- Regulatory Compliance Urban planners and engineers must adhere to local regulations and standards when designing and installing recessed round manhole covers. This includes compliance with load ratings, environmental impact assessments, and safety standards.
Finally, the Wrekin manhole covers tell a story—about a town, its landscape, its people, and their unwavering connection to nature. They serve as a reminder of how simple objects can encapsulate a wealth of meaning, history, and beauty. As we walk over them, we partake in a shared experience, becoming part of a broader narrative that celebrates both urban infrastructure and natural beauty.
The European norm EN 124 of 1994 applies to manhole and storm drain tops with a clear opening up to 1 m for areas subjected to pedestrian or vehicular traffic (covers with a clear opening over 1 m are specified in the British Standard BS9124 for example).[30] EN 124 specifies several weight classes depending on the application and is also being used in some countries outside the European Union. The lightest class A15 (cast iron) manhole cover can withstand a maximum weight of 1.5 tonnes. It would typically be restricted to light duty applications in pedestrian areas, gardens, patios, driveways and similar. By contrast, the heaviest class F900 manhole cover can withstand a maximum weight of 90 tons, making it suitable for docks, airports, and other extreme heavy-duty applications.[31]
