Corrosion Resistant SMC Manhole Cover with Double-Seal Groove System and IoT Sensors for Smart City Projects

Elite’s Watertight Composite Manhole Cover System represents a breakthrough in urban drainage and water management. Designed with precision sealing technology, it prevents rainwater or surface runoff from infiltrating underground networks, effectively protecting electrical, telecommunication, and sewer systems from flooding or contamination. The cover integrates a double-seal groove system with high-elasticity rubber gaskets that ensure a perfect seal, even after years of repeated opening and closing.

Unlike conventional metal or concrete covers that allow seepage through microcracks or rusted joints, the composite SMC material used by Elite offers zero permeability and long-term dimensional stability. The watertight design ensures that underground facilities remain dry and secure, extending the service life of cables, sensors, and pipelines. This makes it an ideal solution for smart cities, data centers, and water management projects, where precision and reliability are critical.

Each watertight cover is tested under hydrostatic pressure to verify sealing performance under real-world conditions. The intelligent drainage feature—micro-engineered edge channels—allows controlled water flow, ensuring that excess water drains away quickly while preventing backflow.

Manufactured using advanced hot-press molding, the product maintains uniform thickness and surface quality, ensuring consistent performance across all weather conditions. With its corrosion resistance, UV stability, and load-bearing compliance up to EN124 D400, the Elite watertight manhole cover is a technically advanced, maintenance-free solution for modern infrastructure.

From urban stormwater systems to coastal installations and flood-prone regions, this manhole cover guarantees the perfect balance of protection, performance, and sustainability.

Key Features & Advantages:

As cities evolve toward digital and sustainable infrastructure, Elite’s SMC Composite Manhole Cover plays a pivotal role in supporting smart city development. Combining advanced material science with intelligent design, our covers are not just passive access points—they are integral components of data-driven urban ecosystems.

Through optional integration of IoT sensors, Elite’s manhole covers can monitor temperature, humidity, water levels, and unauthorized access in real time. This smart functionality allows city management systems to collect data automatically, reducing manual inspections and improving response time during emergencies.

Structurally, the manhole cover is engineered for long-term stability and durability. The SMC composite construction provides superior corrosion resistance, non-conductivity, and lightweight performance—eliminating the challenges associated with cast iron theft, rust, or breakage. Each product is manufactured to EN124 international standards and undergoes multi-step quality verification, including mechanical, impact, and fatigue tests.

Aesthetic flexibility is another key advantage. City planners can select custom surface textures, colors, and logos to match urban design themes, while the anti-slip coating ensures pedestrian safety in public areas.

From telecommunication networks and water utilities to smart drainage and electric grid systems, Elite’s manhole covers enable a seamless blend of functionality and innovation. By incorporating sustainability and intelligence into every design, Elite provides infrastructure components that are future-ready, eco-friendly, and operationally efficient—essential for the cities of tomorrow.
