Rapid urbanization, population explosion besides economic growth leading to more consumption has resulted into increased generation of solid waste exceeding existing waste management infrastructure. As a result, a substantial percent of this waste is never collected, implying it is dumped openly and this has health and environmental ramifications especially in urban areas such as Machakos town constituency in Kenya. Proximity to Kenya’s capital city (Nairobi) and located next to international road network, Machakos town constituency attracts many workers and business people as residents who contribute to massive waste generation exceeding available waste arrangements. Consequently, waste is dumped all over despite newly installed collection bins. To that end, this study sought to evaluate the effectiveness of newly installed waste collections bins in managing solid waste in Machakos town constituency. To achieve this, the present study set out to determine household perception on usage of bins, the extent to which the residents use the newly installed bins, to determine influence of proximity and placement of bins on residential use and to analyze residents’ satisfaction with frequency of town pick-ups of bins for waste disposal. The research was anchored on systems, planned behavior, waste management and institutional theories. Descriptive research design that incorporates a quantitative approach was adopted to collect and analyze data. Targeted population included households, SWM staff, county’s executive members, civil organizations, sub-county administrators, MCA and local leaders. Closed ended questionnaires were administered to 214 participants who had been sampled through Krejcie and Morgan (1970) table for determining sample size, purposive sampling and census technique. Descriptive and inferential statistics were used to analyze data. Findings were expressed in frequencies, percentages, standard deviation and means and presented in tables and figures. Findings reported low awareness and knowledge, risk of waste, uncollected waste, charged fee influenced perception of bins. Also, households took garbage to bins once a week. Bins were also not positioned in the shortest distance and only stationary bins were installed, bins were too fewer although bins were placed along roads. Additionally, bins were poorly designed with no covers and not fragmented, were unguarded, misused and vandalized. Besides, waste was collected once a week, and occasionally, no emergency pick-up. Overall, a positive and significant correlation between effectiveness of newly installed bins and SWM existed. This study recommends public sensitization campaigns on importance of save waste collection and better waste management to influence positive perception of use of bins. There is need to institute a specific waste collection time based on waste generated. The study recommended that more bins proportionate to waste generated be procured and be evenly distributed. Further, bins be positioned close to households and be placed in sloping gradient towards collection points for convenient dropping of waste. Besides, haul type of bin be introduced in addition to stationary type of bins which should be installed along roads accessible by pick-up trucks. Better designed bins with covers and fragmentation to allow waste separation as well as instituting guarding of bins, are recommended. Finally, frequency of pick-ups of waste should be increased.
