Residents of Dandora will have to put up with the dumpsite for 10 more years as engineers start compacting the waste to create extra space.
This comes even as garbage pile-up in Nairobi remains an eyesore and a health hazard.
Nairobi County Hall has now turned focus to find a short term solution to solid waste management.
Speaking in his office, County Secretary Robert Ayisi said City Hall had accessed the dumpsite and realized the waste had only been deposited at the entrance of the site and there is space for more garbage for the next ten years.
Dr Ayisi, who defended the environment department which has been accused of failing to keep the city clean, said the county had improved in garbage collection compared to December 2015.
