  • First and foremost, well manhole covers must be kept in reliable condition to ensure public safety. Manhole covers provide access points to underground infrastructures such as sewer systems, stormwater drains, and utility tunnels. If these covers are damaged or improperly secured, they can pose serious hazards to pedestrians and vehicles alike. A loose or missing manhole cover can lead to accidents, injuries, or even fatalities. Regular monitoring ensures that these access points remain secure and in good condition, making our urban landscapes safer for everyone.
