Until recently there has been little, if any,\nconcern over revamping let alone improving wastewater\nmanagement system in Zimbabwe�s urban areas given the\ndominance and institutionalised water-borne system. Yet,\nthe current constraints in this system and the immensity of\nurbanisation in the country begs and compels planners,\nengineers and systems thinkers to rethink what best can\nwork as a sustainable wastewater system. With particular\nreference to the ever-expanding Harare metropolitan\nregion, this article provides an evaluative analysis on the\npotentiality, risks and strategies that can be adopted by\nHarare and its satellites in addressing the problems of the\nconventional wastewater management system. The suggested\nframework of operation is a decentralised domestic\nwastewater collection and treatment system which however\nhas its own multifarious risks. Using systems dynamics\nconceptualisation of the potentiality, opportunities, risks\nand strategies, the paper seeks to model the path and outcomes\nof this decentralised domestic wastewater collection\nand treatment system and also suggests a number of policy\nmeasures and strategies that the city of Harare and its\nsatellites can adopt.
