Faced with a poor record of community management of rural water supply infrastructure in sub- Saharan Africa, motivating water users to make sustained contributions toward infrastructure management remains a challenge. This paper examines the incentive mechanism of water users’ tariff payment behavior by relying on a theoretical framework of common pool resources (CPRs). Using five motivating factors that were examined in the author’s previous work as mediators linking contextual variables and resource management outcomes; a) preference in the choice of water; b) satisfaction from consuming water; c) trust among peer resource users, d) perceived sanctions for non-payment, and e) perceived cooperative benefits from participating in infrastructure management, the present paper attempts to verify, through case study method, whether these are useful in understanding the real-world cases in rural African settings. Two Senegalese villages were studied over different periods of management by relying on an institutional framework of analysis focusing on changes in motivating factors and resource management outcomes. The analysis demonstrates that preference to use the water, satisfaction with the water provided and trust among peer users are related to presence and absence of users’ tariff payment behavior in the two villages; therefore confirming the validity of the conclusion presented in the previous work. The analysis also reveals that sanctioning and collective benefits can function as motivating factors under certain circumstances.
