Video: A Customisable In-manhole Sampling Robot for Sewage Surveillance

Unlike the traditional bulky auto-sampling device, the customisable in-manhole sampling robot is small in size and can be installed inside a manhole, thus reducing the manpower involved and the impact on traffic during sewage data collection.

After installation, the device will collect sewage samples automatically and allow customisable control for sampling activities and real-time feedback collection via Mobile App and Narrowband Internet of Things (NB-IoT).
This device has been widely used in Hong Kong and has enabled the city-wide sewage surveillance to help control the COVID-19 pandemic.

It was developed by Professor Tong Zhang and the team from Civil Engineering of HKU together with the Drainage Services Department and the Environmental Protection Department.
