Mass balancing as a tool for assessing integrated urban water management (original) (raw)

2000

Abstract

Mufakose, a high-density suburban area, located within the city of Harare in Zimbabwe, is investigated with respect to the performance of the water and wastewater systems. Integrated urban water management entails the holistic management of all water fluxes in an urban-shed and identifying the interactions between the different components.
