  1. The Vietnam Urban Water Supply Sector Database

Within the framework of the Vietnam Urban Water Supply Development Project, a World Bank funded project, the “Urban Water Sector Database Establishment” program was implemented from August 2001 to March 2013. Its objective is to support MoC (the national urban water supply management agency) in developing and maintaining a long-term, systematical and comprehensive data base on the performance of the urban water utilities in Vietnam: the Vietnam Urban Water Supply Sector Database.

With the efforts of Administration of Technical Infrastructure – Ministry of Construction, MABUTIP and his Consultants and Urban Water Supply Utilities (WSU) throughout the whole nation the Program has:

  1. built a data collecting tool and a set of performance indicators for an WSU, namely:

  1. a data collecting tool which is an excel spread-sheet questionnaire including 151 questions. It is attached also a Guidance Manual to support the water utilities complete the questionnaire; and

  2. a set of performance indicators for a WSU including 51 indicators, which can be calculated from the data, filled in the questionnaire by the WSU.

  1. collected the data from WSUs. The program has investigated 86 WSUs and through the questionnaire collected the input data of 81 Utilities of all 63 Provinces/ Cities over the nation. The input data in these 81 questionnaires were reviewed and then clarified and supplemented. However the data of two WSUs (the Dien Bien Construction and Water Supply Co. and the Lang Son Water Supply and Sewerage JSC.) were not used due to insufficient reliability. Thus, the data of 79 WSUs were included in the 2011 Database,

  2. established the Vienam Urban Water Supply Database for the year of 2011 including:

  1. input data on the performance of 79 urban water supply utilities over the nation;

  2. performance indicators of each of these 79 WSUs;

  3. National Indicators

  4. Regional Indicators for six regions over the nation, namely:

  • the Northern Mountainous and the Midland region;

  • The Red River Delta region;

  • the Central Coast region;

  • the Central highland region;

  • the East of Southern region; and

  • The Mekong River Delta region.

  1. The final report on assessment and analysis of the data and performance indicators

  1. established and maintained a formal website to publicize and update the Database at Additionally, a Manual on web-site usage for users has been provided: The “User Manual- Vietnam Ministry of Construction- Water Bench Marking System (December 2012)”
