Center Enamel:Turnkey Contractor for Singapore Municipal Sewage Treatment Project
In the strategic industrial landscape of 2026, Singapore has entered a critical phase of its environmental journey. Designated as the Year of Climate Adaptation, 2026 marks the culmination of decades of visionary planning by the Public Utilities Board (PUB). At the heart of this national resilience strategy is the Singapore Municipal Sewage Treatment Project framework, a sophisticated "super-highway" of used water management designed to ensure absolute water security for a growing population and a high-tech industrial base.
The jewel of this framework in 2026 is the Tuas Water Reclamation Plant (WRP), part of the revolutionary Tuas Nexus. As Phase 2 of the Deep Tunnel Sewerage System (DTSS) reaches full operational status, Singapore is transitioning to a three-node centralized system. This transition requires infrastructure that is not only durable but also incredibly space-efficient and energy-neutral. To meet these world-class standards, global partners and local authorities require a specialized Turnkey Contractor capable of delivering integrated, high-performance containment and treatment solutions. Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the brand Center Enamel, provides the engineering, procurement, and construction (EPC) expertise necessary to support Singapore's quest for 100% water circularity.
Product Definition: Engineering Excellence for Singapore's Urban Constraints
The success of a Municipal Sewage Treatment project in Singapore is fundamentally tied to land-use efficiency and structural longevity. In a country where land is the most precious resource, traditional expansive concrete basins are being replaced by vertical, modular, and high-performance containment systems. Center Enamel provides a sophisticated multi-material approach to ensure these municipal assets serve the nation for the next 50 years.

1. Glass-Fused-to-Steel (GFS) Tanks: The Vertical Advantage
Our flagship GFS tanks are the preferred choice for advanced sludge digestion and primary treatment in Singapore. By fusing high-tech glass enamel to specialized steel at temperatures exceeding 800 degrees Celsius, we create a surface that is chemically inert.
Corrosion Resistance: GFS is virtually immune to the high hydrogen sulfide (H₂S) environments common in municipal sewage tunnels and digesters.
Vertical Scalability: Unlike concrete, GFS tanks can be engineered with high aspect ratios, allowing for massive storage capacity on a minimal footprint—a critical requirement for Singapore's land-scarce environment.
2. Epoxy Coated Tanks: Specialized Utility Support
As a critical part of our infrastructure portfolio, Center Enamel Epoxy Coated Tanks provide a durable solution for auxiliary stages, such as equalization and treated water storage. These tanks utilize a high-specification electrostatic powder coating process that provides excellent resistance against industrial detergents and processed effluent, offering a cost-effective yet highly durable alternative for the utility phases of a Municipal Sewage Treatment plant.
3. Double Membrane Roof Systems: Powering Tuas Nexus
In 2026, Singapore's municipal plants are energy-neutral. Center Enamel integrates high-performance Double Membrane Roof systems onto anaerobic reactors to facilitate this.
Biogas Harvesting: These systems capture methane generated from sewage sludge and food waste.
Energy Self-Sufficiency: As a Turnkey Contractor, we ensure these roofs are airtight and integrated with biogas-to-energy units, contributing to the energy self-sufficiency of facilities like Tuas Nexus.
4. Aluminum Dome Roofs: Odor Control and Aesthetic Integration
Given Singapore's high urban density, municipal plants must be "good neighbors." Center Enamel provides specialized Aluminum Dome Roofs for primary clarifiers and storage tanks. These geodesic domes provide maintenance-free, clear-span coverage that contains malodorous compounds while presenting a clean, modern aesthetic that fits Singapore's world-class urban landscape.
Technical Foundations: Mastering the NEWater Cycle
As a premier Turnkey Contractor, Center Enamel masterfully engineers the containment solutions required for the multi-stage Municipal Sewage Treatment process that feeds into Singapore's NEWater production.
| Treatment Stage | Center Enamel Containment Solution | Function in the NEWater Cycle |
| Preliminary Treatment & Grit Removal | GFS and Epoxy tanks as critical staging points | Protect downstream Membrane Bioreactors (MBR) from abrasive particles; primary sedimentation |
| Advanced Membrane Bioreactors (MBR) | Specialized, corrosion-resistant tanks housing sensitive membrane environments | Support high-density MBR configurations combining biological treatment and microfiltration |
| Sludge Digestion & Resource Recovery | 40-meter-tall digesters with advanced mixing systems and Double Membrane Roofs | Maximize conversion of organic waste into biogas and biosolid fertilizers, embodying the circular economy |
1. Preliminary Treatment and Grit Removal
Municipal sewage enters the DTSS tunnels and is conveyed by gravity to centralized plants. Our GFS and Epoxy tanks serve as critical staging points for grit removal and primary sedimentation, ensuring that the downstream Membrane Bioreactors (MBR) are protected from abrasive particles.
2. Advanced Membrane Bioreactors (MBR)
In 2026, Singapore utilizes the world's largest MBR facilities. Center Enamel provides the specialized, corrosion-resistant tanks required to house these sensitive membrane environments. Our tanks are engineered to support the high-density configurations of MBR units, which combine biological treatment and microfiltration to produce high-quality treated used water.
3. Sludge Digestion and Resource Recovery
The sludge generated during treatment is processed in 40-meter-tall digesters. Center Enamel's turnkey expertise ensures these digesters are equipped with advanced mixing systems and Double Membrane Roofs, maximizing the conversion of organic waste into biogas and biosolid fertilizers, embodying the circular economy.
