Regardless the time of day, the sewage and drainage team visits different districts of the city to check and clear sewers, ensuring the smooth operation of the system.

Especially before and after the rainy season, the sewage and drainage team focuses its work on flood-prone areas, clearing and dredging the relevant sewage systems as quickly as possible, and making every effort to ease eventual flooding in low-lying areas.

The Municipal Affairs Bureau keeps adopting new technological resources to aid in drainage-related work, including increasing the use of closed-circuit television monitoring systems to check sewer conditions, and using robots to assist in cleaning sewers and similar systems. The use of technology not only improves the efficiency of managing and controlling the city’s sewage network, but also helps to reduce the workload for frontline staff.

The Municipal Affairs Bureau’s team often needs to work underground to ensure the efficient operation of the city’s sewage and drainage network.

The Municipal Affairs Bureau’s team has to manually remove any garbage found in the city’s sewage and drainage network. The more garbage they find, the harder the task becomes.

The Municipal Affairs Bureau’s team is pictured removing buckets of silt from the underground sewage network, clearing the system in order to prevent, and ease the impacts of, any eventual flooding in Macao.

Thanks to the work carried out by these ‘guards’ of the city’s sewage and drainage network, the impact of flooding in Macao has been reduced significantly in recent years. The public should contribute to the efficient operation of the city’s sewage and drainage network by avoiding dumping garbage and oil pollutants into the system.
