Project General Description

The Zanzibar Water Supply and Sanitation Project is a new phase of the AfDB's intervention in the water sector in Zanzibar after the rural water supply project completed in the early 1990s. This is an operation covering several aspects of Zanzibar's water and sanitation sector. This project was partially completed when it was stopped and the remainder of the loan cancelled due to the Zanzibar government's insistence that national water supply should remain a free public service, as it has been since 1981, in contradiction with the terms of the loan agreement. The project, jointly prepared with UN Habitat, includes support for institutional development, urban water supply and sanitation and water resources management. It will be implemented over a four-year period at a total cost of UA 33.30 million. The project will make overall improvements to public health in the project areas, reduce waterborne diseases, and promote environmental sustainability. It will contribute to poverty reduction and the achievement of the Millennium Development Goals (MDGs).

Project Objectives

The project objective is to improve water supply and sanitation services in rural and urban communities supported by integrated water resource management.


The project beneficiaries for the Rural Water Supply and Sanitation component are 95,214 (works for Dunga/Tunguu, Kambini, Machui, Matemwe, Nungwi, Mzingani, Ndagoni, Vitongoji, Wambaa), which will increase the current coverage rate from 55 per cent to 65 per cent; the school water supply and sanitation programme, with approximately 276,000 students; the urban water supply and sanitation component, with 70,832 (towns of Chake Chake, Wete and Mkoani), which will increase the coverage rate from 75 per cent to 85 per cent; water resources management: in principle the entire population will benefit from the project. Beneficiaries will have full-time access to improved water supply and sanitation facilities capable of meeting current and future demand until 2020.
