Costa Rica To Build A Quality Drinking Water Project
Created on 2024.03.23
High-Performance Potable Water Storage for Municipal Infrastructure in San Jose, Costa Rica
In regions facing water scarcity and contamination, the construction of reliable, safe drinking water infrastructure is a primary mandate for municipal stability. The government of San Jose, Costa Rica, recently addressed critical water supply shortages and groundwater contamination—including elevated arsenic levels—by integrating high-performance Glass-Fused-to-Steel (GFS) storage systems.
As a global leader in modular bolted storage technology, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) provided the engineering authority and technical containment solutions required to restore safe water access for local residents. Following the successful operational commissioning of this infrastructure in May 2026, the project serves as a model for utilizing advanced materials to solve complex regional water quality challenges.
1. Compliance Engineering: NSF/ANSI 61 and AWWA D103-09
Potable water containment requires a zero-leach threshold. Unlike standard storage vessels, Center Enamel’s GFS tanks are manufactured to meet the world’s most stringent municipal water safety standards:
● NSF/ANSI 61 Certification: This certification confirms that the GFS containment barrier is completely inert, preventing the leaching of heavy metals or synthetic chemical compounds into the stored drinking water.
● AWWA D103-09 Compliance: These tanks are engineered under the American Water Works Association (AWWA) D103-09 code, ensuring structural integrity under full-load hydrostatic pressure and resistance to localized seismic acceleration profiles common to the Central American region.
2. Advanced Material Science: Vitreous Enamel Passivation
The durability of the San Jose reservoir is rooted in a highly controlled, high-temperature thermodynamic process that molecularly integrates the strength of steel with the inertness of glass.
● High-Temperature Fusion: Steel panels are coated with proprietary silica glass frit and fired at temperatures ranging from 820°C to 930°C, inducing a chemical, molecular fusion.
● Corrosion Defense: This vitreous layer creates a non-porous, ceramic-like surface that is immune to atmospheric oxidation and internal water chemistry, ensuring a service life exceeding 30 years without the recurring maintenance costs associated with traditional liquid-coated steel.
● Custom R&D: Center Enamel’s dedicated R&D team tailored a specific enamel formula for the Costa Rica project, optimized for maximum chemical passivation and absolute safety in potable water containment.
3. Modular Engineering: Efficient Installation and Logistics
A primary challenge in municipal infrastructure is the logistical complexity of site assembly. Center Enamel’s modular bolted protocol provides a high-efficiency alternative to traditional construction:
● Rapid Deployment: Tank panels are precision-manufactured at the production facility and transported to the project site, where they are assembled using specialized high-tensile bolts and chemical-grade sealants.
● Low-Impact Assembly: The modular design eliminates the need for heavy, high-altitude scaffolding or massive on-site labor forces, allowing for faster commissioning compared to concrete or field-welded alternatives.
● Technical Oversight: To ensure compliance with global engineering standards, Center Enamel provided on-site installation guidance engineers, who trained local teams to manage the assembly, ensuring the project reached full operational status efficiently.
