Description

The project components are the following: (A) Institutional Development Support - This component will cover support to ZAWA. The component will assist in updating of the Business Plan; will assist in enhancing the capacity of ZAWA in technical, commercial, and financial areas; will assist in project management activities; will assist in activities to decrease the unaccounted-for-water; will support the billing and collection systems; logistical support, equipment and training will be provided; short-term training including study tours will also be undertaken for key staff; will provide transport to assist the project management and coordination activities; studies will be undertaken to update and value the fixed assets; cost of service supply study including tariff review after two years; public health awareness/sanitation and hygiene promotion to address the issues of institutional harmonization of provision of water supply and adequate sanitation facilities targeting members of communities responsibly of handling water and sanitation issues and increase family members and communities behaviour changes toward sanitation and hygiene; and provision has been made for the annual technical and financial audits of ZAWA. (B) Rural Water Supply and Sanitation - This component covers the development and implementation of ZAWA's Rural Water Supply and Sanitation Program. This will involve determining the current levels of rural water supply and sanitation and development/implementation of a rural water supply and sanitation program, including schemes for: Dunga/Tunguu (Unguja), Kambini (Pemba), Machui (Unguja), Matemwe/Nungwi (Unguja), Mzingani (Pemba), Ndagoni (Pemba), Vitongoji (Pemba), and Wambaa (Pemba). A school water supply and sanitation action plan will be part of this component targetting adequate water supply and sanitation for all schools in rural areas by the end of the proposed project. Also health centres and market places will be targeted. (C) Urban Water Supply and Sanitation - This component will include the water supply and sanitation improvements including water testing laboratory facilities and providing leak detection equipment and the implementation of leak detection programs for Zanzibar, Chake Chake, Wete and Mkoani Towns. Zanzibar Town: The town has population of around 400,000. While additional sources have been drilled and storage capacity has been increased, nothing has been done on the very old, mainly consisting of asbestos cement, distribution network, resulting in a very high unaccounted-for-water. To satisfy the demand for 2015 and to reduce the unaccounted for water to an acceptable ratio the distribution network will be rehabilitated, replaced, and distribution network zoning implemented. Chake Chake Town: The town has an estimated (2008) 41,200 inhabitants. The water supply is currently rationed to a few days per week. The sanitation situation is not up to standard and is deteriorating. There is need for a massive public health awareness campaign to initiate a change of behaviour of the population. To satisfy the water demand for the year 2015 new boreholes have to be drilled, a 5.5 km rising main has to be laid, an elevated 500 m3 has to be constructed, 51 km distribution mains of different sizes have to be laid Wete Town: The town has an estimated (2008) 32,600 inhabitants. The water supply is currently rationed to a few days per week. The sanitation situation is not up to standard and is deteriorating. There is need for a massive public health awareness campaign to initiate a change of behaviour of the population. To satisfy the water demand for the year 2015 new boreholes have to be drilled, a 0.5 km rising main has to be laid, an elevated 500 m3 has to be constructed, 35 km distribution mains of different sizes have to be laid Mkoani Town: The town has an estimated (2008) 20,000 inhabitants. The water supply rationing is currently being practised. The sanitation situation is not up to standard and is deteriorating. There is need for a massive public health awareness campaign to initiate a change of behaviour of the population. To satisfy the water demand for the year 2015 new boreholes have to be drilled, a 0.5 km rising main has to be laid, an elevated 300 m3 has to be constructed, 14 km distribution mains of different sizes have to be laid (D) Water Resources Management - There is need for ZAWA to improve and deepen its knowledge of the available ground water resources base of the islands including what is annually abstracted. The issues to be addressed include awareness creation of water resources management, establishment of an adequate groundwater monitoring system, including adequate enforcement of abstraction and discharge regulations/permits, as well as promote water demand management, rain water harvesting and implement strong/effective water conservation practices.


Objectives

Project Objective: the project objective is to improve water supply and sanitation services in urban, peri-urban and rural communities within the service areas of the Zanzibar Water Authority.


Rationale

Zanzibar Island has severe water shortages and communities rely on an old water supply system. This system is no longer reliable and much of the water is lost through leakages from the old distribution system in place. Further, fresh water sources on the Islands are limited and some of these have been contaminated. With climate climate and an ever growing population, there is need for an intergrated approach to water supply on the Islands. Zanzibar has had no interventions from the Bank in the recent past. This followed a loan cancellation in the late eighties which arose from the then refusal by the Revolutionary Government of Zanzibar to implement a water tariff that was a condition of the investment at the time. An improved water supply in Zanzibar is expecetd to improve the health and social well being of the Zanzibari people while at the same time incerasing the economic potential that the Islands possess in the form of tourism and other related industries. The Bank has been involved in the water and sanitation sector since 1976. Currently the only other ongoing operation is the Tanzania (Mainland) Rural Water Supply and Sanitation Program (RWSSP II). This follows recent completion of the Dar es Salaam Water and Sanitation Project and the Rural Water Supply and Sanitation Program (Phase l) - both investments were completed and PCRs done in 2010. A new investment is planned for FY 2012 for Zanzibar Urban, Unguja Island. This invesment is estimated at UA 14 million and will complement the ongoing Investment which focus mainly on Unguja Island Rural and Pemba Rural and Urban Islands. Preparation for the new Investment is on course and will be carried out in March 2012 and is expected to be submitted to the Board by Q3 FY 2012, at the latest.


Benefits

The expected project outcomes are as follows: "Improved capacity of ZAWA to implement water supply, sanitation infrastructure "Improved access of people from Zanzibar to water and sanitation services "Improved capacity of ZAWA to provide and administer policy and act as a facilitator of overall water supply, sanitation and solid waste sector development and investment; and "Improved knowledge and management of the water resources of Zanzibar
