|dc.description.abstract||The aim of this research was to investigate the factors affecting performance of the Makerere University sewerage system which could lay a ground for future development of its infrastructure and also be used to solve all grand factors affecting the system. The scope was limited to Nsibirwa hall of residence.
Maintenance of sewer lines is key in management of sewer lines of different types classified according to material as asbestos cement, brick, cement concrete, cast iron, steel, plastic and according to design as sanitary and combined sewers.
Nsibirwa hall has a total of 33 toilets, 33 bathrooms, 33 sinks and 15 urinals to service 435 residents and guests (non- residents). The sewerage system at the hall was constructed in 1952 to cater for a student population of 216 students.
Consultations were mainly done with Mr.Katabira Ssenyonga Douglas the Nsibirwa Hall Custodian, Mr.Bbossa Francis the Nsibirwa hall Chief Custodian, Mr. Ganafwa Geter, the Head of Mechanical and Civil works, plumbing and sewerage management in the University, Mazinga Mark the hall chairman, Sserukuma Godwin the hall interior minister and a sample of 48 students whose names, year and courses are listed in the appendix. Questionnaires and predetermined questions were used in this process.
Different factors including inability of system to cater for existing population, poor system usage, inadequate funds for maintenance and repair, inadequate staff to maintain and repair the system and system infrastructure were analysed and assessed basing on both qualitative and quantitative data.
It was therefore established that Nsibirwa hall sewer performance is mainly affected by blockages due to open manholes and dumping of non-biodegradable substances in toilets. The high population also reduces the hall to a commercial building rendering its infrastructure outside the economic life Span of 30-50 years.i would therefore recommend installation of manhole covers, outsourcing labour, more funding and adjusting the pipe diameters at Nsibirwa from 100mm to 300mm which would cater for a population of over 600 students||en_US
