Center Enamel successfully commissioned a high-capacity Glass-Fused-to-Steel (GFS) reservoir for a major municipal water project in Colombia. Engineered for NSR-10 seismic resilience and NSF/ANSI 61 purity, this installation provides a secure foundation for regional public health.
Colombia’s diverse topography—from the Andean highlands to coastal plains—demands rigorous structural integrity. Unlike rigid concrete reservoirs, which are prone to cracking during tectonic shifts, Center Enamel’s bolted steel tanks utilize high-strength carbon steel and flexible joint connections.
● Seismic Compliance: Our engineering team optimized the shell thickness and anchoring systems to satisfy NSR-10 (Norma Sismo Resistente), ensuring the water supply remains leak-proof even in earthquake-prone regions.
● Structural Dimensions: The reservoir measures 14.51 x 7.20 m, delivering a substantial 1,189m³ capacity with a modular footprint that preserves local land use.
In potable water storage, the internal coating is the primary barrier to contamination. Center Enamel utilizes advanced Glass-Fused-to-Steel (GFS) technology, thermally fused at over 800°C to create an inseparable molecular bond.
● Absolute Purity: Our coatings are strictly NSF/ANSI 61 and WRAS certified. This ensures zero leaching of heavy metals or chemicals, preserving the taste and safety of the municipal supply.
● Biostatic Surface: The glass-like finish is naturally non-porous and biostatic, preventing the attachment of biofilm, algae, and bacteria. This reduces the need for aggressive chemical dosing and simplifies long-term maintenance for municipal operators.

To eliminate "silent failures" common in field-painted tanks, Center Enamel applies a rigorous Non-Destructive Testing (NDT) protocol to every project:
1. 1500V Spark Test: We verify the dielectric strength of every panel. Testing at 1500V ensures a 100% pinhole-free barrier, preventing microscopic corrosion that could contaminate the water.
2. Vacuum Box Verification: Floor seams are verified via vacuum testing to ensure the reservoir is a hermetically sealed environment, preventing treated water loss and groundwater infiltration.
3. Pressure Integrity: The Aluminum Alloy Trough Deck Roof provides an airtight seal, protecting against dust, insects, and airborne pollutants.
Colombia’s terrain often limits access for heavy machinery. Center Enamel’s modular bolted design provided a decisive advantage for the 2022 project:
● 70% Shipping Volume Reduction: Components were flat-packed, allowing for cost-effective transport to remote sites via standard containers.
● Rapid Manual Assembly: The modular system eliminated the need for on-site welding or large cranes. Local crews used synchronized jacking systems, accelerating the project timeline and reducing the environmental footprint.
Q: Are Center Enamel tanks suitable for the high-humidity coastal regions of Colombia? A: Yes. Our GFS and FBE coatings are engineered for C4/C5 corrosive environments (ISO 12944). The fusion-bonded barrier is resistant to salt spray and high UV indices, preventing the "chalking" and peeling common in standard paints.
Q: How does the tank handle high UV radiation in highland regions? A: The Aluminum Alloy Trough Deck Roof effectively blocks 100% of harmful UV radiation. This is critical for preventing the growth of microorganisms that thrive in sunlight and can compromise water quality.
