The Zagreb project was implemented by IMGD, a Miya Group Company, based upon the following methodology:

• Analysis of the water utility assets, equipment and staff related to water loss.
• Water Balance analysis and calculation of performance indicators according to IWA WLTF methodology.
• Flow and pressure measurements in 10 temporary DMAs including key reservoirs in the system to determine losses in different zones.
• Full analysis of the results achieved in one DMA based on implemented measures of pressure control, remote monitoring and active leakage control.
• Planning for intervention activities and technical solutions to reduce water losses. This included DMAs, pressure control areas and solutions, measuring and monitoring locations and equipment, training and education of the water utility staff, use of appropriate methodology, leakage detection equipment, etc.
• Defining  priorities within the system for achieving fast loss reduction.
• Implementation of pressure control, monitoring and leakage detection in one DMA in the system.

During the implementation of the project, a special committee of 9 experts/engineers from the Zagreb water utility was trained in all aspects of the IWA methodology.
