Water Resources Management, Zanzibar

Zanzibar is a semi-autonomous part of Tanzania, in East Africa.The Zanzibar Archipelago is composed of two large islands, Unguja and Pemba, and numerous small islands off the coast of the mainland. The capital of Zanzibar, located on the island of Unguja, is Zanzibar City. 


IWRMS: The Intergrated Water Resources Management System (IWRMS) includes a central GeODin database with tools & modules for data management, data analysis, presentation and modelling. Various data and information types are used, including hydrogeological data,  borehole data, geological data, monitoring data, water levels, pumping tests, flow data, rating curves, meteorological data, water quality parameters, water use data, water users and stakeholders, water rights and licenses, discharge permits, demographic data, agricultural production and pollution data.


Implementation: This was carried out in close consultation with the Zanzibar Water Authority (ZAWA). Fugro provided a special tailor-made solution for ZAWA that allowed them to select and combine GeODin software features required to meet their specific data management needs. For example the local wards (Shehia) were intergrated in all data collection masks. 


Knowledge transfer: Consultation and training were carried out as part of the knowledge transfer process from Fugro hydrogeologists and software specialists to the local ZAWA staff and consultants. Emphasis was placed throughout the project on enabling local staff to become competent users of the IWRMS and achieve an independence of external consultants. A GeODin guide was specially prepared to act as an IWRMS manual, augmenting the very comprehensive integrated English help system. 

The IWRMS interfaces and experience in working with data in a hydrogeological context are just as important as the programs themselves. Hence it was of paramount importance to define the project goals at the outset, so that the data collected could be organised in an appropriate structure. This hand-in-hand approach of software programming,
