The study examined the impact of Mukwano Detergents Company on infrastructural development in Kampala, Uganda. Mukwano Group of Companies, established in 1986, emerged as one of East Africa's leading manufacturing conglomerates with significant operations in household consumer goods production. The company's expansion and operational scale necessitated substantial infrastructural investments, both within its facilities and in surrounding communities. The research investigated how a major private sector manufacturing entity contributed to infrastructure development through direct investments, partnership initiatives, and indirect economic multiplier effects. The study was premised on the understanding that large-scale manufacturing companies often served as catalysts for infrastructure development in developing economies, particularly in areas where public sector investment remained limited. The study employed a case study research design utilizing both qualitative and quantitative approaches. Data was collected from 120 respondents including Mukwano Group management (15), employees (50), local community members (40), and government officials (15) through structured questionnaires and semi-structured interviews. Secondary data was obtained from company reports, government infrastructure records, and academic publications covering the period 2010-2023. Purposive and simple random sampling techniques were utilized to select respondents. Data analysis was conducted using descriptive statistics and thematic content analysis. Infrastructure development was measured across four dimensions: physical infrastructure (roads, utilities), social infrastructure (healthcare, education facilities), economic infrastructure (supplier networks, distribution systems), and technological infrastructure (communication systems). Results indicated that Mukwano Detergents Company made substantial contributions to infrastructural development. The company invested approximately UGX 12.5 billion in direct infrastructure improvements between 2010-2023, including road construction (4.2km of access roads), water supply systems serving 15,000 residents, and electricity grid extensions reaching 8 neighboring communities. Employment generation stood at 2,450 direct jobs and an estimated 8,700 indirect jobs in the supply chain and distribution networks. The company established 23 health and safety facilities, supported 12 educational institutions, and facilitated technological infrastructure through digital payment systems reaching 450 retail partners. Statistical analysis revealed strong positive correlations (r=0.78, p
