Abstract
Waste collection and transportation is one of the crucial functional elements of municipal
solid waste management. Available information about this matter is therefore essential for
successful municipal solid waste management. The main objective of this study is to assess the
solid waste collection practice in Addis Ababa.
For the purpose of the study, 250 pre collector groups were selected for field survey of the
primary solid waste collection. Background information was gathered using semi structured
interviews with the pre collector groups and the respective cleansing management agency
officers. To examine the secondary solid waste collection, field observation on the trucks and
interviews with truck drivers and with waste agency officers of the city was carried out.
From the study, the productivity of primary and secondary waste collection was determined;
the collection capacity of the city was estimated and factors influencing the system were
identified. For primary collection, three different collection methods were identified: push cart
method, pushcart–collector method and truck collection method with average productivity of
2.12 m

/hr respectively. For secondary
waste collection, the trucks productivity were determined to be 6.29 m
/ worker/day and 2.81m

and 39.7 m

).
The solid waste collection capacity was determined to be 3,192,868.8 m
/year for the primary
collection and 2,579,183.22 m
3
/year for the secondary collection. The solid waste generation
rate of the city is determined to be 4, 157469.12m3/year. This shows that, on average, only
76% of the waste generated in the city was collected by primary collectors, and 80% was
collected by the secondary collectors. The result indicates that the current collection system
doesn’t cope with the solid waste generation rate of the city.

The role of solid waste transfer station in solid waste management is great. This study includes
the basis of design and conceptual layout for a new facility of a pilot service area. This design
and operational plan details the features and operational procedures for a municipal solid
waste transfer station to ensure a safe, operationally efficient facility that meets the waste
needs of the given service area.
