The model of public infrastructure provision in the domains of health, education and roads in the Wum Municipality is typical of Cameroonian society. It proves incommensurate with the growing knowledge endowment, technological advances and challenges in these domains. In this article, the authors examine the socio-economic challenges and impacts of the public infrastructure provision model. To achieve this objective, data were collected through direct observation, interviews and focus group discussions and complemented by documentary explorations, where related works in public institutions and online publications were consulted. A GPS Garmin model device was used to locate realised infrastructure and on-going projects. Photographs were taken using a smart phone, (Sony type) to enable the materialization of the observed phenomena. Google scholar was the principal research engine through which documents were obtained from the internet. The findings revealed a mixed scenario, precarious on one hand and promising in the other based on the indicators of progress and retrogression concomitantly observed. Using this model, results show that the provision of social facilities like schools, health centres benefited the population in terms of accessibility improvement. The same results revealed that this centralized state-led model of provision of livelihood facilities has created a societal problem – unsustainability of public infrastructure. This is noticed from the rapid degradation of recently executed projects. The phenomenon has further helped to accentuate poverty in the municipality. The paper concludes that project owners and contractors should put in place an efficient and autonomous control system to check the quality of material and technicians used in the process of public infrastructure provision.
