Participants swept roads and corridors, collected garbage, and planted trees.
Residents attribute the problem to the new building's construction blocking the sewage system, causing pressure to burst the manholes.
Hibrahim Otieno, Nairobi County's chief officer for the environment, defended the practice, explaining that wet waste from drains is left to dry before collection to facilitate easier handling.
The exercise followed a meeting on Thursday between the EBDA and Nairobi City County officials to address the garbage menace in Eastleigh.
Eastleigh residents have been protesting against the poor state of roads, poor sanitation, and uncollected garbage in the business hub.
