PREPARATION OF PROGRAM FOR NON-REVENUE WATER REDUCTION IN 3 PRIORITY TOWNSIPS OF YANGON, MYANMAR
The project aims establishing a comprehensive Action Plan for reducing the NRW factor in Yangon City. It is based on surveys  and measurements done in 3 Townships located downtown supposed to be the more affected by NRW. It includes commercial and technical aspects of the NRW reduction strategy for a pilot zone representing:

  • 394 kms of network

  • 50 719 domestic customers

  • 676 019 persons


  • Description of WMI services


    • Construction of one rudimentary Domestic Meters Test Bench (DN 15 & DN 20 mm);
    • Domestic meters accuracy assessment (different positions) for 12 meters DN 20 mm;
    • Consumptions profiles (9 Domestic and 19 Non-Domestic);
    • Pressure Monitoring Program in 3 Townships (46 pressure measurements on hydrants);
    • Construction of 6 measurement chambers;
    • Flow/Pressure Measurements during 10 days in one Township (10 simultaneous measurement points):
      • 3 Ultrasonic flowmeters
      • 7 in-pipe insertion Electromagnetic flowmeters
    • Flow measurements during at least 4 days on 7 Tube Wells (Ultrasonic Flowmeter);
    • Hydraulic modeling of the 3 Townships (394 kms network length);
    • Pressure measurements during at least 4 days on 13 Pumping stations (modelling);
    • Detecting and locating physical leakages using helium gas tracking method.

    Key results


    • NRW reduction Action Plan established;
    • Preliminary Water Balance established with NRW at  75 % (including more than 85 % of Commercial Losses);
    • GIS and preliminary Hydraulic Model created for the Project area;
    • Rudimentary Domestic Test Bench installed;
    • YCDC staff trained for network optimization.
