Addis Ababa Water and Sewerage Authority (AA WSA) was established to provide potable water for the residents of Addis Ababa and to discharge waste water from the city. The Authority uses different facilities for providing its services. The water distribution and sewer network systems are among the facilities which cover large geographical area, and need day-today maintenance and operation. AA WSA needs and uses different types of mapped and recorded sources of information for managing the water distribution and sewer network systems. In relation to the management of the water distribution and sewer network systems, a survey has been conducted to assess the information needs of the users, and the support of the existing information services. The major problems in getting adequate information have been identified. The methods employed for the purpose of data collection include questionnaire method, interview method, observational study, and literature survey. The results of the study generally indicated that the users need various initially generated mapped and recorded information for different managerial, operational, and planning purposes. The survey indicated also that the users had problems in getting timely access to reliable and adequate information, and the existing information services were deficient in meeting their requirements. To improve the services of existing information systems and to create conducive condition for the users to get timely, relevant and reliable information, the study has proposed the development of two separate but closely linked systems: the library system; and the computer based information support system. For the computer-based information support system, the required application systems have been identified . The detailed logical design of the application systems, and the detailed logical and physical database designs have been carried out. The prototype databases and a user interface have been designed to demonstrate that the applications are implementable and user-friendly. Specific recommendations for the improvement of the information services of the MWSA Library, and for the implementation of the computer-based information support system have been made.
