Abstract
The present study entitled assessment of solid waste management in Damboya town Damboya’s
distirict kambataxambarozone southern Ethiopia conducted withmain objectivesof assessing the
solid waste management ways of effects of solid waste and identifying common solid waste
disposed in the study area smile random sampling method was used to collect data from selected
40 households out of 906 total households and semi-structured questionnaires distributed to get
all necessary information for the study majority of solid wastes disposed in the study are were
rubbish (24.19%) of total wastes disposed and garbage (17.74%) the most predominate methods
of solid waste management applied in the study area are incineration (29.5%) and open burning
in the yard (18.03%) there was a problem related with solid waste accumulation in the study area
majority of people ( 45%) are affected by food and water born disease to solve this and other
related problems educating people on the efficient solid waste management is the most important

1. Introduction
1.1. Back ground and justification
Solid waste can be defined as non-liquid and non-gaseous products of human
activities that regarded as being useless and could take from of refuse garbage and
sludge waste disposalis one of environmental problem that has been great concern
to local in habitants, local state and federal government as well as the world in
general (leten, 2004)
Good management waste collection and its disposalis a fundamental need for every
city to provide clear and healthy environment for citizens. The current low level of
environmental safe in general and sanitation in particularly both rural and urban
areas in the country emendates from the lack of clear national policy on sanitation
and environmental hygiene. (MOH, 1987)
Improper waste management may have health, environmental and economic
problems. Ecological phenomena such as water, air and soil pollution have been
attributed to improper management of solid waste. Thus, public health service has
published the result of the study tracing the relationship of different diseases to
improper solid waste management. The waste water is the cause of the enteric
communicable diseases. Human excrete contains disease causing organisms. Thus,
it is the sourceof many infections (George and Samuel, 1993)
Sanitation is fundamental to human development security, the combined effect of
inadequate sanitation, unsafe water supply and poor personal hygiene, unsafe
water supply and poorpersonal hygiene are responsible for causing disease such
as Entaomoeba histolytica, Gardialambia and several water born and food born
disease. Thus, sanitation, problem is the source for several communicable disease

2
(WHO, 1984). In many cities ofEthiopia, water management is poorand sold wastes
are dumped along road, water bodies and in to open areas endangering health and
affricating vermin(Tewodros et,al, 2008)
In Damboya and many towns of Ethiopia, there was many sanitation problems, of
which solid wastes contribute the highest amount.
Most households in Damboya town accumulate solid waste in many available open
areas.
The socio-economic character of community, individual behaviors and public
practice which are responsible in efficient solid waste service, but also public
acceptance and participation. The place may also engaged a program aimed at
improving the behavior and practice of the people in this respect (Faris, 1993)
1.2 Statement of the problem
According to world health organization expert committee the scattered solid wastes
in market areas, road sides or offices create soil, water and air pollution. This emits
a bad smell to the environment and it is also creates a suitable condition for breeding
offlies and rodents which are vectors formany disease in many developing countries
in the world.
In Damboya town, there were many sanitation problems from these , solid wastes
contributes to the highest amount most house holders in this town accumulates
solid wastes in many available open areas, these wastes products are habitat or
suitable environment for breeding of many vectors. This resulted in public health
problems, more over there was no previous research on solid waste disposaland
management ways in the study area, therefore, the present study reveals proper

3
management of solid waste disposal and suggests possible ways reducing the
problem associated with of solid waste and management
1.3 The researchquestions

combustible )
 Garbage(decomposablewastes from food )
 Ashes(residues of combustion of wood or fuels)
 Remains of dead animals.
 Agricultural wastes (from animal manure and crop residues)
 Industrial wastes (chemicals, paints and sands)
2. Which methods of solid wastes management are mostly applied?
Open burning in the yard
Incineration
Sanitary land fill

Composting
3. Could you list the problems related with solid wastes
4. Explain solid wastes management
5. What problems are related with improper solid wastes management?
o Air pollution
o Water pollution
o Increase vectors

4
6. What challenges are there in your locality for poor solid wastes disposaland
management?

development and beatification of the town there by avoiding solid wastes
accumulation. It also helps as a source of reference and intiation the studies
professional for the direct intervention of the problem.
The study may also give a clue for further investigation on related problem in
the study area .The studywould develop a sort of integrites to manage the effects
of the solid waste management in Damboya town kamabata tambaro zone SNNPR
Ethiopia.
Generally, it gaves first hand information for Damboya town health center and
governmental and non governmental organizations in managing solid wastes.
1.6. Delimitation of the study
During the study the following problems were limiting factors. Since the research of
the study is in service trainee. He faced shortage of time to find reference books,
documents and reading materials which supportthe study.

6
The mostoutstanding limitation of the study are: financial limitation and electronic
materials.
1.7 Delimitation
This study was restrictly conducted on Damboya town on problems associated with
Assessment of solid waste management.

2. Literature review
2.1 waste disposal
Solid matter is created by human or animal activities and which are disposed
because they are hazardous or useless are known as solid wastes. Disposal of
wastes is the problem of the world. This problem. Continues to with growth of
human population and development of industries (Leton, 2004)
2.2 types of solid wastes
Solid wastes typically many be classified as garbage (decomposable waste from
food), rubbish (non decomposable waste either combustible waste such as metal,
glass ceramics), ashe (residues of combustion of wood or fuels), large wastes
(demolitation and construction debris and trees ), swages(treatment solid materials
retain on swage treatment, screens, settled solid and biomass sludges), industrial
wastes (materials such as heaps and coal refuse piles ) and agricultural wastes
(farm animal manures and crop residues ) (Achankeng and Eric, 2003)
2.3 managementof solid wastes
Traditionally, waste management strategies includes reusing materials recovering
materials through recalling , incarnation and land fills, in recent years recycling
becomes the proffered choices of wastes disposal for many industries on the
commercial levels, government, regulation works to the advantage of big firms
and to the disadvantage small one (WMO, 1987)
2.4 effects of improper solid waste management
The healthy hazards posed by vermin, unsupervised scanvenging and the open
burning of waste leading to toxic release to both ground water and air. This
contributes to lasting damage of the environment and have a serious implication for
the healthy of local people and like stocks (Tgeths, 1995)

8
Garbage collection service area in adequate in most residential areas ofdeveloping
countries of citizens and estimated 30-50% of solid wastes generated health
problems, the poorer house holds suffering more since it is poorer areas of the
sites that have services to collect garbage or service are very inadequate (salvato,
1992)
3. Methodology
3.1 description of the study area
This study will be conducted in Damboya town. The administrative town of
Damboya woreda which was located in SNNPR state about 182km away from west

5, DISCUSSION
MAJORITY (30%) and (20%) of respondents responded that rubbish and garbage are the most
predominant solid wastes in the Damboya town respectively. Rubbish accounts (24.19%) of total
solid wastes and garbage was (17.74%) of total soil wastes. In the study area. This findings was in
agreement with previous research of Leton,(2004) who reported that about (80%) of total wastes
are rubbish in study conducted at Nigeria, Abuja.
Majority (27.50%) and (20%) of respondents in the study area practice incineration and open
brining in the yard respectively as a method of choice for managing solid wastes in the Damboya
town. WHO, (1987) similarly reported incineration probably accounts for more than (90%) of solid
wastes management in many countries of the world.
The health hazards posed by vermin and the open burning of wastes leads to toxic release for both
ground water and air. The present study findings shows that majority (45%) of respondents in the
study area were suffering from food and water born disease like amoeba, guardian, typhoid and
cholera, similar research conducted by salvato, (1992) shows, that(30-50%) of peoples per year
are affected by food and water born disease in new York. Therefore, this should be reduced by
using hygiene education which largely related to hand washing in particular and applying proper
waste disposal way in general in Damboya town.

6 Conclusion and Recommendations
Conclusions
In Damboya town soil wastes are dumped along road sides and open areas. The
most (24,19%) of disposed wastes was rubbish and majority (30%) of
respondents responded that this types of waste was the most common in the study
area. To reduce accumulation of this wastes solid waste disposal and
management ways are applied in the study area. Among these managem ent
methods, (29%) of wastes are managed by incineration and majority of
(27,50%) respondents use this method. Open dumping of wastes along road sides
and open areas lead to toxic releases to both ground water and air. These
contribute to lasting damage of the environment and have serious impacts for the
health of local people and live stocks. As the study findings shows that (45%)
of the respondents are suffering from water borne diseases such as amoeba,
giardia, thphoid and (20%) of respondents were affected by common cold due
to contamination of air . Therefore, this should be reduced by using hygiene
education and applying propel waste disposal methods in the study area.
6.1 Recommendations
Based on the findings of the study, the following recommendations were drawn.
1. Solid waste disposal mechanism should be modernized

17
2. Educating the people on the efficient solid waste management.
3. Engagement of a program aimed at improving the behavior and practice
of the people in this respect.
4. Well municipal solid waste disposal service should be establishes
provide proper solid waste management.
5. Leaders shall adapt and reinforce rules, regulations and guidelines that
govern solid waste management of the town.
6. Public acceptance and participation of society
