The Department has a workforce of about 5,900 to keep the city clean and provide cleansing services, including street sweeping, waste collection and other cleansing work in Hong Kong.
Workers normally begin working at daybreak and continue until late evening.
All streets are manually swept at least once everyday. In the main commercial and tourist areas, streets are swept an average of four times a day, and up to eight times a day in the busiest pedestrian areas. In addition to manual sweeping, there are 44 mechanical sweepers for the cleaning of highways, flyovers and central road dividers. These mechanical sweepers normally swing into action after midnight when there is less traffic. 66 street washing vehicles also operate day and night with the frequency of street washing ranging from on need basis to at least 2 times weekly depending on the nature of the area served.
