting internal microbial growth (algae, bacteria, biofilm). Crucially, the tank materials themselves must be inert, non-leaching, and approved for direct contact with drinking water, adhering to rigorous standards like NSF61 (National Sanitation Foundation/American National Standards Institute Standard 61 for Drinking Water System Components) and WRAS (Water Regulations Advisory Scheme).
· Corrosion Resistance: Given the high humidity and often coastal environments in the Philippines, exceptional internal and external corrosion protection is non-negotiable for long-term tank longevity. Corrosion can compromise water quality, lead to leaks, and drastically shorten a tank's service life.
· Structural Integrity and Seismic Resilience: These tanks must withstand immense hydrostatic pressures from thousands of cubic meters of water, alongside external loads from powerful typhoon winds and potential seismic activity. Their design must incorporate advanced engineering principles to maintain structural integrity without failure or deformation, even under extreme conditions.
· Long Lifespan & Low Maintenance: For sustainable infrastructure that serves communities for decades, Drinking Water Storage Tanks must be designed for an extended operational life with minimal maintenance requirements. This reduces lifecycle costs, ensures continuous service, and minimizes operational disruptions.
· Security and Accessibility: The stored water must be protected from unauthorized access or deliberate tampering, while also allowing for safe and efficient inspection, cleaning, and maintenance when required.
Center Enamel's Drinking Water Storage Tanks represent the pinnacle of storage technology for potable water, offering a multitude of compelling advantages specifically engineered for the rigorous demands of safeguarding drinking water, especially in challenging environments like the Philippines:
1. Ultimate Hygiene and NSF61/WRAS Compliance: The core advantage of GFS tanks lies in their unique coating. Each steel panel is coated with a two-to-three-layer vitreous enamel (glass) that is thermally fused to the steel This creates an incredibly hard, smooth, inert, and non-porous surface that forms an impenetrable barrier. This glass-like finish inherently prevents the growth of algae, bacteria, and biofilm, crucial for maintaining water quality without chemical interference. Center Enamel's GFS tanks are rigorously tested and certified to NSF61 and WRAS standards, providing undeniable assurance that they meet the highest international benchmarks for potable water components. This makes them vastly superior to porous concrete, internally lined welded carbon steel tanks, or fusion bonded epoxy tanks in terms of long-term hygiene for drinking water.
2. Exceptional Corrosion Resistance: The fused glass coating provides a superior, non-corrosive barrier that is impervious to water, chemicals, and environmental factors. This makes GFS tanks incredibly durable in humid, tropical, or even coastal environments, eliminating the need for internal lining re-painting or frequent maintenance associated with traditional steel tanks. They offer unparalleled resistance to rust and degradation.
3. Superior Durability and Longevity: The fusion of glass to steel results in a composite material that combines the strength and flexibility of steel with the chemical resistance and hardness of glass. GFS tanks are engineered for an exceptionally long operational lifespan, with minimal material degradation. This extended durability represents a significant long-term investment in sustainable infrastructure.
4. Leak-Proof Bolted Construction – Precision Engineered: Center Enamel, as the most experienced professional bolted tanks and covering manufacturer in Asia and the first manufacturer in China to produce GFS tanks, applies unparalleled precision in the engineering of these modular tanks. GFS panels are fabricated off-site under strict factory quality control conditions and then efficiently bolted together on-site using high-grade fasteners and specialized flexible sealants. This method creates a completely leak-proof structure, crucial for preventing water loss and safeguarding against external contamination, a common issue with cracking concrete or failing welds in welded carbon steel tanks.
5. Seismic and Wind Resilience: The bolted, modular nature of GFS tanks provides inherent flexibility, and they can be meticulously engineered with specific seismic design considerations (e.g., anchorage systems, flexible connections) to effectively withstand earthquake forces, a crucial factor for the Philippines' geological context. Similarly, their robust construction and Aluminum Dome Roofs are designed to endure the high wind loads associated with typhoons.
6. Cost-Effectiveness Over Lifespan: While the initial investment in a high-quality GFS tank may be higher than some temporary solutions, their extended operational lifespan, minimal maintenance requirements (no re-painting, no internal lining inspections), and prevention of water loss translate into significant lifecycle cost savings. This makes them a more economical choice over decades compared to stainless steel tanks for large capacities, or the recurring costs of maintaining traditional steel or concrete tanks.
To complement the robust Glass-Fused-to-Steel Tanks at the Philippines Potable Water Project, Center Enamel provided highly durable Aluminum Dome Roofs. The roof of a Drinking Water Storage Tank is as crucial as its shell, playing a vital role in safeguarding the stored water's purity and the tank’s overall integrity:
· Exceptional Corrosion Resistance: Aluminum alloy is inherently resistant to rust and atmospheric corrosion, making it an ideal material for long-term outdoor exposure in the humid, often coastal climate of the Philippines. Unlike steel roofs, it requires no painting or ongoing maintenance, ensuring a maintenance-free, long-lasting cover.
· Lightweight, Yet Structurally Robust: The geodesic design of Aluminum Dome Roofs provides an incredibly high strength-to-weight ratio. This reduces the overall load on the tank structure and its foundation, potentially simplifying foundation requirements. Despite their lightness, these domes offer superior resistance to environmental elements like high winds (typhoons), heavy rainfall, and seismic activity, ensuring the structural integrity of the entire storage system.
· UV Resistance & Algae Prevention: Aluminum Dome Roofs effectively block harmful UV radiation from reaching the stored water. This is crucial for preventing the growth of algae and other microorganisms, which thrive in sunlight and can compromise water quality, clog distribution systems, and lead to unpleasant tastes or odors. By blocking UV light, the roofs actively contribute to maintaining the water's pristine condition.
· Maintenance-Free Longevity: Aluminum roofs do not rust, chip, or peel, virtually eliminating the need for periodic painting, inspections for corrosion, or repairs of the roof structure itself. This significantly reduces operational costs and ensures the tank remains in continuous service without interruption for roof maintenance.
· Airtight Seal: The precision-engineered design of Aluminum Dome Roofs creates an effective, airtight seal over the tank. This prevents the ingress of dust, debris, insects, birds, and other airborne contaminants that could compromise water purity, maintaining a hygienic internal environment.
