THE Shenzhen Water Group recently invented an intelligent manhole cover that sends data about water levels and alerts if the cover isn’t installed properly, the Southern Metropolis Daily reported Saturday.

The covers are expected to be installed in January and introduced citywide after the Spring Festival.

Several incidents of pedestrians falling into sewers during floods in China put the problem in the public spotlight. Manholes that are inappropriately covered are extremely dangerous for passers-by.

Flooding during the rainy season is also an urgent problem that needs to be solved in many cities.

A device is attached under the cover to monitor the water level and whether the cover is properly installed. A text message will be sent to supervisors if the water level is unsafe or the manhole cover is not safely installed.

The water-level detection system will send data back to the supervising center and maintenance staff will be dispatched to fix problems.

​The designers of the cover think the device can help the city deal with flooding during extreme weather.
