Public private partnerships for successful solid waste management and prospects for reducing public health risks in Kinondoni Municipality-Dar es Salaam, Tanzania

Abstract

In Tanzania only 40% of solid wastes in urbanized areas are collected and transported to the dumping sites. Theremaining 60% are illegally disposed along road sides, sewage canals and reserved open spaces that contribute tofloods and breeding of rodent vectors that eventually spread diseases such as intestinal schistosomiasis and soiltransmitted helminths. Public Private Partnership (PPP) has been adopted to address Solid Waste Management(SWM) in various countries and yielded robust results. However the PPP model has not been effective for Tanzaniasince its initiation in 1995. Therefore this paper examined factors influencing performance of PPPs in SWM atKinondoni municipality. A cross sectional survey was employed to collect data that was analyzed using descriptiveand multiple regression model. Findings showed that poor monitoring and evaluation practices influenced poorperformance of PPP in SWM. Moreover, low capacity of the contracted companies, limited accessibility of residentialareas and weak enforcement of laws and regulations governing solid waste management had negative influence at0.05 significant levels. The study recommends the system should establish regular plan in combination withimprompt monitoring to eliminate the effect of possible falsified compliance. Furthermore, the municipal council hasto improve town settlements to access the households easily for SWM. Lastly research on end use products of thewaste should look at the technical, economic viability of the waste markets for the products processed from the wastefor mitigating public health risks associated with SWM.
