He said the clean-up will be done on every first Saturday of the month.
While launching the exercise, Sonko urged residents to turn up in large numbers in their various wards whenever the exercise is carried out.
“This is our city, lets all work together to make it clean,” he pleaded Saturday when he launched the exercise in Kayole.
Among the areas he supervised the clean-up include Westlands, City Cabanus, Dagoreti South among others.
The county government provided equipment such as brooms, wheelbarrows, and spades and refreshments to encourage Nairobi residents to take part in the exercise.
But there are those unhappy with the exercise because they pay taxes.
“Why should we participate in the clean-up exercise yet we pay taxes,” one city resident posed, “We pay taxes to enable the county government provide us with services, I don’t think that is a good move at all and that is why I will never participate.”
But for others like Mercy Mwangi, “This is a good initiative because it will ensure the city becomes clean. It should be done even twice a month.”
The clean-up and beautification exercise was carried out in all the 85 wards.
Still as part of measures to combat garbage menace, the Governor said they have provided in the budget an allocation to build a central garbage collection points in all the wards, where residents can leave their garbage after collection.
Sonko said that they are in final stages of awarding a contract of constructing the Dandora waste recycling plant which will be recycling garbage and produce electricity.
The plan to set up the multibillion plant was revived after the county government finally acquired a title for the land.
The concept is borrowed from Rwanda’s capital Kigali, which is arguably the cleanest city in the region.
