Project General Description

The Zanzibar Urban Water and Sanitation Project is a project based operation investment of UA 15.6 million, over a time frame of 4 years, from 2013 to 2016, to rehabilitate and upgrade the water production, transmission and distribution systems and to provide sanitation and hygiene facilities in schools in the Unguja urban area. At present, about one third of the Unguja installed water production capacity of 50,000 cum/day is operational, because some of the facilities require major rehabilitation or replacement. In addition, a significant proportion of the water produced does not reach the consumer tap, as it is lost on the way, through leakage, largely due to the poor operational condition of the distribution system, installed in the 1960s. Consequently, water services delivery in the Unguja urban area is discontinuous and unreliable and most customers get water only twice per week. Improved access to water supply will also sustain other services and socio economic activities, including tourism, which makes a significant contribution to the economy of Zanzibar.

Project Objectives

The sector goal is to contribute to socio-economic development, poverty reduction and improvement in the standards of living and social well-being of the population by ensuring equitable and sustainable provision of reliable water and sanitation services. The project objective is to improve water supply and sanitation infrastructure and services in Unguja Municipality, which is Zanzibar’s administrative centre and the hub of its economic, cultural and tourist activities.


The project will benefit the population in the urban area of Zanzibar. The proposed intervention will enhance public health and raise the living standards of the Unguja urban population, comprising about 500,000 people, equivalent to 40% of the total population of Zanzibar. Students and teachers in schools will benefit from improved sanitation facilities, while communities will benefit from sanitation and hygiene training and promotion. Vulnerable groups in the project area will also benefit from the project.
