Abstract

Sewage discharges from centralized water-borne collection systems can pollute surface water, and discharge from sewers; septic tanks and pit toilets pollute living environment and groundwater which directly affects the health of poor people at downstream [13]. Poor sanitation facilities and low sewerage system continues to be a critical problem in rural and urban areas of Ethiopia. This study aims to evaluate the sewerage system in terms of technical aspect by identifying the cause and extent of failures on the schemes then forwarding the mitigation measures for the problem explored. This study is conducted in Debre Berhan town from February, 2014-January, 2015. In order to gather information’s for the study, the researchers used pre-prepared questionnaire (for the condominium lives), soil sampling and the other was data collection checklists (variable and context information checklists), semi open ended interview and physical instruments such as GPS, Axes soil sample bags. From the study, some important conclusions are made. The technical performance evaluation indicators show that sewerage system especially around condominium area is poorly implemented, inadequate in quantity, or poorly constructed or both. Of the total users around 31.54% have no any awareness about sewerage system operation, sanitation and hygiene. Of constructed floor drainage ditches only 24.8% have good appearance and functional, in the rest of scheme, the structure is destructed and non-functional. Only 36.47% of septic tanks, gives good function for users properly as required, in the rest of the schemes, there is many defects and problems observed. The technical problems noticed in the sample sites are includes O&M, construction, and design respectively put in the order of causing considerable failure.

Highlights

Sanitation facilities with safe sewage disposal methods reduce the numerous diseases but are very often the first step towards to other development activities (MDGs).Poor sanitation facilities and low sewerage system continues to be a critical problem in rural and urban areas of Ethiopia
In addition to constructing new sanitary schemes, attention should be given to operation and maintenance of the existing schemes, in order to achieve the envisaged objectives
Debre berhan is one of fast growing towns found in Ethiopia located in north shewa zone, Amhara regional state, about 130kms north east of Addis Ababa on paved highway to Desse [10]

Summary

Introduction

Sanitation facilities with safe sewage disposal methods reduce the numerous diseases but are very often the first step towards to other development activities (MDGs). Poor sanitation facilities and low sewerage system continues to be a critical problem in rural and urban areas of Ethiopia. Substantial achievements will not be achieved unless the factors contributing to poor implementation of the old schemes are fully explored. Previous experiences should be taken into account in the new schemes to avoid repetition of problems. Evaluation of impact is a longer-term activity. It is the process by which results of development projects are measured against their targets or objectives to see whether they have had the intended impacts or any undesired negative effects [20]
