This study evaluates the efficiency Kampala Capital City Authority in municipal shared solid waste management in Uganda by using a framework of cost, quality and social welfare (CQS). However, this specific research only evaluates the efficiency component of divisions' performance and the two remaining units are out of scope of this research. Major basis used to gather facts was a survey. Three types of survey forms were used on three diverse selected target groups i.e., (i) residents; (ii) employees; (iii) divisions of KCCA were raised to gather relevant information. Outcomes revealed that in KCCA the rank in respect to efficiency, usage of capital is adequate and the objective is accomplished persuasively in an economic manner. Possibly, the outcomes will apply as suggestions for residents, KCCA divisions, strategy architects, planners, administrators while laying strategies and agendas in overhauling real competence of public service departments.
