We fully implement "slightly moist cleaning" on the city road and shift from rough cleaning to refined cleaning, from simple repetitive work to scientific and comprehensive work. Road sweepers, sprinklers, high-pressure flushing trucks and dust suppression vehicles act together to implement a combination of mechanized cleaning and manual cleaning, improving the quality of cleaning in all aspects.

CNTY has received the franchise for providing comprehensive urban services for Hai’an city, including cleaning 13 million square meters of streets, and the collection, transportation and treatment of all the municipal solid waste. CNTY has accumulated large amounts of data through its cloud platform since the start of this project, and is thus able to manage the vehicles, personnel and facilities in a more intelligent manner and achieve standard and efficient operation.
