SWM PRACTICES
COLLECTION OF SOLID WASTEThe Municipality Spends large proportion of its budget on collection, transport, and disposal of solid waste
Solid waste collection services divided in to two sub-systems : primary and secondary collectionPrimary collection is done by micro and small enterprisesPayment is Volume based rate( 30 birr Per m3)
![Page 12: overview of addis ababa city solid waste management system](https://reader034.vdocuments.site/reader034/viewer/2022050914/586a310d1a28ab5e1d8be839/html5/thumbnails/12.jpg)
Contd,Residents are divided in to ZonesOne Zone Constitutes 800-1000 residentsIn each zone one MSE is assigned to workThe city is divided in to 549 zones each zone comprising 800-1000households
The number of enterprises organized to work on solid waste collection is 520 with a total number of 5815 operators
Most residents are willing to cooperate with the government in financing SWM
![Page 13: overview of addis ababa city solid waste management system](https://reader034.vdocuments.site/reader034/viewer/2022050914/586a310d1a28ab5e1d8be839/html5/thumbnails/13.jpg)
Contd,Service Charges are collected with water consumption rate
Services charges are fixed according the amount of water consumed in terms of the ability and willingness to pay
Residential houses 20%, Commercial houses 42.5% of the total water consumed
Collection is regular and full coverage
The municipality has placed several garbage containers

Separation, Reuse and recycling
Sorting of waste takes place at various levels in the waste management processThe first level of source separation is at household: plastic materials, glass, bottles, are considered as valuable and usually sorted out for reuseSeveral collectors represent the second stage: Street boys, private sector enterprises, scavengers at municipal landfill, and the koralesRecyclable materials include: metal, wood, tyres, electricity products, old shoes and plastic.
![Page 15: overview of addis ababa city solid waste management system](https://reader034.vdocuments.site/reader034/viewer/2022050914/586a310d1a28ab5e1d8be839/html5/thumbnails/15.jpg)
Contd.
The municipality role in recycling is absent and mainly focus on collection, storage, transportation and disposal of solid waste.
Most of the collection of recyclable wastes in the city is performed by the informal sector
Recyclable materials are used by local plastic, shoe, and metal factories

Transport and disposal
Municipality transports from garbage containers (Secondary collection) to the final dumping site
The highest level in the transportation system is represented by municipality
The role of private sector on transportation of solid waste is highly limited

DISPOSAL OF SOLID WASTE
There is currently one open dumpsite where all collected waste
is disposed off.
It has been established 47 years ago.
The site is known as "Rappi" or "Koshe" which is South West
part of the city
Located 13 km away from the city center.
It has a surface area of 25 hectares.
The present method of disposal is crude open dumping:
hauling the wastes by truck, spreading and leveling by bulldozer
and compacting by compactor or bulldozer.
![Page 22: overview of addis ababa city solid waste management system](https://reader034.vdocuments.site/reader034/viewer/2022050914/586a310d1a28ab5e1d8be839/html5/thumbnails/22.jpg)
DISPOSAL OF SOLID WASTE
The major problems associated with the disposal site are:The site is getting full
Surrounded by housing areas and institutions
Nuisance and health hazard for people living nearby
More than 200 - 300 waste pickers per day, work continuously and obviously living nearby the site and interfering the operation of the work for collection of salvageable materials such as wood, scrap metals and discarded food.
No daily cover with soil
No leachate containment or treatment
No rainwater drain-off
No odor or vector control
No fence
No weigh bridge, inaccurate weighing of waste

BEST PRACTICES ON SWM
Decentralization of SWM Services to the lower tier of Administration
Creating employment opportunities for Micro and small enterprises ( Generates income for the poor)
Primary collection from each household is done by Micro and small enterprises
Efficient and equitable service charge collection system established( With water Consumption rate)
