Competitive Grant 9:

Reduction of NRW

FYR Macedonia - PUC Vodovod - Kumanovo

 

Description of the activity

The public utility company Vodovod Kumanovo is owned by the municipality of Kumanovo and is responsible for water supply and wastewater collection and treatment in the city. It received a grant from IAWD to start developing and implementing a comprehensive non-revenue water (NRW) reduction program in its water supply system. From 2010 to 2013, NRW amounted to around 60% of water flowing into the pipe system. Activities started in April 2014 and concluded in April 2015.

Implementation of the activity

The utility company Vodovod Kumanovo hired a consultant from Skopje to guide the company through a series of activities aimed at raising awareness for NRW issues and at reducing water losses.

In an initial classroom training session, managerial, technical and financial staff of the utility were introduced to aspects such as the IWA terminology on water loss management, different approaches for real loss and apparent loss control, and state of the art techniques and equipment used in leakage detection and control in the distribution system.

Could the participants of the 2015 Danube Water Conference exchange ideas about shared problems?

Subsequently, utility staff and the consultant together implemented a number of technical measures. In order to be able to manage the supply system more effectively, they divided it into three pressure zones and further into 23 District Meter Areas (DMAs). The team carried out flow and pressure measurements and could then approximate the level of leakage in each DMA. Demonstrating the methodology recommended by the IWA for use in the entire system, one DMA suffering from particularly high water loss was chosen as an example for detailed analysis and active leakage control. Within just this single DMA, the team achieved yearly water savings of close to 200,000 m3, representing 4.37% of Kumanovo’s entire physical water losses and worth over € 40,000 annually.

Building on this result, employees of the utility and volunteers of the Red Cross used the UN World Water Day on 22 March 2015 to distribute a leaflet informing citizens about water in general and about this project, explaining how to use water rationally, and appealing to them to pay their water bills.

Challenges and lessons learned

Staff training is instrumental for achieving sustainable results. This activity therefore focused on providing the utility with the means to further reduce NRW by taking action in one showcase DMA. Strong commitment by and within the utility will be necessary to extend these efforts to other DMAs. The utility will need to dedicate significant time to the process, and will need to procure some required equipment.

The technical and financial departments of the utility have shown this commitment to continue working on decreasing real and apparent losses after completion of the competitive grant project.
